FIG. 3

6

I. FOR SAFE OPERATION 1.9.

Inspect the lawn mower periodically. If not, this may not only shorten the lawn mower’s service life but also make safe and efficient operation impossible.

1.10. Never use the lawn mower out of normal usage even if it is not mentioned at this operator’s manual.

7

SXG326 & SXG323 2. BEFORE STARTING THE LAWN MOWER 2.1.

Set up an operation plan with sufficient time allowance. A tight plan may result in unexpected accidents. Especially when operating the lawn mower under extremely hot, cold, or humid circumstances, set up an operation schedule or method which will ensure operational safety.

2.2.

Mow only in daylight or good artificial light. Mowing in the dark may cause unexpected accidents.

2.3.

Thoroughly inspect the mowing area and remove all objects from the mowing area that the lawn mower can throw, such as stones, toys, sticks, and wires, which may lead to serious accidents.

2.4.

Ensure that there are no people or pets in the area where you will mow. Keep children out of the mowing area and under the watchful care of a responsible adult.

2.5.

Do not operate the lawn mower unless the operator’s presence controls, safety switches, and guards are attached and functioning properly.

2.6.

Start the engine from operator’s seat.

2.7.

Before starting the engine, make sure that everything is safe around the lawn mower and put the traction drive in neutral, apply the parking brake or parking lock, and disengage the cutting unit(s).

Otherwise, unexpected accidents may occur.

2.8.

Start the engine with the starter switch only.

Never attempt to start the engine by shorting the terminals, or the lawn mower may move abruptly, and result in unexpected accidents.

2.9.

Do not run the engine in an enclosed area where dangerous carbon monoxide fumes can collect.

Sufficient ventilation should be provided when starting the engine in an enclosed area.

2.10. Make sure of safety around the lawn mower and move slowly when starting. Abrupt starting may cause unexpected accidents.

2.11. Become familiar with the operation, particularly, the stopping of the lawn mower. You should be skilful enough to be able to stop the lawn mower at will.

FIG. 4

2.12. Use only attachments and accessories approved by the manufacturer and install and operate them as directed.

8

I. FOR SAFE OPERATION 2.13. Be sure to operate the lawn mower equipped with a standard mower deck and collector. Never mow grass without the collector, or the lawn mower scatters grass, stone and other flying debris, which is very dangerous. If you would like not to collect the cut glass in a collector, equip an optional discharge cover for collector.

Discharge cover for SBC550X-3L • (8664-705-200-00)........................................1pc Discharge cover for SBC600X-3H • (8664-755-500-10)........................................1pc 2.14. When your lawn mower is equipped with an implement other than a standard mower deck and collector, never fail to ask your dealer about machine balance. Always follow their advice.

2.15. Keep in mind that the operator or user is responsible for the accidents or hazards caused by the lawn mower to other people or their property.

2.16. Inspect the lawn mower for wear or damage.

Replace any worn or damaged parts.

2.17. Especially before starting the mower, be sure to perform advised pre-operation inspections especially on the brake and inspect visually to see that the blade and blade tightening nuts are not worn, damaged or loose. Replace worn or damaged blade and nuts as an assembly to preserve blade balance. Otherwise, poor braking or scattered broken blades may result, which is very dangerous.

9

SXG326 & SXG323 3. OPERATION OF THE LAWN MOWER 3.1.

When the lawn mower is running, stay away from the discharge opening, the cutting unit(s), and all moving parts.

3.2.

During operation, never allow anyone, especially children, and animals to be in the vicinity of the lawn mower. Do not direct the discharge at anyone.

3.3.

When you are working with coworkers, be sure to alert them by signalling before you take a new action.

3.4.

When boarding mower, please access from left side mower. When dropping from mower, please drop to left side mower.

3.5.

When operating the lawn mower, you should be seated in the operator’s seat properly, hold the steering wheel by both hands, and look in the direction in which the lawn mower advances. Avoid looking aside or holding the steering wheel by one hand during operation.

3.6.

Always be sure to operate the lawn mower from the operator’s seat. Never attempt to get on or off the lawn mower while it is travelling.

3.7.

Do not mow on wet grass. The lawn mower may slide.

3.8.

Slow down before turning the lawn mower. Turning at high speed may cause the lawn mower to turn over.

3.9.

Never attempt to depress the differential lock pedal while turning around the lawn mower. Turning with the differential lock on may cause the lawn mower to turn over.

FIG. 5

3.10. Look down and behind you and ensure a clear path before you move the lawn mower backward.

3.11. Do not mow while moving backward unless it is absolutely necessary.

3.12. Never operate the lawn mower in terrain where there are ditches, holes, or steps easy to collapse. In such a place, the lawn mower could turn over or fall.

3.13. Before making access to moving parts, stop the engine, and keep your hands, feet, clothing, accessories and etc. away so as not to be caught in the moving parts of the lawn mower.

10

I. FOR SAFE OPERATION 3.14. Be alert when you approach blind corners and objects that may obscure your vision. Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

3.15. Never rest a foot on the brake pedal. If so, the brakes wear rapidly, which may lead to serious accidents.

3.16. Never attempt to do the mowing operation without the discharge cover in place or with the cover left open.

3.17. Never attempt to operate without the drive shaft cover in place.

3.18. Do not attempt to adjust the cutting height while the engine is running.

3.19. Adjust the cutting height with the gauge wheels in accordance with the condition of the ground surface at the working site. Mowing on rough ground with low cutting height may cause the blades to hit soil or stones, which is very dangerous.

3.20. If you strike an object or if the lawn mower vibrates abnormally, stop the lawn mower immediately, wait for all moving parts to stop, and inspect the cutting unit(s). Make all repairs before you resume operation.

3.21. Be sure to keep the grass discharging part clean.

A clogged discharging part may cause the discharge cover to open, resulting in scattering of grass and stones, which is very dangerous.

3.22. Never allow grass or leaves to accumulate around heated parts such as the engine and the muffler, or this may cause a fire.

3.23. Before moving the lawn mower to another place, be sure to stop the mower blades and lift up the mower deck. Otherwise, they may hit stones and scatter them around, which is very dangerous.

3.24. When driving over a levee or a step, stop the mower blades, lift up the mower deck, and move the lawn mower straight to the levee and make it climb over slowly. Avoid climbing over a levee too high, or the lawn mower may fall sideways or turn over.

3.25. Stop the cutting unit(s) when you are crossing gravel areas 3.26. Watch for traffic when you are operating the lawn mower near a roadway or when crossing a roadway.

11

SXG326 & SXG323 3.27. Never attempt to use the lawn mower to draw an implement or a trailer. It is not designed to draw a load.

3.28. Stay alert and stop the lawn mower if people or animals enter the area.

3.29. Do not carry passengers.

3.30. Never carry children, even when the mower blades are not rotating. Children may fall off the lawn mower and become seriously injured or prevent you from operating the lawn mower safely.

Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the lawn mower.

3.31. When PTO is operating, maximum reverse traveling speed limits less than 0.3 m/s. Lawn mower with cutting width less than 1500 mm, except for zero turn and front mower, limits its reverse operation.

FIG. 6

3.32. If you use the lawn mower for long time, make sure to take rest every 2 or 3 hours.

3.33. When you hear thunder, stop the lawn mower and move indoors immediately. If you can not move indoors, get to low place. Otherwise, you can be struck by lightning.

3.34. Before stopping the engine, be sure to lower the mower deck onto the ground, apply the parking brake or parking lock, and move the PTO lever to the OFF position.

3.35. Before leaving the operating position of the lawn mower for any reason, always do the following: - Stop the lawn mower on level ground.

- Stop the cutting unit(s), disengage PTO, and lower the attachment(s).

- Disengage the drive(s).

- Apply the parking brake or parking lock.

- Stop the engine and wait for all moving parts to stop.

12

I. FOR SAFE OPERATION 4. OPERATION ON A SLOPE DANGER: Slopes are a major factor related to accidents with lawn mowers, resulting in severe injuries.

We cannot recommend the lawn mower with mower deck be operated on a slope. All slopes require extra caution; no slope is safe.

You can lose control of the lawn mower on a slope because of one of the following: - the wheels lack traction; you are driving the lawn mower too fast.

- you are not braking properly; the lawn mower type is not suited for the task.

- you are unaware of the ground conditions (especially slopes).

- you incorrectly hitch an attachment or distribute a load.

FIG. 7

If the lawn mower has to be used on a slope, never use it on a slope of more than “12°”. Even if using it on a slope of less than “12°”, be sure to abide by the following instructions.

A slope angle of 12°s specified with the lawn mowers equipped with the attachments mentioned respectively.

- The lawn mower is not equipped with any attachments or a cabin than a standard mower deck and collector.

- The lawn mower is equipped with a standard mower deck and collector.

Grass catchers and other attachments can change the stability of the lawn mower. Follow the instructions for adding weight to improve the stability of the lawn mower.

Parts code of weight Quantity Bumper 1728-410-360-00 SET Weight (15) 1614-922-200-20 SET

When your lawn mower is equipped with an implement other than a standard mower deck and collector, never fail to ask your dealer about machine balance. Always follow their advice.

The ROPS is a safety device.

- ‌ Keep the ROPS in the vertical and locked position. Always use the seat belt when you operate the mower.

Make sure the seat belt can be released quickly in an emergency.

- ‌ The ROPS should only be folded if absolutely necessary for storage. Do not operate the mower with the ROPS in the folded position. There is no roll over protection with the ROPS in the folded position.

- ‌ Do not use the seat belt with the ROPS in the folded position.

- ‌ Do not remove the ROPS from the mower.

(Recommended Seat : GS15 / GRAMMER) 4.1.

Be sure to wear a helmet during operation.

4.2.

If you feel uneasy operating your lawn mower on a slope, do not mow it.

13

1 3 (Max)

Note To equip weight, bumper set is required.

SXG326 & SXG323 4.3.

Evaluate the terrain to determine what accessories and attachments you will need to be safe.

4.4.

Do not mow near drop-offs, ditches, or embankments. You can tip the lawn mower over if a wheel is over the edge of a drop-off or if an edge caves in. Uneven terrain can cause the lawn mower to overturn.

4.5.

Never perform mowing operation on wet grass.

4.6.

Avoid sudden starting and stopping.

4.7.

Mow up and down a slope; do not mow across it.

4.8.

Mow a slope by moving slowly. Do not suddenly change your speed or direction.

4.9.

Do not turn on a slope unless it is necessary, and then, turn slowly downhill, if possible.

4.10. If the tires lose traction, disengage the cutting unit(s) and proceed slowly, straight down the slope. Do not apply the brake on the lawn mower that is sliding down a slope. Always keep the lawn mower in gear, especially when travelling downhill.

4.11. Do not use the grass catcher(s) while you are mowing a steep slope.

4.12. Do not try to stabilize the lawn mower by putting your foot on the ground.

4.13. Avoid stopping the lawn mower on a slope.

5. DRIVING ON PUBLIC ROADS 5.1.

This lawn mower cannot be driven on a public road without authorization by a local government agency. etc. Therefore it may be illegal for the lawn mower not only to travel on but also to cross a public road.

5.2.

When transporting the lawn mower on a public road, load it on a truck.

14

I. FOR SAFE OPERATION 6. LOADING ONTO OR UNLOADING FROM A TRUCK 6.1.

When loading the lawn mower onto a truck, turn off the truck’s engine, apply the parking brake to the truck, and chock the wheels to avoid unexpected moving of the truck.

6.2.

SXG326 & SXG323 7. WHEN FILLING WITH FUEL DANGER: Fuel is highly flammable and explosive. Take the following precautions.

7.1.

Do not add or drain fuel indoors, while smoking, or near a source of flame.

7.2.

Do not remove the fuel tank cap or add fuel to the tank while the engine is running or hot. Wait until the engine cools down sufficiently.

7.3.

Do not completely fill the fuel tank. Add fuel to the tank until the level inside the tank is just below the bottom of the filler neck. The empty space allows the fuel to expand.

7.4.

If you spill fuel, clean it up and do not attempt to start the engine until the vapour has dissipated.

7.5.

When fuelling under certain circumstances, a static charge may develop and ignite the fuel.

7.6.

Use only an approved fuel container to store fuel.

7.7.

Do not store the lawn mower or the fuel container near a source of open flame, such as a water heater.

7.8.

Replace all fuel tank and container caps securely.

FIG. 10

7.9.

To prevent personal injury and property damage, do the following: - Always place fuel containers on the ground and away from the vehicle before fuelling.

- Do not fill the fuel container(s) inside a vehicle or on a truck or trailer bed.

- When practical, remove a fuel-powered the lawn mower from the truck or trailer and refuel it with its wheels on the ground.

- If it is not practical to do this, refuel the lawn mower on a truck or trailer from a portable container, not fuel dispenser nozzle.

- If you must use a fuel dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or fuel container opening until you have completed fuelling.

9.13. The mower blades are sharp and can cut you. Wrap the mower blades or wear leather gloves when you service them. On the lawn mower with two or more mower blades, rotating one mower blades may cause the other mower blades to rotate.

9.14. Never step on the mower deck, or the mower deck may be damaged or deformed, which may lead to breakdown or accidents.

9.15. A first aid kit and a fire extinguisher should be kept in a place always in instant access.

9.16. On the lawn mowers with hydraulic devices, hydraulic fluid escaping under pressure can penetrate and seriously damage the skin, requiring immediate medical assistance. Do not use your hand to check for a hydraulic leak; use a piece of cardboard. Be sure to consult your dealer about the hydraulic and fuel injection system troubles.

9.17. If any hydraulic fluid is injected accidentally into the skin, it must be removed within a few hours by a doctor familiar with this type of injury.

18

I. FOR SAFE OPERATION 9.18. Never allow grass or leaves to accumulate around heated parts, such as muffler, engine and brake, and around terminals of battery, which have possibility of leakage of electricity by water.

Otherwise, it may cause a fire.

9.19. Replace any worn or damaged parts with the manufacturer’s recommended parts.

9.20. To reduce the fire hazard, keep the engine, muffler (silencer), battery area, and fuel storage area free of debris.

9.21. If fuel has to be drained, this should be done outdoors.

9.22. Check the brake(s) on the lawn mower frequently and adjust and service the brake(s) as required.

9.23. Replace faulty mufflers (silencers).

9.24. Do not change the engine governor settings or overspeed the engine. Operating an engine at an excessive speed can increase the risk of personal injury.

9.25. The grass catcher components are subject to wear and damage, exposing you to moving parts or thrown objects. Frequently check and replace them with the manufacturer’s recommended parts when necessary.

9.26. Be sure to reinstall the removed parts in place.

Never attempt to start the engine with any parts removed.

SCMA 54 SCMB 48

9.27. Never attempt unauthorized modification of the lawn mower as this could be very hazardous.

Damaged or worn parts should be replaced with ISEKI genuine spare parts. Unauthorized parts may cause breakdown of the lawn mower, accidents, and ISEKI warranty to expire.

(1) HST rod (2) Lock nuts

DANGER: • T he battery generates very explosive gases, so avoid smoking and keep sparks and open flames away from the battery.

Charging the battery should be done in a place well ventilated to disperse explosive gases as quickly as possible.

• Battery electrolyte is very corrosive and will cause burns, so if it splashes on skin or clothes, wash it off immediately. If acid contacts eyes, flush immediately with clean water and get medical attention.

• W hen using booster cables, take sufficient safety measures (Refer to page 20, 21 and 22).

(3) Trunnion arm

■ INSPECTION OF ELECTROLYTE LEVEL

k. Next, align both HST pedals in height by adjusting the effective length of the HST rod with the two lock nuts. Be sure to tighten the lock nuts securely after adjustment.

The battery is installed on the rear of the radiator of the lawn mower. Check to see if the electrolyte level is between the upper and lower limits. When the level is near to the lower limit or below, raise the level with distilled water to the upper limit.

l. Loosen the lock nut of the crank plate stopper bolt and screw in the bolt slightly to shorten the effective length.

55

SXG326 & SXG323 WARNING: Never attempt to keep on using or charging the battery with a electrolyte level lower than the limit, or the battery may explode or its service life be shortened due to deterioration inside the casing.

IMPORTANT: When storing tractor for long period without operation, self discharge of battery will happen (especially in winter). If the tractor is stored for more than 1 month, the battery minus terminal should be disconnected.

When operating for the first time or after long term storage, check if the battery charge level is enough. (If measurement of battery voltage is available, check if the voltage is more than 12.5V.) When the tractor is stored more than 6 months, charge the battery.

NOTE:

Do not throw away the battery to the garbage can.

Recycle it to follow the law of your community.

15. TIRE PRESSURE (INFLATION) (1) Battery (2) Upper limit

(3) Lower limit (4) Filler plug

Improper tire pressure causes abnormal wear of the tires and affects the lawn mower performance. Too high pressure causes the lawn mower to bounce too much and too low pressure increases travelling resistance,which leads to power loss.

IMPORTANT: The electrolyte level should always be kept between the upper and lower limits.

A too high level will cause the electrolyte to overflow and corrode other parts.

Tire pressure should be checked everyday.

SXG323 Tire size Pressure Front 16 x 6.50 -8 190 kPa Rear 23 x 10.50 -12 140 kPa

■ HANDLING OF THE BATTERY WARNING: • Be sure to connect the battery terminals correctly.

• T he wiring from the battery should be kept clean and connectors tight. Dirty or loose wiring may cause a fire.

• When disconnecting the battery, disconnect the negative terminal first and vice versa when connecting.

• When replacing the battery, use a battery of the same capacity as that of the current on (44B 19L).

SXG326 Front Rear

Tire size 18 x 8.50-8 26 x 10.50-12

Pressure 150 kpa 140 kpa

a. As atmospheric temperature lowers, the performance of the battery also lowers. Consequently the battery should be serviced with special care in wintertime. b. As the battery discharges even when it is not used, it should be charged every or every other month at the maximum.

WARNING: • Tire inflation should be set to the values specified in this manual. Excessive inflation may cause certain types to explode, which may result in serious accidents.

• Never use a tire with a cut or crack which reaches tire cords as such a tire may explode.

• When a tire, tube, or rim is required for replacement, ask your dealer. Such operation should be done by a mechanic trained especially for tire handling.

c. When the lawn mower is not used for a long time, remove the battery from the lawn mower and store it in a place dry and shaded from direct sunshine.

IMPORTANT: Avoid quick charge of battery. Or it will shorten the service life of the battery.

81

SCMA54&SCMB48&SCMC48 8. EFFICIENT MOWING

c. For mowing low moisture content grass or when there is much dead grass

IMPORTANT: • Be sure to mow at full throttle ( ).

• Choose an adequate travelling speed in accordance with the height or other conditions of grass to be cut.

• When the screens for the air-intake openings and radiator are clogged with dust, clean them at once. Never go on operating with clogged screens.

• Mowing is desirable when the grass is dew-free: in the afternoon or late afternoon, thus preventing the mower from heavy clogging.

• Always keep the mower deck clean.

• Check the blade ends for damage. (Refer to page 85 and 86.)

• Repeated mowing is recommended before the grass grows too high.

• Cutting grass too closely may damage the grass. To maintain a green lawn, never mow more than one-third of the height of the grass in one mowing.

• A slower travelling speed will result in improved mowing. Avoid selecting such a travelling speed that causes the lawn mower to bounce.

• Short or fast turns will damage turf. Slow down sufficiently when turning.

• Frequent sharpening of the mower blades results in beautiful finish and less load on equipment, which leads to economical operation.

i. Advance should be in a direction where the dust does not hit the operator by taking into consideration the direction of the wind. ii. When the air-intake screens are clogged, clean them at once.

IMPORTANT: • When operating the lawn mower in dusty circumstances, keep on paying attention to the coolant temperature warning lamp.

• Never continue operating when screens are clogged, or engine breakdown may result.

a. For mowing tall grass i. Mow grass twice.

First, mow the grass to a height low enough for the next finishing pass. Then finish to the desired grass height.

The second travelling pass should be shifted sideways by 20 cm (8 in.) or so, or travel perpendicular to the first passes, which will result in a beautiful even finish. ii. When trying to finish in one pass, select a sufficiently slow travelling speed. It may also be required to set the cutting width to half or one-third of that for normal operation. b. For mowing highly moist grass or mowing on wet ground i. If the turf damage by the tires could result, wait until the grass and land have dried sufficiently. ii. Wet grass requires a higher grass cutting height setting than when mowing dry grass, as the cutting height is often lower than expected during operation. iii. Select a sufficiently slow travelling speed and avoid sudden starts, turns, and stops. If not, the turf may be damaged.

82

III. MOWER OPERATION 9. HOW TO USE AIR INTAKE SCREEN a. In the normal mowing condition, mow the grass with the air intake screen (1) closed. b. When mowing at low cutting height, intake air from bottom of mower deck may become insufficient. In order to increase air circulation, loosen the knob nut (3) and rotate the air intake cover (2) to OPEN position.

After opening the air intake screen (1), tighten the knob nut (3) securely.
