IMPORTANT: Be sure to keep the removed parts.

III. MOWER OPERATION

1. BEFORE OPERATION

CAUTION:

• Before starting mowing operation, be sure to equip ISEKI standard grass collector. Never mow the grass without the collector or the lawn mower scatters grass, stone and other flying debris, which is very dangerous.

• Become familiar with how to operate the lawn mower and understand safety instructions by reading this manual carefully.

• Make sure that all safety covers and guards are installed in position.

• Make sure that the blade bolts are tightened securely.

• Before moving the lawn mower into the working site, check the whole area and get rid of all obstacles such as stones, wood, empty tins, bottles, wires, etc in older to assure safe operation.

• Make sure that the mower operation will not cause any injury to children, animals, bystanders, or damage to trees, buildings, etc.

• Check the place to mow for bumps, ditches, mounds, steps, slopes, inclination, softness, water pools, etc. ahead of time to avoid accidents such as turnover, fall, side-sliding of the lawn mower.

2. CUTTING HEIGHT ADJUSTMENT

b.Select one of the setting holes to get the required cutting height, insert the pin, and retain it with the spring clip pin. The label showing the relationships between the setting holes and cutting heights is stuck on the mower deck.

c. Also set the cutting height of the gauge wheels by re-setting the setting hole for the setting pin with the spring clip pin removed.

d.The right and left gauge wheels should be set to the same cutting height.

e.Lower the mower deck by the lift lever.

CAUTION: Before operating the lift lever, be seated in the operator’s seat and make sure of the safety conditions when lowering the mower deck.

3. STARTING MOWING OPERATION

a.Start the engine and turn the throttle lever to the intermediate position between the low speed (t) and high speed (r) positions.

IMPORTANT: When engaging the PTO clutch, slow down the engine speed sufficiently for safety.

IMPORTANT: When the lawn mower moves backward with engaging PTO, reverse speed limits to 0.3 m/s.

CAUTION: Whenever you encounter any trouble with the mower, ask your dealer for repair immediately.

WARNING: b.Pull the lift lever to raise the mower deck. h.Turn the throttle lever to the high speed (r) position to raise engine speed. i. As the HST forward travel pedal is depressed gradually, the lawn mower starts to travel. c. Release the parking brake. d.Push down the HST forward travel pedal gradually to drive the machine into the working site. e.Release the HST pedal gradually to stop the lawn mower. f. Lower the mower deck by the lift lever. g.Shift the PTO lever to the ON ( ) position.

• As soon as the PTO lever is shifted to the ON ( ) position, the mower blades start rotating and eject cut grass or stones through the discharge opening. Consequently, before operating the PTO lever make sure that there is no people, animals, or physical properties like buildings, cars, etc. within a range where ejected grass or stones may reach.

• The mower blades should be turned only on turf or grassland with the mower deck lowered.

CAUTION: Be sure to start mowing at sufficiently low speeds and increase travelling speed gradually.

NOTE: Before starting the operation, be sure to set the rear gauge wheels to forward and lock it by inserting pin, to prevent from damaging the grass.

IMPORTANT: The screens of the air-intake openings provided under the steering wheel, and the radiator screen should be kept clean. Never keep on operating with clogged screens, or the engine may be overheated, which may result in engine seizure.

4. CLEANING A MOWER DECK AND CHUTE CLOGGED WITH GRASS

When mowed grass is not ejected from the mower deck or the mower chute is clogged, stop operating immediately and remove clogged grass.

When the discharge opening inside chute (3) is clogged: a.Shift the PTO lever to the OFF ( ) position and move the lift lever upper to raise the mower deck in the highest position. b.Move the dump lever (6) downward or push the dump switch (LAE-type) to dump the collector. c. Stop the engine and remove the key. d.Pull up the cleaning lever (4) and remove the clogged grass (8) in the chute (3). e.Depress the Bottom plate, (9) downward and remove the clogged grass in the front portion of chute. f. Scrape out the staying grass with the cleaning stick,(7).

DANGER: Stop the engine and remove the key before removing the clogged grass in chute and mower deck.

5. EMERGENCY STOP

• When any of the following abnormalities is encountered, stop the machine and mower deck immediately.

- Abnormal noise

- Abnormal vibration

- Abnormal smell

- Blade hitting an obstacle

- The machine hitting an obstacle

• The cause of trouble should be located and corrected immediately. If not, consult your dealer. Never attempt to keep on operating the machine without locating and correcting the cause of trouble. After striking a foreign object, inspect the mower for damage and make repairs before restarting and operating mower.

• When the operator leaves the seat, the safety system automatically stops the engine. When leaving the machine to remove obstacles such as twigs, pebbles, etc., the PTO lever must be shifted to the OFF position and the parking brake applied.

6. STOPPING MOWING OPERATION

a.Release the HST pedal.

b.Turn the throttle lever to the low speed position (t) to reduce the engine speed.

c. Lock the brake pedal.

CAUTION: Park the machine on level, hard ground and make sure that the locking of brake pedal is applied securely.

d.Shift the PTO lever to the STOP ( ) position.

e.Turn the key switch to the STOP ( ) position to stop the engine.

IMPORTANT: •Never attempt to stop the engine abruptly when it is running at high speeds.

•Be sure to let the engine idle for about 5 minutes after long operation and then stop the engine. Abrupt engine stopping may lead to overheating causing seizure.

f. Remove the starter key without fail.

7. EFFICIENT MOWING

IMPORTANT: a. For mowing tall grass i. Mow grass twice. 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 on wet ground i. If the turf damage by the tyres 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. c. For mowing low moisture content grass or when there is a lot of dead grass 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.

•Be sure to mow at full throttle (r).

•Choose an adequate traveling 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 75 and 76.)

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

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

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

•Short, fast turns will damage the 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.

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.

IMPORTANT: •When operating the machine 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.

IV. INSPECTION AND MAINTENANCE OF MAJOR PARTS

CAUTION:

• When servicing the machine, place it on level, hard ground.

• Stop the engine and remove the starter key.

• Apply the parking brake securely.

• Push down (d) the lift lever to lower the mower to the ground.

• Shift the PTO lever to the STOP position ( ).

• Service the machine after the engine has cooled down sufficiently.
