Typical operations

2- Move the blade to the extreme right, then move the circle to the right, until the cylinder rod has a protrusion of 127 mm (5 inches) and lower the blade to the ground with a light pressure.

Blade positioned to one side of the motorgrader

3- Disengage the saddle lock pin and, using the blade raise lever, extend the right hand cylinder rod and retract the left hand cylinder rod (blade on the ground), to turn the sadlle. After the saddle has been turned to the desired position, align the pin holes and reengage the lock pins.

Saddle 4- Slightly raise the blade off the ground then raise the right hand end of the blade. At the same time, turn the circle such that the right hand end of the blade moves toward the front of the motorgrader (this will prevent the left hand end of the blade from hitch the ground).

Simultaneously move the circle up using the side shift lever (in this case, pull the circle side shift lever toward the rear).

NOTE: As the left end of the blade gets a clearance from the ground, it will be necessary to simultaneously lower the left end of the blade when raising the right end.

Blade in 900 slope position

5- Proceed with the operation (as in item 4) until the blade is positioned as shown in the illustration. then, turn the blade (using circle rotation) to the desired position.

IMPORTANT: During backfill operations, improved control of the blade may be possible by using the angle of the front wheels to push the blade in the direction required or moving it away from the fill.

SCARIFYING

To scarify any surface, it will be best to use more teeth with a shallower penetration than fewer teeth with a deeper penetration. Also it would be best to brake the surface of the material into smaller lumps.

When the scarifier is used in crowded urban areas, use care with shallow manholes, sewers and other utilities.

Use the lowest gear (1st gear) with engine at high speed for improved control of the motorgrader and also for improved breaking up of the surface of the material. The teeth of the scarifier should be in good condition for best results. Never drag the teeth rearward. This may seriously damage the attachment bar.

When operating the machine and it is necessary to negotiate a curve, slow down and angle the front wheels toward the curve. After completing the curve, straighten up the front wheel to the original position and resume normal ground speed.

When moving the motorgrader to one location to the other, keep the blade within the width limit of the machine, and raised as high as possible.

When driving or operating the motorgrader on the road, always move the hand throttle to a low speed position, select the desired gear then use the throttle/ decelerator to control machine speed.

Ensure the speed system is operating properly to allow engine speed to return to idling when the operator releases the throttle/dethrottle pedal.

When operating the motorgrader, follow traffic rules and be alert to the traffic of other vehicles. Be ready for any emergency.

If the motorgrader is used for maintenance work on crowded areas or roads, put up warning signs. Keep an eye on the traffic of other vehicles, particularly before turning or changing direction of travel or when working inside the traffic.

STOPPING AND PARKING THE MOTORGRADER

Park the motorgrader in the desired parking area. Position the blade with the ends inside the limits of the length between the wheels, then lower the blade to the ground.

Move the gear selector lever to neutral.

OPERATION

Prior to switching of the engine, keep it running at 1/ 4 throttle during 3 or 4 minutes for the engine to cool down gradually. Then, move the throttle lever to idle and turn fuel key switch a OFF stop the engine.

Switch off the starter switch, remove the switch key and engage the parking/emergency brake. Turn the master battery switch to the OFF position and lock the master battery switch casing door behind the left hand battery case.

Check ROPS attaching bolts after the first 50 operating hours and thereafter at regular intervals.

ROPS attaching bolts torque is 50.8 da.Nm (52.6 kgm) (375 lb.ft). If the enclosed cab is installed, keep all cab accessories, such as windscreen wipers, sliding bolts, glass, hinges, seat belts, etc. in good condition. Keep glass panels clean at all times.

If any glass replacements are required, use only safety glass or equivalent.

CAUTION

COLD WEATHER OPERATION

Machine cooling system is factory filled with a 50% mixture of water and 50% ETHYLENE GLYCOL. The ETHYLENE GLYCOL product protects the engine down to a temperature of -34oC (-30oF). This solution must not be drained prior to operating the unit.
