METHOD FOR OPERATING BUCKET
Position (e): TILT
When the multifunction mono-lever is pulled further from the
“TILT” position, the lever stops in that position. As soon as the
bucket reaches the position preset by the bucket positioner, the
lever returns to the “HOLD” position.
Position (b): HOLD
The bucket remains in the position where it was stopped.
Position (f): DUMP
PRECAUTIONS FOR OPERATION
PERMISSIBLE WATER DEPTH
When operating the machine in water or on swampy ground,
do not move it to a place where the water depth is beyond the
permissible level (up to the bottom surface of axle housing (1)).
After finishing the operations, wash the machine and lubricate
the parts that have been exposed to water.
If the brake creaks, change all of the axle oil.
IF BRAKE DOES NOT STOP MACHINE MOVE
If the machine is not stopped by depressing the brake pedal, use the parking brake to stop the machine.
NOTICE
If the parking brake was used as a secondary brake, ask your Komatsu distributor to inspect the park-
ing brake system for any trouble.
PRECAUTIONS WHEN TRAVELING ON SLOPES
LOWER CENTER OF GRAVITY WHEN STEERING MACHINE
When turning the machine on a slope, lower the work equipment to lower the center of gravity before turning.
Turning on a steep slop is dangerous and, thus, prohibited.
TRAVEL DOWNHILL
If you use the foot brake too frequently during downhill travel, the brake may be overheated and damaged.
Use the accelerator pedal effectively for better braking performance during traveling.
If the brake oil temperature caution lamp lights up and the alarm buzzer sounds intermittently because of fre-
quent use of the brake, take proper actions according to “BRAKE OIL TEMPERATURE CAUTION LAMP” in
“EXPLANATION OF COMPONENTS”.
