PRECAUTIONS FOR OPERATION

PERMISSIBLE WATER DEPTH
When working in water or on swampy ground, do not let the water
come above the bottom of the axle housing (1).
After finishing the operation, wash and check the lubricating points.
IF WHEEL BRAKE DOES NOT WORK
If the machine is not stopped by depressing the brake pedal, use the parking brake to stop the machine.
NOTICE
If the parking brake has been used as an emergency brake, contact your Komatsu distributor to have the parking brake checked
for any abnormality.
PRECAUTIONS WHEN DRIVING UP OR DOWN SLOPES
LOWER THE CENTER OF GRAVITY WHEN TURNING
When turning on slopes, lower the work equipment to lower the center of gravity before turning. It is dangerous to
turn the machine suddenly on slopes.
BRAKING ON DOWNHILL SLOPE
If the footbrake is used frequently when traveling downhill, the brake will overheat and may be damaged. Place the
gearshift lever at a low speed range and use the braking force of the engine when traveling downhill.
Use the right brake pedal for braking.
If the brakes are used excessively, the brake oil temperature caution lamp may light up and the alarm buzzer may
sound intermittently. For details of the necessary action to take, see "BRAKE OIL TEMPERATURE CAUTION
LAMP (PAGE 3-18)" in EXPLANATION OF COMPONENTS.
If the speed range selected by the gearshift lever is not correct, the torque converter oil may overheat. If this
happens, shift down one gear range and reduce the oil temperature.
If the oil temperature does not return to the white range even when the gearshift lever is at 1st, stop the machine,
return the directional lever to the N position, and run the engine at a mid-range speed until the gauge returns to the
white range.
IF ENGINE STOPS
If the engine stops on a slope, apply the parking brake immediately, and lower the work equipment to the ground
and stop the machine. Then put the directional lever in neutral position, and start the engine again.
