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 3
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.
BREAKING ON DOWNHILL SLOPE
If the foot brake is used frequently when traveling downhill, the brake will overheat and may be damaged. Use the
accelerator pedal to make full use of the braking force of the engine when traveling downhill.
Use the right brake pedal for braking.
If the brakes are used excessively, the axle oil temperature caution lamp may light up and the alarm buzzer may
sound intermittently. For details of the necessary action to take, see “AXLE OIL TEMPERATURE CAUTION LAMP
(3-16)“ in EXPLANATION OF COMPONENTS.
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.
