Komatsu — 2.3. OPERATING THE MACHINE

SECTION 2 SAFETY PRECAUTIONS Page 6 OPERATING THE MACHINE Never shift the transmission direction lever into neutral when travelling downhill. The machine may go out of control and a rollover could result or the transmission, torque converter or engine could be damaged when the transmission is again placed in gear. Always put the transmission in the low range position before starting downhill. Use the accelerator pedal and brake pedal to slow the machine. Never haul passengers. Only the operator should be on the machine when it is moving. If the brake system warning light and buzzer come on during operation, immediately stop the machine in a safe place. Apply the parking brake.

Correct the cause before operating again. Lock the levers when roading the machine so as not to actuate the levers accidentally. Maintain clear vision of all work and travel areas. Keep the windows and mirrors clean and repaired. Look in the mounted equipment control intended travel direction to be sure the personnel and allied equipment do not interfere with the machine's work pattern. Do not operate if exposed personnel enter the immediate work area. When traveling fast or downhill never apply the brake and transmission disconnect pedal as this shifts the transmission into neutral (N).

The machine could go out of control or the power train could be damaged when the pedal is released and the transmission is shifted into gear again. Do not drive the machine without checking the brakes for correct operation. Avoid sidehill travel whenever possible. Drive straight up and down the hill. If the machine starts slipping sideways, turn downhill immediately, and lower the bucket. Do not overspeed the engine. Excessive speeds can be hazardous and harmful to the power train. Select the proper gear before starting downhill. Control the speed with the brakes. Avoid crossing obstacles such as ditches, ridges, curbs, logs, rocks, and railroad tracks.

If you cannot avoid them, reduce speed and cross at an angle. Never use the bucket as a brake except in an emergency. Do not adjust the seat while the machine is moving because a loss of control may result. Stop the machine, apply the parking brake and then adjust the seat. Never allow anyone to stand on the ladder when the bucket is raised or the machine is moving. Carry the bucket low for maximum visibility and stability when traveling. Use extra caution when moving with the bucket raised. The stability is reduced as the bucket is raised. Know the traffic flow patterns of the job site. Obey flagmen, signs and signals. There is no substitute for good judgment when working on a slope.

Slope operation should be limited according to the ground and traction conditions, the load being carried, and the speed of the machine. OM515C520C99/1E DRESSTA
