Komatsu — 7.2 OPERATING MACHINE

WARNING: Failure to follow these safety precautions may lead to a serious accident. SAFETY ! Always position a signal man for dangerous areas or places where the view is not clear. ! Make sure that no one comes inside the swing radius or travel path. ! Before starting to move, sound the horn or give a signal to warn people not to come close to the machine. ! There are blind spots behind the machine. Check for objects and personnel behind the machine before traveling in reverse. ! Never turn the starting switch to the OFF position when traveling. It is dangerous if the engine stops when the machine is traveling. It will be impossible to operate the steering. !

It is dangerous to look at other things when operating. Always concentrate on your work. It is dangerous to drive too fast, start suddenly, stop suddenly, turn suddenly, or snake when driving the machine. ! If any abnormality in the machine (noise, vibration, smell, abnormality in gauges, leakage of air or oil, etc.) is seen during operations, stop the machine immediately at a safe place and look for the cause. ! Keep the work equipment at a height of 40 to 50 cm (16 to 20 in) from the ground level. ! When traveling, do not operate the work equipment levers. If the work equipment levers have to be operated, stop the machine before operating them. ! Do not operate the steering suddenly.

The work equipment may hit the ground and cause the machine to lose its balance, and this may damage the machine or structures in the area. ! When traveling on rough ground, travel at low speed, and avoid sudden changes in direction. Avoid traveling over obstacles as far as possible. If the machine has to travel over an obstacle, keep the work equipment as close to the ground as possible and travel at low speed. Never travel over obstacles which make the machine tilt strongly (10 E or more). When traveling and during operations, always keep a good distance to prevent contact with other machines and structures. ! Drive slowly enough to insure complete control.

Slow down when traveling in congested areas or on mud, ice or other slippery surfaces. Keep a safe distance away from other vehicles, according to the load and ground conditions. ! Always keep to the permissible water depth. Permissible water depth ! See 12.12 PRECAUTIONS FOR OPERATION on page 2-78 ! When traveling over bridges or structures on private land, check that the bridge or structure can withstand the machine weight. When traveling on public roads, check with the local authorities and follow their instructions. 1-13 CHECK THAT NO ONE IS IN AREA BEFORE SWINGING OR TRAVELING IN REVERSE PRECAUTIONS WHEN TRAVELING
