SAFETY INFORMATION SAFETY CAB WINDOW GLASSES q If the cab glass on the work equipment side is broken, there is a hazard that the work equipment may contact the operator's body directly. Stop operation immediately and replace the glass. q The ceiling window is made of organic glass (polycarbonate), and as such it is apt to break easily when receiv- ing damage on the surface, thereby deteriorating its protective characteristic. If there is a crack or damage caused by a fallen rock, or when any sign of them is noticed, replace it with a new window. q If the cab door does not open for any reason, remove the glass from the rear window and use the window as an emergency escape exit.
For details, see "EMERGENCY EXIT FROM OPERATOR'S CAB (3-43)" in this manual. UNAUTHORIZED MODIFICATIONS Any modification made without authorization from Komatsu can create hazards. Before making a modification, consult your Komatsu distributor. q Komatsu will not be responsible for any injuries, accidents, product failures or other property damages result- ing from modifications made without authorization from Komatsu. SAFETY AT JOBSITE Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous.
q When carrying out operations near combustible materials such as thatched roofs, dry leaves or dry grass, there is a hazard of fire, so be careful when operating. q Check the terrain and condition of the ground at the worksite, and determine the safest method of operation. Do not carry out operations at places where there is a hazard of landslides or falling rocks. q If water lines, gas lines, or high-voltage electrical lines may be buried under the worksite, contact each utility and identify their locations. Be careful not to sever or damage any of these lines. q Take necessary measures to prevent any unauthorized per- son from entering the operating area.
q If any fire is lit near the machine, there is danger that sparks will be sucked in and cause a fire. Be extremely careful when handling flames. q When traveling or operating in shallow water or on soft ground, check the shape and condition of the bedrock, and the depth and speed of flow of the water before starting oper- ations. WORKING ON LOOSE GROUND q Avoid traveling or operating your machine too close to the edge of cliffs, overhangs, and deep ditches. The ground may be weak in such areas. If the ground should collapse under the weight or vibration of the machine, there is a hazard that the machine may fall or tip over.
Remember that the soil after heavy rain or blasting or after earthquakes is weak in these areas. q When working on embankments or near excavated ditches, there is a hazard that the weight and vibration of the machine will cause the soil to collapse. Before starting operations, take steps to ensure that the ground is safe and to prevent the machine from rolling over or falling. 2-18
