SAFETY GENERAL PRECAUTIONS PRECAUTIONS FOR ATTACHMENTS G When installing optional parts or attachments, there may be problems with safety or legal restrictions, so please contact your Komatsu distributor for advice. G Any injuries, accidents, or product failures resulting from the use of unauthorized attachments or parts will not be the responsibility of Komatsu. G When installing and using optional attachments, read the instruction manual for the attachment, and the gen- eral information related to attachments in this manual. UNAUTHORIZED MODIFICATION Any modification mode without authorization from Komatsu can create hazards. Before making a modification, consult your Komatsu distributor.
G Komatsu will not be responsible for any injuries, accidents, or product failures resulting from modifications made without authorization from Komatsu. G Do not carry out modifications of dump body such as wall raising. This will reduce the braking capacity or adversely affect the balance of the machine, and may lead to an expected accident. SAFETY AT WORKSITE Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous. G When carrying out operations near combustable materials such as thatched roofs, dry leaves or dry grass, there is a hazard of fire, so be careful when operating.
G 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. G 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. G Take necessary measures to prevent any unauthorized person from entering the operating area. G In particular, if you need to operate on a road, protect pedestrian and cars by designating a person for worksite traffic duty or by installing fences around the worksite.
G 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 operations. G Set and maintain the haul load on the jobsites so that the machine can always travel safely. WORKING ON LOOSE GROUND G 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.
G 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. 2-19
