SAFETY PRECAUTIONS FOR MAINTENANCE WARNING: Failure to follow these safety precautions may lead to a serious accident. ATTACHMENTS Appoint a leader before starting removal or installation opera- tions for attachments. Do not allow anyone other than the workers close to the machine or attachment. Place attachments that have been removed from the machine in a safe place so that they do not fall. Put a fence around the attachments, and set up No Entry signs to prevent unautho- rized persons from coming close. A0055130 WORK UNDER THE MACHINE Stop the machine on firm, level ground, and always lower all work equipment to the ground before performing service or repairs under the machine.
Always block the track shoes securely. It is extremely dangerous to work under the machine if the track shoes are off the ground and the machine is supported only by the work equipment. Never work under the machine if the machine is poorly supported. A0055140 WORK ON TOP OF MACHINE When carrying out maintenance on top of the machine, make sure that the footholds are clean and free of obstructions, and follow the precautions below to prevent yourself from falling. Do not spill oil or grease. Do not leave tools lying around. Mind your step when you are walking. Never jump down from the machine.
When getting on or off the machine, always use the steps and handrails, and main- tain three-point contact (both feet and one hand or both hands and one foot) at all times. AD305870 Use protective equipment if necessary. LOCKING INSPECTION COVERS When carrying out maintenance with the inspection cover open, lock it securely with a lock bar. If maintenance is carried out with the inspection cover open and not locked in position, it may close suddenly if knocked or blown by the wind, and may cause injury to the operator. 45
