WARNING: Failure to follow these safety precautions may lead to a serious accident. SAFETY 8.2 DURING MAINTENANCE Only authorized personnel can service and repair the machine. Do not allow unauthorized personnel into the area. If necessary, employ an observer. Extra precaution should be used when grinding, welding, and using a sledge hammer. ATTACHMENTS Appoint a leader before starting removal or installation operations 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 unauthorized persons from coming close. Stop the machine on firm, level ground, and lower all work equipment to the ground before performing service or repairs under the machine. Always block (1) the tires securely. It is extremely dangerous to work under the machine if the tires 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.
When carrying out operations with the work equipment or chassis raised, lock the front and rear frames with the safety bar, return the control levers to HOLD, set the control lever safety lock to the LOCK position, and block the work equipment and chassis. Block the wheels on the opposite side before jacking up. Set blocks under the machine after checking up. WA380-3MC 1-23 PERSONAL WORK UNDER THE MACHINE MAINTENANCE WITH CHASSIS RAISED
