SAFETY
PRECAUTIONS FOR MAINTENANCE
2-25
TWO WORKERS FOR INSPECTION AND MAINTENANCE WHEN ENGINE IS RUNNING
q
Lower the work equipment to the ground and stop the
engine.
q
Operate work equipment lock lever (1) and parking brake
lever (2) to the LOCK (L) position.
q
Keep away from rotating parts.
q
Do not touch the control levers except when it is necessary
to do so to carry out an inspection or maintenance work.
q
Do not drop or insert any tools or parts.
WORK UNDER THE MACHINE
q
Whenever it becomes necessary to go under the raised
machine or work equipment, be sure to support them with
blocks sturdy enough to withstand their weight. If it is
neglected to support them, the machine or work equipment
may fall off, causing a serious personal injury or death.
q
Never use concrete blocks for supports. They can collapse
under even light loads.
q
Make sure the hoists or jacks you use are in good repair and strong enough to handle the weight of the com-
ponent. Never use jacks with cracked, bent or twisted parts. Never use frayed, twisted or pinched cables.
Never use bent or distorted hooks.
q
When the track shoe is lifted using the work equipment, do not go under the machine. Otherwise, when it is
lowered, there is danger that a serious personal injury or death may be caused.
