PRECAUTIONS FOR MAINTENANCE
TURN OFF ECSS SWITCH BEFORE PERFORMING INSPECTION AND MAINTE-
NANCE
Before starting the inspection and maintenance, lower the bucket to the ground and turn the ECSS switch to
OFF position, then stop the engine. Never turn the ECSS switch to ON position during the inspection or
maintenance.
PRECAUTIONS WHEN INSTALLING, REMOVING, OR STORING ATTACHMENTS
•
Appoint a leader before starting removal or installation operations for attachments.
•
Place attachments that have been removed from the ma-
chine in a stable condition so that they do not fall. And take
steps to prevent unauthorized persons from entering the
storage area.
PRECAUTIONS FOR WORKING AT HIGH PLACES
When working at high places, use a step ladder or other stand to ensure that the work can be performed safely.
There is a danger falling from high place that can lead to serious personal injury or death.
PRECAUTIONS WHEN WORKING UNDER MACHINE OR WORK EQUIPMENT
Machine or work equipment may fall, and it is dangerous that serious personal injury or death may occur. Al-
ways observe the following.
•
Do not perform inspection and maintenance under the work equipment which is not lowered to the ground.
Always lower the work equipment to the ground when performing inspection and maintenance.
•
Make sure the hoists or hydraulic jacks you use are in
good repair and strong enough to handle the weight of the
component. Never use hydraulic jacks at places where the
machine is damaged, bent, or twisted. Never use if the
strand of wire rope is frayed, twisted or pinched. Never use
bent or distorted hooks.
•
If it is necessary to raise the work equipment or a compo-
nent and then go under it to carry out inspection or mainte-
nance, support the work equipment or component securely
with blocks and stands (1) strong enough to support their
weight. If the work equipment or component is not support-
ed, they may come down, causing serious personal injury or death.
•
Never use concrete blocks for supports. Concrete blocks
may break under even light loads.
