SAFETY
PRECAUTIONS FOR MAINTENANCE
INSTALLING, REMOVING, OR STORING ATTACHMENTS
Appoint a leader before starting removal or installation
operations for attachments.
Place attachments that have been removed from the machine in
a stable condition so that they do not fall. And take steps to
prevent unauthorized persons from entering the storage area.
PRECAUTIONS WHEN WORKING AT HIGH PLACES
When working at high places, use a step ladder or other stand to ensure that the work can be carried out safely.
PRECAUTIONS WHEN WORKING UNDER MACHINE
When carrying out inspection with the dump body raised, always
set the dump control lever to the HOLD position, set the lock
knob to the LOCK position, then insert the body pivot pin. If the
body pivot pin is not inserted, the dump body may go down when
the dump control lever is operated, and catch or cause serious
injury or even death to the person carrying out the inspection.
Always carry out the operation to remove or insert the body pivot
pin with at least two workers. This operation is carried out with
the dump body raised, so if the dump body comes down during
the operation, it may lead to serious injury or even death.
For details, see "BODY PIVOT PIN (PAGE 3-44)".
Make sure the hoists or jacks you use are in good repair and strong enough to handle the weight of the
component. Never use jacks at places where the machine is damaged, bent, or twisted. Never use frayed, twisted
or pinched wire rope. Never use bent or distorted hooks.
Never use concrete blocks for supports. They can collapse under even light loads.
PROPER TOOLS
Use only tools suited to the task and be sure to use the tools
correctly. Using damaged, deformed, or low quality tools, or
making improper use of the tools may cause serious personal
injury.
