PRECAUTIONS FOR MAINTENANCE
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 performed safely.
PRECAUTIONS WHEN WORKING ON TOP OF MACHINE
Clean up the machine to prevent falling off when performing
maintenance, always observe the following.
Do not spill oil or grease.
Do not scatter the tools.
Be careful at the time of the walk on the step.
Remove mud and the oils and fats kind of the bottom of
shoes.
Never jump off the machine. When getting on or off the machine,
maintain at least 3-point contact (both feet and one hand, or both
hands and one foot) with the handrail and steps to ensure that
you support yourself.
To prevent personal injury or death caused by slipping or falling off the machine, never climb on the engine hood
or covers except the check passage with non-slip pads.
PRECAUTIONS WHEN WORKING UNDER MACHINE OR WORK EQUIPMENT
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 element
wire of wire rope is frayed, twisted or pinched. Never use bent or
distorted hooks.
It is extremely dangerous to work under the machine if the track
shoes are lifted off the ground and the machine is supported
only with the work equipment. If any of the control levers is
touched by accident, or there is damage occurring to the
hydraulic piping, the work equipment or the machine will
suddenly drop. This is extremely dangerous. Never work under
the work equipment or the machine.
If it is necessary to raise the work equipment or the machine and then go under it to perform inspection or
maintenance, support the work equipment and machine securely with blocks and stands strong enough to
support the weight of the work equipment and machine.
If the work equipment and machine are not supported, there is a hazard that they may come down and that this
may lead to serious personal injury or death.
Never use concrete blocks for supports. They can collapse under even light loads.
