• 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 ON MACHINE
• When performing maintenance work on the machine,
maintain the foothold clean and orderly to prevent falling.
Always observe the followings.
• Avoid spilling of oil and grease.
• Do not litter the tools.
• Watch your step when walking around on the ma-
chine.
• Remove mud and greases stuck to the shoe sole.
• Never jump down from the machine. When getting on and
off the machine, always face the machine and maintain at least three-point contact (both feet and one hand,
or both hands and one foot) with the handrails and steps to ensure that you support yourself.
• You must walk along the access aisle for checking being paved with non-slip pads. Never climb on the en-
gine hood and cover to prevent personal injuries from falling or failing over due to losing your footing.
PRECAUTIONS WHEN WORKING UNDER MACHINE
Machine or dump body may fall, and it is dangerous that seri-
ous personal injury or death may occur. Always observe the fol-
lowing.
• When performing inspection with the dump body raised, al-
ways set the dump control lever to “HOLD” position, set
the lock knob to 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 per-
son performing the inspection.
• Always perform the operation to remove or insert the body
pivot pin with at least 2 workers. This operation is performed 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 detail, see “BODY PIVOT PINS (3-117)”.
• 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.
• Never use concrete blocks for supports. Concrete blocks may break under even light loads.
