• 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 hand-
rails 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 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.
• Make sure the hoists or hydraulic jacks you use are in good condition 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 con-
trol levers is touched by accident, or there is damage oc-
curring to the hydraulic piping, the work equipment or the
machine will suddenly fall. Never work under the work
equipment or the machine.
• If it is necessary to raise the work equipment or the ma-
chine and then go under it to perform inspection or mainte-
nance, 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, they may come down and it may cause serious per-
sonal injury or death.
• Never use concrete blocks for supports. Concrete blocks may break under even light loads.
USE PROPER TOOLS
Use the tools suited to the task and use them correctly. Using
damaged, deformed, or low quality tools, or making improper
use of the tools may cause serious personal injury or death.
