hammer.
●
Always wear safety glasses when grinding parts with a

experienced welder carry out the work. When carrying
out welding work, always wear welding gloves, apron,
glasses, cap and other clothes suited for welding work..
4. When carrying out any operation with two or more
workers, always agree on the operating procedure
before starting. Always inform your fellow workers
before starting any step of the operation. Before starting
work, hang UNDER REPAIR signs on the controls in
the operator's compartment.

removed parts. Always keep the tools and parts in their
correct places. Always keep the work area clean and
make sure that there is no dirt or oil on the floor. Smoke

PREPARATIONS FOR WORK
00
1. Before adding oil or making repairs, park the machine
on hard, level ground, and block the wheels or tracks to
prevent the machine from moving.
2. Before starting work, lower blade, ripper, bucket or any
other work equipment to the ground. If this is not
possible, insert the safety pin or use blocks to prevent
the work equipment from falling. In addition, be sure to
lock all the control levers and hang warning signs on
them.
3. When disassembling or assembling, support the
machine with blocks, jacks or stands before starting
work.
4. Remove all mud and oil from the steps or other places
used to get on and off the machine. Always use the
handrails, ladders or steps when getting on or off the
machine. Never jump on or off the machine. If it is
impossible to use the handrails, ladders or steps, use a
stand to provide safe footing.
PRECAUTIONS DURING WORK
00
1. When removing the oil filler cap, drain plug or
hydraulic pressure measuring plugs, loosen them slowly
to prevent the oil from spurting out. Before
disconnecting or removing components of the oil, water
or air circuits, first remove the pressure completely from
the circuit.
2. The water and oil in the circuits are hot when the engine
is stopped, so be careful not to get burned. Wait for the
oil and water to cool before carrying out any work on
the oil or water circuits.
