GENERAL PRECAUTIONS COMMON TO OPERATION AND MAINTE-
NANCE SAFETY
PRECAUTIONS WHEN GETTING ON OR OFF MACHINE
USE HANDRAILS AND STEPS WHEN GETTING ON OR OFF MACHINE
To prevent personal injury caused by slipping or falling off the machine, always observe the following.
• Use the handrails and steps marked by arrows in the fig-
ure on the right 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 sup-
port yourself.
• Before getting on and off the machine, check the handrails
and steps if there is any oil, grease, or mud on them. Wipe
it off immediately not to slip if any. In addition, tighten any
loose bolt of the handrails and steps.
If the handrails and steps are damaged or deformed, they
need to be repaired immediately. Ask your Komatsu dis- ,&
tributor to perform this work.
• Do not grip the control levers or lock lever when getting on or off the machine. When getting on and off the
machine, be careful that your body or clothes do not touch the levers.
• Never climb on the engine hood or covers where there are no non-slip pads.
• Do not get on or off the machine with tools in your hand.
• Do not grab a foldable mirror as a handrail since it turns.
NO JUMPING ON OR OFF MACHINE
Getting on or off the moving machine can cause serious personal injury or death. Always observe the following.
• Never jump on or off the machine. Never get on or off a moving machine.
• If the machine starts to move when there is no operator on the machine, do not jump on to the machine and
try to stop it.
NO PEOPLE ON ATTACHMENTS
Never let anyone ride on the work equipment or other attachments. There is a hazard of falling and suffering
serious personal injury or death.

PRECAUTIONS FOR OPERATION SAFETY
PRECAUTIONS WHEN STARTING ENGINE
The machine may suddenly move off and this may lead to serious personal injury or death. Always observe the
following.
• Start the engine only while sitting down in the operator's seat.
• When starting the engine, sound the horn as a warning.
• Prohibit other personnel to get on the machine.
• Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause fire, serious
personal injury or death.
IN COLD WEATHER
• If the warm-up operation is not performed thoroughly, and the work equipment is operated, the reaction of
the work equipment to the operation of the control levers and pedals will be slow and the movement of it
may not be what the operator intended. Be sure to perform the warm-up operation. Particularly in a cold
weather, be sure the warming-up operation is completed.
• If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power
source. There is a hazard that this will ignite the battery and cause the battery to explode.
Before charging or starting the engine with a different power source, melt the battery electrolyte and check
that there is no leakage of electrolyte before starting.
START ENGINE WITH JUMPER CABLES
If any mistake is made in the method of connecting the jumper cables, it may cause the battery to explode, so
always observe the following.
• Always wear protective eyeglasses and rubber gloves
when starting the engine by using the jumper cables.
• When connecting a normal machine to a failed machine
with the jumper cables, always use the normal machine
with the same battery voltage as the failed machine.
• When starting the engine with the jumper cables, perform
the starting operation with 2 workers (one worker sitting in
the operator's seat and the other working with the battery).
• When starting from another machine, be careful that the
normal machine does not contact with the failed machine.
• When connecting the jumper cables, turn the starting
switch to OFF position for both the failed machine and the normal machine. If the failed machine has a bat-
tery disconnect switch, turn it to OFF position, and turn it ON again after connecting the cables.
It is dangerous that the machine may move when the power is connected.
• Be sure to connect the positive (+) cable first when installing the jumper cables. Disconnect the negative (-)
cable (ground side) first when removing them.
• When disconnecting the jumper cables, take care not to bring the clips in contact with each other or with the
machine.

PRECAUTIONS FOR OPERATION SAFETY
• Do not use the work equipment or swing to pull the load in
any direction. There is danger that the hook may break
and the load come off, causing the work equipment to
move suddenly and cause personal injury.
• Do not leave the operator's seat while the load is being lif-
ted.

PRECAUTIONS FOR MAINTENANCE SAFETY
PRECAUTIONS FOR DISPOSING OF WASTE MATERIALS
To prevent pollution, pay full attention to the way to dispose of waste materials.
• Always drain the oil from your machine in containers. Nev-
er drain the oil and coolant directly onto the ground or
dump into the sewage system, rivers, seas, or lakes.
• Obey appropriate laws and regulations when disposing of
harmful objects such as oil, fuel, coolant, solvent, filters,
batteries, and DEF.
Avoid exposure to burning rubber or plastics which produce a toxic gas that is harmful to people.
• When disposing of parts made of rubber or plastics (hoses, cables, and harnesses), always comply with the
local regulations for disposing industrial waste products.
METHOD FOR SELECTING WINDOW WASHER FLUID
Use an ethyl alcohol base washer liquid.
Methyl alcohol base washer liquid may irritate your eyes, so do not use it.
PERIODIC INSPECTION OF DEFINED LIFE PARTS
• To use the machine safely for a long period, be sure to periodically inspect the defined life parts that have
an especially close relation to safety, such as hoses and the seat belt. If an abnormality is found, replace it
immediately.
• The material of these components naturally changes over time, and repeated use causes deterioration,
wear, and fatigue. As a result, there is a hazard that these components can fail and cause serious personal
injury or death. It is not easy to judge the remaining life of these components but inspect them as much as
possible before work and at the regular maintenance.
• Replace or repair the defined life parts if a defect is found by the check.
