Foreword, safety and general information
Precautions to prevent fire
Fire caused by fuel, oil, coolant or window
washer fluid
Do not bring any flame or fire close to flammable
substances such as fuel, oil, coolant or window
washer fluid.There is danger that they may catch
fire. Always observe the following.
Do not smoke or use any flame near fuel or
other flammable substances.
Shut down the engine before adding fuel.
Do not leave the machine when adding fuel
or oil.
Tighten all the fuel and oil caps securely.
Be careful not to spill fuel on overheated
surfaces or on parts of the electrical system.
After adding fuel or oil, wipe up any spilled
fuel or oil.
Put greasy rags and other flammable
materials into a safe container to maintain
safety at the workplace.
When washing parts with oil, use a non-
flammable oil. Do not use diesel oil or
gasoline.There is danger that they may catch
fire.
Do not weld or use a cutting torch to cut any
pipes or tubes that contain flammable liquids.
Determine well-ventilated areas for storing oil
and fuel. Keep the oil and fuel in the
specified place and do not allow
unauthorized persons to enter.
When performing grinding or welding work
on the machine, move any flammable
materials to a safe place before starting.
Fire caused by accumulation or attachment
of flammable material

Fire coming from electric wiring
Short circuits in the electrical system can cause
fire. Always observe the following.
Fire caused by piping
Check that all the clamps for the hoses and
tubes, guards, and cushions are securely fixed
in position.
If they are loose, they may vibrate during
operation and rub against other parts. There is
danger that this may lead to damage to the
hoses and cause high-pressure oil to spurt out,
leading to fire and serious personal injury or
death.
Fire around the machine due to highly heated
exhaust gas
Some machines are equipped with KDPF
(Komatsu Diesel Particulate Filter).
KDPF is a system for purifying soot in exhaust
gas. Its
purification process (regeneration) can be at
higher temperature than that from existing
models. Do not bring any flammable material
close to the outlet of the exhaust pipe.
Explosion caused by lighting equipment
Remove any dry leaves, chips, pieces of
paper, coal dust, or any other flammable
materials accumulated or attached to or
around the engine exhaust manifold, muffler,
or battery, or on the undercovers.
To prevent fires from being caught, remove
any flammable materials such as dry leaves,
chips, pieces of paper, coal dust, or any
other flammable materials accumulated
around the cooling system (radiator, oil
cooler) or on the undercover.
Keep all the electric wiring connections clean
and securely tightened.
Check the wiring every day for looseness or
damage. Reconnect any loose connectors or
refasten wiring clamps. Repair or replace any
damaged wiring.
exhaust gas
When there are thatched houses, dry leaves
or pieces of paper near the work site, set the
system to disable the regeneration before
starting work to prevent fire hazards due to
highly heated exhaust gas.
See the operation and maintenance manual
for the setting procedure.
When checking fuel, oil, battery electrolyte,
or coolant, always use lighting equipment
with anti-explosion specifications.
When taking the electrical power for the
lighting equipment from the machine itself,
follow the instructions in the operation and
maintenance manual.
