a WARNING: Failure to follow these safety precautions may lead
to a serious accident. 6. GENERAL PRECAUTIONS
PRECAUTIONS FOR ROPS
Do not operate machine with ROPS removed if equipped.
The ROPS is installed to protect the operator if the machine should overturn. It is designed not
only to take the load when the machine overturns, but also to absorb the impact energy.
The Komatsu ROPS fulfills all worldwide regulations and standards, but if any unauthorized
modification is carried out on it, or if it is damaged when the machine overturns, its strength will
be reduced and it will not be able to provide its original capacity. It will be able to provide this
capacity only if modifications and repairs are carried out in the specified way.
When carrying out modification or repairs, always consult your Komatsu distributor first.
Even when the ROPS is installed, if you do not fasten your seat belt securely, it cannot protect
your properly. Always fasten your seat belt when operating the machine.
Seat belts --) See “27. USING SEAT BELT.”
PRECAUTIONS FOR ATTACHMENTS
l When installing and using an optional attachment, read the instruction manual for the attachment
and the information related to attachments in this manual.
l Do not use attachments that are not authorized by Komatsu or your Komatsu distributor. Use of
unauthorized attachments could create a safety problem and adversely affect the proper operation
and useful life of the machine.
l Any injuries, accidents, product failures resulting from the use of unauthorized attachments will
not be the responsibility of Komatsu.
l-7

6. GENERAL PRECAUTIONS A WARNING: For reasons of safety, always follow these safety precautions.
On machines equipped with an accumulator, for a short time after the engine is stopped, if the
work equipment control lever is moved to the LOWER position, the work equipment will move down
under its own weight.
After stopping the engine, always place the safety lock lever in the LOCK position.
When releasing the pressure inside the work equipment circuit on machines equipped with an
accumulator, follow the procedure given in the inspection and maintenance section.
Method of releasing pressure + See “11.16 HANDLING ACCUMULATOR.”
The accumulator is filled with high-pressure nitrogen gas, and it is extremely dangerous if it is
handled in the wrong way. Always observe the following precautions.
l Never make any hole in the accumulator or expose it to flame or fire.
l Do not weld any boss to the accumulator.
l When carrying out disassembly or maintenance of the accumulator, or when disposing of the
accumulator, it is necessary to release the gas from the accumulator. A special air bleed valve is
necessary for this operation, so please contact your Komatsu distributor.
Gas in accumulator -+ See “11.16 HANDLING ACCUMULATOR.”

7. PRECAUTIONS DURING
OPERATION A WARNING: Failure to follow these safety
precautions may lead to a serious accident.
7.1 BEFORE STARTING ENGINE
SAFETY AT WORKSITE
Before starting the engine, thoroughly check the area for any
unusual conditions that could be dangerous.
Before starting the engine, examine the terrain and soil con-
ditions of the worksite. Determine the best and safest method
of operation.
If you need to operate on a street, protect pedestrians and cars
by designating a person for worksite traffic duty or by install-
ing fences around the worksite.
If water lines, gas lines, and high-voltage electrical lines may
be buried under the worksite, contact each utility and identify
their locations. Be careful not to sever or cut any of these lines.
Check the depth and flow of water before operating in water
or crossing a river. NEVER be in water which is in excess of
the permissible water depth.
Permissible water depth + See “12.9.1 PERMISSIBLE WATER
DEPTH”.
Thoroughly remove wood chips, leaves, paper and other flammable things accumulated on the
engine compartment. They could cause a fire.
Check fuel, lubrication, and hydraulic systems for leaks. Have any leaks repaired. Wipe up any
excess oil, fuel or other flammable fluids.
Check point + See “12.1.1 WALK-AROUND CHECK”.
Be sure a fire extinguisher is present and working.
