SAFETY INFORMATION
Fire coming from electric wiring
Short circuits in the electrical system can cause fire.
Always keep electric wiring connections clean and securely tightened.
Check the wiring every day for looseness or damage. Tighten any loose connectors or wiring clamps. Repair
or replace any damaged wiring.
Fire coming from hydraulic line
Check that all the hose and tube clamps, guards, and cushions are securely fixed in position.
If they are loose, they may vibrate during operation and rub against other parts. This may lead to damage to the
hoses, and cause high-pressure oil to spurt out, leading to fire damage or serious injury.
Explosion caused by lighting equipment
When checking fuel, oil, battery electrolyte, window washer fluid, or coolant, always use lighting with
anti-explosion specifications. If such lighting equipment is not used, there is danger of explosion that may
cause serious injury.
When taking the electrical power for the lighting from the machine itself, follow the instructions in this manual.
ACTION IF FIRE OCCURS
If a fire occurs, escape from the machine as follows.
Turn the start switch OFF to stop the engine.
Use the handrails and steps to get off the machine.
WINDSHIELD WASHER FLUID
Use an ethyl alcohol base washer liquid.
Methyl alcohol base washer liquid may irritate your eyes, so do not use it.
FALLING OBJECTS, FLYING OBJECTS AND INTRUDING OBJECTS PREVENTION
On jobsites where there is a hazard that falling objects, flying
objects, or intruding objects may hit or enter the operator's cab,
consider the operating conditions and install the necessary guards
to protect the operator.
When carrying out demolition or breaker operations, install a
front guard and use a laminated coating sheet on the front glass.
When working in mines or quarries where there is a hazard of
falling rock, install FOPS (Falling Objects Protective Structure)
and a front guard, and use a laminated coating sheet on the front
glass.
When carrying out the above operations, always close the front
window. In addition, always ensure that by standers are a safe
distance away and are not in hazard from falling or flying
objects.
The above recommendations assume that the conditions are for
standard operations, but it may be necessary to add additional
guards according to the operating conditions on the jobsite.
Always contact your Komatsu distributor for advice.
