SAFETY
S-24
Check Emergency Engine Stop Switch:
•
If a fire breaks out, failure to release pressurized air in-
side the hydraulic tank will escalate fire, hampering fire
fighting.
•
Check the emergency engine stop switch function
every 250 hours:
1) Start the engine and run it at slow Idle.
2) Turn the emergency engine stop switch to the
EMERG. STOP position.
3) Confirm that both engines stop and that pressur-
ized air inside the hydraulic oil tank is released (a
hissing sound should be heard).
•
If any abnormalities are found, be sure to repair them
before operating the machine.
Check Heat Shields:
•
Damaged or missing heat shield may lead to fires.
•
Damaged or missing heat shields must be repaired or
replaced before operating the machine.

EVACUATING IN CASE OF FIRE
•
If a fire breaks out, evacuate the machine in the following
way:
•
Stop the engine by turning the key switch to the OFF
position if there is time.
•
Use a fire extinguisher if there is time.
•
Exit the machine.
•
In an emergency, if the cab door or front window can not
be opened, break the front or rear window panes with the
emergency evacuation hammer to escape from the cab.
Refer the explanation pages on the Emergency Evacua-
tion Method.

BEWARE OF EXHAUST FUMES
•
Prevent asphyxiation. Engine exhaust fumes can cause
sickness or death.
•
If you must operate in a building, be sure there is ade-
quate ventilation. Either use an exhaust pipe extension
to remove the exhaust fumes or open doors and win-
dows to bring enough outside air into the area.
