•
Lead-acid batteries produce flammable and explosive
gases.
•
Keep arcs, sparks, flames and lighted tobacco away from
batteries.
•
Batteries contain acid which burns eyes or skin on contact.
•
Wear protective clothing. If acid contacts body, flush well
with water. For eye contact flush well and get immediate
medical attention from a physician familiar with this injury.
•
The maintenance procedures which are given in this
manual can be performed by the owner or operator without
any specific technical training. Maintenance procedures
which are not in this manual must be performed ONLY BY
QUALIFIED SERVICE PERSONNEL. Always use genuine
DOOSAN replacement parts.
•
Only authorized personnel should service and repair the
machine. Do not allow unauthorized personnel into work
area.
•
Lower work equipment and stop engine before performing
maintenance.
•
Park machine on firm and level ground.
•
Turn starter switch to "ON' position and keep safety lever in
"UNLOCK" position. Cycle work levers (joysticks) back and
forth, left and right at full stroke 2 to 3 times to eliminate
remaining internal pressure in hydraulic circuit.
Then move safety lever to "LOCK" position.
•
Check that battery relay is "OFF" and main power is shut
off. (Wait for approximately one minute after turning "OFF"
engine starter switch key and press horn switch. If horn
does not sound, the main power is shut off.)
•
Put blocks under track to prevent the machine from
moving.
•
To prevent injury, do not perform maintenance with engine
running. If maintenance must be done with engine running,
perform maintenance with at least two workers and do the
following:
–
One worker must always sit in the operator's seat and
be ready to stop engine at any time. All workers must
maintain contact with other workers.
–
When maintenance operations are near fan, fan belt,
or other rotating parts, there is a potential hazard of
being caught in rotating parts. Keep hands and tools
away.
•
Never drop or insert tools or other objects into rotating fan
or fan belt. Parts can break off and hit someone.
•
Do not touch any control levers or control pedals. If any
control levers or control pedals must be operated, always
give a signal to other workers and instruct them to move
away.
