Keep objects away from moving fan blades. The fan blades will
throw objects and the fan blades can cut objects.
Do not use a wire rope cable that is kinked or flayed. Wear
gloves when you handle a wire rope cable.
When you strike a retainer pin, the retainer pin might fly out. The
loose retainer pin can injure personnel. Make sure that area is
clear of people when you strike a retainer pin. To avoid injury to
your eyes, wear protective glasses when you strike a retainer
pin.
Track Tension Adjustment Requires
Caution
Never turn out the track tension grease valve. To release
pressure from the crawler frame track tension assembly, you
should NEVER attempt to disassemble the track adjuster or
attempt to remove grease fitting or valve assembly.
Keep your face and body away from the valve. Refer to the
track adjustment procedure in the Operator and Maintenance
Manual or Shop Manual.
Supports and Blocks for Work Equipment
Do not allow weight or equipment loads to remain suspended.
Lower everything to the ground before leaving the operator's
seat.
Do not use hollow, cracked or unsteady wobbling supports.
Do not work under any equipment supported only by a lifting
jack.
Action When Abnormality Is Found During
Inspection
If any abnormality is found during inspection, always carry out
repairs. In particular, if the machine is used when there are still
problems with the brake or work equipment systems, it may
lead to serious injury.
If necessary depending on the type of failure, please contact
your DOOSAN distributor for repairs.
