Crushing Prevention and Cutting
Prevention
You should always have at least two people working together if
the engine must be run during service. One person needs to
remain in the operator's seat, ready to work the controls or stop
the machine and shut off the engine.
Unless you are instructed otherwise, never attempt adjustments
while the machine is moving or while the engine is running.
Stay clear of all rotating parts and moving parts.
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 the 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 Adjustments Require
Caution
Never turn out the track tension grease fitting nut. To release
pressure from the crawler frame track tension assembly, you
should NEVER attempt to disassemble the track adjuster or
attempt to remove the 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 Blocking 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.
