Prevention of Crushing and Cutting 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 fraved. 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 Adjustments Require 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.
