DANGER
Rotating Drive Shaft Hazard!
The crawler drive shaft rotates at high speed. Death or
serious injury will occur if body parts or clothing come in
contact with a rotating drive shaft.
To prevent death or serious injury:
• Make sure the drive shaft is securely attached at both
ends.
• Make sure the guards are in place and securely
attached at both ends during operation.
• Do not attempt to service the drive shaft until the
crane has been parked and the engine stopped.
