WARNING
Do not allow hydraulic fluid or cleaning solvent to come in contact with unprotected
skin or eyes. Prolonged skin contact can cause illness or injury. Eye contact can cause
serious injury. Always wear chemical protective gloves and goggles when handling
used hydraulic fluid and cleaning solvent. Failure to comply can result in illness, seri-
ous injury, or death.
Hydraulic hoses and lines may be under pressure. Relieve pressure by operating the
appropriate control valve if possible. Loosen fittings on hose lines slowly. Allow oil to
run around threads of fitting, releasing pressure before disconnecting fitting. Releasing
pressurized oil suddenly can cause serious injury or death.

Don chemical protective gloves and goggles.

Cotter pins, lockwashers, locking nuts, and similar locking devices shall be discarded after removal and replaced with
new cotter pins, lockwashers, locking nuts and similar locking devices.
