Hydraulic Pump
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
Tip-over hazard. After replacing
the hydraulic pump, it is critical to
return the function speed
settings to original factory
specifications. Failure to restore
the machine to original factory
specifications could cause the
machine to tip over resulting in
death or serious injury.
