CAUTION
It is very important to keep the hydraulic supply
system clean at all times. Be sure that all hydraulic
fluid lines are absolutely clean at all times. Blow out
the lines with air and flush thoroughly with solvent
before connecting to the hydraulic motor, to avoid
introducing harmful contaminants into the motor.
Plug the hydraulic lines immediately when they are
disconnected.
Do not exceed 37.8 liter/min (10 gpm) hydraulic oil
volume to the motor, to avoid pump stalling.
For optimum pump performance, keep the tempera-
ture of the hydraulic oil below 54_ C (130_ F)
