of output and control of speed, use air line of not less then 1/2" pipe size. When coupling or
connecting the motor to a drive member, avoid any end or side thrust on the output shaft and
especially DO NOT HAMMER ON SHAFT.
The starting torque is more than the running torque and could vary depending on the position
at which the vanes stop in relation to the air intake port. The speed and torque can be regulated
by using a pressure regulator or a sim ple shut-off valve. Lubrication is necessary for the shaft
seal, and rust prevention. Each air powered pump is equipped with an automatic air line oiler set
to feed 1-3 drops per minute. Use The manufacturer Inc. antifreeze oil. Excessive mois ture in
the line can cause rust formation in the motor and might also cause ice to form in muffler due to
expansion of air through the motor.
NOTE: To adjust oiler drops, turn dial counter clockwise to "raise", and clockwise to "lower".
If the motor is sluggish or inefficient, try flushing with solvent in well ventilated area.
Disconnect the air line, again connect the air line and apply pressure slowly until there is no
trace of solvent in exhaust air. (Keep face away from exhaust air.) Check the muffler felts
for grease, dirt, etc. If dirty, wash them in solvent. Replace the felts and connect muffler.
Relubricate the motor with a squirt of oil in the chamber. If the vanes need replacing, or foreign
particles are present in motor chamber, an experi-enced mechanic may remove the end plate
apposite the drive shaft end.
WARNING
To prevent explosive hazard, do not pump combustible liquids or vapors through these units.
AFTER COMPLETING THE JOB
Before disconnecting hoses, fittings, etc. first be sure the tool is unloaded and retracted, then
disconnect the air line and shift the hydraulic controls several times to release system pressure.
Store the pump in a clean, dry area.
MAINTAIN OIL LEVEL
Check hydraulic oil level every 30 hours of operation (sight gauge should be completely
covered in oil when all tools are retracted. Add the manufacturer oil (1 gallon) when necessary.
Oil level should be no more than 1" from top of reservoir plate – with cylinders retracted and
motor off.
PERIODIC MAINTENANCE
Completely change the hydraulic oil and clean the intake screen and magnet (located in
the reservoir) twice a year. If equipped, change the external oil filter twice a year (Use The
manufacturer oil only, Model # AO1, 1 gallon). Change the oil more frequently when used
in extremely dusty areas or when the oil has been overheated. Using oil other than The
manufacturer Brand may void the pump's warranty.
