The 4-1/4" air motor is a general purpose power unit and
is used with many 2-ball, 4-ball and chop check pumps. It
utilizes tie rod type construction for easy breakdown and
it connects to the various lower ends via tie rods for easy
operation. Consult pump model operator's manual for
specifi c instructions. It is recommended that a muffl er be
connected to the exhaust port to reduce noise to accept-
able OSHA standards.
Filtered and oiled air will allow the air motor to operate
more effi ciently and yield a longer life to operating parts
and mechanisms. A filter capable of filtering particles
larger than 50 microns should be used with an oiler. Keep
the oiler supplied with a good grade of S.A.E. no. 90W
non-detergent gear oil, set at a rate not to exceed 1 or 2
drops per minute.
NOTICE: Do not operate the air motor above the recom-
mended air pressure of 150 p.s.i. (10.3 bar) or 75 cycles
per minute. The air motor may be rated diff erently in the
next assembly. Check the pump model plate.

MAINTENANCE
The air / hydraulic motor is completely separate from the
lower pump end. This helps to keep the motor from being
contaminated by the material being pumped. Periodically,
fl ush entire pump system with a solvent that is compatible
with the material being pumped.
Keep solvent cup fi lled with this compatible solvent. This will
keep material from drying on the piston rod, which would
drag thru the packings, ruin them and eventually scour the
piston rod.
Provide a clean work surface to protect sensitive internal
moving parts from contamination from dirt and foreign mat-
ter during disassembly and reassembly.
Before reassembling, lubricate parts as required. When as-
sembling "O" rings, or parts adjacent to "O" rings, exercise
care to prevent damage to "O" rings and "O" ring groove sur-
face.
