GENERAL DESCRIPTION

The 10" air motor is a power unit used with a two-ball or
chop-check pump. It utilizes tie rod construction for easy
breakdown and it connects to the lower pump end with tie
rods for easy operation. Consult the pump model operator's
manual for specifi c instructions.
OPERATING AND SAFETY PRECAUTIONS
DO NOT EXCEED MAXIMUM AIR INLET PRESSURE OF 90
P.S.I. (6.2 bar) OR 75 CYCLES PER MINUTE.
CAUTION: High pressure equipment - Always disconnect air
supply and relieve material pressure before attempting to
service.
A ground lug is located on the air motor. This ground lug al-
lows proper grounding of the pump.
AIR AND LUBE REQUIREMENTS
A filter capable of filtering particles larger than 50 microns
should be used with a lubricator.
Filtered and oiled air will allow the pump to operate more ef-
fi ciently and yield a longer life to operating parts and mecha-
nisms.
Use an air line lubricator and keep it supplied with a good
grade of S.A.E. #90W non-detergent gear oil set at a rate not
to exceed approximately 1 drop per minute.
