WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
See Parts illustration for referenced items. Shut off the
air supply to the pump and relieve the pressure.
Check the air line lubricator often and keep it filled with
oil. Also check the pump packing nut regularly to keep
it just tight enough to stop leakage, but no tighter. Use
a 1/4 in. (6.3 mm) diameter rod to tighten.
To manually lubricate the motor, disconnect the air line
at the motor and place 10 to 15 drops of oil in the inlet.
Reconnect the air line and turn on the air to blow oil
into the motor. Shut off the air supply to the pump and
relieve the pressure.
Proper packing nut take-up will stop leakage. However,
all the packings should be replaced after 1000 hours
of operation or delivery of 120,000 gallons of solution
at 2 gpm. Refer to separate pump manual.
Clean the air line filter regularly.
Remove the inlet filter (2) daily and clean it. Check it
for damage that may allow contaminants to enter the
pump, and replace if necessary.
Refer to the separate instruction manuals supplied with
the components of your system for complete trouble-
shooting and service instructions.
