Operation

Starting and Operating the Pump

WARNING

To reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin, and property
damage, never exceed the maximum air and fluid
working pressures of the lowest rated component
in your system. Refer to the 

Equipment Misuse

Hazard

 on page 2.

1.

Mount the pump and connect to a fluid supply as
explained in 

Installation

 on pages 4–6.

2.

See the 

Installation

 on page 4. Be sure the air

regulator (A) and bleed–type master air valve (D)
are closed.

3.

Hold a metal part of the spray gun/dispensing
valve firmly to the side of a grounded metal pail
and hold the trigger open. Then open the pump’s
bleed–type master air valve (D). Now slowly open
the air regulator (A) until the pump starts.

4.

Run the pump slowly until all the air is pushed out
of the pump and hose. Always use the lowest
pressure necessary to get the desired results.
Higher pressures waste fluid and cause premature
system wear.

5.

After all the air is purged, release the gun/dispens-
ing valve trigger. This pump will not stall on either
stroke. It will continue to creep until the air supply
is shut off.

Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. If your pump acceler-
ates quickly, or is running too fast, stop it immediately
and check the fluid supply. If the supply container is
empty and air has been pumped into the lines, refill the
container and prime the pump and the lines with fluid,
or flush and leave it filled with a compatible solvent. Be
sure to eliminate all air from the fluid system.

Shutdown and Care of the Pump

For overnight shutdown, flush the pump and follow the

Pressure Relief Procedure

 at left . Always stop the

pump at the bottom of its stroke. Doing so helps
prevent damage to the throat packings caused by
buildup of dried fluid on the upper piston rod and
corrosion of the rod due to moisture.

NOTE:

The pump is at the bottom of its stroke when

the air motor exhausts.

CAUTION

Water, even moist air, can cause your pump to
corrode. To help prevent corrosion, NEVER leave the
pump filled with water or air. After normal flushing,
flush the pump again with mineral spirits or oil–based
solvent, relieve pressure, and leave the mineral
spirits in the pump. Be sure to follow the 

Pressure

Relief Procedure

 at left.

Lubrication

If you are not using an accessory air line lubricator,
manually lubricate the motor daily. Disconnect the air
regulator, place about 15 drops of light machine oil in
the pump air inlet, reconnect the regulator, and turn on
the air supply to blow air into the motor.
