Operation
WARNING
D
This pump is designed to be used ONLY in
pumping non-corrosive and non-abrasive lubri-
cants and greases. Any other use of this pump
can cause unsafe operating conditions and
result in component rupture, fire, or explosion,
which can can cause serious bodily injury,
including injection.
D
Moving parts can pinch or amputate your fin-
gers or other body parts. When the pump is
operating, the priming piston (located at the
pump intake) and the air motor piston (located
behind the air motor plates) move. NEVER
Operate the pump with the air motor plates
removed, and keep your fingers and hands
away from the priming piston.
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause
serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving
parts, follow the
Pressure Relief Procedure
whenever you
D
Are instructed to relieve the pressure
D
Stop dispensing
D
Check or service any of the system equipment
D
Install or clean the dispensing nozzles
1.
Close the air regulators.
2.
Close the supply pump’s bleed-type master air
valve (required in this system).
3.
Open the dispensing valve until pressure is fully
relieved.
If you suspect that the dispensing valve, extension, or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after following the steps above,
VERY SLOWLY loosen the coupler or hose end
coupling and relieve pressure gradually, then loosen
completely, then clear the clog.
Startup and Adjustment
Open the bleed-type master air valve. Open the
dispensing valve, and slowly open the air regulator
until the pump is running smoothly. After all the air is
purged, close the dispensing valve. The pump will
start and stop as the valve is opened and closed.
CAUTION
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed and may damage 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, prime
the pump and lines with fluid, or flush the pump and
leave it filled with a compatible solvent. Be sure to
eliminate all air from the fluid system.
Use the air regulator (E) to control the pump speed
and fluid pressure. See Fig. 2. Always use the lowest
pressure necessary to obtain the desired results.
When you are finished using the pump for the day,
always follow the
Pressure Relief Procedure
at left.
Maintenance
The Accessory air line oiler (D) provides automatic air
motor lubrication. For daily manual lubrication,
disconnect the air hose, place about 15 drops of light
machine oil in the air inlet, reconnect the hose, and
turn on the air supply to blow oil into the motor.
