PRIMING

Preparing to Prime

1. Before priming, squirt some hydraulic oil (P/N 0154908
included with unit) into the indicated area. Light
household oil can be substituted if necessary. This will
prolong seal life of the unit.
NOTE: Apply only a teaspoon amount at a time. Too
much oil may cause the oil to drip into the paint.

Purging and Priming

If this unit is new, it is shipped with test fluid in the fluid section
to prevent corrosion during shipment and storage. If you are
going to spray latex paint, this fluid must be purged and
thoroughly cleaned out of the system. If you are going to
spray with solvent-based paint, this fluid must be purged from
the system, but thorough cleaning is not necessary.
If the pump has already been used you will need to purge the
water or solvent used in cleanup and storage.
WARNING
Always keep the spray gun locked off when purging the pump.
Purging and Priming the Pump for Latex Paint
1. Secure the return tube into a
waste container.
2. Place a full container of paint
underneath the suction tube.
3. Turn the pressure control dial
to minumum pressure (-).
4. Turn the PRIME/SPRAY knob to PRIME.
5. Move the ON/OFF switch to the ON position. If unit does
not start, turn pressure control dial one to two turns until
unit turns on.
6. The unit will begin to draw paint up the suction tube, into
the pump, and out the return tube. Let the unit cycle long
enough to remove test fluid from the pump, or until paint is
coming from the return tube.
7. Remove the return tube from the
waste container and place it in its
operating position above the
container of paint.
8. Keep circulating the paint through the
system until the paint coming out of
the return tube is free of air bubbles.
9. Move the ON/OFF switch to the OFF position.
The pump is now purged. Skip to Purging and Priming the
Spray Hose.
Purging and Priming the Spray Hose
After the pump is purged and primed, you must do the same
for the spray hose.
1. Lock the spray gun off.
2. Remove the spray tip from the gun.
3. Turn the PRIME/SPRAY knob to
SPRAY.
4. Be certain that the spray gun is
unlocked and trigger it into a
waste container. Hold the trigger
