Purging and Priming the Sprayer
All new units are performance-tested at the factory and are shipped with test fluid in the fluid section to prevent corrosion during shipment and storage. If you
have already used your pump, some water or solvent used in cleaning may remain in the fluid section. Whether your sprayer is new or if you have already used
it, this fluid must be purged and thoroughly cleaned out of the system prior to use. Follow the steps below.
1. Place a full container of spraying material under-
neath the suction tube (a). Secure the return tube (b)
into a waste container.
2. Turn the pressure control dial to maximum pressure.
Turn the PRIME/SPRAY knob to PRIME.
3. Plug in the sprayer and move the ON/OFF switch to
the ON (l) position.
4. Switch the pump OFF (O). Remove the return tube
from the waste container and place it in its operating po -
sition above the container of spraying material. Use the
metal
The unit will begin to draw material 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 spray material is coming from the re -
turn tube.
Purging and Priming the Spray Hose
1. Unlock the spray gun and turn the PRIME/SPRAY
knob to PRIME.
The spray tip SHOULD NOT be attached to your
spray gun when purging your spray hose.
2. PULL the trigger and aim the spray gun at the side wall of a
waste container. If using oil-based materials, the spray gun must
be grounded while purging (see warning below).
Keep hands clear from fluid stream. Ground the gun by holding it
against the edge of a metal container while flushing. Failure to do
so may lead to a static electric discharge which may cause a fire.
3. While pulling the trigger, switch the pump ON (l), AND turn the PRIME/SPRAY knob to SPRAY. Hold the trigger until all air,
water, or solvent is purged from the spray hose and material is flowing freely.
If the PRIME/SPRAY knob is still on SPRAY,there will be high pressure in the hose and spray gun until the PRIME/SPRAY knob is
turned to PRIME.
