Priming the Pump
1
. Turn the pressure control knob counterclockwise to its
l
owest pressure setting.
2. Remove the paint hopper cover and fill the paint hopper
with material.
3. Turn the PRIME/SPRAY knob to PRIME.
4. Turn the motor switch to ON.
5. Turn the pressure control knob clockwise to between half
and full pressure. Let the unit prime 1 to 2 minutes after
material begins to flow through the return tube.
Always reduce the pressure to zero before changing the
position of the PRIME/SPRAY knob. Failure to do so may
cause damage to the paint pump diaphragm.
If the pressure control knob is reduced to zero and the
PRIME/SPRAY knob is still on SPRAY while the sprayer is
operating, there will be high pressure in the hose and
spray gun until the PRIME/SPRA
Y
knob is turned to PRIME
or until the spray gun is triggered to relieve the pressure.
