Spraying Troubleshooting -

Unclogging the Spray Tip

Do not attempt to unclog or clean the tip with
your finger.
NOTE - Do not use a needle or other sharp pointed
instrument to clean the tip. The hard tungsten
carbide can chip.
If the spray pattern becomes distorted or stops completely
while the gun is triggered, follow these steps.
1. Release the trigger and lock
the gun off (see page 5).
Rotate the reversible tip
arrow 180º so that the point
of the arrow is toward the
rear of the gun (CLEAN
position).
Under pressure, the spray tip may be very difficult to turn.
Turn the PRIME/SPRAY knob to PRIME and trigger the gun.
This will relieve pressure and the tip will turn more easily.
2. Turn the PRIME/SPRAY knob to SPRAY.
3. Unlock the gun and squeeze the trigger, pointing the gun
at a scrap piece of wood or cardboard. This allows
pressure in the spray hose to blow out the obstruction.
When the nozzle is clean, material will come out in a
straight, high pressure stream.
SPRAY
PRIME
If material still will not spray from the spray tip, follow the
steps in the next column.
4. Release the trigger and lock
the gun off (see page 5).
Reverse the tip so the arrow
points forward again (SPRAY
position). Unlock the gun
and resume spraying.

Follow these steps if your spray pattern
becomes distored or stops completely.
