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.

3. Unlock the gun and squeeze the trigger, pointing the gun at
a scrap piece of wood or cardboard. This allows pressure in
thesprayhosetoblowouttheobstruction.Whenthenozzle
is clean, material will come out in a straight, high pressure
stream.
4. Release the trigger and lock the gun off. Reverse the tip so
the arrow points forward again. Unlock the gun and resume
spraying.
Cleanup
i
If you are using water-soluble materials, use warm suds
to clean the spray device. If you are using solvent-
based spray, use a suitable solvent for cleaning, with a
flash point of over 21°C.
i
Do not use solvents for water-soluble materials, as the
mixture will turn into a gel-type substance which is
difficult to remove.

i
Only follow these instructions when using water-
soluble materials. If you are using solvent-based spray,
follow the Cleanup and Long-Term Storage steps.
