hose between the main hose and the gun.
CAUTION
To avoid damaging the pressure control, which may
result in poor equipment performance and component damage, follow these precautions:
1. Always use grounded, flexible spray hose at
least 50 ft. (15 m) long.
2. Never use a wire braid hose as it is too rigid to act
as a pulsation dampener.
3. Never install any shutoff device between the filter
and the main hose. See Fig. 2.
4. Always use the main filter outlet for one gun operation. Never plug this outlet.
WARNING
FIRE AND EXPLOSION HAZARD
Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Read the warning section FIRE OR EXPLOSION HAZARD on
page 2 for more detailed grounding
instructions.
4. Check the Electrical Service.

start it safely.
WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
follow the illustrated Pressure Relief
Procedure warning on page 12 when-
ever you are instructed to relieve pressure.
NOTE: Flush the sprayer if this is a first-time startup.
See page 11.
NOTE: See Fig. 4 except where noted.
1. Put the suction tube into the paint container .
2. Turn the pressure adjusting knob fully coun-
terclockwise to zero pressure.
3. Plug in the sprayer.
CAUTION
c. Release the trigger. Engage the gun safety latch.
5. Check all fluid connections for leaks . Relieve
the fluid pressure before tightening connections.
6. Install the spray tip and tip guard. Engage the
gun safety latch. See Fig. 3. Install the spray tip
according to the instructions supplied with it.
7. Adjust the spray pattern.
a. Increase the pressure just until spray from the
gun is completely atomized. Use the lowest
pressure needed to get the desired results. This
reduces overspray and fogging, decreases tip
wear and extends the life of the sprayer.
b. If more coverage is needed, use a larger tip
rather than increasing the pressure.
c. Test the spray pattern. T o adjust the pattern,
engage the gun safety latch, loosen the retaining
nut. Position the tip guard horizontally for a horizontal pattern or vertically for a vertical pattern.
Then tighten the retaining nut.
