Installation/Operation
How to Operate the Gun
WARNING
RECOIL HAZARD
Due to the very high pressure, a strong
recoil action will occur when you trigger
the gun. If you are unprepared, your
hand could be forced back toward your body or you
could lose your balance and fall, resulting in seri-
ous injury.
WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
including injection:
D Do not exceed the maximum working pressure
of the gun or the lowest rated component in the
system.
D Follow the Pressure Relief Procedure on page
7 whenever you are instructed to relieve the
pressure.

NOTE: Strain the fluid you are spraying if it contains
particles which could clog the spray tip.
1. Connect a grounded fluid hose (A) to the gun inlet.
See Fig. 2.
2. With no tip installed, start the pump. Flush the
pump according to the instructions supplied with it.
Use the lowest pressure possible. Be sure you
have a firm footing and hold the gun securely.
Prime the system with the material.
3. Relieve the pressure.
4. Install the SwitchTip (8) and tip guard (30). Follow
the instructions in the manual, supplied. See
Fig. 2.
5. Start the pump. Trigger the gun onto test paper.
Adjust the fluid pressure until the spray is
completely atomized. Use the lowest pressure
necessary to get the desired results. Higher pres-
sure may not improve the spray pattern and will
cause premature tip and pump wear.
6. If adjusting the pressure does not give a good
spray pattern, relieve pressure and then try
another tip size.
7. Use a full-open, full-close trigger action. Hold the
gun about 14 in. (350 mm) from and at right angles
to the work surface. Don’t swing the gun in an arc.
Practice to find the best length and speed of
stroke.
How to Adjust the Spray Pattern
1. To adjust the spray pattern direction, relieve pres-
sure. Loosen the tip guard retaining nut (B). Turn
the tip guard/tip groove horizontally (C) for a
horizontal pattern and vertically (A) for a vertical
pattern. Tighten the nut. See Fig. 3.
2. The spray tip orifice and spray angle determines
the coverage and size of pattern. When more
coverage is needed, use a larger spray tip rather
than increasing fluid pressure.
CAUTION
Openings in the tip guard reduce paint buildup on the
guard while spraying. Damage to the sharp edges of
the openings causes paint to collect at that area.
Never hang the gun by the tip guard.
