998HVLP Siphon Feed Spray Gun:
1. The spray gun should be lubricated frequently, using a
non-silicone oil. Place a drop on all moving parts, as
shown in illustration.
2. Do not completely disassemble the spray gun if poor
spray pattern occurs. See trouble shooting guide for
information on how to correct this problem.
3. Never submerge complete spray gun in any cleaning
solution.
4. Never use any hard objects, such as wire, paper clip, or
welding tip cleaner to clean the air cap orifices.
The air cap is made of high alloy heat treated aluminum
and hard objects will damage the orifices. To clean the
air cap, soak it in a compatible cleaning solution and use soft objects, such as a medium bristle brush.
5. Gun can be cleaned in gun washer.
450T -Lined "No-Drip" Cup Assembly:
1. cup assembly may be cleaned with compatible solvents by hand or in gun washer.

HVLP SYSTEM SPRAY GUN MAINTENANCE:
SPRAYING OPERATION:
WARNING: Never pull trigger on spray gun when pointed in the direction of face, eyes or body.
To ensure optimum performance and compliance with applicable HVLP regulations, the following set-up
procedure is necessary:
1. The Model 998HVLP Series spray gun requires an air supply of 13.9 CFM. This would normally be
supplied by a minimum 4 hp compressor in good working condition. In addition, the air hose leading to
the gun should be at least 3/8" (inside diameter) also in good condition.
2. Insure that no air restrictions such as low-volume cheater-valves impede the air flow to the HVLP
System. If an air adjusting valve is desired, use a SHARPE 24AAV (Comp. # 2210) Air Adjusting Valve.
3. After supplying adequate air to the gun, adjust the inlet pressure to the lowest level recommended by
your paint manufacturer (usually 30-50 PSI). This will give you the best transfer efficiency and also
optimize your paint savings. The gun will automatically reduce the spraying pressure to 10 PSI or less
at the air cap.
4. The 998HVLP Series spray guns are designed to function at inlet pressure less than 40 PSI.
If you exceed 40 PSI inlet pressure, the pattern may distort and you may also exceed some HVLP
compliance regulations.
5. Once desired atomization is achieved, pattern size and shape is determined by adjusting the spray width
adjuster knob (top knob on spray gun handle). Turn knob clockwise to reduce pattern size, turn knob
counter-clockwise to increase pattern size. NOTE: See enclosed trouble shooting guide if you experience
an irregular pattern.
