NOTE: Always adjust the fluid pressure to the lowest
pressure needed. This maximizes the efficiency of the
gun adjustments.
When spraying small, confined areas, the valve and
knob may be used to make fine adjustments without
adjusting the pump when spraying smaller, confined
areas, such as closets.
Material flow knob adjustment
(Fig. 2)
For a lighter spray pattern, turn IN the knob (18).
For a heavier spray pattern, turn OUT the knob (18) so
that no more than two threads are showing.
CAUTION
Turning the knob (18) out too far will remove the
knob and the gun will not shut off when the trigger is
released.
Air flow valve adjustment
(See Fig 2)
To decrease air flow turn the air valve (23) toward –.
To increase air flow, turn the air valve (23) toward +.
Check and thin the material as needed to maintain the
proper consistency. The material may thicken as it sits
and slow down production or affect the spray
pattern.
Flush the gun at the end of each work day and dry it.
Oil the gun daily with a few drops of light oil (SAE–10)
at the points indicated in Fig. 2.
