Operation
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
Whenever you stop spraying for a moment, engage
the gun safety latch. See Fig. 2.
WARNING
The wallet-size warning card provided with this gun
should be kept with the operator at all times. The
card contains important treatment information
should an injection injury occur. Additional cards
are available at no charge from Graco Inc.
1. Start the pump. Adjust the fluid pressure so the
spray is completely atomized. ALways use the
lowest pressure necessary to get the desired
results. Higher pressure may not improve the
spray pattern and will cause premature tip and
pump wear.
2. If adjusting the pressure does not give a good
spray pattern, try another tip size. Relieve the
pressure completely before changing tips.
3. 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. Do not swing the gun in an
arc. Practice to find the best length and speed of
stroke.
How to use the Safety Knob (Fig. 2)
To engage the safety knob, turn the knob fully clock-
wise which locks the needle in the forward position,
making the valve inoperative. Failure to engage the
safety knob when you are not dispensing may result in
accidental triggering of the valve.
To disengage the safety knob, turn the knob fully
counterclockwise.
