To reduce the risk of serious bodily injury, including
fluid injection or splashing in the eyes or on the
skin, always follow the Pressure Relief Proce-
dure on page 2 before checking, servicing, remov-
ing, changing or cleaning spray tips or any part of
the gun or system.
Whenever you stop spraying for a moment, en-
gage the gun safety latch. See Fig 2.
WARNING
WARNING
The wallet-sized 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 from Graco Inc. at no charge.
1.
Start the pump. Adjust the fluid pressure so the spray
is completely atomized. Always use the lowest pres-
sure 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 pressure com-
pletely before changing tips.
3.
For maximum seat and needle life, Use a full-open,
full-close trigger action. Hold the gun about 14 in.
(350 mm) from and at right angles to the work sur-
face. Don’t swing the gun in an arc. Practice to find
the best length and speed of stroke.
Adjust the spray pattern
1.
To adjust the spray pattern direction, first relieve
pressure. Be sure the trigger safety latch is engaged.
Loosen the tip guard retaining nut. Turn the tip guard
so it is vertical for vertical pattern and horizontal for
a horizontal pattern. Tighten the retaining nut. See
Fig 3.
2.
The spray tip orifice size and spray angle determines
the coverage and size of pattern. When more cover-
age is needed, use a larger spray tip rather than in-
creasing the fluid pressure.
WARNING
To reduce the risk of a fluid injection injury, NEVER
use the gun with the tip guard or trigger safety
removed.
Openings in the tip guard are designed to reduce
paint buildup on the guard when spraying. Any
damage to the sharp edges of the openings causes
paint to collect at that area. To reduce the risk of
damage, never hang the gun by the tip guard. See
Fig 3.
