Operating Procedures - DeWalt DWMT70779 Instruction Manual

OPERATING PROCEDURES

WARNING: Do not attempt to unclog (back flush) the spray gun
by squeezing the trigger while holding your finger in front of
the fluid nozzle.
CAUTION: Pressure may vary according to viscosity of material
used. Maximum working pressure of the gun is 40 PSI. Do not
exceed pressure limit of gun or any other component in system!
CAUTION: Prior to daily operation, make certain that all
connections and fittings are secure. Check hose and all
connections for a weak or worn condition that could render system
unsafe. All replacement components such as hose or fittings must
have a working pressure equal to or greater than system pressure.
SIPHON FEED USE:
1. Mix material according to the manufacturer's instructions.
Mixture should be smooth and easily pourable. Lumps or
foreign particles should be removed by straining through
a suitable paint filter.
noTe: When applying heavy bodied paints, the internal Mix Air
Cap included is recommended.
noTe: If not using the siphon feed setting, see "Internal Pressure
Feed" or "Remote Pressure Feed' paragraphs.
2. Fill the material cup (e) ¾" full.
3. Attach material cup (e) to the gun securely.
4. Attach air supply line to the ¼" air inlet (G).
5. To adjust the spray pattern, loosen the air cap (a) and rotate
the horns (B) to achieve desired pattern. Then tighten
air cap (a).
6. Turn the fluid control knob (J) clockwise until it stops, do
not force it. This will shut off the fluid flow.
7. Adjust air pressure to 40 PSI at air compressor
WARNING: DO NOT exceed 100 PSI.
8. Turn the air volume control knob (h) counterclockwise until
the first thread is flush with the gun body.
WARNING: DO NOT turn air valve control knob the or fluid
control knob out until first thread is past the gun body. They are
under pressure when the gun is triggered and could leave the gun
with force.
noTe: Care should be exercised when handling spray gun to
avoid damage to the orifice of the air cap and tip of fluid nozzle.
Damage to these parts results in irregular spray patterns.
9. Depress spray gun trigger (F) and gradually turn the
fluid control knob (J) counterclockwise until desired fluid flow
is reached. Trigger gun quickly, one second on-off to test pattern.
WARNING: NEVER point spray gun at self or any other person.
Accidental discharge of material may result in serious injury.
noTe: If gun sprays too fast, decrease the air and fluid pressure.
If too slow, increase the pressure. Turn fluid control knob (J)
counterclockwise to increase, or clockwise to decrease, the fluid
flow. Turn air volume control knob (h) counterclockwise to
increase, or clockwise to decrease, the air flow.
noTe: When using the internal mix air cap, begin with the same
air and fluid pressure.
