Warnings
312796S 3
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are
present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until
you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-
ponent. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about
your material, request MSDS forms from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufac-
turer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a
cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.

See FIG. 2. Verify that the ground screw (GS) is attached
and tightened securely to the air motor. Connect the
other end of the ground wire (U) to a true earth ground.
Accessories
Bleed-type master air valve
• Required in your system to relieve air trapped
between it and the air motor when the valve is
closed.
• Be sure the valve is easily accessible from the pump
and located downstream from the air regulator.
Air regulator
Adjusts air pressure to the motor and fluid outlet pres-
sure of pump. Locate it close to the pump. Install a
gauge to read air pressure.
Air filter
Removes harmful dirt and moisture from compressed
air supply.
FIG. 2: Ground wire

Preventive Maintenance
Schedule
The operating conditions of your system determine how
often maintenance is required. Establish a preventive
maintenance schedule by recording when and what kind
of maintenance is needed, and then determine a regular
schedule for checking your system.
Pressure Relief Procedure
1. Engage the trigger lock.
2. Close the bleed-type master valve.
3. Disengage the trigger lock.
4. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure.
5. Engage the trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to spray
again.
7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after follow-
ing the steps above, VERY SLOWLY loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.
Repair Air Valve
Replace Complete Air Valve
1. Stop the pump at the middle of its stroke. Relieve
the pressure. See procedure at left.
2. Disconnect the air line to the motor.
3. For motors with DataTrak: Remove screw (32) to
disconnect the reed switch (31) from the air valve
(17).
4. For motors with DataTrak: If equipped with a run-
away protection solenoid, remove two screws (18)
and the solenoid bracket (26). Pull the solenoid (25)
out of the air valve.
• Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from skin
injection or moving parts.
• Do not lift or move motor while pressurized.

fold, then attach the air valve (17).
8. For motors with DataTrak: If equipped with a run-
away protection solenoid, remember to reattach the
solenoid bracket and the solenoid.
9. For motors with DataTrak: Use screw to attach the
reed switch assembly to the new air valve. Be sure
the sensor cables are connected properly (see
