The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation 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.

WARNING
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.
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.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause a serious chemical reation and
equipment rupture. Failure to follow this warning may result in death, serious injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents.
• Many other fluids may contain materials that are incompatible with aluminum. Contact your material supplier for
verification.

WARNING
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 component. 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 manufacturer’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.

PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or in the operating area of the equipment to help protect you from serious injury. This equipment includes but is not limited to:
• Protective eyewear, gloves, hearing protection
• Clothing and respirator as recommended by the fluid and solvent manufacturer

Pressure Relief Procedure

Setup
Make sure sprayer is turned off and unplugged
from power source. Refer to your sprayer
manual for priming and spray instructions.

Follow this Pressure Relief Procedure whenever instructed
to relieve pressure, stop spraying, check or service equipment,
or install or clean spray tip.
1.
2.

Turn OFF power and turn sprayer pressure control to lowest pressure setting.
Hold gun against side of flushing pail. Trigger gun into pail
to relieve pressure.

If you suspect spray tip or hose is clogged or that pressure has
not been fully relieved after following 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.

Gun Trigger Lock (2)
To prevent injury when the gun is not in use,
always set the gun’s trigger lock (2) if unit is
being shut down or left unattended.
