 For the application of architectural paints and coatings -

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 hazard symbols refer to procedure-specific risks. Refer back to these 
Warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.

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 servic-
ing 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, cig-

arettes, 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 Ground-

ing instructions.

• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when trigger-

ing 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 compo-
nent. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equip-

ment wetted parts. See Technical Data in all equip-
ment manuals. Read fluid and solvent manufacturer’s 
warnings. For complete information about your mate-
rial, 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.

PRESSURIZED ALUMINUM PARTS HAZARD 
Do not use 1,1,1-trichloroethane, methylene chloride, 
other halogenated hydrocarbon solvents or fluids con-

taining such solvents in pressurized aluminum equipment. Such 
use can cause serious chemical reaction and equipment rup-
ture, and result in death, serious injury, and property damage. 

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 and hearing protection

Gloves, clothing and respirator as recommended by the
