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

rettes, 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.

Do not use 1,1,1-trichloroethane, methylene chlo-
ride, other halogenated hydrocarbon solvents or flu-
