WARNING
FUEL HAZARD
The fuel used in this equipment is flammable. When spilled on a hot surface it can ignite and cause a
fire. Do not fill fuel tank while engine is running or hot.
INJECTION HAZARD
Spray from gun, leaks or ruptured components can inject fluid into your body and cause an extremely
serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also
cause serious injury.
DFluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi-
cal attention.
DDo not point gun at anyone or any part of the body.
DDo not put hand or fingers over the spray tip, and do not stop or deflect fluid leaks with your hand,
body, glove or rag.
DDo not “blow back” fluid; this is not an air spray system.
DAlways have tip guard and trigger guard on gun when spraying.
DEngage trigger safety whenever you stop spraying.
DFollow the Pressure Relief Procedure on page 4 when you are instructed to relieve pressure;
stop spraying; check, clean, or service any system equipment; or install or change spray tips.
DTighten all fluid connections before each use.
DCheck the hoses, tubes and couplings daily. Replace worn or damaged parts immediately. Perma-
nently coupled hoses cannot be repaired.
DHandle and route hoses and tubes carefully. Keep hoses and tubes away from moving parts and
hot surfaces. Do not use the hoses to pull equipment. Do not expose ASM hoses to temperatures
above 150_F (65_C) or below –40_F (–40_C).
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the
skin, inhaled, or swallowed.
To help prevent injury or death from toxic fluids
DKnow specific hazards of fluid you are using; store hazardous fluid in approved tub; dispose of
hazardous fluid according to all local, state, and national guidelines.
DAlways wear protective eyewear, gloves, clothing, and respirator as recommended by fluid and
solvent manufacturer.
FLUID SPLASHBACK HAZARD
To avoid splashback of fluid while spraying, make sure the spray gun is assembled with the correct
gasket for the fluid being sprayed.
EXHAUST HAZARD
The exhaust contains poisonous carbon monoxide which is colorless and odorless. Do not operate
this equipment in a closed building.

Pressure Relief
Follow these instructions whenever you are instructed to relieve pressure,
stop spraying for more than 10 minutes, check or service the equipment,
or install or clean the spray nozzle.
1. Engage trigger safety latch.
2. Turn Pressure Washer off and remove ignition cable
from spark plug.
3. Shut off water supply. Disconnect from water.
4. Remove trigger safety latch and trigger gun to
relieve pressure. Then engage the safety latch.
Note: If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after
following this procedure, disengage trigger safety latch and trigger gun again.
