well as hose whipping.
Avoid sharp objects. Keep hose away from sharp objects. Bursting hoses may
cause injury.
No load bearing. Do not use the pump to support other items of equipment that
impose unacceptable loads on the pump. Do not attempt to use this machine as a
prop.
Lock trigger safety latch when not spraying. Spray gun is equipped with a built-
in trigger safety latch to guard against accidental trigger release. Rotate safety
latch to the locked position when not spraying.
Leaving unattended. Always turn off the pressure washer and relieve system
pressure before leaving the sprayer unattended.
Prompt Emergency Response
Seek medical aid for suspected injection injury. If injured by high-pressure
fluid, no matter how small the wound is, see a doctor at once. A typical injection
injury may be a small puncture wound that does not look serious. However,
severe infection or reaction can result if proper medical treatment is not
administered immediately by a doctor who is familiar with injection injuries.
Seek medical aid for suspected carbon monoxide poisoning. The running
engine gives off carbon monoxide, a poisonous gas that can kill you. If you start
to feel sick, dizzy, or weak while using the pressure washer, shut off the engine
and get to fresh air RIGHT AWAY. See a doctor. You may have carbon
monoxide poisoning.
Put on personal
protective gear WARNING:
Use personal protective gear to prevent:
- Eye and skin injection injury from high pressure spray
- Burns from hot water or steam
- Eye injury from flying debris
1. Wear waterproof, thermally insulated gloves, safety glasses with side
and top protection, face protection, and protective clothing when
operating the machine. If spraying pressure washer specific chemicals,
wear a respirator mask to avoid inhalation of vapors if directed on the
chemical label.
2. Wear non-slip, protective footwear. Use of pressure washer can create
puddles and slippery surfaces. Wear footwear capable of maintaining a
good grip on wet surfaces.
Prime the water
supply CAUTION: Never run the pump without the water supply connected and
primed. Operating the pressure washer without a sufficient incoming flow of
water will damage the pump.
If using city tap water:

Ensure that the city tap water ball valve is OPEN, and the tank feed ball
valve is CLOSED. (The ball valve you are not using must be closed
before starting the engine or pump cavitation could occur.)

Turn on the tap. Make sure the water supply is steady and flowing at a
rate 20% over the rated flow of your pump. (See Step 1 above, "Connect
Hoses, Water Supply, and Nozzle").
