WARNING – SPECIAL HAZARDS

Exhaust from both the engine and burner contains carbon monoxide, a

poisonous gas that can cause carbon monoxide poisoning and possible

death if inhaled. ONLY run pressure washer OUTDOORS and at least 20

feet from the home, away from windows, vents and air intakes, to allow

proper ventilation. 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.

High-pressure spray can cause serious skin or eye injury, including injection injury

if fluid pierces the skin. Injection injury can result in blood poisoning and/or

severe tissue damage.

Hot spray can scald and burn skin.

Hot surfaces of wand, engine and burner, as well as hot exhaust from both

the engine and burner can cause burns.

Spray discharge can cause puddles and slippery surfaces.

Spray-gun kickback can cause operator loss of balance and falls.

High-pressure spray can cause surface damage and flying debris.

Engine and burner sparking can ignite fuel or other flammable liquids or

vapors in the vicinity.

Hot exhaust from engine and burner can ignite combustible materials.

Cleaning chemical vapors or contact with skin may be hazardous.

Spray contact with electrical sources can cause electric shock.

Page 18: Step 3. Select A Suitable Worksite
Before Each Use Step 3. Select Suitable Outdoor Worksite Before using the pressure washer, you must understand the criteria for selecting a suitable location for operation. Note that this pressure washer is for OUTDOOR USE only. WARNING You must choose a suitable site for operating your pressure washer to avoid equipment damage and/or injury and possible death from carbon monoxide poisoning, fire/explosion, uncontrolled equipment movement/tip over, or slips and falls.
Page 19 Before Each Use WARNING Never attempt to attach ductwork to the engine muffler or burner exhaust to allow for installation inside an enclosure. This could cause hot air deflection, heat build-up, and increased exhaust backpressure, resulting in possible exhaust leakage or overheating and damage to the pressure washer.

Page 24 Operation  It protects the pump from damage because no chemical passes through the pump. CAUTION: Certain chemicals, such as bleach or those containing muriatic acid, will cause pump damage if introduced upstream through the pump's water inlet.  It mixes the cleaning chemical into a low-pressure spray. Cleaning chemicals applied under low pressure adhere better to the surface being cleaned, allowing the formula time to react and remove dirt more effectively.
Page 25: Step 3. Spraying
Operation 4. Submerge the suction strainer connected to the braided chemical hose into a bucket containing the chemical solution. See Figure 10. Step 3. Spraying Safety rules Before starting the pressure washer, review the following general safety for operation rules for operation: Conditions for Use Know how to stop.
Page 26 Operation 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.
Page 27 Operation Start engine Start the engine to power the pump. 1. Make sure water supply is connected and primed. CAUTION: Running the pump dry will cause damage and void the warranty. 2. To prevent accidental spraying, engage the safety latch on spray gun trigger by rotating it to the locked position.
Page 28 Operation CAUTION: Do not run the machine in hot mode without fuel in the burner's fuel tank, or damage can occur. 3. Make sure the engine throttle is all the way open. If it is not, the engine will not supply adequate voltage to the burner, resulting in smoke coming from the heat exchanger during operation.
Page 29 Operation balance from kickback forces, and wet surfaces can be slippery. Keep good footing and balance at all times. Do not overreach. Do not stand on unstable support when spraying. If spraying from an elevated surface, use fall protection because spray gun kickback can propel you off the elevated surface.
Page 30 Operation WARNING: Do not attempt to alter the unloader valve's maximum pressure. Excess pressure could cause serious injury from escaping high-pressure fluids and/or pump damage. Any alteration other than turning the adjustment knob will void your warranty. Unloader Figure 11 If temporarily interrupting spraying, rotate trigger safety latch downward to the locked position to guard against accidental trigger release.
Page 31: Step 4. Stopping
Operation Step 4. Stopping Stop the engine using the following steps: WARNING: Never disconnect the high-pressure hose from the pump or spray gun while the system is pressurized. Relieve pressure by squeezing the spray gun trigger after the engine is turned OFF.
