WARNING – READ THIS MANUAL
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.
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 27: Step 3. Spraying
Operation Step 3. Spraying Safety rules for Before starting the pressure washer, review the following general safety operation rules for operation: Conditions for Use Know how to stop. Be thoroughly familiar with proper use of the equipment and all controls and connections. Know how to stop the pressure washer and depressurize system quickly if needed (see “Step 6. - Page 28 Operation 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.
- Page 29 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 30 Operation 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. Turn the heat switch ON and adjust the thermostat to the desired temperature.
- Page 31 Operation If spraying from an elevated surface, use fall protection because spray gun kickback can propel you off the elevated surface. When spraying from a ladder or scaffolding, ensure it is firmly anchored from sway or tip-over. Be aware of puddles and slippery surfaces. Ensure there is adequate drainage to prevent pooling of water.
- Page 32 Operation 8. The pressure washer is set and locked to the maximum rated pressure when it leaves the factory. To reduce the pressure, turn the unloader knob counterclockwise. (See Figure 11 below) 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.
