Operating Instructions

X.) For Hot Water

If HOT water is desired, make sure there is fuel in the fuel tank, turn the heat switch ON, and adjust the thermostat to the desired temperature. The burner will fire when the trigger is squeezed. You may need to initially adjust your burner for peak performance. See the “Oil Burner” section under INSTALLATION. When the trigger is released a pressure switch automatically turns the burner off. Also, when the temperature setting is reached, the thermostat automatically turns the burner off.

IMPORTANT: Do not run the machine in hot mode without any fuel in the fuel tank. The fuel pump will be damaged if it is run dry.

Warning: It is important that the burner stops firing when the trigger is released. If the burner remains firing, discontinue use until the pressure washer is serviced. Extremely high temperatures can result in serious injury and equipment damage.

XI.) Cleaning

WARNING: Wear eye, ear, hand, foot and skin protection at all times while operating this pressure washer.

DANGER: Do not point the spray wand at yourself or at any person. Bodily injury may result from water under high pressure.

CAUTION: Be careful on painted or delicate surfaces. The pressure may damage the surface if the nozzle is too close.

IMPORTANT: Your spray gun is equipped with a built-in trigger safety latch to guard against accidental trigger actuation and potentially dangerous high pressure spray. Rotate the safety latch to the locked position when not spraying.

XII.) Shut-Down Instructions

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.

A.Turn heat switch OFF and run cold water through the coil for 3 minutes.

B.Turn engine OFF.

C.Turn water supply OFF.

D.Actuate spray gun trigger to relieve system pressure.

Safety Features

Safety Relief Valve

The safety relief valve is a backup safety feature. If the system over pressurizes, the safety relief valve will open and relieve system pressure.

The safety relief valve is located in the high pressure line between the unloader and the heat exchanger.

WARNING: If the safety relief valve ever discharges water, turn the engine off and do not use the machine until it is serviced.

Thermal Relief Valve

The thermal relief valve allows the pump to remain in bypass without risk of overheating the pump. If high temperatures are developed during bypass, the thermal relief valve will open and discharge hot water onto the

ground.

The thermal relief valve is located on the unloader bypass port.

A.) Hold the lance with two hands, have a sturdy stance. B.) The pressure washer is set and locked to the maximum rated pressure when it leaves the factory. .

WARNING: Do not alter the unloader valve’s maximum pressure. Excess pressures could cause serious injury and/or pump damage. Any alteration other than turning the adjustment knob will void your warranty.
