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.
I MPORTANT: 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.
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.
XII.) Shut-Down Instructions
WARNING: Do not leave an operating machine
unattended.
Always shut the machine OFF and
relieve the pressure before leaving the machine.
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.
E. Remove garden hose.
F. Remove pressure hose.
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.
