OPERATION
To reduce the risk of bodily injury or property damage,
always follow this procedure whenever spraying is
stopped, when work is completed, and before checking or
repairing any part of the system.
1. Engage the trigger safety latch.
2. Turn the unit off.
3. Remove the ignition cable from the spark plug.
4. Shut off the water supply.
5. Disengage the trigger safety latch and trigger the gun
to relieve pressure.
6. Re-engage the trigger safety latch.
7. Before overnight storage, long term storage, or
transporting unit, disconnect the water supply and
turn off the fuel supply valve.
This pressure washer uses a pump that is equipped
with an automatic thermal relief valve. The thermal
relief valve will automatically open after approximately 2
minutes passing, without the pulling of the gun trigger,
while the engine is running. Running the engine and not
pulling the trigger causes the water temperature inside
the pump to heat up. When the temperature exceeds
140º F (60º C), or after approximately 2 minutes of non-
gun use, the thermal relief valve automatically activates.
When the valve is activated, it opens to allow fresh/cool
water flow into the pump and hot water to escape. As a
result of the valve opening, hot water inside the pump
will spray out through the Thermal Relief Valve. When
the pump cools, the valve automatically closes.
Stopping the Engine
1. Turn the Fuel Valve to the “OFF” position.
2. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
3. Press the ignition switch to the “OFF” position.
4. Depressurize system
a. Turn off water supply.
b. Point gun/wand in safe direction. (Away from
people, animals or electrical outlets)
c. Depress trigger to depressurize system.
Running the unit for more than two minutes without
spraying water causes heat to build up in the pump.
CAUTION
In the event that the pump gets too hot, a thermal relief
valve will open to release the hot water.
Running the unit without spraying water can damage
pump components and will void your warranty.
Never operate your pressure washer without water.
CAUTION
Water leaving the valve and/or gun after the valve has
become activated may be hot. Make sure the pressure
washer is in a location that is not sensitive to hot water,
and has a clearance space around it of a minimum
distance of 3 ft. (91.4 cm) DO NOT point the gun at any
animal, human, or surface to avoid any damage and/or
injury caused by hot and/or pressurized water
CAUTION
Never connect your pressure washer to a hot water supply.
CAUTION
Connecting your pressure washer to a hot water
source will significantly reduce the life of the pump
and will void your warranty.

Detergent Use
The use of detergents can dramatically reduce cleaning
time and assist in the removal of difficult stains. Many
detergents are customized for pressure washer use on
specific cleaning tasks. Pressure washer detergents are
as thick as water. Using thicker detergents – like dish
soap – will clog the chemical injection system.
System flush
After using detergents, flush the suction system by placing
the detergent suction tube into a bucket of clean water.
You can effectively clean surfaces by combining the
chemical action of detergents with high pressure rinses. On
vertical surfaces, apply the detergent starting at the
bottom and work your way upward. This method prevents
the detergent from sliding down and causing streaks. Begin
high pressure rinsing at the bottom and work
your way upward. On particularly tough stains, use a brush
in combination with detergents and high pressure rinsing.
Use only detergents specially formulated for pressure washers.
NOTE
It is recommended that the inlet water temperature not
exceed 104º F (40º C).
