PRESSURE RELIEF PROCEDURE

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. Shut off the water supply.
4. Disengage the trigger safety latch and trigger the gun to
relieve pressure.
5. Re-engage the trigger safety latch.
6. When checking or repairing unit, remove ignition cable from
the spark plug.
7. Before overnight storage, long term storage, or transporting
unit, disconnect the water supply and turn off the fuel supply
valve.

SHUTDOWN

1. Be sure all detergent is flushed from system.
2. Turn the engine OFF.
3 Turn the water supply OFF.
4. After the motor and water supply are turned off, trigger the
gun to depressurize the system.
NEVER turn the water supply off before turning
the engine / motor off. Serious damage could
occur to the pump and/or engine / motor.
NEVER disconnect the high pressure discharge
hose from the machine while the system is
pressurized. To depressurize, turn engine/motor off, turn water supply
off and squeeze gun trigger 2-3 times.
5. After each use, wipe all surfaces of the pressure washer with a
clean, damp cloth.

STORAGE

• Do not store the pressure washer outdoors.
• Do not store the pressure washer where it might freeze
unless it has been properly winterized.
Long Term Storage Instructions (more than 30 Days in
storage)
1. Remove fuel from the tank and run the pressure washer in a
normal operating mode until the engine stops from a lack of
fuel. Normal operating mode means actually spraying water
from the gun while the engine is running.
Alternate method – Add fuel stabilizer to gas in the tank and
run in normal operating mode for at least five minutes.
14
2. Stop the engine, turn off the water supply, and trigger the
gun to release pressure in the high-pressure hose.
3. Disconnect the water supply and high pressure hose from
the pump.
4. Allow the engine to cool.
5. Disconnect the spark plug wire and remove the spark plug.
6. Pour 1/2 oz. of engine oil into the spark plug hole.
Never pull the starter rope on the engine when
the spark plug is removed unless the spark plug
hole is covered. Fuel vapor from the hole can ignite by a spark.
7. Place a rag over the spark plug hole and slowly pull the
starter rope several times to distribute the oil.

WINTERIZING INSTRUCTIONS

1. Follow and complete the Long Term Storage Instructions.
2. Disconnect the spark plug wire.
3. Disconnect the high pressure hose from the pump.
4. Insert a 12 in. to 14 in. piece of garden hose into the pump
inlet.
5. Place a funnel in the other end of the garden hose.
Read the manufacturer's instructions for safe
handling and disposal of RV antifreeze.
6. Pour approximately 6 oz. of RV antifreeze into the funnel.
7. Pull the starter rope several times until the RV antifreeze
comes out of the pump outlet.
8. Disconnect the high pressure hose from the gun and drain
the hose. Hold the gun and lance in a vertical position and
squeeze the trigger to drain the water out.
TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE
WASHER
1. Never operate the unit without water.
2. Your pressure washer is not meant to pump hot water. Never
connect your pressure washer to a hot water supply as it will
significantly reduce the life of the pump.
3. Running the unit for more than one minute without spraying
water causes heat to build up in the pump. Running the unit
without spraying water can damage pump components.
