7. Make sure that pulse actuator lever is rotated counter-
clockwise in the "Pressure" position.
8. Wash Wand Nozzle Adjustments – By rotating the
nozzle, the wash pattern can be adjusted from a fine
stream to a wide fan type spray. By pulling the nozzle
forward (low pressure) and backward (high pres-
sure), the pressure can be adjusted. Make sure that
the nozzle is pulled back to the high pressure position
to start operation.

9. Wash Wand Lock Out – the wash wand includes a
lock out on the back of the trigger. Flip the lock out
down to prevent the operation of the trigger when the
wash wand is not in use.
10. With the wand pointed in a safe direction, squeeze the
wash wand trigger to reduce pressure and allow the
engine to be started. Following the starting instructions
supplied in the engine manual, start the engine. Allow
the engine to warm up. Release the trigger as soon as
the engine starts.
11. With the wand pointed in a safe direction, squeeze the
wash wand trigger. Turn the unloader valve while
monitoring the pressure gauge to adjust the pres-
sure as desired. Do not exceed the machine pressure
rating. Release the wash wand trigger.

Pressure Washer Operation

1. When using as a pressure washer use both hands to
grip and direct the wash wand for greater control.
Never direct the wash wand at people. High pressure
fluid can inject under skin resulting in serious injury.
Never direct wash wand at electrical equipment or
wiring to reduce the risk of electrical shock.
2. Control the flow of water with the trigger. Use care
when using the pressure washer. Holding the nozzle
too close to a surface can damage it. Test a small, in-
conspicuous area to confirm the settings work as
desired.
3. Do not allow the jetter to run for extended period of
time with the trigger OFF. When the trigger is OFF,
water recirculates in the pump and it causes the
water to heat up. This can cause the pump thermal
overload to open.

Maintenance Instructions

Before performing any maintenance, engine switch
should be in OFF position and spark plug wires
should be disconnected to prevent inadvertent op-
eration. Press foot valve or wand trigger to release
any fluid pressure in system.
Always wear safety glasses and gloves when per-
forming any maintenance to help protect against
drain chemicals and bacteria.

Cleaning

The hose should be cleaned as needed with hot, soapy
water and/or disinfectants. Do not allow water to enter

4. Once pressure washing is complete, release the trig-
ger and turn OFF the engine as directed in the engine
manual. Squeeze the trigger to release system pres-
sure. Never leave the system pressurized.
1. If needed, attach the detergent injector to the outlet
port. Remove the output hose and attach the deter-
gent injector with arrow on the unit pointing the same
direction as the water flow. Use thread sealant to
prevent leaks. Reattach the output hose.
2. Attach the siphon hose to the detergent injector.
Place the strainer end of hose into the detergent
container. Only use detergents designed for use with
pressure washers. Follow all detergent instructions.
Do not spray flammable liquids or toxic chemicals.
Other detergents, solvents, cleaners, etc. can damage
the jetter, or cause serious injury.
3. When pressure washing, detergents are only dis-
pensed when wash wand nozzle is in the low pres-
sure position. Pull the nozzle forward to the low
pressure position to dispense detergent.
4. During operation, the detergent application rate can be
adjusted by turning the sleeve on the detergent in-
jector. Counter-clockwise increases the amount of
detergent, clockwise decreases.
5. When detergent application is complete, remove the
strainer from the detergent, place into a bucket of
clean water and flush the system of any detergent.
