Operation

SURFACE PREPARATION

The following cleaning procedure will help you organize your cleaning task and
ensures that you will achieve the best results in the shortest amount of time.
Remember to use the spraying / cleaning techniques mentioned in the following
section.
Before starting a pressure washer cleaning job, prepare the surface you intend to clean.
Clear furniture from the area and make sure that all windows and doors are closed
tightly. Also, protect all plants and trees near the cleaning area with a drop cloth. A
covering ensures that your plants won't be sprayed by the detergents.

START UP

ALWAYS use this start up procedure to ensure that the unit is started safely and
properly.
If water has frozen in the pressure washer, thaw the pressure washer in a
warm room before starting. DO NOT pour hot water on or into the pump;
internal parts will be damaged.
1. Check engine oil levels. Add oil as necessary.
2. Check fuel level. Add unleaded gasoline (rated 86 octane or higher) as required.
DO NOT refuel a hot engine. Refueling a hot engine could cause a fi re.
Use only fresh, clean regular or unleaded gasoline. Close the fuel shutoff
valve during refueling.
3. Attach a garden hose to the inlet side of the pump and connect it to the water
supply. Use a hose with an internal diameter (I.D.) of 5/8 in. (1.58 cm) and a length
of 50 ft. (15 m) or less.
Some local plumbing codes require backfl ow prevention when
connecting to a fresh water supply. Install a backfl ow preventer upstream
from the pump if necessary.
a. If inlet water pressure is over 100 psi, install a regulating water valve at the
garden hose connection.
b. Do not exceed 100˚ F (38˚ C) inlet water temperature.
NOTE: The inlet water supply must have a minimum flow rate of 5 gpm (19 lpm).
4. Turn the water supply ON.
Never run the unit dry. Be sure the water supply is completely turned on
before operating the unit.
5. Trigger the gun until water sprays from the tip indicating that all air is purged from
the system. Set the trigger safety latch.
6. Open the fuel shutoff valve by turning the lever to the right / "ON" position. Close
the choke (if the engine is cold) by moving the choke lever fully to the left. Move the
throttle fully to the left to the "Run" or "Rabbit" position. Turn the ON / OFF swirch
to the "ON" position (see Figure 18).
