Operation
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.
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 fire. 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 backflow prevention
when connecting to a fresh water
supply. Install a backflow 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.
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.
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.
