equipped, turn on the on/off
switch to the “on” position.
7. Start the engine.
If the engine is cold, completely close
the engine choke.
If the engine is warm, leave the
choke open or just partially closed.
Unlock the trigger safety latch on
the gun. Grasp the starter rope and
brace one foot on the chassis. While
squeezing the trigger on the gun,
pull the starter rope rapidly and
firmly. Continue holding the rope as
it returns. Repeat these steps until
the engine starts. In cool weather,
the choke may have to be kept
closed for 10 to 30 seconds to keep
the engine running. Otherwise,
open the choke as soon as the
engine starts.
When pulling the
starter rope, make
sure to keep your hand and arm clear
of the engine and cart components.
Never let the starter
rope return by itself.
Doing so could jam the recoil system.
8. If the engine does not start after two
or three pulls or if the rope is hard to
pull, squeeze the gun trigger to
release the pressure that has built up
in the high pressure hose. Repeat
Steps 7 and 8 until the engine starts.
After the engine starts, trigger the gun
3 to 5 times to get any trapped air out
of the system. After the spray becomes
constant, you may need to adjust the
pressure or the spray fan angle for the
optimal cleaning performance needed
(see pages 7, 8 and 9 for cleaning tech-
niques).
PRESSURE ADJUSTMENT
Some units have a pressure adjustment
knob located on the pump (see Figure
10). Turn the knob clockwise to
increase the pressure. Turn the knob
counter clockwise to decrease the pres-
sure. Do not try and force the knob to
turn. The knob may already be at
either the lowest or highest setting.
NOTICE
!
CAUTION
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 8 gpm (30 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 trig-
ger safety latch.
6. a. Honda Engines: Open the fuel
shutoff valve by pushing the shut
off valve lever to the right. Close
the choke (if engine is cold) by
moving the choke lever fully to
the left. Move the throttle, if
equipped, fully to the left to the
Run or Rabbit position. If
equipped, turn on the on/off
switch to the “on” position.
b. Briggs and Stratton Engines:
Vanguard Series: Open the fuel
shutoff valve by rotating lever to
the vertical position. Close the
choke (if engine is cold) by moving
the choke lever fully to the left.
Move the throttle, if equipped,
fully to the left to the Run or
Rabbit position. If equipped, turn
on the on/off switch to the “on”
position.
Intek Series: Open the fuel shut-
off valve by rotating lever to the
horizontal position. Close the
choke (if engine is cold) by moving
the choke lever fully to the right.
Move the throttle, if equipped,
fully to the right to the Run or
Rabbit position. If equipped, turn
on the on/off switch to the “on”
position.
c. Robin Engines: Open the fuel
shutoff valve by turning the lever
to the downward 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. If

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 clean-
ing 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 deter-
gents.
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 nec-
essary.
NOTE: Some units are equipped with a
low oil sensor that shuts the engine off if
the oil level falls below a certain level. If
the unit stops unexpectedly, check both
the oil and fuel levels. Check the oil level
each time you refuel the unit.
2. Check fuel level.
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 shut-
off 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 I.D.
of 5/8” and a length of 50 ft. (15 m)
or less.
Some local plumb-
ing codes require
backflow prevention when connecting
to a fresh water supply. Install a back-
flow preventer upstream from the
pump if necessary.
