2. Install the provided battery terminals as shown in
Figure 5.
3. To reduce the possibility of sparking attach the wires
to the battery in the following order. Refer to Figure 5.
First attach the red wire from the voltage regulator
and the red wire from the control box to the positive
“+” terminal of battery. Next, attach the black wire from
the control box and the black wire from the voltage
regulator to the negative “-” terminal of the battery. To
disconnect the battery remove the wires in the oppo-
site order as installed. Install battery box cover and
fasten in place.

INSTALLATION
Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer ser-
vice life, and lower maintenance cost.
IMPORTANT: The use of a backflow preventer on the
water supply hose is recommended and may be
required by local code.
The pressure washer should be run on a level surface
and in a protected area where it is not readily influenced
by outside forces such as strong winds, freezing
temperatures, rain, etc. The pressure washer should be
located to assure easy access for filling of fluids,
adjustments and maintenance. Normal precautions should
be taken by the operator to prevent moisture from reaching
the pressure washer. It is recommended that a partition
be made between the wash area and the pressure washer
to prevent direct spray from the wand from coming in
contact with the pressure washer. Moisture reaching the
equipment will reduce the pressure washer’s service life.
All installations must comply with the local codes covering
such installations.
Venting
DANGER: Do not run machine indoors or in an
enclosed area, as exhaust fumes may be hazardous
to your health.
DANGER: Do not operate machine in areas where
flammable vapors (gasoline, solvents, etc.) may be
present, as this machine may ignite the vapors.
CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordi-
nances. Consult local heating contractors.
If the pressure washer is to be used in an enclosed area,
a flue must be installed to vent burner and engine
exhaust to the outside atmosphere. Be sure the flue is
the same size as the burner exhaust vent on the pressure
washer. See Figure 1 for location. Poor draft will cause
the pressure washer to soot and not operate properly.
When selecting the location for installation, beware of
poorly ventilated locations or areas where exhaust fans
may cause an insufficient supply of oxygen. Proper
combustion can only be obtained when there is a sufficient
supply of oxygen available for the amount of fuel being
burned. If it is necessary to install the machine in a poorly
ventilated area, outside fresh air may have to be piped to
the burner and a fan installed to bring sufficient air into
the machine. Locate the pressure washer so that the flue
will be as straight as possible and protrude through the
roof at a proper height and location to provide adequate
draft. This oil fired pressure washer must have a draft
regulator installed in the flue (available from most heating
contractors). A draft regulator will permit proper upward
flow of exhaust flue gases.
In addition, the pressure washer should never be operated
in an enclosed area where high ambient temperatures
exist. High ambient temperatures (above 100
o
F) can
cause engine oil failure and will greatly reduce the engine’s
performance.
Gasoline Engine
This gasoline engine is preset for operation at altitudes
below 3000 feet above sea level. If operated at higher
altitudes, it may be necessary to install a high altitude
main jet in the carburetor. Contact an authorized engine
sales and service center for details.
