INSTALLATION
Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life, and lower maintenance cost.
IMPORTANT: The use of 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 fluids, adjustment
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 high-pressure wand from
coming in contact with the pressure washer. Moisture
reaching the pressure washer will reduce its service life.
All installations should comply with the local codes
covering such installations.
IMPORTANT: DO NOT run machine indoors or in an
enclosed area where high ambient temperatures
exist. High ambient temperatures (above 100°
F) can
cause engine oil failure and will greatly reduce the
engine’s performance.
Venting
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
lid. 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
will have to be supplied to 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.
Battery
WARNING: Batteries generate explosive gases dur-
ing normal battery operation. DO NOT expose the bat-
tery to flame or sparks as these gases may ignite.
WARNING: Battery fluid is highly acidic. If battery fluid
contacts skin or clothing, wash immediately with soap
and water. If battery fluid enters eye, immediately flood
eye with running cold water for at least 15 minutes
and get immediate medical attention.
1. Refer to
Figure 5
.
2. Install battery (battery not included) in battery box
as shown. Use a standard automotive battery mini-
mum 500 CCA (Cold Cranking Amps). It is recom-
mended that a dual cell battery (a battery with a
separate cell for emergency starting) be used.
3. To reduce the possibility of sparking attach the bat-
tery cables in the following order. First attach the posi-
tive battery cable (red) to the positive “+” terminal of
the battery. Next, attach the negative battery cable
(black) to the negative “-” terminal of the battery. To
disconnect the battery, remove the cables in the op-
posite order as installed.
4. Install battery box lid and secure with strap provided.
Oil Burner
Burner Air Adjustment:
The oil burner is preset for
operation at altitudes below 3000 feet. If operated at
higher altitudes, it may be necessary to adjust the air
band setting. Adjust the air band for a #1 or #2 smoke
spot on the Bacharach scale.
