Installing a Battery
Warning: Sulfuric acid is a corrosive poison.
Avoid contact with skin, eyes or clothing. Always
wear safety glasses. Always wear safety glasses
when working on or near the battery.
The engine will not run and the burner will not fire
without first installing a battery.
The battery box provides protection for the battery and
will accept a standard top post mount (Group 75)
automotive battery (The inside dimensions are 11-1/8"L
x 7-3/4"W x 10-1/8"H). The battery must be 12VDC, with
a minimum rating of 18 Ah (Amp-hour). When installing a
battery, always connect the red colored (“positive” or “+”)
cable first. When disconnecting a battery, always
remove the black colored (“negative” or “-”) cable first
Location
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life, and lower maintenance cost.
IMPORTANT: The use of a back flow preventer (Part
#222815 call 1-800-270-0810 to order) on the water
supply hose is recommended and may be required
by local code.
Place the pressure washer on a solid level surface in a
protected area where it is not readily influenced by
outside forces such as strong winds, freezing
temperatures, rain, etc. Locate the pressure washer for
easy access for filling fluids, adjustments, controls, and
maintenance. Position the machine so that ambient
lighting is sufficient for the surface you are cleaning to be
seen with ease. Use artificial light if needed.
Make a partition between the wash area and the
pressure washer to prevent direct nozzle spray from
coming in contact with the pressure washer. Moisture
reaching the equipment will reduce the pressure
washer’s service life.
Attaching Customer Supplied Water Feed
Tank (157598 only)
Warning: This unit can only be used with a tank. Direct
feed from a normal city water hookup can cause
cavitation and damage to your pump.
Caution: Make sure to follow these instructions.
Inadequate plumbing between a feed tank and the
pressure washer can cause damage to the pump from
cavitation. Cavitation will occur if you select too small of
fittings and hose to connect the feed tank to the pressure
washer.(We recommend ¾” hose and fittings or larger)
Also, place the pressure washer right next to the feed
tank so the connection hose will be as short as possible.
1.) Drill 1.5” diameter hole in bottom of the tank for the
supply line. Drill a 1.5” diameter hole in the tank at
least 1’ from the supply port for the return line. See
tank in parts explosion of 157597 for an example.
Both holes need to be drilled on flat surfaces of the
tank. Insert supplied bulkhead fittings into holes.
2.) Thread the supplied ¾” elbow fitting into the bulkhead
fitting for the supply line. Thread the supplied ¾”
hose barb fitting into the return line’s bulkhead.
3.) Use supplied ¾” connection hose or supply your own
(can be no longer than 6ft long). Make sure the
connection hose does not kink.
4.) Connect the supply line, from the pump, to the ¾”
elbow with the supplied hose clamp. Connect the
return line, from the unloader, to the ¾” hose barb
using the supplied hose clamp.
5.) Make sure bottom of the tank is level or higher than
the bottom of the skid frame.
6.) Do not pump flammable liquids or liquids containing
incompatible chemicals or solvents.
Insert Nozzles into Hose Reels Guides
(157597 only)
Insert grommets and nozzles into the hose reel
guides.
Gun Storage (157597 only)
