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 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 a Water Feed Tank (157594 only) 

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 not occur if you select large fittings and 
hose to connect the feed tank to the pressure washer.   
Also, place the pressure washer right next to the feed 
tank so the connection hose will be as short as possible. 
 

 
1.) Use ¾” connection hose no longer than 6ft long.  
2.) Make sure the connection hose does not kink. 
3.) Make sure all fittings are ¾” or larger.  
4.) Do not use 90

°

 elbow fittings unless absolutely 

necessary. 

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. 

7.)  Reroute the easy start valve so it discharges back to 

the feed tank.  This will aid pump priming on initial 
start up.  The easy start valve is located below the 
unloader.  See Machine Component Identification for 
location of unloader.
