OPERATING INSTRUCTIONS
1. Perform pre-start maintenance inspection on all applicable systems prior to operating
machine. This is essential for the safe, effective, and efficient operation. You will get optimum
performance from your system ONLY if these instructions and inspections are followed. Any
indication that the pressure washing system was not operated and maintained according to these
instructions may cancel the manufacturers’ warranty.
Location – See Installation Instructions in the included Water Heater Manual.
Controls – Make sure all controls are turned to off position.
Pump – Oil level - Level the pressure washer. Be sure oil level in pump is correct on dip stick. If
the level is low, add the correct oil to the proper level. USE ONLY SAE 30 W NON-
DETERGENT OIL OR HYDRAULIC 68. DO NOT OVER FILL.
Visually inspect all electrical components to assure they are in good condition, showing no
signs of exposure, breakage or splicing.
Visually inspect all hoses, nozzles and guns to assure they are in good condition. If
replacements are necessary they must be rated to withstand machine’s maximum operating
pressure and temperature.
2. Attach high-pressure hose to hot water outlet quick connector. Attach the other end of high
pressure hose (with quick coupler) to spray gun. Ensure that quick disconnect connections are
tightly locked together. Apply a sharp pull on hose to confirm they are secured.
Attach wand nozzle specific to task requirements (i.e. chemical or pressure wash).
[Quick Coupling Operation – Pull back sleeve end and insert male end into nozzle quick coupler,
release sleeve and confirm connection by pulling on nozzle].
3. Attach water source to water inlet located in front of float tank. The water source must be
attached with a good quality standard garden type hose (1/2” minimum is required). Connect
male fitting into female pump inlet fitting. Make sure that the inlet screen/filter is intact and
fitted correctly. Turn on water source. WATER MUST BE IN SUFFICIENT SUPPLY AND
PRESSURE MUST BE BETWEEN 20 –60 PSI TO ENSURE PROPER AND SAFE
OPERATION. Specific attention should be given if using a well water supply. Ensure water is
flowing from end nozzle with the trigger gun pulled. Deplete system of all air.
