OPERATION REFER TO THE DIAGRAMS ON THE PREVIOUS PAGE
HIGH PRESSURE WASHER
1 Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness. Make
sure hoses are in good condition and the spray nozzle(s) is tight.
REFER TO THE AUTO-FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGES.
2. If you choose to use the automatic pump-out feature, connect the dump hose to the brass hose fitting
on the back of the machine, and place the open end of the hose in a drain. Make sure the drain hose
on the back of the vacuum tank is closed, and the lid is tight on the recovery tank. NOTE: never turn
ON the automatic pump-out switch unless you have removed the brass cap from the hose connector on
the rear of the machine. This pump will run continuously if it is turned on, and if the water can not be
pumped out (cap still screwed on) damage may occur to the pump.
If you choose not to use the auto pump-out option, just make sure the brass cap is on the hose
connector on the rear of the machine. CAUTION: do not turn the pump-out switch on if the cap is still
on the hose connector on the back of the machine.
3. If you choose to use the auto-fill feature, connect the fill-hose to the auto-fill valve (located over the
solution tank fill hole). Turn on the water source. NOTE: do not turn the water on full power. The water
flowing into the auto-fill system does not need a lot of pressure behind it. Allow the tank to fill with
solution. When you use the auto-fill system, the auto-fill valve will automatically turn on and turn off as
the tank empties and then fills. NOTE: If you are not going to use the auto-fill system,
just fill the
tank with water and cleaning chemical. Follow chemical directions regarding dilution and mixing. Do not
use harsh chemicals; they may damage seals in pumps and valves, and cause the pump to wear
prematurely. NOTE: Never put water in the tank with a temerature exceeding 54
° C/130 ° F.
4. Pre-spray the area to be cleaned with a pump-up sprayer. Follow chemical directions.
5. Plug in the power cord. Turn on the high pressure pump by placing the HIGH PRESSURE/HEAT selection
switch (2) in the UP position, to select the High Pressure Pump. NOTE: The high pressure pump and
the heat can not operate at the same time. NOTE: this switch is off when it is set to the middle
position and neither the high pressure pump nor the heater is selected.
6. The 85 bar pump is not self-priming; you will need to prime the high pressure pump using the ‘power
prime’ system: turn on both the pump and the vacuum, cover the hole in the hose barb with your
hand, then depress the Power Prime Pedal. This will pull trapped air out of the pump and into the
recovery tank
, priming the pump. You will notice a ‘tone’ change in the pump (smoother, with less of a
rattle), and the water being pulled into the recovery tank will change from a white, full of air stream of

CAUTION: IF FOAM OR WATER COMES OUT THE VACUUM EXHAUST,
TURN THE MACHINE OFF IMMEDIATELY
CAUTION : Never leave the 85 bar pump running if you are not actively using it
