4. Start gas/diesel engine
Refer to instructions in engine manual. You may need to hold wand trigger open while starting
engine in order to let it turn over more easily. MAKE SURE THAT THE ENGINE
EXHAUST IS NOT FACING ANY FLAMMABLE MATERIALS.
4. Pressure adjustment - The pressure regulator (unloader) is located on the pump (see diagram).
It controls the pressure being generated by the pressure washer. This regulator may be adjusted to
desired pressure by turning the adjustment knob. Turning the adjustment knob clockwise will
increase pressure. NEVER OPERATE SYSTEM AT A HIGHER PSI THAN THE
MAXIMUM RATING. This machine has been adjusted to operate at a specific maximum
pressure as per the machine specifications. Pressure may be reduced for lighter use by turning the
unloader counter clockwise. If continuing to turn the unloader clockwise does not increase the
pressure, then this implies the maximum has been reached for the system. Any further turning of
the unloader will cause the pressure to spike when the wand trigger is released, resulting in
possible damage to the machine. To avoid this effect, loosen the unloader (counter-clockwise)
until the pressure just starts to drop (see pump head pressure gauge) and until it no longer exceeds
the maximum pressure rating for the machine.
5. You are now ready to start the cleaning operation - Pull trigger on the gun and wand
assembly to start cleaning. To stop pressurized water, release trigger. DO NOT LEAVE UNIT
RUNNING WHEN NOT IN USE. If left running, water will continuously be forced through the
bypass hose and back into the pump, which will cause the pump to overheat.
6. To stop operation. Turn off engine. Squeeze and release wand trigger after shutting off to
relieve system of pressure.
7. Prior to storage – Inspect pressure washer for any damage or required maintenance. If your
machine is to be exposed to cold weather, please refer to winter pump instructions found in this
manual. If possible, do not allow unit to remain outside in the elements.
**Warning – If unit is left running while not in use, pump damage may occur. Do not leave unit
running while not in use!
