WATER SUPPLY- Test the water source to determine water hardness. If the hardness exceeds
seven (7) grains, a suitable water softener should be installed. Installing a water softener greatly
improves chemical action and prevents “spotting” on glass, chrome and other washed surfaces.
If local water pressure exceeds 60 PSI, a water pressure reducing valve must be installed.
If the water source is not adequate (capable of supplying a minimum of 3GPM or more than the
volume of the pump at a pressure of a minimum 20 PSI) a tank or other suitable water source
must be provided. (Running a pump without sufficient volume will damage the seals and or
shorten pump life dramatically).
CARE OF High Pressure hose
Following these suggestions will increase the life of your high pressure hose:
1. Do not drag hose over sharp objects that could damage its cover.
2. Do not allow hose to become a “trip hazard”.
3. Do not tug the hose if it is caught around tires. Dislodge without pulling stretching or
jerking the hose.
4. Do not drag hose “down the line” behind mobile wash units.
5. Do not leave hose out in freezing weather. If accidentally frozen, allow to thaw, remove
tip and flush before using.
6. Do not allow the hose to be run over. The wire braid will flatten causing a weak spot in
the hose leading to hose failure, and the hose will have to be replaced.
3.2 Setting up your cleaner
Every fuel burning appliance, including this pressure washer, depends on a proper mix of fuel
and air (by weight) for proper combustion. Therefore some adjustment of the air regulation to
the LPG burner may be necessary to take account of altitude and the resulting air pressure.
This is true whether your fuel is LPG, diesel or gasoline. Your Multi-Power hot pressure washer
was thoroughly tested and adjusted for optimum performance before it left our factory. The
factory is located approximately 200ft above sea level, and combustion settings are optional for
that elevation and below.
1. Before using the cleaner for the first time, check carefully to detect any fault or damage.
