Note on first time operation:
If this is the first
time you are using your pressure washer it is a
good practice to flush the system to remove any
foreign particles that may have accumulated
during shipping. To do this remove spray nozzle
from the end of the gun extension and operate the
pressure washer for 2 minutes. Without a spray
nozzle on the end of the gun extension water will
simply flow out at low pressure. This will allow any
foreign particles to be flushed from the system
which might otherwise plug the spray nozzle.
Caution:
Do not leave the pressure washer
operating with gun trigger closed for extended
periods of time as bypassing water from the
unloader could heat up and damage the pump.
Either turn power to the pressure washer off or
open the trigger gun occasionally to introduce
fresh water into the bypass.
Purging Air
To purge air from the pump, open the needle
valve labelled “OPEN TO PRIME” located on the
left front of the pump. Open the needle valve until
water flows out and all air is purged from the
pump. Close the needle valve tightly afterwards.
Pressure Adjustment
Your pressure washer comes equipped with a
pressure regulating unloader valve located on the
right front side of the pump. The unloader valve
drops the pressure on the outlet of the pump to
zero when the gun trigger is closed. This removes
the load on the pump and motor when you are not
spraying. The pressure regulating valve, located
on the left front side of the pump, acts as a safety
relief valve in case of unloader malfunction.
The unloader valve is preadjusted for the rated
pressure of the pressure washer. If necessary,
pressure can be adjusted by turning the adjusting
cap on the unloader either up (to reduce pressure)
or down (to increase pressure). Do not turn the
adjusting cap down too far as this may cause the
unloader not to unload properly. When turning the
adjusting cap down to increase pressure it may be
necessary to turn in the pressure regulating valve
on the left hand side of the front of the pump just
enough to stop water from exiting it.
Caution:
Do not exceed the rated pressure of
pressure washer.
Soap Container
Liquid soap may be added directly to the soap
container through the filler spout. If a powdered
detergent is used, the detergent should be
dissolved in a pail of hot water before adding to
the container. It is important that all the detergent
be dissolved before adding it to the soap container
as undissolved pieces may clog the soap strainer.
The soap solution should be made as strong as
possible as the soap control can be used for
metering the soap.
As the soap suction line feeds directly into the
water suction line of the pump it is important to
ensure that the level of soap in the soap container
remains higher than the end of the soap tube in
the container.
Soap Control
The soap control provides a simple yet effective
way to control the application of soap at high
pressure. The soap control is located beneath the
tee on the suction inlet of the pump. The soap
control consists of an on-off valve and a needle
valve.
To adjust the soap control turn the pressure
washer on and open the gun trigger such that you
are spraying. Open the on-off valve by moving the
lever to the vertical position and use the needle
valve to adjust the concentration of soap. Turn the
needle valve knob clockwise to decrease the
concentration or counter-clockwise to increase the
concentration. Once the desired concentration is
achieved, the needle valve can be left in this
position and the on-off valve used to turn soap on
and off.
