SETUP
Initial Assembly
To facilitate in the shipment of your pressure
washer, some items require minor assembly.
Refer to the
instructions.
Lubrication
Prior to initial operation ensure that the oil level of
the pump is to the halfway mark of the oil gauge
window. Do not overfill. Use only Magikist high
pressure pump oil or equivalent non-foaming, nondetergent, 40 weight #1 compressor oil. Do
use automotive, transmission, or hydraulic oils, or
brake fluid.
Motor Voltage
Ensure that your power supply matches that of the
pressure washer. Do not use any other circuit
unless the motor is rewired by a licensed
electrician. If the pressure washer is unwired, a
Startup Procedure
Ensure that the oil level of the pump is to the
halfway mark of the oil gauge window as
described under Setup.
Attach the water supply hose to the water inlet
connection and turn the water on. Leave the water
supply turned on.
WARNING: IF CONNECTION IS MADE TO A
POTABLE WATER SYSTEM, THE SYSTEM
SHALL BE PROTECTED AGAINST BACKFLOW.
ADVERTISSEMENT: SI CET APPAREIL EST
RACCORDÉ À UN RÉSEAU D’EAU POTABLE,
CE DERNIER DOIT ÊTRE PROTÉGÉ CONTRE
LES RETOURS.
Initial Assembly sheet included for
licensed electrician should be retained in order to
carry out the proper installation.
Water Inlet Connection
The water inlet connection is a 3/4” female hose
coupling located on the front right side of the
water tank. It is connected to a float assembly
which automatically maintains the correct water
level in the water reservoir.
not
Attach your water supply hose to the water inlet
connection and turn the water on. Leave the water
supply turned on. Ensure that your water supply is
of adequate capacity such that the water reservoir
does not run empty.
Do not disconnect the suction line between the
pump and the water reservoir and feed the pump
directly without the use of a pressure reducing
valve to reduce inlet pressure to 20 PSI.
OPERATION
Ensure that the power switch for the electric motor
is in the OFF position. Connect the electric motor
to the power supply.
Grasp the trigger gun firmly and turn the power
switch for the electric motor to the ON position.
Pull back on the trigger of the spray gun to spray.
If after a short while only a trickle of water is
coming out the the spray nozzle or if the water is
spurting out, you may need to purge air from the
pump. See the subsection
instructions on purging air from the pump.
WARNING: DO NOT SPRAY ELECTRICAL
APPARATUS AND WIRING.
ADVERTISSEMENT: IL EST DANGEREUX DE
TROP ARROSER LE MATÉRIEL ET LES
CÂBLES ÉLECTRIQUES.
Purging Air for
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.
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.
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.
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.
Caution: Do not exceed the rated pressure of
pressure washer.
MAINTENANCE
Pump Lubrication
Always ensure that the oil level of the pump is to
the halfway mark of the oil gauge window. Do not
overfill. Use only Magikist high pressure pump oil
or equivalent non-foaming, non-detergent, 40
weight #1 compressor oil. Do
transmission, or hydraulic oils, or brake fluid.
Change crankcase oil after first 50 hours of
operation, after which change oil at regular
intervals of 500 hours or less depending on
operating conditions. Oil can be conveniently
drained via the drain cock and tube located near
the rear side of the pump crankcase.
Each plunger has an oiler that is accessible
through the plunger cover. Oil each oiler every
100 hours of use or once a week, whichever
comes first.

HELPFUL INFORMATION
Using Soap
It is good practice to run the pressure washer with
soap off for approximately two minutes at the end
of the day’s washing. This helps to remove any
soap from the pump which might otherwise
deposit on the valve seats.
Acids, Alkalies, or Abrasive Fluids
Consult factory before using any of these fluids in
the soap reservoir.
Water Suction Strainer
Ensure that the strainer at the end of the water
suction hose in the water reservoir has no breaks
in the screen and that it is free of particles which
might restrict flow. Never operate the pressure
washer without the strainer. Foreign material
entering the pump can easily create problems or
contribute to premature wear.
Soap Suction Strainer
Ensure that the strainer at the end of the soap
suction tube in the soap container has no breaks
in the screen and that it is free of particles which
might restrict flow. Never operate the pressure
washer without the strainer. Foreign material
entering the pump can easily create problems or
contribute to premature wear.
Freezing Conditions
The pressure washer must be protected from
freezing conditions. If the washer is to be exposed
to freezing conditions, the pump must be well
drained. Alternately, anti-freeze of sufficient
strength to avoid freezing can be run through the
pump. In addition the soap container and all hoses
and accessories should be well drained to avoid
damage from freezing conditions.
Your pressure washer was designed and constructed
with safety foremost. When using the washer it is best
to observe the following precautions:
• Always hold the gun and extension firmly in both
hands during operation.
SAFETY
• Always keep high pressure spray away from people
and electrical apparatus and wiring.
Always keep clear of moving belts and pulleys.
•
• Never disconnect high pressure hose during
operation.
