►
The pressure-washer can suck detergents and
other chemicals from a separate tank
►
Place
the chemical or detergent into the separate tank
►
Caution; add water to chemicals or detergents
too viscous to be sucked
►
Place the hose in the
independent tank (7)
►
Select the black nozzle for
chemicals
►
Start spraying
►
After using chemicals
put clean water into the independent tank and
draw it through chemical injection system to rinse
system thoroughly
►
If chemicals are being left in
the pump, the pump could be damaged
►
Warning;
chemicals or detergents will not siphon when lance
is in the high pressure setting.
OPERATING INSTRUCTIONS.
►
Important; before operation, check if every nut
and bolt are tight enough and check whether the
supply power and water can meet the demand of
pressure-washer
►
It is also important to check water
filter before using the pressure-washer
►
Important;
a well-cleaned filter means good performance and
long life for the pressure-washer
►
Connect the
water supply to the inlet port by a reinforced hose
►
Caution; the pressure-washer does not have a flow
switch, water source must provide 15 liter per minute
►
Caution; the temperature for the inlet water should
be not over 50°C
►
Connect wand to gun and tighten
securely (8)
►
Insert the quick connection plug of the
high pressure hose into the water outlet, and another
side should be tightened with the gun trigger (9).
ELECTRICAL SUPPLY.
►
Make sure that the mains voltage is the same
as shown on the identification label on the
pressure-washer
►
Warning; make sure that the
plug complies with your local regulations, and it is
provided with ground connection
►
Warning; the
power outlet must be protected by a residual circuit
breaker with a sensitivity of less than 30 mA
►
Do
not connect other appliances to the same outlet
►
Warning; insert the plug after checking that the
switch off the pressure-washer is in the off position.
STARTING.
►
Connect water supply, then open the gun trigger
►
Switch on the pressure-washer
►
Warning; in
case of power failure during operation, turn the
pressure-washer off for safety reasons
►
Hold
the gun in the open position for a few seconds to
drain the air from the hose
►
At this point, adjust
the pressure-washer according to your pressure
requirement
►
Please remind that it is better not
to exceed the normal working pressure, therefore
please use the maximum pressure as less as
possible
►
During washing, the spray head should
not be far away from the surface ►Warning; do not
use the pressure-washer when persons are within
the reach of the jet
►
Stop the gun after ending the
washing and then turn off the engine (in not more
than 2 minutes), because the unloading valve is still
moving after stopping the gun, the water will flow
in circle in the pump, which will make the water hot
and damage the seal ring or the other accessories if
long time passed
►
During the operation, it is normal
if there is a little water leaks out from the pump,
which will not affect to use the pressure-washer.
SAFETY VALVE.
►
The safety valve also functions as a pressure
limiting valve. When the gun trigger is released,
the safety valve opens and the water recirculates
through the pump inlet.
STOP.
►
When you finish the washing, switch off the unit
and hold the gun in the open position for a few
seconds to drain the water from the hose.
CHANGE PUMP OIL.
►
The level of the oil must be checked periodically
►
Very important; the oil must be changed after the
first 50 hours of work and successively after every
100 hours
►
In any case, oil must be changed at
least once a year
►
Use oil type SAE 15W-40 or
equivalent motor oil
►
Release the old pump oil
completely through the oil outlet plug (10)
►
Install
the oil outlet plug again and fill the clean kerosene
in the crankcase (11)
►
The kerosene level should
be slightly over the center line of the oil mirror (12)
►
Then run the pressure-washer without loading
about 10-15 seconds, then stop and release all the
kerosene
►
Then fill the new oil
►
The oil level should
be slightly over the red mark of the oil mirror.
STORING AND/OR FREEZING.
►
If the pressure-washer is to be stored in a place
where there is risk of freezing, or it is to remain unused
for more than three months, it is recommended to
place some antifreeze into the pump
►
Important; long
periods of disuse may lead to the formation of lime
scale deposits, that should be cleaned.
MAINTENANCE.
►
If the pressure-washer will not be running for a
long time, you should drain the water completely
