WARNING!
Warning: Do not use this appliance without reading this instruction sheets.
- The electric supply connection shall be made by a qualified electrician and comply with
IEC60364-1.
- The Electric supply to this appliance should include either a residual current device that will
interrupt the supply if the leakage current to earth exceeds 30 mA for 30 ms or a device that
will interrupt the earth circuit.

- WARNING: This appliance has been designed for use with the cleaning agent supplied or
recommended by the manufacturer. The use of other cleaning agents or chemicals may
adversely affect the safety of the appliance.
- WARNING: Do not use the appliance within range of persons unless they wear protective
clothing.

directed at persons, live electrical equipment or the appliance itself.
- Do not direct the jet against yourself or others in order to clean clothes or foot-wear.
- Risk of explosion – Do not spray flammable liquids.
- Disconnect from the electrical power supply before carrying out user maintenance .
- High pressure cleaners shall not be used by children or untrained personnel.
- To ensure appliance safety, use only original spare parts from the manufacturer or approved by
the manufacturer.
- WARNING: Water that has flown through backflow preventers is considered to be non-
potable.
- WARNING: The machine shall be disconnected from its power source during cleaning or
maintenance and when replacing parts for mains operated machines by removing the plug from
the socket-outlet;
- WARNING: High pressure hoses, fittings and couplings are important for safety of the appliance.
Use only hoses, fittings and couplings recommended by the manufacturer.
- Do not use the appliance if a supply cord or important parts of the appliance are damaged, e.g.
safety devices, high pressure hoses, trigger gun.
- WARNING: If an extension cord is used, the plug and socket must be of watertight construction.
- WARNING: Inadequate extension cords can be dangerous.
_ This high pressure washer must not be used at temperatures below 0°C.
WARNING!
- Cord on drums should always be completely unwinded to prevent the cord from overheating. -
If an extension cord is used, the plug and socket must be of watertight construction.
- Inadequate extension cords can be dangerous.
- comply with the below-mentioned requirements for length and cord dimensions.
1.0 mm² max. 12.5 m
1.5 mm² max. 20 m
2.5 mm² max. 30 m
Power cord connections should be kept dry and off the ground.
_ If the power cord is damaged, it must be replaced by the manufacturer or his service agent or
similarly qualified person in order to avoid a hazard.
All keep the machine on a stable and flat surface during operation, handling, transportation and
storage. Sudden overturn of machine will cause injury to body.
In the event of accident or breakdown, switch off the machine immediately. (e.g. contact with
detergent: rinse with an abundance of clean water)
Attention!
Through poor conditions of the electrical MAINS, shortly voltage drops can appear when
starting the EQUIPMENT. This can influence other equipment (eg. Blinking of a lamp). If the
MAINS-IMPEDANCE Zmax < 0.335 OHM, such disturbances are not expected. (In case of
need, you may contact your local supply authority for further information.)
WARNING! ELECTRICAL SHOCK HAZARD
Improper connection of the equipment-grounding conductor can result in a risk of electrical
shock. Check with a qualified electrician or service person if you are unsure if an outlet is
properly grounded. DO NOT modify the plug provided with the appliance to fit an outlet, have a
proper outlet installed by a qualified electrician.
Mains power connection
The following should be observed when connecting the high pressure
washer to the electric installation:
_ The electric installation shall be made by a certified electrician and comply with IEC-364.
_ It is recommended that the electric supply to this appliance should include either a
residual current device that will interrupt the supply if the leakage current to earth exceeds 30 mA for
30 ms.
IMPORTANT! Only use water without any impurities.
If there is a risk of running sands in the inlet water (i.e. from your own well), an additional
filter should be mounted.
Safety devices
_ The unloader valve can reduce pressure if it exceeds pre-set values. The spray gun features
a locking device. When the pawl is activated, the spray gun cannot be operated.
Thermal sensor:
A thermal sensor protects the motor against overloading. The machine will restart after a few
minutes when the thermal sensor has cooled.

4. NAME OF PARTS: (FIG. 1、FIG.2)
5. PRODUCT DESCRIPTION
PURPOSE
The high pressure cleaner is designed to clean vehicles, machines, buildings, facades, etc.
in the private sector.
AREAS OF APPLICATION
Never use the machine in potentially explosive areas under any circumstances!
The operating temperature must be between 0 and +40 .℃
The machine consists of an assembly with a pump, which is encased in a shock absorbing
housing. For an optimal working position the machine comes with a lance and a non-slip
handle grip, whose shape and configuration comply with the applicable regulations.
Do not cover or modify the lance or the spray nozzles in any way.
The high pressure cleaner is designed to be used with cold or lukewarm (max. 60 ); higher℃
temperatures can damage the pump.
Do not use water that is dirty, gritty or contains any chemical products, as these could impair
operation and shorten the life of the machine.
Accessories can be used to carry out work with foam cleaners, sand spraying.
6. ASSEMBLY
Position the washer as NEAR as possible to the water supply.
The washer must be used standing on a secure, stable, positioned as shown. FIG.3.
Fit the lance into the gun and rotating it until the two parts are completely locked FIG. 4.
Connect the gun to the high pressure hose FIG.5.
Connect the high pressure hose to the water outlet on the washer FIG.6.
Connect the water supply hose to female coupler FIG.7, then connect to the water inlet of
the washer. The supply hose must have an internal diameter of at least 13mm (1/2 in.) and
must be reinforced. The water supply must be at least equal to the washer delivery capacity.
NOTE: The machine not suitable for connection to the potable water main (FIG. 14).
WARNING
The intake water temperature must not exceed 40℃. The water supply must not exceed 0.7 MPa.
CAUTION
The washer must only be used with clean water; use of unfiltered water of corrosive
chemicals will damage the washer.
Push the motor switch to “OFF” position FIG. 9.
Check that the electrical supply voltage and frequency (Volt/Hz) correspond to those specified
on the washer rating plate. If the power supply if correct, you may now plug in the washer.
7. OPERATION
Turn on the water supply tap fully.
Release the safety lock FIG.8, then press the trigger for a few seconds to allow air to
escape and to discharge residual pressure in the hose.
Keeping the trigger pressed, push the switch to start the motor FIG.9.
When re-starting the motor, always keep the trigger pressed.
NOTE:
THE MOTOR ONLY RUNS WHEN THE TRIGGER IS OPERATED.
CORRECT USE OF STANDARD ACCESSORIES
The washer is equipped with the adjustable nozzle.
Jet adjustment from pencil to fan FIG. 10.
WARNING: DO NOT ADJUST THE NOZZLE WHILE THE TRIGGER IS SQUEEZED.
RECOMMENDED CLEANING PROCEDURE
Dissolve dirt by applying detergent with the fan jet to the dry surface. On vertical surfaces,
work from the bottom upwards. Leave the detergent to act for 1 to 2 minutes, but do not
allow to dry out. Apply the high from the surface, working from the bottom upwards.
Avoid allowing the rinsing water to run on to unwanted surfaces.
STORAGE (FIG.11 – FIG. 13)
Switch off the washer.
Turn off the water supply tap.
After use, the detergent residuals should be removed from the tank.
Discharge residual pressure by pressing the trigger until no more water comes out of the
lance nozzle.
Engage the gun safety lock.
Remove the plug from the socket.
Operate the washer with non-corrosive/ non-toxic antifreeze before storing for the winter.
