GE ERAL SAFETY
•
Read the safety instructions before using the pressure washer.
•
To reduce the risk of injury, close supervision is necessary
when the product is used near children. Do not allow the
pressure washer to be used by children or people who are not
familiar with it.
•
The pressure washer is intended to be used at a temperature
above 0 degrees.
•
This pressure washer 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 machine.
•
Wear appropriate safety clothing.
•
Know how to stop the pressure washer and bleed the pressure
quickly by pressing the trigger (See the ‘Operation’ section on
page 4). Be thoroughly familiar with the controls.
•
Stay alert and watch what you are doing.
•
Do not operate the pressure washer when tired or under the
influence of alcohol or drugs.
•
Keep operating area clear of all people and clutter.
•
Do not over reach or stand on an unstable support. Keep a
good footing and balance at all times.
•
The pressure washer must be grounded. The plug must be
plugged into an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded.
•
When working outdoors only use suitably approved extension
cables with a minimum conductor cross section of 1.5mm2.
The plug connectors must have earthing contacts and be
waterproof. Always disconnect the extension from the mains
electricity supply, before disconnecting the pressure washer
from the extension cord.
•
Do not start and run the pressure washer in the rain or stormy
conditions. Keep all connections dry and off the ground. Do not
touch the plug or sockets with wet hands. It is very important
not to let water leak into the machine.
•
The pressure washer should be switched off if it is not used for
periods longer than 3 minutes.
•
Maintain a constant water supply when the pressure washer is
running. Without water circulation damage will be caused to
the sealing rings of the machine.
•
It is necessary to turn on the spray lance within one or two
minutes after the pressure washer has been started.
Otherwise, the temperature of the circulating water within the
machine will soon rise to a critical point, which will cause
damage to the sealing rings inside the machine.
•
Do not start and run the pressure washer in a place which is
excessively cold.
•
This pressure washer has been designed for only using
cleaning water. Do not use corrosive chemicals.
•
This pressure washer must be connected to a cold water
source.
•
Hold the spray lance firmly when in use as there is a chance it
might swing back with the force that is inside it.
•
Do not use the pressure washer within the range of persons
unless they are wearing protective clothing.
•
Do not wash any objects which are a health hazard e.g. asbestos.
•
High pressure jets can be dangerous if subject to misuse. The
jet must not be directed at persons, live electrical equipment or
the appliance itself. Pressure washers should not be pointed
less than 30cm away from tyre walls or tyre valves, as it may
be possible to damage them.
•
Do not direct the jet against yourself or others in order to clean
clothes or footwear.
•
Do not spray flammable liquids as this could cause the risk of
an explosion.
•
Disconnect from the electrical power supply before carrying out
user maintenance.
•
To ensure appliance safety, please use only original spare
parts from or recommended by the manufacturer. Do not use
the pressure washer before you have changed them if they are
damaged.
•
Only allow a qualified person to carry out any maintenance or
repairs only using the manufacturer’s approved parts.
•
Store the pressure washer in a dry, secure place, away from
children.
•
If the supply cord is damaged, it must be replaced immediately.
Always check the electrical cables etc and the appliance
before and after every use for any signs of damage/wear and
tear. If any signs of damage have been found discontinue use
immediately and contact a qualified engineer.
•
Never try to move the pressure washer by pulling it with the mains
lead. Do not allow the mains lead to be pulled around corners or
sharp edges. Do not run the pressure washer over the lead.

SAFETY INSTRUCTIONS
For your safety, please read the instruction manual before using
accessories.
•When connecting or disconnecting accessories, make sure the
pressure washer is off and discharge hoses are under pressure.
•Always wear appropriate protective clothing such as goggles,
gloves and sturdy shoes or boots.
•In case of exposure to spray mist, wear a respirator.
•Ensure that no person or animal is in the work area.
GENERAL NOTICE FOR USE
•Each method of cleaning can damage the object to be cleaned or
the environment. Therefore test the impact of cleaning prior to use.
We disclaim any responsibility for damages of any kind. Exercise
great caution on soft materials such as joints or fragile parts of
vehicles such as bearings, etc.
TURBO LANCE (7)
•Rapidly rotating pencil jet designed to eliminate tough dirt on large
surfaces.
Note: Use only on very resistant surfaces. Test impact in a suitable
location to exclude material abrasion, crack formation or infiltration
beneath surfaces.
ACCESSORY KIT I STRUCTIO S
BRUSH ATTACH ENT (5 & 6)
To attach brush to spray lance (See fig 9):
•Screw coupling part (A) onto the end of the brush.
•Insert brush into the end of the spray lance, then turn and lock to
ensure a firm connection.
•Installing or removing components of the device should take place
only when the pressure washer is turned off, unplugged and the
pressure has fallen.
COUPLINGS (3 & 4)
Note: When new, it may be necessary to pull vigorously to remove the
adapter.
PIPE CLEANING HOSE (1)
•This is an ideal choice for cleaning pipes and drains with a
diameter of at least 40 mm (1.5 ") and a minimum radius of 70 mm
(2.75 ").
•If the high pressure hose is not fixed, it can move uncontrollably
and its powerful jet of water can injure people.
•Do not activate the high pressure jet nozzle until hose is at least
50cm inside the pipe to be cleaned.
•Once the high pressure jet is activated, never completely remove
the high pressure hose to clean the pipe.
•When cleaning is complete, turn off the pressure washer and
disconnect the pipe cleaner from the high pressure gun.
Note: The hose must be inserted in the gun base unit. You may need
to disconnect the cleaning lance or other accessory from the gun first.
Note: Be aware of the possibility of dirty water splashing backwards
and contaminating the environment.
HIGH PRESSURE SANDBLASTING KIT (8)
Note: The hydroblasting eliminates dirt, rust and paint etc. but the
water and sand particles can also damage the object to be cleaned.
Assembly:
•The nozzle must be inserted on the pistol grip of the basic device.
If applicable, you must first remove the lance previously inserted.
•The suction pipe must be dipped into the container that contains
silica sand or other blasting agent. Protect container with sand
against moisture.
•As soon as the water flows at high pressure through the cleaning
lance, sand is sucked by the suction pipe and mixed with water in
the cleaning lance. Silica sand grain or 0.2 to 2 mm aluminium
silicate can be used as sand blasting.

WATER INLET
The Osaki high pressure washer is maintenance-
free. However regular inspection of the water
inlet filter on the side will prevent any blockage
restricting the water supply to the pump
(See fig 7).
CLEANING PIN
1. Switch off and unplug from the main power
supply. Using the included tip cleaner, insert
into the nozzle hole and move back and
forth until debris is dislodged (See fig 8).
2. Remove additional debris by back-flushing water through the nozzle. To do this, place the end of a garden hose (with water running) to the end
of nozzle for 30-60 seconds.
