GENE AL SAFETY
•
To reduce the risk of injury, close supervision is
necessary when a product is used near children. Do
not allow the pressure washer to be used by children
or people who are not familiar with it.
•
Know how to stop the product and bleed the pressure
quickly by pressing the trigger (See the ‘Operation’
section on page 5). Be thoroughly familiar with the
controls.
•
Stay alert and watch what you are doing.
•
Do not operate the product 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.
•
This product 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 machine 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 machine should be switched off if it is not used
for periods longer than 3 minutes.
•
Maintain a constant water supply when the machine
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 machine 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 machine has been designed for only using
cleaning water. Do not use corrosive chemicals.
•
This machine 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 appliance 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.
•
Disconnect from the electrical power supply before
carrying out user maintenance.
•
To ensure the appliance safety, please use only
original spare parts from Osaki. Do not use the
machine before you have changed them if they are
damaged.
•
Store the pressure washer in a dry, secure place,
away from children.
•
If the supply cord is damaged, it must be replaced
immediately.
•
ever try to move the appliance 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.
Repair work on the Osaki Power Washer can
only be carried out by a trained service engineer.
A comprehensive in house repair and service
facility is available through your local agent.

Frost can destroy an incompletely emptied unit. The pressure washer must be stored in a
frost-free environment, ensuring that the hose is coiled without any kinks in it.
After long term storage without operation, it is possible that scales have formed inside the
machine, making it difficult to start. In such conditions it is recommended to turn off and
disconnect the power supply and rotate the motor by hand. This is achieved by putting a
screwdriver through the ventilation grill at the back of the pressure washer and turning the
motor several times (See fig 21). This will help to avoid excessive current draw on the
motor and the power supply.

MAINTENANCE

The Osaki 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
