Correctly using the device
1. The machine must be set upright on a level, stable
surface.
2. The spray lance is affected by a thrust during operation
– therefore, always hold it firmly with both hands.
IMPORTANT:
Point the nozzle at the ground.
. Activate the trigger of the spray handle.
4. Always adjust the distance and thus the pressure of the
nozzle to the surface which is to be cleaned.
NOTE: The spray angle can be adjusted at the nozzle.
NOTE:
Do not cover the machine during operation. If the
machine is left or not used, it must be switched off (ON/OFF
switch) on the start.
It is normal for the pump to leak a little; this is necessary to
avoid damage to the pump when it is at a standstill.
End of operation
1. Turn off the ON/OFF switch (12).
2. Disconnect the plug from the socket.
. Shut off the water supply, detach water supply hose
and activate the spray handle to relieve the machine of
pressure.
WARNING!
Failure to follow the above instructions may
cause damage to the machine.
Maintenance and storage
WARNING!
Always disconnect the plug form the socket prior
to maintenance or cleaning.
To ensure a long and problem free working life, please take
the following advice:
• Wash off water hose, spray handle hose, spray lance and
accessories before mounting.
• Clean the connectors of dust and sand.
• Rinse the detergent spraying attachment after use.
Any repair should always be made by RYOBI authorized
distributor with genuine spare parts.
Cleaning of lance nozzle (Fig.15)
A clogging up in the nozzle causes a pump pressure which is
too high. This is why cleaning is required immediately.
1. Stop the machine and disconnect the nozzle.
2. Clean the nozzle.
IMPORTANT:
The cleaning tool should only be used
when the spray lance is detached.
. Flush the spray lance backwards with water.
The inlet filter must always be fitted inside the water inlet
pipe to filter out sand, limestone and other impurities, as they
will damage the pump valves.
Checking the water intake filter (Fig.16)
Clean the water inlet filters regularly once a month or more
frequently in accordance to use. Periodically check the
filter in order to prevent clogging, which could jeopardize
operation of the pump. To do this, unscrew the connection
coupling for the water inlet hose from the device and clean
the exposed inlet sieve by placing it under running water.
CAUTION:
Failure to fit the filter will invalidate the guarantee.
Cleaning of machine vents
The machine should be kept clean so as to let cooling air
pass freely through air vents.
Storage
Pump, hose and accessories should always be emptied of
water prior to storing as follows:
1. Long periods of nonuse: If the machine is going to be
stored for longer periods of time (i.e. over three months)
in a room where frost could develop, it is recommended
that the machine be filled with an antifreeze solution
(similar to the antifreeze solutions used for vehicles).
2. When the device is not used for an extended period of
time, lime deposits begin to form in the motor pump,
which in turn can lead to starting difficulties.
NEVER START UP A FROZEN MACHINE.
Frost damages are not covered by the guarantee!
Environmental protection
Recycle unwanted materials instead of disposing
of them as waste. All tools, hoses and packaging
should be sorted, taken to the local recycling centre
and disposed of in an environmentally safe way.
Machine not suitable for connection to the potable
water mains
To reduce the risk of injury, user must keep all
bystanders at least 15m away.
