10.4 Self-priming from open tanks/containers and
natural water sources
m DANGER
• Never draw water from a drinking water container.
• Never prime with liquids containing solvents such as paint
thinners, petrol or oil. Atomised spray from solvent is highly
flammable, explosive and toxic.
Use the self-priming equipment (not included in the scope of
delivery) consisting of:
• Intake filter
• 3 m reinforced suction hose
With this accessory the appliance can draw water to max.
0.5m above the water surface. This can take up to 1 minute.
• Immerse the 3 m suction hose completely under water to get
the air out.
• Connect the suction hose to the appliance and ensure that
the intake filter remains under water.
• Run the appliance without the hand spray gun attached until
water flows evenly out of the high-pressure hose.
• If no water flows out after 1 minute, switch the appliance
off and check the appliance. Once the water flows, switch
off the appliance and attach the hand spray gun and the jet
pipe so you can work.
It is important that the hose and coupling are of a good quality,
tightly fitted and that the seals are undamaged and inserted
straight. Leaky connections can impair the suction.
11. Operation
Check the device to make sure that all of the following steps
have been performed:
• Before commissioning the device, read and understand the
operating manual completely.
• Check that the bow-type handle (1) is tightly fitted.
• Check that oil has been poured into the engine crankcase to
the specified level.
• Pour the specified type of petrol into the fuel tank (15).
• Check that the hose connections are tightly fitted.
• Check that the high-pressure hose (6) has no kinks, cracks
or other damage.
• Provide a suitable water connection with sufficient flow.
• Ensure the device is level.
• Switch on the water supply.
ATTENTION
• Do not switch on the pump if the water supply is not con-
nected or switched on.
• Select the required nozzle (27) and insert it in the jet pipe
(11).
11.1 Starting the engine
ATTENTION
• Before first use, add engine oil (SAE10W30) and fuel
(regular unleaded petrol).
• Check the fuel and oil levels; top up as necessary.
• Provide adequate ventilation for the appliance.
• Ensure that the spark plug/spark plug connector (24) are
firmly fitted.
m CAUTION
• When starting using the pull starter (26) there can be a
kickback that can cause injuries to your hand.
11.1.1 Cold start (Fig. 13)
• Set the choke lever (8) to the “Choke” position.
• Set the on/off switch (19) to the “I/ON” position.
• Start the engine with the pull starter (26). Pull firmly on the han-
dle to do this. If the engine does not start, pull the starter again.
• After starting the engine, let the machine run for a few sec-
onds and then set the choke lever (8) to “Run”.
11.1.2 Warm start (Fig. 13)
• Set the choke lever (8) to the “Run” position.
• Set the on/off switch (19) to the “I/ON” position.
• Start the engine with the pull starter (26). Pull the handle
strongly for this.
11.1.3 After starting the engine (Fig. 1)
• Flip the trigger lock (4) on the hand spray gun (2).
• Hold the hand spray gun in a safe direction and pull the
trigger (3). This cleans the pump system of air and impurities.
11.2 Turning the engine off (Fig. 13)
• Run the appliance for a short while without load before you
switch it off so that the appliance can “after-cool”.
• Move the On/Off switch (19) to the “0/OFF” position.
11.2.1 After shutting off the engine
• Connect the water supply.
• Pull the trigger (3) until the appliance is depressurised.
11.3 Setting operating pressure and flow rate
The pressure and flow rate are fixed on this appliance and
cannot be changed.
11.4 Changing the nozzle (Fig. 7)
m DANGER
• Before changing the nozzle, switch off the appliance and
pull the trigger (3) to depressurise the appliance.
• Remove the spark plug connector (24).
11.4.1 Using the spray nozzles (Fig. 7, 14)
The quick-release connector on the jet pipe (11) can be used to
switch between five nozzles (27).
Proceed as follows to change the nozzles (27):
• Pull back the ring of the quick-release connector and pull off
the nozzle (27).
• Select the required nozzle:
-Soft jet: 40° (white) or 25° (green)
-Hard jet: 15° (yellow) or 0° (red)
-Cleaning agent: Black
• Pull the ring back, insert the selected nozzle (27) and re-
lease the ring. Pull on the nozzle (27) to check the tight fit.
• The best cleaning results are achieved when the nozzle (27)
is held at a distance of 20 to 60 cm from the surface to be
cleaned. If the distance is too short, the sprayed surface can
be damaged.
• When cleaning car tyres, maintain a distance of at least 30 cm.
