This enables the pressure washer to draw water up to 0.5 m
above the water level in the source in approximately 15 sec-
onds.
Submerge the 3 m hose in water to displace the air. Connect
the 3 m supply hose to the pressure washer ensuring that the
inlet strainer remains submerged in the water source.
Run the pressure washer with the gun disconnected until a
steady flow of water appears from the high pressure hose.
Stop if this has this has not been achieved within 25 seconds
and check all the connections. Switch off and connect the
gun, lance and nozzle to operate.
Troubleshooting
Problem
Motor refuses to start
Motor stops
Fuses blow
Motor starts but no pressure
Motor "sounds" but fails to start
Pressure pulsating
Pressure too low, but steady
Note: Several types of accessory will nor-
mally deliver a lower pressure

It is important to ensure that all hose and coupling connec-
tions are of good quality, air tight and that all washers are in
good condition and correctly seated in place. Failure to do so
may affect the self priming performance.
Water Tanks with outlet connections
When connecting the pressure washer to a water tank with a
suitable tap outlet, first connect the supply hose (not provid-
ed) to the tank outlet, open the tap to allow the water to dis-
place all the air in the hose and then connect to the pressure
washer.
Possible Cause
Plug not connected
Mains socket faulty
Fuse faulty/blown
Extension cable damaged
Motor protector has activated
Frozen
Fuse faulty/blown
Wrong mains voltage
Motor protector has activated
Fuses incorrectly rated
Nozzle partly blocked
Insufficient power supply
Voltage loss due to use of extension cable Check characteristics of extension cable
Appliance not used for a long period of
time
Problems with TSS (Total Stop System)
device
Air in the inlet water supply hose/pump
Inadequate water supply
Water filter blocked
Water supply hoses squeezed
High pressure hose too long
Nozzle worn
Start/stop valve worn
Corrective Action
Connect plug
Use another socket
Replace fuse
Try without extension cable
Allow to cool for 15 minutes
Wait for pump/water supply hose/acces-
sory to thaw
Replace fuse
Check that mains voltage corresponds to
specifications on the model tag
Allow to cool for 15 minutes
Change to a mains supply higher than the
pressure washer amp consumption
Clean nozzle
Check that the voltage of the mains pow-
er supply line is the same as that on the
plate

Allow pressure washer to run with open
spray handle and nozzle at low pressure
until regular working pressure is obtained
Check that the water supply corresponds
to specifications. The minimum specifica-
tion for the water supply hose is 1/2" or
13 mm diameter
Clean water filter
Straighten out kinked water supply hoses
Remove high pressure extension hose.
Retry (extension hose max. 7 m)
Change the nozzle
