you thoroughly rinse the surface and that all detergent
has been removed.

WARNING! NEVER disconnect high pressure discharge
hose from machine while system is pressurized. To
depressurize, turn motor o, turn water supply o and
squeeze gun trigger 2-3 times.
5. After each use, wipe all surfaces of the pressure wash-
er with a clean, damp cloth.
6. STORAGE
Do not store pressure washer outdoors.
Do not store pressure washer where it might freeze.
TIPS FOR EXTENDING THE LIFE
OF YOUR PRESSURE WASHER
1. Never operate unit without water.
2. Pressure washer is not meant to pump hot water. Nev-
erconnecttohotwatersupply–thiswillsignicantly
reduce life of the pump.
3. Using detergent other than others brand may cause
damage to pump components (o-rings, etc.).This also
applies to chemicals such as bleach, dish soap, etc.
4. Never operate unit for more than one (1) minute with-
out spraying water. Resulting heat buildup will damage
pump.
5. Before adjusting nozzle’s pressure (high-to-low or low-
to-high) release trigger. Failure to do so will reduce life
of o-rings in lance.
THE SUCTION FUNCTION
You can connect the high pressure cleaner to the water
sources such as taps or pump water from other sources
without pressure.
To work with the water supply without pressure the suc-
tion hose should be removed from the supply and the
gun nozzle should be moved to position “Low” (Figure
14). After that the high pressure cleaner should work idle
for a few seconds to drain the excess water and release
air. Put the suction hose into the water source. After
draining some water the gun nozzle should be moved to
position “High”. Now the high pressure cleaner is ready
to work under high pressure.
TROUBLESHOOTING
1. When switched on, the machine will not start
working.
● Plugisnotwellconnectedorelectricsocketisfaulty.
- Check plug, socket and fuse.
● Themainsvoltageislowerthantheminimumrequire-
ment for start up.
Check that the mains voltage is adequate.
● Thepumpisstuck.
- Refer to after storage instructions. Switch o the
unit and let the motor cool.
● Thermalsafetyhastripped.
- Leavethelanceopenwithwatercomingthrough.
2. Fluctuating pressure

- Check that hoses and connections are airtight
● Valvesdirty,wornoutorstuck.Pumpsealsworn.
- Clean and replace or refer to dealer.
3. Water leaking from the pump
● Sealswornout
- Check and replace, or refer to dealer
4. The motor stops suddenly
● Thermalsafetyswitchhastrippedduetooverheating.
- Check that the mains voltage corresponds to speci-
cations.An extension cable, which is too thin, and
tool long can cause a voltage drop and cause the mo-
tortooverheat.Leavetocooldown.Useheavyduty

5. SERVICE & MAINTENANCE
WARNING! Unplug the electric cable (power
source) prior to any maintenance or prepara-
tory storage operations.
Make sure that the machine is not live when carrying out
maintenance work on the motor.
● To ensure good performance, check and clean the
suction and detergent lters after every 50 hours of
operation.
● Longperiods ofdisuse mayleadto theformation of
lime scale deposits. Working through the hole on the
rear, RELEASE the motor using a screwdriver (for
models with this feature).
Then remove the screwdriver and proceed with the
restart operations.
