hose from machine while system is pressurized. To
depressurize, turn motor off, turn water supply off 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 significantly
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” (Figure 14). 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 off the
unit and let the motor cool.
● Thermal safety has tripped.
- Leave the lance open with water comingthrough.
2. Fluctuating pressure
● Pump sucking air
- 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-
fications. 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
extension cables.
5. The pump does not reach the necessary pressure.
● Water inlet, filter is clogged
- Clean the water inlet filter
● Pump sucking air from connections or hoses
- Check that all supply connections are tight
● Suction/ delivery valves are clogged or worn out.
- Check that the water feedinghose is not leaking
● Unloadervalve is stuck
- Clear or respire valves
● Lance nozzle incorrect or worn out
- Loosen and re-tighten regulation screw.
Check and/ or replace.
PRODUCT FEATURES: WATER SUCKING
FUNCTION.
The Machine could connect to water supply tap, or suck
water from a bucket.
Take the suck hose out of bucket, hold the Nozzle on Low
pressure Postion at first.
Keep the machine running a few seconds to draw-out
surplus water and air in the machine.
Put hose back to water, hold the Nozzle on Low pres -
sure Postion.
Switch it to High pressure Position after water flow a lot
from Nozzle.
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 filters 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.
CLEANING
Keep the ventilation slots of the machine clean to prevent
overheating of the engine. Clean the housing regularly
with a soft cloth, preferably every time it is used. Keep
the air vents free from dust and dirt. Remove stubborn
dirt with a soft rag moistened in soapy water. Do not use
any solvents such as petrol, alcohol, ammonia, etc. as
such substances can damage the plastic parts.
LUBRICATION
The appliance does not need any extra lubrication.
STORAGE AND TRANSPORTATION
Keep the high pressure washer in well-ventilated dry
premises with temperature not going below +5ºC. Oper-
ate the cleaner with non-corrosive/non-toxic antifreeze
before storing for the winter.
FAULTS
If a fault arises through wear in an element, please con-
tact the service address shown on the warranty card. A
drawing of the spare parts that may be obtained is in-
cluded at the end of these operating instructions.
