Cleaning the cooling system
Clean the vents on the outer area of the pressure washer with
a damp cloth. In order to ensure that the air-cooling system
works property while in operation, do not allow the vents to
clog.
Never clean the pressure washer directly with the jet
spray. Unplug the mains plug before beginning
to clean!
WARNING NOTICE:
Avoid allowing water to permeate through the vents of the
pressure washer to minimise the risk of electric shock or dam-
age to the unit.

L
Remove the spray wand from the hand spray gun (fig. L-5).
Clean dirt from the nozzle opening using the nozzle cleaner
provided (fig. L-8).
Storing the high pressure hose
The high-pressure hose must be wound up on the hose reel
after using the pressure washer. The original rolling direction
should be maintained (fig. M).
The hose is damaged each time it is wound against the rolling
direction. To avoid winding the hose in the wrong direction,
the rolling direction can be marked on the hose reel using a
u-formed pin (fig. M-16)

Cleaning the water filter
The pressure washer le equipped with a water inlet filter to
protect the pump (sea fig. E-6).
To clean the internal water filter, remove the garden hose con-
nector and dismount the filter from the pump inlet.
Rinse with water in the reverse direction to clean the filter.
Ra-insert the filter and garden hose connector to prevent for-
eign particles from entering into the pump.
If the filter is not cleaned, the water flow in the pressure wash-
er la reduced and the pump becomes damaged.
Be careful not to damage the filter when removing or cleaning
it. Any foreign particles that enter the pump can damage it.
Cleaning the housing
Use clear water to clean the housing and a soft cloth to dry it.
Harsh detergents are not recommended.
CAuTION Only work on the unit when it is turned off
and unplugged.
