So that the water can be drawn in, the height dif‐
ference between the high-pressure washer and
the water source must not exceed the max. suc‐
tion lift (a), 18.
The appropriate STIHL suction set must be used.
The suction set includes a water hose with a
special coupling.
Depending on the market, the appropriate STIHL
suction set may be included with the high-pres‐
sure washer.
If the pressure washer is operated with water
that contains sand, dispensed from water butts,
cisterns or from flowing or still rivers and lakes, a
water filter must be connected between the water
hose and the pressure washer.
Depending on the market, the water filter may be
included with the high-pressure washer.
Connecting the Water Hose
► Unscrew the connector (1).
► If a water filter needs to be connected: Screw
the water filter (2) onto the connector (3) and
tighten it by hand.
► Fill the water hose (1) with water so that no air
is present in the water hose any more.
► Screw coupling (2) onto the connector (3) and
tighten by hand.
► Attach the suction cup (4) to the water source
so that the suction cup (4) does not touch the
ground.
► If the spray gun is fitted to the high-pressure
hose: Remove the spray gun.
► Hold the high-pressure hose downwards.
► Switch on the high-pressure washer until an
even water jet flows out of the high-pressure
hose.
► Switch off the high-pressure washer.
► Connect the spray gun to the high-pressure
hose.
► Press and hold down the spray gun trigger.
► Switch on high-pressure washer.
