8 Connecting to a water source
So that the water can be drawn in, the height difference
between the high-pressure washer and the water source
must not exceed the max. suction lift (a), @ 19.1.
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-pressure washer.
Connecting the water filter
If the high-pressure washer is operated with water
containing sand from water butts, cisterns or from flowing or
still rivers and lakes, a water filter must be connected to the
high-pressure washer.
Depending on the market, the water filter may be included
with the high-pressure washer.
