In case of stubborn dirt or sticky filter
fabric:
: Wash filter with STIHL universal
cleaner or in a fresh, non-flammable
solution (e.g. warm soapy water).
: Rinse the filter, from the inside
outward, under a low-pressure
water jet – do not use a high-
pressure washer.
: Dry all parts of the filter. Do not
expose to high temperatures.
: Fit the felt prefilter (1) over the HD
filter (2) - note correct installed
position (see ilustration).
: Install HD filter (with felt prefilter)
and carburetor box cover.
: Check carburetor setting and
readjust if necessary.
The felt prefilter helps protect the HD
filter and thus extends its useful life.
For this reason the felt prefilter should
be replaced at more frequent intervals
than the HD filter.
Always replace a damaged filter.
Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components (e.g.
carburation, ignition, timing and valve or
port timing) without the addition of any
major hardware.
