and counter hexagonal nut again wi
th
second wrench.
Thereafter assemble air finer and filter cover again.
In extreme cases (failure of automatic oil pump, heavy
frost etc.) the use of the hand oiler assures sufficient chain
lubrication.
Also during longer cutting periods with longer cutting
lengths the chain
is additionally supplied with lubricating
all by activating the manual oller. Moreover, before
starting
we
recommend to supply
add~lonal
lubricating oil to bar
and chain by activating the manuai olier should the saw
s~
idle at freezing temperatures for a longer period. Thus the
cutting attachment is protected against excessive wear.
The oil level can be-checked at the inspection window
(3).
Always fill up with chain oil before starting work. Check
the oil level at frequent intervals during cutting and top
~
30 up before it drops too low.
Air Filter
Di
sassembty
of
air
filter
The air filter's function is to intercept dust and dirt
in
the
combustion air and thus reduce wear on engine compo-
nents.
Clogged air
Mers
reduce engine power, increase fuel
consumption and make starting more difficun.
The
airfilter
must
be
cleaned
dally-or
morefrequently
in
very
dusty
operating
conditions.
Before removing the finer, close the choke vaive so that
no
dirt can get Into the carburetor. Unscrew the finer cover
and take
out
the
filter element.
For daily cleaning it is sufficient
to clean the filter with a
soft brush. However,
the
complete' air fitter should
be
washed In clean gasoline at least once a week
and
blown
out with compressed air
IT
possible (Hocked air filters must
not
be
cleaned with compressed air, brushes or rags
).
If
the wire mesh is damaged on either hart of the air finer
(or
If
the fiocking is damaged), always fit a new part.
It
is advisable to carry a spare filter with you at ali
Umes
and clean the dirty finer in the workshop.
