Air Filter
Removing carburetor box
cover
The
air filter's function is to intercept dust and dirt
in the in-
take air and
thus reduce wear on engine components.
A clogged air filter will reduce the
power
developed by
the
engine, increase fuel consumption and make
starting diffi-
cult.
Clean the air filter daily or more
often if the air is ex-
ceptionally dusty in the work area.
To remove the air
filter, first take off the carburetor box co-
ver by firmly pressing in the twist lock and turning it about
1/4
turn counterclockwise
up
to the detent position. Some
machines have
an integrally molded rib on the twist lock to
indicate its position. When
the rib is vertical (in line with
arrow above the twist lock), the carburetor box cover
may
be pulled
off upward.
Before disassembling
any
further,
clean
away
dirt from ex-
terior of filter and the area around it. Then
use a screw-
driver to unscrew the two slotted nuts.
Pull the
two-part air filter off the
mounting studs. Now
prise
apart the two halves of the filter by inserting
a screw-
driver in the slot provided.
Unscrewing slotted nuts
For daily cleaning it is
sufficient to clean the prefilter
(special
accessory on Wood Boss) and the main filter with
a
natural bristle paint brush. In
addition
to
this
you
should
wash the complete air filter in a
fresh, non-flammable
cleaning solution (lukewarm
soapy water) at least
once a
week and
blow it out with compressed air if possible.
Important:
Flocked
filter elements
must not be
cleaned
with
compressed air, brushes
or rags.
If the wire mesh is damaged in either
half
on the
filter,
replace the
part concerned. It is also important to
ensure
that the choke shutter in
the filter is in good condition.
When refitting the carburetor box cover
make
sure
that the
twist lock is in the
detent position (rib
on
twist lock must
be vertical). The groove on the left-hand side
of the
cover
must engage in the housing guide.
Push the
cover
downward
as
far
as
the stop,
then
press
in
the twist lock
firmly and secure it by turning 1/4 turn
to
the
right (rib on twist lock must be horizontal).
