grinder 272S are maintained correctly. The
air filter units on these models have there-
fore been included in this workshop manual.
268K, 272K and 272S
The prefilter is an oiled foam filter which is
easily accessible under the filter cover (A).
In dusty conditions this filter should be
checked/replaced after every second
refuelling.
The filter should be cleaned and oiled regu-
larly to obtain maximum filtration efficiency.
Cleaning
Dismantle the filter. Wash the filter in warm
soapy water. After cleaning, rinse the filter
thoroughly in clean water. Squeeze and let
the filter dry.
NOTE!
Compressed air at a high pressure can
damage the foam.
Oiling
Oil the filter carefully. It is extremely impor-
tant that the entire filter is saturated with oil.
Use HUSQVARNA oil no. 503 4773-01. The
bottle holds 0.1l, which is sufficient for three
applications.
