that it goes well down in the crankcase.
Mod. 2036/2040
Tank unit (crankcase)
Dismantle all parts of the chain saw so

Check with compressed air that the oil
tank vent is not blocked. (The oil pump

Pressure equalisation in the tank takes
place via the thread on the screw which
holds the chain guide plate. Make also
sure that the notch under the screw hole
is not filled with dirt.
The fuel tank vent consists of a sintered
filter and of a rubber non return valve.
In order to replace these parts it is
necessary to drill a hole (approx. 3 mm)
in the filter, after which it can be pulled out
by using a steel wire hook. Press in a new
filter in the tank unit.
Replace also the non return valve.
