The cylinder and piston are two of the components
which are exposed to the greatest tensions in the
engine. They must withstand high revs, large heat
variations and high pressure. They must also be
resistant to wear. Despite these severe working
conditions serious piston and cylinder malfunc-
tioning is relatively unusual. A contributory factor
to this is the new lining material in the cylinder
barrel, new types of lubricants and refined tech-
nology during the manufacturing.

Dismantling

General

Dismantling work is basically the same for all saw models. In the event that the work
method deviates for a particular model this is given special attention.
Dismantle the following:
Cylinder cover, carburettor cover, chain brake, starter device, plug, air filter, carburettor,
heat shield, pick-up pipe, muffler with heat shield, and on certain models ignition
module, flywheel, oil pump and centrifugal clutch.
See respective section in the Workshop Manual for detailed instructions.
Mod. 2036/2040
Mod. 2041/2045/2050
Dismantle the cables from the short-
circuiting contact and release the screw
which holds the handlebar to the cylinder.
Dismantle the centrifugal clutch and oil
pump.
Remove the cylinder screws and lift off
the cylinder and crankshaft from the
crankcase.

Cleanliness is of extreme importance during
service work on these components. It is therefore
to be recommended that the cylinder and the
surrounding area are well cleaned before the
cylinder is dismantled from the crankcase.
Mod. 2036/2040
Mod. 2041/2045/2050
Dismantle the cables from the short-
circuiting contact and release the screw
which holds the handlebar to the cylinder.
Dismantle the centrifugal clutch and oil
pump.
Lift off the carburettor's adapter with at-
tached ignition module and turbo nozzle.
Remove the screws which hold the cylin-
der attached to the crankcase.
Lift off the cylinder and crankshaft from
the crankcase.
