Checking And Replacing The Chain Sprocket; Maintaining And Sharpening The Saw Chain - Stihl MSE 220 Instruction Manual

English
Checking and Replacing the
Chain Sprocket
Disconnect the plug from the wall
N
outlet.
Remove the chain sprocket cover,
N
chain and guide bar.
Engage the chain brake to lock the
N
chain sprocket – see "Chain Brake".
Replace the chain sprocket
a
after using two saw chains or
–
sooner
if the wear marks (a) on the sprocket
–
are deeper than approx. 0.5 mm
since this would reduce the life of
the chain. You can use a gauge
(special accessory) to check the
depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.

Remove the cup springs (2),
N
washers (3) and sprocket (4).
Install the new chain sprocket in the
N
reverse sequence.
Always mount the chain sprocker with a
new screw (1).
Maintaining and Sharpening
the Saw Chain
1
Cutting effortlessly with a correctly
sharpened chain
2
3
A properly sharpened chain slices
through wood effortlessly and requires
4
very little feed pressure.
3
Do not work with a dull or damaged
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.
Clean the chain.
N
Check the chain for cracks in the
N
links and damaged rivets.
Replace any damaged or worn
N
parts of the chain and match the
new parts to the shape and size of
the original parts.
Carbide-tipped saw chains (Duro) are
particularly wear resistant. STIHL
recommends you have your chain
resharpened by a STIHL servicing
dealer.
It is absolutely essential to comply with
the angles and dimensions specified
below. If the saw chain is incorrectly
sharpened – and in particular if the depth
gauge is set too low – there is a risk of
increased kickback of the saw, with
resulting risk of injury.
