English

Checking the Chain Sprocket

Disengage the chain brake: Pull the
N
hand guard toward the front handle.
Remove the chain sprocket cover,
N
chain and guide bar.
Replace the chain sprocket
after using two saw chains or
–
sooner
if the wear marks (arrows) on the
–
sprocket are deeper than about
0.02 in (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.
Have the chain sprocket replaced by a
servicing dealer. STIHL recommends
that you have servicing and repair work
carried out exclusively by an authorized
STIHL servicing dealer.
Maintaining and Sharpening
the Saw Chain
Sawing effortlessly with a properly
sharpened saw chain
A properly sharpened saw chain cuts
through wood effortlessly even with very
little pushing.
Never use a dull or damaged saw chain
– this leads to increased physical strain,
increased vibration load, unsatisfactory
cutting results and increased wear.
Clean the saw chain
N
Check the saw chain for cracks and
N
damaged rivets
Replace damaged or worn chain
N
components and adapt these parts
to the remaining parts in terms of
shape and level of wear – rework
accordingly
Carbide-tipped (Duro) saw chains are
especially wear-resistant. For an optimal
sharpening result, STIHL recommends
STIHL servicing dealers.
WARNING
Compliance with the angles and
dimensions listed below is absolutely
necessary. An improperly sharpened
saw chain – especially depth gauges
that are too low – can lead to increased
kickback tendency of the chain saw –
risk of injury!
