Checking And Replacing The Chain Sprocket; Maintaining And Sharpening The Saw Chain - Stihl HTE 60 Instruction Manual

Checking and Replacing
the Chain Sprocket
Remove the chain sprocket cover,
N
chain and guide bar.
Replace the chain sprocket
a
– after using two saw chains or
sooner
– if the wear marks (a) on the sprocket
are deeper than 0.5 mm – the life of
the chain would otherwise be
reduced. Use reference 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 chain sprockets.

Maintaining and
Sharpening the Saw Chain
Cutting effortlessly with a correctly
sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
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 an increased
risk of kickback, with resulting risk
of injury.
The saw chain cannot be locked in place
on the guide bar. Therefore, it is best to
remove the chain from the bar and
resharpen it on a workshop sharpening
tool (FG 2, HOS, USG).
