:
Turn the bar over – every time you
sharpen the chain – and every time
you replace the chain – this avoids
one-sided wear, especiallly at nose
and underside of the bar.

Maintaining and Sharpening
Saw Chain
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 and check your chain
for cracks in the links and damaged
rivets – replace any damaged or worn
parts of the chain and match the new
parts to the shape and size of the
original parts.
It is necessary to comply with the
angles and dimensions specified
below. If the saw chain is
incorrectly sharpened – especially
if the depth gauges are too low –
there is an increased risk of
kickback and resulting injury!
