It is very difficult to sharpen a saw chain correctly
without the right equipment. Zenoah recommends that
you use our file gauge. This will help you obtain the

WARNING: Departure from the sharpening
instructions considerably increases the risk
of kickback.
Note: See instructions under

of the cutting teeth is reduced to 4 mm (5/32") the
saw chain is worn out and should be replaced.
