Sharpen the saw chain frequently, without removing much material while doing so. After
sharpening 3 to 4 times yourself, have the saw chain resharpened by a specialist workshop.
This also involves resharpening the depth limiter.
Renew the saw chain as soon as the minimum cutting tooth length of 4 mm (13) is
reached.
IMPORTANT!
Damage to the machine due to incorrect sharpening!
Uneven cutting teeth mean that the chain runs roughly and may even break. All cutting teeth
must have the same length and width after sharpening.
■
Sharpen the saw chain properly.
DANGER!
Danger of fatal injury due to kickback!
The operator can be fatally injured by kickback of the chain saw.
