Sharpening the saw chain
Sharpen the saw chain when:
• Mealysawdustisproducedwhendampwoodis
cut;
• Thechainpenetratesthewoodwithdifculty,even
whenheavypressureisapplied;
• Thecuttingedgeisobviouslydamaged;
• Thesawpullstotheleftorrightinthewood.
(caused by uneven sharpening of the saw chain or
damage to one side only)
Sharpen the saw chain frequently but a little each time.
Twoorthreestrokeswithaleareusuallysufcientfor
routineresharpening.Whenthesawchainhasbeen
resharpened several times, have it sharpened in our

►1. Cutter length 2. Distance between cutting edge
and depth gauge 3. Minimum cutter length (3 mm)
— Allcutterlengthmustbeequal.Differentcutter
lengths prevent the saw chain from running
smoothly and may cause the saw chain to break.
— Do not sharpen the chain when the cutter length
has reached 3 mm or shorter. The chain must be
replaced with new one.
— The chip thickness is determined by the distance
between the depth gauge (round nose) and the
cutting edge.
— The best cutting results are obtained with following
distance between cutting edge and depth gauge.

— The sharpening angle of 30° must be the same on
all cutters. Different cutter angles cause the chain
to run roughly and unevenly, accelerate wear, and
lead to chain breaks.
— Useasuitableroundlesothatthepropersharp-
ening angle is kept against the teeth.
