3Com L1 Chainsaw Sharpener User Manual


 
Basic tips:
Cutting angle, see page 8 in the operator's manual. In most cases we
recommend to grind at 60 degrees or from 50 to max 75 degrees. This also
applies if the chain manufacturers recommend other settings.
Sharpening settings, see page 12 in the operator's manual.
The stroke length setting is changed by loosening the wing nut. Now slide the
plate that controls the stroke length so that the front feeder arm falls down
approximately 2 mm behind the cutting tooth to be fed forward. Tighten the
wing nut.
Dressing the grinding wheel, see page 13 in the operator's manual. Before
sharpening the cutting links, dress the periphery of the grinding wheel so it
has an even radius. The grinding wheel must be round before sharpening and
correspond to the round file intended to sharpen the equivalent chain. Check
against the supplied dressing gauge (which also acts as a transport support).
The supplied sprocket weight can ideally be used as a weight on the chain to
stretch it when sharpening. It is beneficial if the chain is slightly “tight”.
This grinder can sharpen most available saw chains, but not 404 chains
designed for logging machines.
Equally long cutting links, see page 9
in the operator's manual (CENTRING
THE GRINDING WHEEL). If the
right and left-hand cutting links are of
different lengths after they have been
sharpened, this is adjusted using the
adjuster screw, 11. When adjusting the
adjuster screw the length of the inner
and outer cutting links decreases
respective increases.
