3Com L1 Basic tips, Sharpening settings, see page 12 in the operators 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.
