Square-Ground Filing
GULLET FILING
Approximately every 5th sharpening, clean out gullets
by filing them back with a 7/32" round file. File gullets
from the inside out (the side opposite from sharpening).
Always leave a 1/8" shelf behind the gullet.
BEFORE AFTER
If not cleaned out regularly, the outer edge of your gul-
lets will eventually prevent the working corners of your
cutters from getting an adequate bite into the wood.
DEPTH-GAUGE SETTING
The depth-gauge setting for all square-ground
chisel chain is .025."
NOTE
WWrroonngg
Little or no clearance
between the working corner
and the gullet’s outer edge.
RRiigghhtt
Clearance is maintained
between the working corner
and the gullet’s outer edge.
