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
.025 "
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.
