○ Adjust the depth gauge to the specifi ed setting.
Failure to observe the above raises the possibility of a kickback
and may result in injury.
1) If you sharpen your cutters with a fi le holder, check and lower the
depth.
2) Check depth gauges every third sharpening.
3) Place depth gauge tool on cutter. If depth gauge projects, fi le
it level with the top of the tool. Always fi le from the inside of the
chain toward an outside cutter. (Fig. 43)
4) Round off front corner to maintain original shape of depth gauge
after using depth gauge tool. Always follow the recommended
depth gauge setting found in the maintenance or operator
manual for your chain saw. (Fig. 44)
