Square-Ground Filing

FILE DIRECTION

Oregon

recommends that

square-ground chain be filed

from the outside in (in a down-

ward direction). This leaves a

better edge on the chromed

cutting surfaces and makes it

easier to keep the file’s posi-

tion, and the resulting cutting

edges, in correct alignment as shown in the preceding

“File Positioning” section. However, filing from the out-

side in will wear out your file faster.

Some square-ground chain users may prefer to file from

the inside out (in an upward direction). You should be

aware that inside-out filing is much more difficult.

But whichever direction you choose, be sure your file

and your cutting edges stay positioned as shown in the

preceding “File Positioning” section. File all cutters on

one side of the chain, then reverse the chain and repeat

the process. Use the same file positions for cutters on

the opposite side of the chain.

TOOLS

Only use files specially designed for square-ground

chisel cutters, available from your chainsaw dealer.
