Files and how to work with them

Sharpen using a special file holder with a saw chain round file. Normal round files are not appropriate for this work. See "Accessories" for the order number.

099:File the first cutter half with a 7/32" (5.5 mm) dia. round saw-chain file, then switch to a 3/16" (4.8 mm) dia. file.

496:Filethe cutter with a 7/32" (5.5 mm) dia. round saw-chain

file.

The file should cut only when pushed forwards (arrow). Lift the file when leading it backwards.

First sharpen the shortest cutter. The length of this cutter is then the standerd for all other cutters of the chain.

New saw teeth must be filed to the exact same shape as the used teeth, including on their running surfaces.

Always guide the file horizontally ( 9 0 to the guide bar).

.-

The file holder makes file guidance easier. It is marked for the correct sharpening angle of 25" (keep the marks parallel with the chain when filing, see illustration) and limits the cut depth to the correct4/5 of the file diameter. See "Accessories" for the order number.

After havingsharpenedthe chain, the heightof the depth limiter must be checked by means of a chain gauge. See "Accesso- ries" for the order number.

Correct even the smallest excess height with a special flat file (1). See "Accessories" for the order number.

Round off the front of the depth limiter (2).
