SHARPENING THE LINE

CUTTING BLADE

It is recommended that an OREGON® Service Dealer sharpen the line cutting blade, but it can also be sharpened by the operator.

Line cutting blade sharpening requires a flat file.

After collecting the file, wear gloves and eye protection and remove the battery.

•Lay the trimmer on its side with the line cutting blade on top and face the bottom of the trimmer head (Fig. 33).

•Place the file against the cutting edge of the line cutting blade (1).

•Push the file down and to the right, removing material from the cutting edge (2).
