The file can be guided more easily if a file holder
(accessory) is employed. The file holder has
markings for the correct sharpening angle of 30 °
(align the markings parallel to the saw chain) and
limits the depth of penetration (to 4/5 of the file
diameter).
Guide the file as shown in the figure.

After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional

Chips and sawdust will build up in the guide bar groove,
clogging it and impairing oil flow. Always clean out the
chips and sawdust when sharpening or replacing the
saw chain.
Cleaning the oil filter at the oil discharge hole
Small dust or particles may be built up in the oil filter at
the oil discharge hole during operation.
Small dust or particles built up in the oil filter may impair
the oil discharge flow and cause an insufficient
lubrication on the whole saw chain.
When a poor chain oil delivery occurs at the top of
guide bar, clean the filter as follows.
Remove the battery cartridge from the tool.
Remove the sprocket cover and saw chain from the tool.
