MAINTENANCE

Sharpening the saw chain

CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see "Replacing the spark plug"). Always wear protective gloves!

The chain needs sharpening when:

The sawdust produced when sawing damp wood looks like wood flour.

The chain penetrates the wood only under great pressure.

The cutting edge is visibly damaged.

The saw is pulledto the left or rightwhen sawing. This is caused by uneven sharpening of the chain.

Important: Sharpen frequently, but without removing too much metal!

Generally, 2 or 3 strokes of the file will be enough.

Havethe chain resharpenedat a service centrewhen you have already sharpened it yourself several times.

Proper sharpening;

CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)l

All cutters must be of the same length (dimension a). Cutters with different lengths result in rough running of the chain and can cause cracks in the chain.

The minimumcutter length: 0.1l"(3 mm). Do not resharpenthe chain when the minimum cutter length has been reached; at this point, the chain must be replaced (see theLExtractfrom the spare-parts list and "Replacing the saw chain").

The depth of the cut is determined by the difference in height between the depth limiter (round nose) and the cutting edge.

The best results are obtained with a depth-limiter depth of ,025" (0.65 mm).

The sharpening angle of 25"must be identical for all cutters! Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain beakage.

The front rake 60" of the cutter results from the cut depth of the

round file. If the proper file is used in the right manner, the correct front rake will be obtained automatically.
