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 ﬂ our.

The chain penetrates the wood only under great pressure.

The cutting edge is visibly damaged.

The saw is pulled to the left or right when 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 ﬁ le will be enough.

Have the chain resharpened at a service centre when 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)!

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.

Minimum cutter length is 3 mm (0.11“). Do not resharpen the

chain when the minimum cutter length has been reached; at

this point, the chain must be replaced (see the Extract from the

spare-parts list and „Replacing the 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

0.64 mm (.025“).

CAUTION: Excessive depth

increases the risk of kickback!

All cutters must be sharpened to the same angle, 30°. Different

angles result in a roughly, irregularly running chain, increase

wear and tear and cause chain beakage.

The 85° front rake of the cutter results from the cut depth of

the round ﬁ le. If the proper ﬁ le is used in the right manner, the

correct front rake will be obtained automatically.
