Working in winter

In order to prevent carburetor icing in conditions of low temper- ature combined with high humidity, and in order to get up to operating temperature faster in subfreezing temperatures, heated air can be taken from the cylinder.

At temperatures above freezing the carburetor must NOT be fed heated air.

Failure to follow these instructions can lead to damage to the cylinder and piston!

1

A

-Remove the filter cover and air filter (see "Cleaning the air filter").

-To enable hot-air induction from the cylinder, remove the plug (A/1) using the universal wrench.

NOTE:

Keep the plug in the saw’s tool kit. You must put the plug back in at temperatures above 0° C / 32° F.

-Reinstall the air filter and filter cover.

B

-The snow filter (B/1, see “Accessories”) prevents the induction of powder snow. It is placed under the prefilter (B/2).

NOTE:

Remove the snow filter before working at temperatures above 0° C (32° F)!

When not in use, store the snow filter in the assembly tool pouch.

MAINTENANCE

Sharpening the saw chain STOP

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 pro- tective gloves!

C

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 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 file will be enough.

Have the chain resharpened at a service center 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: 0.11" (3 mm). 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 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" (chain: 085 / .325") or .030" (chain: 094, 102 / 3/8").

CAUTION:

Excessive depth increases the risk of kickback!
