Working in winter

In order to prevent carburetor icing in conditions of low tem‑

perature 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 (marking (circled) on

insert in "snowake" position).

At temperatures above freezing the carburetor must NOT be fed

heated air (marking (circled) on insert in "sun" position).

Failure to follow these instructions can lead to damage to

the cylinder and piston!

‑ Remove the lter cover (

B/1).

‑ Position the universal wrench (

B/2) as shown above and

push the insert (B/3) out by tapping the wrench.

‑ Put the insert (

B/3) back in in the appropriate position, i.e.

with the marking next to the sun symbol for normal operation

or the snowake symbol for subfreezing operation.

‑ Replace lter cover (

B/1).

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protec-

tive gloves!

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. 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

0.65 mm (.025").

CAUTION:

Excessive depth increases

the risk of kickback!

subfreezing operation

normal operation

The chain needs sharpening when:

‑ The sawdust produced when sawing damp wood looks like

wood 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 le will be enough.

Have the chain resharpened at a service centre when you

have already sharpened it yourself several times.
