Mounting the guide rail (2) and tensioning
the saw chain (1)
m WARNING
Risk of injury!
Always wear protective gloves when touching the saw chain
(1). Danger of injury due to the sharp cutting teeth!
Only use approved combinations of saw chain (1) and guide
rail (2) (see chapter "Approved cutting gear").
Always carry out assembly with the engine switched off.
Note
A new saw chain (1) stretches and needs to be re-tensioned
more often. Check and adjust the chain tension regularly.
Depending on wear, the guide rail (2) can be turned.
1.
Set the chainsaw down on a level and stable surface.
2.
Pull the front hand guard (3) back up to the stop to re-
lease the chain brake. (Fig. 2)
3.
Remove the two fixing nuts (16) with the spark plug
wrench (20).
4.
Remove the chain cover (17).
5.
Turn the chain tensioning screw (23) (anti-clockwise) un-
til the chain tensioning pin (26) is at the right-hand stop
(Fig. 3). Use the slotted screwdriver (20) for this.
6.
Slide the slotted hole of the guide rail (2) over the two
protruding fastening pins (29).
7.
Place the saw chain (1) over the teeth of the chain wheel
(27). Insert the saw chain (1) accurately into the guide
rail (2). In the tip of the guide rail (2) there is a sprocket
(30) into whose teeth the saw chain (1) must be inserted.
(Fig. 6 and 18)
8.
Pull slightly on the guide rail (2) to slightly pre-tension
the saw chain (1).
9.
Fit the chain cover (17) back on. Make sure that the
internal chain tensioning pin (26) fits into the matching
hole in the guide rail (2). If necessary, adjust the chain
tensioning screw (23) with the slotted screwdriver (20).
10. Screw on the two fastening nuts (16) by hand. However,
make sure that you do not tighten them yet. The fasten-
ing nuts (16) are tightened only after tensioning the saw
chain (1).

Tensioning and checking the saw chain (1)
m WARNING
Put on protective gloves! Danger of injury due to the sharp

1.
Before tensioning, loosen the two fixing nuts (16) a little
with the spark plug wrench (20).
2.
Turn the chain tensioning screw (23) clockwise with the
slotted screwdriver (20) to increase the tension.
3.
Tighten the two fixing nuts (16) with the spark plug
wrench (20).
4.
The saw chain (1) must be in contact with the underside
of the guide rail. Check whether the saw chain (1) can
be pulled over the guide rail (2) by hand (with the chain
brake released, pull the front hand guard (3) back).
