2. Remove the guide bar (16) and the saw chain (17).
3. Measure the groove depth of the chainsaw guide bar
(16) with the scale on a file gauge (not included in
scope of delivery).
4. The chainsaw guide bar (16) must be replaced if any
of the following apply:
– The chainsaw guide bar is damaged.
– The measured groove depth is smaller than the
minimum groove depth of the chainsaw guide bar
(4 mm).
– The groove of the chainsaw guide bar has nar-
rowed or spread.
5. Fit the chainsaw guide bar (16) and saw chain (17) as
described under 8.1.
13.2.2
Checking the sprocket (22) (Fig. 2-5)
1. Turn the screw (18) for the chain tensioning system
anti-clockwise to slacken the chain tension and re-
move the chain cover (21).
2. Remove the guide bar (16) and the saw chain (17).
3. Check the grooving on the chain wheel (22) with a test
gauge (not included in the scope of delivery).
4. If the grooves are deeper than 0.5 mm, do not use the
product and consult a specialist dealer. The chain
wheel (22) must be replaced.
5. Fit the chainsaw guide bar (16) and saw chain (17)
again as described under 8.1.
13.2.3
Replacing the chainsaw guide bar
(16) (Fig. 2, 3)
1. Turn the screw (18) for the chain tensioning system
and the chain cover (21) anti-clockwise to slacken the
chain tension and remove the chain cover (21).
2. Remove the guide bar (16) and the saw chain (17).
3. For dismantling, hold the guide bar (16) swivelled up-
wards at an angle of approx. 45 degrees to make it
easier to remove the saw chain (17) from the groove
of the chainsaw guide bar (16).
4. Replace the chainsaw guide bar (16) and fit the chain-
saw guide bar (16) and saw chain (17) as described
under 8.1.
13.2.4
Replace the saw chain (17) and allow
it to run in (Fig. 2, 3)
DANGER
Serious injuries possible due to tearing or
jumping off of the sawtooth!
–
Never fit a new saw chain on a worn sprocket or on
a damaged or worn guide rail. The saw chain could
jump off or break.
• Only use saw chains and blades designed for this
product.
• Before changing the saw chain, clean the groove of
the guide bar, as the saw chain may jump out of the
bar if it dirty. The deposits can also soak up the chain
oil. The consequence would be that the chain oil does
not reach the underside of the guide bar, or only to a
small extent, and lubrication is reduced.

2. Remove the guide bar (16) and the saw chain (17).
3. Fit the chainsaw guide bar (16) and saw chain (17)
again as described under 8.1.
Note:
With a new saw chain, the tensioning force decreases af-
ter some time. Therefore, you must retension the saw
chain after the first 5 cuts, or after 10 minutes of sawing at
the latest.

WARNING
Increased risk of accidents due to an incor-
rectly sharpened saw chain!
Deviations from the dimensions of the cutting edge ge-
ometry during sharpening increase the risk of kickback
of the product.
–
Have the saw chain sharpened by a professional.
The saw chain can be resharpened at an authorised spe-
cialist workshop. Do not attempt to sharpen the saw chain
yourself if you do not have a suitable tool and the neces-
sary experience.
CAUTION
Special tools are required to sharpen the chain; these
ensure that the cutting tools are sharpened at the cor-
rect angle and to the correct depth.
All cutting links must have the same width and length
after sharpening.
Notes:
A sharp saw chain ensures optimum cutting performance.
It effortlessly eats through the wood, leaving behind large,
long wood chips.
A saw chain is blunt if you have to push the cutting equip-
ment through the wood and the wood chips are very
small. With a very blunt saw chain, no chips are produced
at all, only wood dust.
13.2.5.1
Only use files specifically for saw chains!
Other files have the wrong shape and the wrong edge.
Select the diameter of the file according to your chain
pitch. Be sure to also note the following angles when
sharpening the cutting links.
