13.8 Mounting the guide bar and tensioning the
saw chain
m ATTENTION
Always carry out assembly with the engine switched
off.
m WARNING
Risk of injury!
Always wear protective gloves when touching the saw
chain (17). Danger of injury due to the sharp cutting
teeth!
Note
A new saw chain (17) stretches and needs to be re-
tensioned more often. Check and adjust the chain ten-
sion regularly after each cut.
Depending on wear, the guide bar (16) can be turned.
• Set the chainsaw down on a level and stable sur-
face.
• Pull the front hand guard (1) back as far as it will go
to release the chain brake (see fig. D).
• Remove the two fixing nuts (20) with the spark plug
wrench / slotted screwdriver (28).
• Remove the chain cover (22).
• Slide the slotted hole of the guide bar (16) over the
two protruding pins.
• Place the saw chain (17) over the teeth of the chain
wheel (26). Insert the saw chain (17) accurately in
the direction indicated on the guide bar (16). In the
tip of the guide bar (16) there is a guide wheel into
whose teeth the saw chain (17) must be inserted.
• Pull slightly on the guide bar (16) to slightly pre-ten-
sion the saw chain (17).
• Fit the chain cover (22) back on. Make sure that the
internal chain tensioning pin (23) fits into the match-
ing hole (25) in the guide bar (16). If necessary, ad-
just the chain tensioning screw (21) with the spark
plug wrench / slotted screwdriver (28).
• Screw on the two fastening nuts (20) by hand. How-
ever, make sure that you do not tighten them yet.
• Use the spark plug wrench / slotted screwdriver
(28) to turn the chain tensioning screw (21) clock-
wise until the lower part of the saw chain (17) slides
into the guide bar (16). The saw chain (17) must be
in contact with the underside of the bar. When the
chain brake is released, it must be possible to pull
the saw chain (17) over the guide bar (16) by hand.
Note
A new saw chain (17) stretches and needs to be re-
tensioned more often.
• Tighten the two fixing nuts (20) with the spark plug
wrench / slotted screwdriver (28).

13.9 Sharpening and maintaining the saw chain
m WARNING
Risk of injury!
Always wear protective gloves when touching the saw
chain (17). Danger of injury due to the sharp cutting
teeth!
Note
An optimally maintained and sharpened saw chain re-
duces physical strain, wear and leads to good cutting
results.
Clean, maintain and sharpen the saw chain regularly.
Check the saw chain regularly for cracks and dam-
aged rivets.
A bench grinder can be attached to the bench grinder
aid (18) for a secure hold during grinding.
Only use special round saw chain files with Ø 4.8 mm
(3/16") for the saw chain included in the scope of de-
livery.
In a sharpening kit, e.g. from Oregon, you will find de-
tailed information on the sharpening process.
Alternatively, use an electric chain sharpener and fol-
low the manufacturer's instructions.
If in doubt about the performance of the work, replace
the saw chain.
If necessary, have the saw chain (17) sharpened by a
specialist workshop.
• Required accessories:
- Round saw chain file Ø 4.8 mm (3/16") (not in-
cluded in the scope of delivery)
- Flat file (not included in the scope of delivery)
- Depth limit gauge (not included in the scope of
delivery)
• File only in forward motion to remove material.
• File with a sharpening angle of approx. 25° at an
incline of 10° to the guide bar (16).
• Check the depth limit distance with a depth limit
gauge.
• The correct distance of the depth limiter should be
0.6 mm (0.024").

13.10 Changing the oil

• Change the engine oil every year before the start of
the season when the engine is warm.
• Use only engine oil (SAE30 / 10W30).
• Open the oil filler screw ( 19).
• Drain the warm engine oil into a drip tray.
• Fill up with engine oil as far as the top mark on the
dipstick (approx. 0.1 l) (see fig. P).
Dispose of the used oil in accordance with appli-
cable regulations.
