M aintenance and care
A correctly sharpened saw chain reduces the dan-
ger of kickback and prevents high levels of wear.
Do not work with a blunt or damaged saw chain.
The consequences include physical strain, a poor
cutting result and high levels of chain wear.
The saw chain must be resharpened when saw-
dust is produced during cutting, or if the saw has
difficulty cutting through the wood.
1. Switch off the machine and disconnect the
mains plug.
2. Check the chain tension and adjust it if ne-
cessary.
3. Only use a suitable tool for sharpening:
■ Round chain file 0 = 4.0 mm
■ File guide
■ Chain gauge
■ These tools are available from specialist
retailers.
4. The individual chain links consist of a saw link
(15/3), saw tooth (15/1) and a depth limiter
(15/2).
5. Guide the file from the inside to the outside
of the cutting tooth, exerting slight pressure
and holding it perpendicular (15). A file guide
is helpful for handling the file correctly. 2 - 3
file strokes are sufficient.
6. When sharpening, maintain the angles (15)
on the cutting tooth and the height of the depth
limiter (15/2) in relation to the cutter. Make
sure that all cutting teeth on the chain have
equally length and width after sharpening.
7. If using the prescribed tools and the correct
handling, the specified angle values will be
obtained automatically. The values can be
checked with a chain gauge.
8. At the end, slightly round off the front part of
the depth limiter (15/2).
9. Sharpen the chain frequently, without remo-
ving much material.
10. Renew the saw chain as soon as the mini­
mum cutting tooth length of 4 mm (15) is re-
ached.
11. When the saw chain is sharp, it generates
large and long chips.
After sharpening 3 to 4 times yourself,
have the saw chain resharpened by a
specialist workshop. This also involves
resharpening the depth limiter.

CAUTION!
A
Damage to the machine due to incorrect
sharpening!
Uneven cutting teeth mean that the chain
runs roughly and may even break!
All cutting teeth must have the same
length and width after sharpening.
DANGER!
A
Danger of fatal injury due to kickback!
A saw chain that is not sharpened cor-
rectly can lead to extremely serious inju-
ries!
Sharpen the saw correctly.
Cleaning the in te rio r o f the chain sprocket
Thoroughly clean the chain saw after each use.
1. Disconnect the chain saw from the mains and
place it on a stable base.
2. Unscrew the sprocket cover.
3. Clean the inside with a suitable brush.
4. Remove the saw chain and take out the chain
bar.
5. Clean the groove in the bar and the oil inlet
hole.
Chain bar
Turn over the chain bar after each chain sharpe­
ning and chain change, in order to avoid one-si-
ded wear.
In the EKI 2200/40 and EKS 2400/40
models, it is necessary to change over
the quick-tension chain wheel on the
chain bar before turning. See Changing
over the quick-tension chain wheel.
Regularly check the guide rail for damage. Re­
move any projecting burrs (16).
1. Carefully clean groove in bar (16/1) and oil in­
let hole (16/2).
2. Carefully clean lubricating hole (17/1) from
both sides.
3. Use a suitable grease gun to pump in suffici­
ent grease from both sides in succession until
the grease emerges evenly at the tips of the
sprocket. Keep turning the sprocket when do-
ing this.
Changing over the quick-tension chain wheel
1. Unscrew and remove Phillips screw (18/1).
2. Remove the chain bar, turn it and screw it
back on using Phillips screw (18/1).
