1. Place the chain saw on a stable base.
2. Pull hand guard (3/1) in the direction of the
arrow in order to release the chain brake.
3. Unscrew fastening nut (3/2) and remove the
sprocket cover.
4. Turn chain tensioning screw (3/3) to the left as
far as the stop. Tensioning hook (3/4) is then
located at the end of the stop, in the direction
of chain sprocket (4/3).
5. Place the chain bar on guide pin (4/1) and
push sufficiently far in the direction of chain
sprocket (4/3) until tensioning hook (3/4) fits
in the hole in chain bar (4/2).

1. Pull hand guard (5/1) in the direction of the
arrow in order to release the chain brake.
2. Unscrew clamping nut (5/2) and remove the
cover.
3. Turn the chain tensioning disc on the loose
chain bar (6/2) fully to the right.
4. Place the chain bar on the threaded pin (6/1).
5. Turn the chain tensioning disc as far as possi-
ble to the left so that chain bar (6/2) is moved
in the direction of chain sprocket (6/3).
Installing the saw chain
EKS 2000/35
Note the running direction of the saw
chain. The cutters of the saw teeth on
the upper side of the chain bar point for-
wards towards tip of bar (4).
1. Place the saw chain on chain sprocket (4/3)
and in the groove of the chain bar.
2. Following this, guide the saw chain around the
reversing sprocket of the chain bar.
3. The saw chain hangs down slightly on the un-
derside of the chain bar.
4. Turn chain tensioning screw (7/1) a little to the
right until the saw chain makes contact with
the underside of the chain bar.
5. Put on the sprocket cover and tighten fasten­
ing nut (3/2) until finger tight.
When tightening chain tensioning screw
(7/1), make sure that tensioning hook
(3/4) does not slide out of hole (4/2) in
the chain bar.
EKI 2200/40 and EKS 2400/40

2. Following this, guide the saw chain around the
reversing sprocket of the chain bar.
3. The saw chain hangs down slightly on the un-
derside of the chain bar.
4. Put on the sprocket cover and tighten clam­
ping nut (5/2) slightly.
Tightening the saw chain
EKS 2000/35
1. Check the seat of the saw chain so that it
sits correctly on the chain sprocket and in the
chain bar.
2. Lift the chain bar at the reversing sprocket and
turn chain tensioning screw (7/1) clockwise
until the saw chain is in contact with the un-
derside of the bar.
3. Tighten fastening nut (3/2).
The saw chain has been tensioned cor-
rectly when it can be lifted by approx. 3 -
1
4 mm in the middle of the chain bar and
can be pulled though by hand.
EKI 2200/40 and EKS 2400/40
1. Check the seat of the saw chain so that it
sits correctly on the chain sprocket and in the
chain bar.
2. Turn clamping ring (8/2) to the right in order
to tension the chain.
3. Tighten clamping nut (8/1).
Checking the chain tension
Frequently check the chain tension, because new
saw chains stretch.
The saw chain has been tensioned correctly
when:
■ It is in contact with the underside of the chain
bar and can be pulled through by hand
■ It can be lifted by 3 - 4 mm in the middle of
the chain bar
At operating temperature, the saw chain stretches
and hangs down.
CAUTION!
A
Danger of injury due to the saw chain
jumping off!
Incorrect tensioning of the saw chain can
lead to injuries!
Drive links are not allowed to come out of
the groove on the underside of the chain
bar. Re-tension the saw chain.
