Safety Devices On Your Chain Brake; Chain Brake - AL-KO KE 2000/35 Mode D'emploi

KE 2000 / 35 / KE 2200 / 40
• Release and remove the securing nut 7
• Pull off the pinion lid 8
• Lay the saw chains onto the blade and observe the di-
rection of the chain. The cutting teeth must be point-ing
forward on the top of the blade (see fig. 4).
• Lay the unattached end of the saw chain over the chain
drive wheel (see fig.3, B) and the blade 5 with the elongated
hole over the blade guide and chain tensioning bolt
• Observe that the chain tensioning bolt is sitting exactly
in the small opening in the blade (see fig.3, A). It must
be visible through the opening.
• Now shove the blade together with the chain forwards.
Observe that all chain links are positioned exactly in
the blade grove and that the saw chain is running pre-
cisely around the chain drive wheel.
• Replace the pinion lid 8 and press it tightly until secure.
• Replace the securing nut. The securing nut should
initially only be tightened by hand.
• Tighten the chain. To do this, turn the chain tension-
ing screw (see Fig.3, C) in a clockwise direction. The
chain should be tensioned so that it can still be raised
approx. 3 mm in the middle of the blade (Fig. 4).
• Finally, tighten the securing nut 7 using a socket spanner.
KE 2200 / 40
• Put the chain saw on a stable rest.
• Loosen the T-screw 7 turning it clockwise.
• Remove the gear cover 8.
• Put the chain on the bar considering the running direction
of the chain. The cutting teeth on the upper side of the bar
must point in forward direction (see Fig. 4).
• Put the free end of the chain over the chain driving
wheel (B).
• Place the bar such that the long hole in the bar is
placed exactly on the guiding element in the bar seat.
• Take care that the chain tensioning bolt (A) is seated exactly
in the small opening in the bar (Fig. 3). It must be visible
through the opening. If necessary, adjust the knurling wheel
of the chain tensioning device (16) in both directions until the
chain tensioning bolt is seated in the opening in the bar.
• Check whether all chain links are seated exactly in the
bar's groove and the chain is lead around the chain
driving wheel correctly.
• Put the gear cover 8 back on and push it in place.
• Moderately tighten the T-screw 7 by turning it clock-wise.
• Tension the chain. To do so turn the knurling wheel
upwards (+ direction of arrow). The chain should be
tensioned such that it can be lifted by about 3mm in the
middle of the bar (Fig. 4). To decrease the chain tension
turn the knurling wheel downwards (- direction of arrow).
• Finally, tighten the T-screw 7 well by hand.
The tension in the chain has a major effect on the service
life of the cutting fittings, and must therefore be checked
regularly. When the chain warms up to operating
temperature it will expand and must be retightened. A
new saw chain will have to be tightened more frequently
until it has reached its full length.
CAUTION: During the running-in period, the chain
must be more frequently tightened. The chain must
be immediately retightened if it shakes or leaves
the grove !
To tension the chain slightly loosen the T-screw 7. Then
turn the knurling wheel upwards (+ direction of arrow).
Tension the chain such that it can be lifted by about 3mm
in the middle of the bar, as shown in Fig. 4.
3. Connecting the chainsaw (Fig. 5)
We recommend to operate the chain saw in connection
with a residual current operated device with a maximum
breaking current of 30mA.
This device is designed to be operated on a mains supply
with a system impedance Z max at the point of connection
(house service connection) of max. 0.4 Ohm. The user must
ensure that the device is only operated on an electricity supply
system meeting these requirements. If required, system
impedance data may be obtained from the local public utility.
Use only extension cords that are approved for out-
door use and are not lighter than rubber-sheathed
cables of type H07 RN-F according to DIN/VDE 0282
with a diameter of at least 1.5 sq. mm. They cords
must be splash-proof. If the connection cable of
this device should be damaged it must be replaced
by a workshop named by the manufacturer only as
this work requires the use of special tools. Mobile
devices for outdoor use should be connected over
a residual current operated device.
This chainsaw is fitted with a strain-relief device to provide extra
safety for the connection. First connect the device plug with the
connection line. Then form the connection line into a tight loop
and push this through the safety web on the lower side of the
machine. Hang the loop into the hook as shown in Fig. 6. The
plug connection is now secure against automatic release.
4. Switching on (Fig. 2)
• Press with your thumbs the stopping button 15 on the left
side of the rear handle and then the operating switch 9.
• The stopping button 15 is used for unlocking the switch-
on mechanism and does not need to be pressed again
after the device is switched on.
• To switch off the device, release switch 9.
Attention : The sawing chain will start running at
high speed immediately. When putting the saw
down, make sure that the chain never gets in
touch with stones or metal objects.

7. Safety devices on your chain brake

1. Chain brake (Fig. 6)
This chain saw is equipped with a mechanical brake for the
chain. In the case of uncontrolled movements, when the tip
of the sax blade gets in contact with wood or a solid object,
the drive of the chain is immediately stopped by activation of
the hand guard 4, the motor will not be stopped. This brake
function is initiated by the back of your hand on the front
handle 2 pushing the hand guard. The proper function of the
saw chain brake shall be checked before each use of the saw.
CAUTION: No buttons should be pressed when
the chain brake is released (hand protection pulled
back in the direction of the handle and locked).
Always ensure before starting the chainsaw that the
hand protection 4 is locked in the operating position.
