Safety Devices On Your Chain Brake; Instructions On Working Properly With The Chainsaw - Ikra IECS 2240 TF Operating Instructions Manual

tension the chain until it can be lifted by around 3 mm in
the middle of the bar, as shown in fig. 5. Now tighten the
thumb screw (7) completely
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 !
4. Connecting the chainsaw (Fig. 7)
We recommend to operate the chainsaw in connec-
tion 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
(house service connection) of max. 0.315 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 outdoor use and are not lighter than rub-
ber-sheathed cables of type H07 RN-F accord-
ing 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 devic-
es for outdoor use should be connected over a
residual current operated device.
To protect the connection cable from strains this chain
saw is equipped with a strain relief. First, connect the
tool's plug with the mains cable. Then, form a tight loop
with the connection cable and put this loop through the
opening on the rear side of the handle. Put the loop over
the strain relief hook as shown in the corresponding
figure. Now the plug-connection is secured against unin-
tentional disconnection.
5. Switching on (Fig. 8 + 9)
• Hold the saw securely with both hands so that the
thumbs and fingers are wrapped around the handle of
the chain saw (Fig. 8).
• Press with your thumbs the stopping button 13 on
the left side of the rear handle and then the operating
switch 9.
• The stopping button 13 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.

Safety devices on your chain brake

1. Chain brake (Fig. 10)
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.
To do this, pull back the hand protection in the di-
rection of the handle.
2. Rundown brake
In accordance with the latest regulations, this chain saw
is equipped with a mechanical rundown brake. This brake
is connected to the chain brake and stops the running
chain after the chain saw has been switched off.
It is activated by releasing the ON/OFF switch. The rundown
brake avoids injuries through the coasting of the chain.
3. Chain catch bolt (Fig. 11)
This chainsaw is fitted with a chain catch bolt (18). If the
chain breaks when the saw is in operation, the chain bolt
will catch the loose chain end and thus prevent injury to
the operator's hand.

chain saw
(Fig. 12 - 19)
CAUTION!
Only saw logs with a diameter less than the saw's
cutting length. Lay people and home users may not
use the plunge cut process to saw and fell trees, as
this causes a kickback on the chain saw and can
therefore result in severe injuries and even death in
certain circumstances.
Always hold the saw with both hands; observe the
safety instructions and figure 8.
Important instructions for cutting and lopping: When
sawing on a slope, always stand uphill from the log
as the log can roll away!
a) Felling a Tree
When bucking and felling operations are being performed
by two or more persons, at the same time, the felling op-
eration should be separated from the bucking operation
by a distance of at least twice the height of the tree being
felled. Trees should be felled in a manner that would en-
danger any person, strike any utility line, the utility com-
pany should be notified immediately.
The chain saw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled.
A retreat path should be planned and cleared as neces-
