trunk is evenly supported as shown in Fig. 19 then pro-
ceed by cutting from the top down. Take care not to cut
into the ground in the process.
If the weight of the tree trunk is resting on one end as
shown in Fig. 20, first cut through 1/3 of the trunk dia -
meter from the underside (A) in order to prevent it from
splintering. Make the second cut from the top (2/3 of the
diameter) to the height of the first cut (B) (this prevents
the chainsaw from being trapped).
If the weight of the tree trunk is resting on both ends
as shown in Fig. 21, first cut through 1/3 of the trunk dia -
meter from the top (A) in order to prevent it from splin-
tering. Make the second cut from underneath (2/3 of the
diameter) to the height of the first cut (B) (this prevents
the chainsaw from being trapped).
When working with the saw on a slope, always positi-
on yourself at a higher point on the slope above the tree
as shown in Fig. 15. In order to retain full control at the
moment when the cut goes through, reduce pressure to-
wards the end of the cut without releasing your firm grip
on the handles of the chainsaw. Take care to ensure that
the chainsaw does not touch the ground. After completing
the cut, wait for the chain saw to come to a standstill be-
fore removing the chainsaw. Always switch off the motor
of the chainsaw before moving from tree to tree.
5.3 Kickback
Danger!
The term “kickback” describes what happens when the
running chainsaw suddenly kicks upward and backward.
Usually, this is caused by contact between the tip of the
cutter rail and the workpiece or the saw chain becoming
trapped. In the event of kickback, large forces occur sud-
denly and violently. As a result, the chainsaw usually re-
acts uncontrollably. This can often result in very serious
injuries to the worker or persons in the vicinity. The risk of
kickback is particularly great when performing cross cuts,
angled cuts and longitudinal cuts, as it is not possible to
use the claw stop on these cuts. You should therefore
avoid these cuts as far as possible and take particular
care when they are unavoidable.
The risk of kickback is at its greatest when the saw is
positioned for a cut in the region of the tip of the cutter
rail, as the leverage effect is greatest there. It is therefore
safest to position the saw flat and as close as possible to
the claw stop before making the cut.
Caution:
●
Make sure that the chain tension is always cor-
rectly adjusted.
●
Only use a chainsaw if it is in perfect working
order.
●
Only work with a saw chain that has been pro-
perly sharpened in accordance with the instruc-
tions.
●
Never operate the saw above shoulder height.
●
Never cut with the upper edge or the tip of the
sword.
●
Always hold the chainsaw firmly with both
hands.
●
Whenever possible, use the claw stop as a le-
verage point.
Cutting wood which is under tension
Special care is required when cutting wood which is un-
der tension. Wood which is under tension from which it is
released by cutting may in some cases react completely
unpredictably and uncontrollably. In the worst case this
could result in extremely severe or even fatal injuries.
This type of work must only be performed by persons
who have been specially trained.
6. Maintenance
6.1 Replacing the saw chain and cutter rail
The cutter rail needs to be replaced if
●
the guide groove of the cutter rail is worn;
●
the nose sprocket in the cutter rail is damaged
or worn.
Proceed as described in the section “Assembly of the
cutter rail and the saw chain”.
6.2 Checking the automatic chain lubrication
You should check the operation of the automatic chain
lubrication system on a regular basis in order to guard
against overheating and the associated damage to the
cutter rail and the saw chain. To do this, point the tip of
the cutter rail towards a smooth surface (board, section
of a cut tree) and allow the chainsaw to run.
