CAUTION
An incorrectly installed saw chain leads to uncontrolled
cutting behaviour by the product!
When fitting the saw chain, observe the prescribed run-
ning direction!
1. Turn the fastening nut (36) anti-clockwise, so that the
chain wheel cover (37) is removed. Use the open-end
spanner AF 8/10mm (C).
2. Turn the chain tensioning screw (38) anti-clockwise to
loosen the chain tension. Use the installation spanner
(D).
3. Lay out the saw chain (15) in a loop so that the cutting
edges are aligned clockwise. To align the saw chain
(15), follow the symbols (arrows) above the chain
wheel (41).
4. Place the saw chain (15) in the groove of the chain-
saw guide bar (14).
5. Guide the saw chain (15) around the chain wheel (41)
and check the alignment of the saw chain (15).
Make sure that the teeth of the saw chain (15) engage
securely in the chain wheel (41).
6. Insert the chainsaw guide bar (14) on the guide pin
(39) and the chain tensioning bolt (40). The guide pin
(39) must be in the elongated hole and the chain ten-
sioning bolt (40) must be in the lower hole on the
chain guide (14).
7. Fit the chain cover (37) back on.
8. Tighten the fastening nut (36) clockwise hand-tight.
9. Recheck the seating of the saw chain (15) and tension
the saw chain as described under 9.6.
Note:
Only tighten the fastening nut once the chain tension has
been set.

Tensioning the saw chain (15)
(Fig. 1, 10, 13, 14)
WARNING
Risk of injury from the saw chain jumping off!
An insufficiently tensioned saw chain can come off
during operation and cause injuries.
–
Check the saw chain tension frequently.
–
The chain tension is too low if the drive links come
out of the groove on the underside of the guide rail.
–
Adjust the tension of the saw chain properly if the
saw chain tension is too low.
1. Loosen the fastening nut (36) by a few turns using the
open-end spanner AF 8/10mm (C).
2. Set the chain tension using the chain tensioning screw
(38).
Use the installation spanner (D).
– Clockwise - increases the chain tension
– Anti-clockwise - reduces the chain tension
The saw chain (15) must not sag, although it should be
possible to pull it 1-2 millimetres away from the chainsaw
guide bar (14) in the centre of the chainsaw guide bar
(14).

1. Turn the saw chain (15) by hand, to check it runs free-
ly. It must glide freely in the chainsaw guide bar (14).
2. Re-tighten the fastening nut (36).
The saw chain is correctly tensioned when it does not sag
on the chainsaw guide bar and can be pulled all the way
round with a gloved hand. When pulling on the saw chain
with 9 N (approx. 1 kg) tractive force, the saw chain and
chainsaw guide bar must not be more than 2 mm apart.
Note:
• The tension of a new chain must be checked after a
few minutes in operation, and adjusted if necessary.
• The tensioning of the saw chain should be carried out
in a clean place free from sawdust and the like.
• Correct tensioning of the saw chain is for the safety of
the user and reduces or prevents wear and chain
damage.
• We recommend that the user check the chain tension
before starting work for the first time. The saw chain is
correctly tensioned when it does not sag on the under-
side of the guide bar and can be pulled all the way
round with a gloved hand.
ATTENTION
When working with the saw, the saw chain heats up
and expands slightly as a result. This "stretching" is to
be expected especially with new saw chains.
10 Operation
ATTENTION
Always make sure the product is fully assembled
before commissioning!
WARNING
Danger of injury!
The on/off switch and the safety switch must not be
locked!
–
Do not work with the product if the switches are
damaged. The on/off switch and the safety switch
must switch off the product when released.
–
Make sure the product is in working order before
each use.
WARNING
Electric shock and damage to the product
possible!
Contact with a live cable during cutting can result in
electric shock. Cutting into foreign objects can cause
damage to the cutter bar.
–
Scan hedges and bushes for hidden objects, such
as live wires, wire fences and plant supports, before
cutting
ATTENTION
Make sure that the ambient temperature does not ex-
ceed 50°C and does not fall below -20°C during work.
