8.5 Fitting/removing the cutting blade (9)
(Fig. 9 - 11)
The brushcutter / grass trimmer (7) attachment can
be used as a trimmer with the cutting blade (9).
1. Remove the nut (i), cover (h) and the external
flange (g) from the threaded mandrel (e). Atten-
tion - Left-handed thread! (Fig. 9)
2. The internal flange (f) remains on the threaded
mandrel (e).
3. Place the cutting blade (9) on the internal flange
(f). Note that the direction of rotation of the cutting
blade (9) must match with the direction of the ar-
row on the shield (16).
4. Then slide the external flange (g) and the cover
(h) onto the threaded mandrel (e).
5. Fasten the cutting blade (9) with the nut (i).
6. Tighten the nut (i) with the assembly tool (26). To
do this, hold the internal flange (f) using the Allen
key size5 (24) (see Fig. 10). .
7. Removal of the cutting blade (9) takes place in re-
verse order.
m Warning!
Please ensure that the trimmer is mounted correctly
before use!
8.6 Attach the carrying strap (12) (Fig. 12 - 15)
• The device must be used with the carrying strap
(12).
• First, balance the machine when the tool is
switched off.
• Put on the carrying strap (12).
• Adjust the length of the belt so that the carabiner
hook (j) is approx. one hand-width beneath the
right hip. Hang the multifunction device on the car-
abiner hook (j).
• Hang and balance the machine.
• The cutting tool (9, 17) may just touch the ground
in the normal working position.
• Hook the device to the carabiner hook (j) of the
carrying strap (12) with the motor running.
• Safety tab (k) on the carrying strap (12).
ATTENTION! In an emergency, the safety tab (k)
on the carrying strap (12) can be pulled. The ma-
chine then immediately detaches from the carrying
strap (12) and falls to the floor.
8.7 Installing the hedge trimmer (8)
(Fig. 26 - 28)
• Remove the screw (l), align the holes (n) so that
they are flush and screw the screw (l) back in.
• Place the cutting unit (15) precisely on the con-
necting rod (8a) (Fig. 26).
• Clamp with screw (m).
• Set the incline using the adjustment lever (14).
Press both unlocking levers (14a) on the hedge
trimmer (8) and adjust to the desired position. (Fig.
28).

• The hedge trimmer (8) can be angled from +90° to
-75° (Fig. 28).
8.8 Installing the chainsaw blade (20) and the saw
chain (19) (Fig. 29 - 30)
1. Remove the chain cover (B) by loosening the fix-
ing nut (A).
2. Screw the chain tensioning screw (C) carefully up
to the stop to the left. This makes it easier to insert
the chainsaw blade (20). (Fig. 30)
3. The saw chain (19) is placed in the circumferential
groove of the chainsaw blade (20).
4. Place the chainsaw blade (20) with the inserted
saw chain (19) into the holder for the pole-mount-
ed pruner (6). (Fig. 30)
5. Pay attention to the alignment of the chain teeth
(Fig. 31).
6. Guide the saw chain (19) around the chain wheel
(E). Make sure that the teeth of the saw chain (19)
grip securely into the chain wheel (E).
7. Place the chainsaw blade (20) into the transmis-
sion retainer (D). The chainsaw blade (20) must
be hooked into the chain tensioning bolt (C).
8. Refit the chain cover (B) and the fixing nut (A).
Attention!
Only fully tighten the fixing nut (A) after the chain
tension has been adjusted (see section 8.8.1 "Ten-
sioning the saw chain").
8.8.1 Tensioning the saw chain (19) (Fig. 32 - 34)
1. Loosen the fixing nut (A) for the chain cover (B) a
few turns using the assembly tool (26).
2. Adjust chain tension with the chain tensioning
screw (C) using the assembly tool (26).
Turning to the right increases the chain tension,
turning to the left decreases the chain tension.
The saw chain (19) is tensioned correctly when
it can be lifted approx. 2 mm in the centre of the
chainsaw blade (20) (Fig. 32).
3. Retighten the fixing nut (A) for the chain cover (B)
with the assembly tool (26).
4. Attention! All chain links of the saw chain (19)
must sit properly in the guide groove of the chain-
saw blade (20).
Notes about tensioning the saw chain (19):
The saw chain (19) must be tensioned correctly in or-
der to guarantee safe operation. You can identify the
optimal tension when the saw chain (19) can be lift-
ed approx. 2 mm in the centre of the chainsaw blade
(20).
Check the chain tension every 10 mins at the latest
and adjust it if necessary as the saw chain (19) heats
up during sawing and therefore its length changes.
This particularly applies to new saw chains.
