9.2.3 Fitting/removing the grass trimmer (Fig. 4, 6, 7)
The brush cutter / grass trimmer (12) attachment can be used as a grass
trimmer with the thread coil (16).
• Remove the nut (52), cover (51) and the external flange (50) from the
threaded mandrel (49). Attention - Left-handed thread!
• The nut (52), cover (51) and the external flange (50) are not required
for fitting the thread coil (16) and can be stored in the tool bag (38).
• Hold the internal flange (48) using the Allen key (41) (see Fig. 6)
• Turn the thread coil (16) anti-clockwise on the threaded mandrel (49)
and attach the thread coil (16) hand-tight onto the threaded mandrel
(49).
• Removal of the thread coil (16) takes place in reverse order.
Note that the direction of rotation of the thread coil (16) must match with
the direction of the arrow on the shield (14).
9.3 Assembling the hedge trimmer (17)
The hedge trimmer (17) is already fully assembled.
Attention!
If the hedge trimmer (17) is mounted on the engine drive unit (1), always pull
off the spark plug connector (6) before checking and making adjustments.
9.4 Assembling the pole pruner (26)
Attention!
If the pole pruner (26) is mounted on the engine drive unit (1), always
pull off the spark plug connector (6) before checking and making adjust-
ments.
9.4.1 Installing the blade (32) and the saw chain (31)
(Fig. 8, 9, 10)
• Remove the chain cover (53) by loosening the blade fixing nut (30).
• Screw the chain tensioning screw (55) carefully up to the stop to the
left. This makes it easier to insert the blade (32).
• The saw chain (31) is placed in the circumferential groove of the blade
(32).
• Place the blade (32) with the inserted saw chain (32) into the holder
for the pole-mounted pruner (26). (Fig. 9)
• Pay attention to the alignment of the chain teeth (Fig. 9).
• Guide the saw chain (31) around the chain wheel (54). Make sure that
the teeth of the saw chain (31) grip securely into the chain wheel (54).
• Insert the cutter bar (32) as shown in fig. 9 into the mount at the gear
unit. The cutter bar (32) must be hooked into the chain tensioning bolt
(55a).
• Refit the chain cover (53) and the blade fixing nut (30).
Attention!
Only fully tighten the blade fixing nut (30) after the chain tension has
been adjusted (see section 9.4.2 "Tensioning the saw chain").
9.4.2 Tensioning the saw chain (31) (Fig. 10)
• Loosen the blade fixing nut (30) for the chain cover (53) a few turns.
• Adjust the chain tension with the chain tensioning screw (55). Turn-
ing the screw clockwise increases the chain tension, turning it coun-
terclockwise decreases the chain tension. The saw chain (31) is ten-
sioned correctly when it can be lifted approx. 2 mm in the centre of
the blade (32).
• Retighten the blade fixing nut (30) for the chain cover (53).
• Attention! All chain links of the saw chain (31) must sit properly in the
guide nut of the blade (32).

Notes about tensioning the saw chain (31):
The saw chain (31) must be tensioned correctly in order to guarantee
safe operation. You can identify the optimal tension when the saw chain
(31) can be lifted approx. 2 mm in the centre of the blade (32).
During cutting, the temperature of the chain (31) rises and its length
changes. It is therefore important to check the chain tension at least every
10 minutes and to adjust it again as required. This particularly applies
to new saw chains. Slacken the saw chain (31) after work is complete
because it shortens after cooling down. This prevents the saw chain (31)
from getting damaged.
9.4.3 Filling the automatic saw chain lubrication (Fig. 10)
It is recommended to use standard bio saw chain oil.
• Remove the oil tank cover (56) from the oil tank (29).
• Fill the oil tank (Fig. 29) up to the MAX marking with saw chain oil.
• Close the oil tank cover (56).
9.5 Assembling the extension attachment (22) (31)
• Fit the extension attachment (22) between the motor unit and the
hedge trimmer or the pole pruner. Assembly takes place in the same
way as previously described with the attachments.
Attention!
Do not use the extension attachment (22) in combination
with the brushcutter / grass trimmer (12)!
Note:
Use the extension attachment (22) in order to carry out work at greater
heights.
10. Before commissioning
Never operate the engine drive unit (1) without the brush
cutter / grass trimmer (12), hedge trimmer (17) or pole
pruner (26).
In order to carry out work at height, the hedge trimmer (17) or the pole
pruner (26) in combination with the extension attachment (22) can be
used.
Using the extension attachment (22) in combination with
the brush cutter / grass trimmer (12) is not permitted.
10.1 Attaching the trimmer / grass trimmer (12), hedge
trimmer (17) or pole pruner (26) (following cutting
device) to the engine drive unit (1) (Fig. 11)
• Remove the protective plug (57) to the engine drive unit (1).
• Remove the protective cover (58) from the shaft of the cutting device.
• Slide the shaft of the cutting device into the motor drive unit sleeve (1).
• Gently turn the shaft until the locking pin (13 or 18, 23 or 27) en-
gages.
• Now tighten the locking screw (11 with motor drive unit or 25 with
extension attachment).
Assembly of the extension attachment (22) takes place in
the same way as assembling a cutting device. (Fig. 11)
Hedge trimmer (17) or pole pruner (26) can be mounted on
the extension attachment (22).
• Remove the protection screw (59) from the extension attachment (22).
• Remove the protective cover (58) from the shaft of the cutting device.
