• Remove the nut (42), cover (41) and the external
flange (40) from the threaded mandrel (39). Atten-
tion - Left-handed thread!
• The nut (42), cover (41) and the external flange (40)
are not required for fitting the thread coil (16).
• Hold the internal flange (38) using the Allen key
size 4 (31) (see Fig. 6)
• Turn the thread coil (16) anti-clockwise on the
threaded mandrel (39) and attach the thread coil
(16) hand-tight onto the threaded mandrel (39).
• Removal of the thread coil (16) takes place in re-
verse order.
Note that the direction of rotation of the thread coil
(16) must match with the direction of the arrow on the
shield (14).
8.3 Assembling the hedge trimmer (17)
The hedge trimmer (17) is already fully assembled.
Attention!
If the hedge trimmer (17) is mounted to the engine
drive unit (1), always remove the spark plug connec-
tor (6) before checking and adjustment work.
8.4 Assembling the pole-mounted pruner (21)
Attention!
If the pole-mounted pruner (21) is mounted to the
engine drive unit (1), always remove the spark plug
connector (6) before checking and adjustment work.
8.4.1 Installing the guide bar (26) and the saw
chain (25) (Fig. 8, 9, 10)
• Remove the chain cover (43) by loosening the
guide bar fixing nut (24).
• Screw the chain tensioning screw (45) carefully up
to the stop to the left. This makes it easier to insert
the guide bar (26).
• The saw chain (25) is placed in the circumferential
groove of the blade (26).
• Place the guide bar (26) with the inserted saw chain
(25) into the holder for the pole-mounted pruner
(21). (Fig. 9)
• Pay attention to the alignment of the chain teeth
(Fig. 9).
• Guide the saw chain (25) around the chain wheel
(44). Make sure that the teeth of the saw chain (25)
grip securely into the chain wheel (44).
• Place the guide bar (26), as shown in figure 9, into
the transmission retainer. The guide bar (26) must
be hooked into the chain tensioning bolt (45a).
• Refit the chain cover (43) and the guide bar fixing
nut (24).
Attention!
Only fully tighten the guide bar fixing nut (24) after
the chain tension has been adjusted (see section
8.4.2 "Tensioning the saw chain").
8.4.2 Tensioning the saw chain (25) (Fig. 10)
• Loosen the guide bar fixing nut (24) for the chain
cover (43) a few turns.
• Adjust the chain tension with the chain tensioning
screw (45). Turning anti-clockwise increases the
chain tension, turning anti-clockwise reduces the
chain tension. The saw chain (25) is tensioned cor-
rectly when it can be lifted approx. 2 mm in the cen-
tre of the guide bar (26).
• Retighten the guide bar fixing nut (24) for the chain
cover (43).
• Attention! All chain links of the saw chain (25) must
sit properly in the guide groove of the guide bar
(26).
Notes about tensioning the saw chain (25):
The saw chain (25) must be tensioned correctly in or-
der to guarantee safe operation. You can identify the
optimal tension when the saw chain (25) can be lifted
approx. 2 mm in the centre of the guide bar (26).
Check the chain tension every 10 mins at the latest
and adjust it if necessary as the saw chain (25) heats
up during sawing and therefore its length changes.
This is especially true for new saw chains.
Slacken the saw chain (25) after work is complete be-
cause it shortens after cooling down. This prevents
the saw chain (25) from getting damaged.
8.4.3 Filling the automatic saw chain lubrication
(Fig. 10)
It is recommended to use standard bio saw chain oil.
• Remove the oil tank cap (46) from the oil tank (23).
• Fill the oil tank (Fig. 23) up to the MAX marking with
saw chain oil.
• Close the oil tank cap (46).
Attention! Oil is very easily flammable. Avoid smok-
ing, naked flames or flying sparks near oil.
9. Before commissioning
m Attention!
Always make sure the product is fully assembled
before commissioning!
Never operate the engine drive unit (1) without
the brush cutter / grass trimmer (13), hedge trim-
mer (17) or pole-mounted pruner (21).
9.1 Attaching the brush cutter / grass trimmer
(13), hedge trimmer (17) or pole-mounted
pruner (21) (following cutting device) to the
engine drive unit (1) (Fig. 11)
• Remove the protective cover from the shaft of the
cutting device.
• Pull the unlocking pin (11) and push the shaft of the
cutting device into the sleeve of the engine drive
unit (1).
