• Open the air filter cover, screw the accelerator cable
in as shown and attach to the throttle valve. Fig. 15-
17
• Secure with a counter nut. The accelerator cable
must be able to move from idle to full acceleration
freely. Fig. 18
• Connect the ignition interruption cables as shown in
figure 19 + 20.
• Secure the air filter cover with a screw again. Fig. 21
• Remove the screw from the handle, insert the other
side of the flexible shaft into the handle and use the
screw to affix it to the handle. Fig. 22 + 23
• Use cable ties to affix the accelerator cable to the
flexible shaft. Fig. 24
6. Fit the belt. Fig. 56 - 60
• Wear the shoulder strap. Fig. 56 - 58
• Balance the machine when the tool is switched off.
• When standing in a normal working posture, the bla-
de should touch the ground during normal working
position.
• To fit the backpacks to your body size adjust the
straps at the carrying strap. Fig. 59
• Safety button at the carrying strap Fig. 60
ATTENTION! In an emergency, the safety button (m)
can be pressed from the harness. The machine then
detaches immediately from the carrying strap and
falls to the ground.
7. Mounting the hedge trimmer (Fig. 47-49)
• Remove the screw (d), align the holes (c) so that they are
flush and screw the screw (d) back in.
• Place the hedge trimmer (15) precisely as shown in
Figure 47 on the connecting rod (3).
• Tighten with screw (a).
• Adjust the slope by unlocking the lock (Fig. 48)
• The hedge trimmer can be tilted from 0 ° to 90 °
(Fig.49).
8. Fitting the cutter bar and the chaine (Fig. 50 - 52)
• Remove the chain wheel cover (Fig. 52/ Item J) by
undoing the fastening nut (Item I). Lay the chain (Item
F) as shown into the groove which runs around the
cutter bar (Item E).
• Note the alignment of the chain teeth (Fig. 51). Insert
the cutter bar as shown in Fig. 51 into the mount at the
gear unit.
• Place the chain round the chain wheel (Item H). Make
sure that the teeth of the chain engage securely in the
chain wheel. The cutter bar must be hooked into the
chain tensioning bolt (Item G).
• Fit the chain wheel cover
Important! Do not fully tighten the fastening screw
until after you have adjusted the chain tension.
Tensioning the chain (Fig. 52 - 55)
Important! Always pull out the spark boot plug before
performing any checks or adjustments.
• Undo the fastening screw (Item I) of the chain wheel
34 GB
cover by a few turns (Fig. 52).
• Adjust the chain tension with the chain tensioning
screw (Fig. 54/ Item K). Turning the screw clockwise
increases the chain tension, turning it counterclockwi-
se decreases the chain tension.
The chain is correctly tensioned if it can be raised by
around 2 mm in the middle of the cutter bar (Fig. 53).
• Tighten the fixing screw of the chain wheel cover (Fig.
55).
• Important! All the chain links must lie properly in the
guide groove of the cutter bar.
Notes on tensioning the chain:
The chain must be properly tensioned to ensure safe
operation. When the saw chain can be raised by around
2 mm in the middle of the cutter bar, you know that the
chain tension is ideal. During cutting, the temperature
of the chain rises and its length changes. It is important
therefore to check the chain tension at least every 10
minutes and to adjust it again as required. This applies
in particular to new saw chains. When you have fi ni-
shed working, slacken the chain again as it will shorten
when it cools down. This will help to prevent damage to
the chain.
OPERATION
When working with the equipment as grass trimmer
and brush cutter, the appropriate plastic guard hood
for cutting blade mode or cutting line mode must be fi
tted to prevent objects being thrown out by the equip-
ment.
The integrated blade (A) in the cutting line guard hood
automatically cuts the line to the optimum length.
