5 Mounting the flexible shaft
• Pull the locking bolt out and affix the flexible shaft to
the motor until the locking bolt locks in. Fig. 13, 14
• 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 flex-
ible 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 blade
should touch the ground during normal working posi-
tion.
• 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 un-
doing 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
cover by a few turns (Fig. 52).
• Adjust the chain tension with the chain tension-
ing screw (Fig. 54/ Item K). Turning the screw
clockwise increases the chain tension, turning it
counterclockwise decreases
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 op-
eration. 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 nished
working, slacken the chain again as it will shorten when it
cools down. This will help to prevent damage to the chain.
9. Filling with fuel
m Danger of injury! Fuel is explosive!
Turn the motor off and let the machine cool down.
Wear safety gloves.
Avoid contact with skin and eyes.
Make sure you observe the "Safety Instructions" paragraph.
• Only ever refuel the tool outdoors or in sufficiently ven-
tilated rooms.
• Clean around the filling area. Contaminants in the tank
will cause operating problems.
• Before refuelling, shake the container with the fuel
mixture.
• Carefully open the fuel filler cap (B) so that potential
pressure can be release. Fig. 26
• Carefully pour in the fuel mixture to the lower edge of
the filler.
• Close the fuel filler cap (B). Ensure the fuel filler cap
closes tightly.
• Clean the fuel filler cap and the area around it.
• Check the tank and the fuel line for leaks.
Before starting the motor, remove yourself from the fuel-
ling place by at least three metres.
Draining fuel. Fig. 43
Only ever empty the tank outdoors or in well-ventilated
rooms.
Make sure not to spill fuel or chain oil into the soil (envi-
ronmental protection). Use a proper base.
• Hold a collection container beneath the fuel drain bolt.
• Unscrew the tank cap and remove it.
• Allow the fuel to run out completely.
• Screw the tank cap on firmly by hand.
