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 chain 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 se-
curely 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 be-
fore 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 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 re-
quired. This applies in particular to new saw chains.
When you have finished 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" par-
agraph.
• Only ever refuel the tool outdoors or in sufficiently
ventilated 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 poten-
tial 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
fuelling 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 (environmental 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.
10. Start on the unit
Do not start the unit until it has been completely as-
sembled.
m Danger of injury!
Only start the petrol multi garden tool if an at-
tachment is connected! Remove the appropriate
transportation protection and inspect the unit in
good working condition. Never use a damaged,
poorly adjusted or serviced or not completely
and securely assembled device.
