Note the blade rotation direction needs be same as
below picture. Use screw driver to hold flange and
tighten nut counter-clockwise, ensure the nut is tigh-
tened enough.
• Release blade. Use screw driver to hold flange and
release nut, the blade can be took off.
m Warning!
Please make sure the cutting head has been assem-
bled correctly before use!
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 equipment.
The integrated blade (A) in the cutting line guard hood
automatically cuts the line to the optimum length.

5. Fit the belt. Fig. 13-17
• The Combined gasoline grass trimmer, pole saw,
brush cutter must be used with the strap.
• Balance the machine when the tool is switched off.
• Wear the shoulder strap.
• Adjust the strap length so that the snap hook (k) is
about a hand's breadth below the right hip. Hang the
petrol multi-function tool on the karabiner
• Hang the petrol brush cutter on a hook.
• Hang the machine.
• When standing in a normal working posture, the bla-
de should touch the ground during normal working
position.
• Thereby, it is important that the petrol brush cutter is
always well balanced.
• For operation, hook the petrol brush cutter into the
snap hook (k) of the carrying strap while the engine
is running.
• ATTENTION! In an emergency, the safety latch (l)
can be pulled from the harness. The machine then
detaches immediately from the carrying strap (9) and
falls to the ground.
6. Mounting the hedge trimmer Fig. 40-42
• 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 40 on the connecting rod (3).
• Tighten with screw (a).
• Adjust the slope by unlocking the lock (Fig. 41)
• The hedge trimmer can be tilted from 0 ° to 90 °
(Fig.42).
7. Fitting the cutter bar and the chaine (Fig. 43-45)
• Remove the chain wheel cover (Fig. 45/ 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. 44). Insert
the cutter bar as shown in Fig. 44 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
(see section 7.1).
Tensioning the chain (Fig. 45-48)
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. 45).
• Adjust the chain tension with the chain tensioning
screw (Fig. 47/ 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. 46).
• Tighten the fixing screw of the chain wheel cover (Fig.
48).
• 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 midd-
le 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.
8. 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. 19
• 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.
