one screw driver to hold the flange as below and
turn the socket wrench clockwise, the nut will be
released.
• Fit the Nylon cutting head.
Remove another shield after release the nut. Still
hold the flange, take the Nylon cutting head on the
shaft and rotate counter-clockwise, the Nylon cut-
ting head is fitted. Fig. 19
• Release the Nylon cutting head.
Use screw driver to hold flange and then rotate the
Nylon cutting head clockwise, it will be replaced.

• Fit the blade.
• Take the outer flange off after release the nut, then
put the blade (17), outer flange (17b), shield (17a)
and nut according to priority as below picture. Note
the blade rotation direction needs be same as be-
low picture. Use screw driver to hold flange and
tighten nut counter-clockwise, ensure the nut is
tightened 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. Fig. 18
5. Fit the belt. Fig. 13-15
• 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 brush cutter on a hook.
• Hang the machine.
• When standing in a normal working posture, the
blade should touch the ground during normal work-
ing 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 en-
gine 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 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 (see
section 7.1).
7.1 Tensioning the chain (Fig. 45-48)
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. 45).
• Adjust the chain tension with the chain tensioning
screw (Fig. 47/ Item K). Turning the screw clock-
wise increases the chain tension, turning it counter-
clockwise 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 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, slack-
en the chain again as it will shorten when it cools
down. This will help to prevent damage to the chain.
