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 fitted 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. 13-17
• 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 multi­function tool on the karabiner
• 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
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 chain
(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).
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 coun -
terclockwise 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.
