6.4 Practical tips
Never allow the machine to run at low speed for
starting or for cutting.
Cutting for dense growth:
The most e
ff
ective
method is to use wide, sweeping movements,
guiding the cutting edge of the blade straight
through the branches. A slight incline of the blade
downwards towards the movement will produce
best cutting results.
It is recommended to tie a guide line of string or
the like along the hedge so that you cut the hedge
to a level height. The branches above it will be cut
o
ff
. (Fig. 6)
Cutting the side of a hedge:
Cut the sides of
the hedge with curve-shaped movements from
the bottom up. (Fig. 7)
Please note:
As a result of its design, if you work
with the machine on its side for a lengthy period
and the tank not completely
fi
lled, the motor may
stall.
7. Cleaning, maintenance, storage
and ordering of spare parts
7.1 Cleaning
•
Keep all safety devices, air vents and the
motor housing free of dirt and dust as far as
possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low
pressure.
•
We recommend that you clean the device
immediately each time you have finished
using it.
•
Clean the equipment regularly with a moist
cloth and some soft soap. Do not use
cleaning agents or solvents; these could
attack the plastic parts of the equipment. En-
sure that no water can seep into the device.
7.2 Maintenance
Always switch o
ff
the head trimmer and remove
the spark plug boot before carrying out any main-
tenance work.
1. The cutter blades are high quality, made of
tempered steel and in normal use there is no
need to sharpen the blades. If you acciden-
tally strike a wire, stone, glass or other hard
object, this may cause a notch in the blade.
There is no need to remove the notch as long
as it does not adversely a
ff
ect the movement
of the cutting edges. If it does adversely a
ff
ect
this movement, switch o
ff
the machine and
use a
fi
ne
fi
le or a
fi
ne grinding stone to remo-
ve the notch. Ensure that the blade’s cutting
edge is always well oiled (see Fig. 8).
2. If you drop the hedge trimmer, check whether
it has su
ff
ered any damage. If it is damaged
contact an authorized customer service outlet
or send the machine to ISC GmbH to have it
repaired.
3. Only clean the machine after it has been
switched o
ff
. Use only mild soap and a damp
cloth to clean it. Never allow
fl
uid to get into
the machine. Do not use caustic cleaning pro-
ducts.
7.2.1 Maintenance of the air
fi
lter (Fig. 9-11)
Soiled air
fi
lters reduce the engine output by sup-
ply too little air to the carburetor.
Regular checks are therefore essential. The air
fi
lter should be checked after every 25 hours of
use and cleaned if necessary. If the air contains a
lot of dust, the air
fi
lter should be checked more
frequently.
1. Remove the air
fi
lter cover (Fig. 9-10)
2. Remove the
fi
lter element (Fig. 11)
3. Clean the
fi
lter element by tapping it or
blowing it.
4. Assemble in reverse order.
Please note:
Never clean the air
fi
lter with petrol
or in
fl
ammable solvents. Clean the air
fi
lter with
compressed air or by tapping it.
7.2.2 Maintenance of the spark plug
(Fig. 12-14)
Spark plug gap = 0.6 -0.7 mm. Tighten the spark
plug with a torque of 14.7-21.5 Nm.
Check the spark plug for dirt and grime after 10
hours of operation and if necessary clean it with
a copper wire brush. Thereafter service the spark
plug after every 50 hours of operation.
1. Pull
o
ff
the spark plug boot (Fig. 13) by twis-
ting.
2. Remove the spark plug (Fig. 14) with the sup-
plied spark plug wrench.
3. Assemble in reverse order.
