OPERATION
WARNING: Sometimes branches or grass get caught
between the guard and cutting attachment. Always
stop the engine before cleaning.
Check before starting
• Check the blade to ensure that no cracks have formed at the
bottom of the teeth or by the centre hole. Discard a blade if
cracks are found (Fig. 48).
• Check that the support flange is not cracked due to fatigue or
due to being tightened too much. Discard the support flange if
it is cracked (Fig. 49).
• Ensure the locking nut has not lost its captive force. The
tightening torque of the locking nut should be 18.4 ftlb (25 Nm).
(Fig. 49)
• Check that the blade guard is not damaged or cracked. Replace
the blade guard if it is cracked (Fig. 50).
• Check that the trimmer head and trimmer guard are not
damaged or cracked. Replace the trimmer head or trimmer
guard if they have been cracked (Fig. 50).
WARNING: Never use the machine without a guard or
with a defective guard.
WARNING: The complete clutch cover and shaft must
be fitted before the machine is started, otherwise the
clutch can come loose and cause personal injury.
Ensure the cutting attachment cannot come into
contact with any object. Make sure no unauthorised
persons are in the working area, otherwise there is a
risk of serious personal injury. The safety distance is
50 ft (15 metres).
Working methods
WARNING: Avoid cutting with the area of the blade
between the 12 o’clock and 3 o’clock positions.
Because of the speed of rotation of the blade kickout
can occur if you attempt to cut thick stems with this
area of the blade.
Forestry clearing
• Before you start clearing, check the clearing area, the type of
terrain, the slope of the ground, whether there are stones,
hollows etc.
• Start at whichever end of the area is easiest, and clear an open
space from which to work.
• Work systematically to and fro across the area, clearing a width
of around 13-16 ft (4-5 m) on each pass. This exploits the full
reach of the machine in both directions and gives the operator
a convenient and varied working area to work in.
• Clear a strip around 250 ft (75 m) long. Move your fuel can as
work progresses.
• On sloping ground you should work along the slope. It is much
easier to work along a slope than it is to work up and down it.
• You should plan the strip so that you avoid going over ditches
or other obstacles on the ground. You should also orient the
strip to take advantage of wind conditions, so that cleared
stems fall in the cleared area of the stand.
