Preparing the equipment for use
B) Assembly of the nylon line head
Fig. 7
When fitting a nylon line head, you will not need the
following components shown in Fig. 5:
Retaining nut (28) (caution: left-handed thread), nut
protector (27), pressure washer (26) and metal
cutting blade.
• Fit the anti-winding protection (30) (supplied with
the line head) after the pressure piece (25). The
side of the anti-winding protection labelled with
the number "870" faces the gearbox, so the edge
of the anti-winding protection overlaps the edge of
the bevel gearbox.
• Block the shaft with the pin (29).
• Screw on the line head by hand. Caution: left-
handed thread.
• Fit the protective bar (31) with assembled line
trimmer from underneath onto the guard. Bend
the protective bar slightly in the process.
Important: When using the line head, never
start the brushcutter without the protective bar
and the line trimmer assembled.
If the length of the line has been adjusted (see
chapter 7.5, "Adjusting the cutting line"), the line
trimmer will automatically cut the ends of the line to
the correct length during operation.
When using metal cutting blades, always work
without the protective bar fitted.

Block the shaft with the pin (29) and tighten the nut
(28). Check that the cutting head is securely seated
and properly centred.
Fig. 8d
When using the "Jet-Fit-Flexiblade" cutting head,
always use the standard guard and the assembled
protective bar.
Cutting lines must not touch the guard during rotation.
If necessary, insert the cutting lines slightly further
into the main body of the cutting head. The line
trimmer which is assembled in the protective bar is
not suitable for cutting lines.  The length of the
cutting lines needs to be manually adjusted to the
correct length.
Fig. 8e
Make sure that the
cutting teeth are
correctly aligned in the
direction of rotation.
Various washers are
supplied with the
cutting head.
For installation on this
type of brushcutter, use
exactly the washer
dimensions shown in
the illustration (outer
diameter, inner
diameter).
The lower washer with
an inner diameter of 16
mm must be positioned
around the splines on
the shaft.
Fit the cover of the
cutting head in place,
turn it in the direction of
the arrow and tighten it
with the combination
wrench as shown in the
illustration until it
engages.
To replace a cutting
line, pull the
protruding end back
out from the main
body in the direction
of the arrow (use
universal pliers if
necessary).
