4.2 Cutter installation

Always switch off the engine, pull the spark plug cap
and wear protective gloves when fitting or replacing
the cutter!
Depending on your particular model, one of the
following cutting tools will already be provided as
standard equipment with your brushcutter. The
cutting tools described below are available as
genuine SOLO replacement parts which can be
obtained from specialist retailers and should be
installed as described below. Please refer to the
overview of approved accessories in chapter 9 for
more information.
A) Assembly of the 3-tooth brush cutting blade
and the 4-tooth grass cutting blade
Fig. 5
• Position the brushcutter with the output shaft
facing upwards.
• Place the brush cutting blade on the pressure
piece (25). In order to centre the cutting blade, the
shoulder of the pressure piece must be located
exactly in the bore of the cutting blade.
• Fix the pressure washer (26).
• Place the nut protector (27) and turn safety nut
(28) onto the shaft.
Caution! Left hand thread - tighten counter
clockwise.
Take care that all parts are centered.
• Block the shaft with the stop pin (4) and tighten
nut.
It is imperative that the safety nut (28) is
replaced, if it has become loose due to
frequent rem oval and tightening.
Afterwards check that the cutting blade is securely
seated and that it is properly centred.
Preparing the equipment for use
Transport protection for metal cutting blades
When you first purchase an approved metal cutting
blade which is not supplied together with the
brushcutter (see chapter 9 "Accessories"), you will
also need to purchase a corresponding transport
protector.
When the metal cutting blades are attached (4-tooth
grass cutting blade or 3-tooth brush cutting blade,
provided either as standard equipment with the
different models or purchased as accessories), the
transport protector must always be attached to cover
the blades when the device is being stored or
transported, or during work breaks during which the
engine is switched off.
Fig. 6
• Position the transport protector with the
corresponding recess at one of the tips of the
metal cutting blade.
• Press the two tabs (a) on the transport protector
together to increase the internal diameter of the
transport protector.
• Lay the transport protector right over the cutting
tool. Position the inner shoulder (b) between the
metal cutting blade and the running disc.
• Open the two tabs again, and in doing so also
position the inner shoulder between the metal
cutting tool and the running disc at tab (c).
When restarting work, take the transport protector
back off by pressing the two tabs (a) together before
starting the engine.
