7.5 Information regarding the line head
(available as accessory)
When using the nylon head, always ensure that you
operate only with the correct length of line. When the
contact shield is fitted, the line will always be
trimmed to the permissible length automatically (a
line trimming blade is fitted into the shield). There is
a high risk of injury, and the engine is subjected to
excessive loads leading to a risk of damage, if nylon
lines are left too long.
Therefore, when converting the cutting tool from
grass cutter blade to nylon head, always fit the
standard contact shield together with the protective
bar and fitted line trimming blade.
Adjusting the cutting line
When using a semi-automatic nylon head:
Fig. 16
(schematic diagram)
Whilst the brushcutter is running without load, but
with rotating nylon head, lightly push the nylon head
several times onto ground with growth cover. The
cutting line will be dispensed in stages. With each
action, approx. 30 mm line will be dispensed. The
line trimming blade will correct any excess length.
When the cutting line is fully spent, you can replace it
with line available Ø 2,4 mm under part no. 6900942
or Ø 3,0 mm part no. 6900974 (accessory).

8. Operating and maintenance instructions

8.1 General operating and maintenance
instructions
The maintenance and the repair of modern machines
as well as their safety-relevant assemblies require
qualified specialised training and a workshop
equipped with special tools and test equipment.
Consequently the manufacturer recommends that all
tasks not described in these operating instructions be
carried out by a specialised workshop. That
specialist has the required training, experience, and
equipment at his disposal, to provide you with the
most cost-effective solution for such work. He will
provide additional help in word and deed.
After a running-in time of app. 5 hours, all accessible
screws and nuts (except the carburettor adjusting
screws) must be checked for tightness and they must
be retightened, if required.
Using your brushcutter; Operating and maintenance instructions
Check the cutter regularly and whenever you notice
any irregularities, or when the cutter/contact shield
becomes blocked. For this, switch off the engine and
wait until the cutter has come to a complete standstill.
Pull the spark plug cap, and remove grass, debris,
etc. from the cutter support. Immediately replace
blunt or damaged tools, even if they display only
small cracks – do a "ping" test.
It is best to store the equipment in a dry, safe location
with a full fuel tank. There should be no open flame or
similar nearby. For longer periods without using the
equipment (longer than four weeks), see chapter "9.8
Shutdown and storage".

8.2 Gearbox lubrication

To lubricate the bevel gear drive, use SOLO "Special
gearbox grease" (part no. 008318025). Check the
grease level weekly and top up, if required (approx.
every 20 - 50 hours).
Fig. 17
Remove the filler plug from the side of the gearbox. If
no grease is visible inside, top up with grease (top-up
quantity approx. 5 – 10 g).
Replace and tighten the filler plug.
Please note: Do not overfill with grease, as that may
lead to the gearbox overheating. Never fill the
gearbox casing to the top with grease.
Tip: If required, top up with a maximum of 5g grease.
It is preferable to check more frequently (e.g. before
you start working) whether grease is still visible.
Your SOLO dealer workshop is happy to help you in
case of doubt.
