instructions
9.1 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.
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 "9.9 Shutdown and storage".
9.2 The starter
The following instructions are aimed at increasing
the service life of the starter rope and of the starter
mechanism - see also chapter "7 Starting / Stopping
the engine":
• Always pull the rope out in a straight line.
• Do not let the rope drag across the edge of the
rope eyelet.
• Do not pull rope all the way out - risk of the rope
breaking.
• Always manually guide the rope back into its
start position with your hand on the starter grip -
do not let it retract on its own.
A specialist can replace a damaged starter rope.

9.3 Gearbox lubrication
To lubricate the bevel gear drive, use SOLO "Special
gearbox grease" (part no. 0083180). Check the
grease level weekly and top up, if required (approx.
every 20 - 50 hours).
Fig. 16
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.
9.4 Carburettor adjustment
The carburettor has been adjusted optimally at the
factory. Subject to the operational altitude
(mountains or low lying areas), the carburettor may
require readjustment.
