9.3 Gearbox lubrication

Fig. 15
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).
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.

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.
If the idle speed is correctly adjusted, the engine
should run on idle, without the cutter moving. Slight
adjustments of the idle throttle into the average idle
speed given in the specification can be made via the
idle stop screw "T" by following the instructions below
(the use of a tachometer is recommended):

The air filter must be clean to ensure correct idle speed
adjustment. Let the engine run until it is warm, before
making any adjustments.
!
If the engine idles too fast (in particular if the power
tool has already operated at idle speed), turn the
idle speed stop screw "T" anti-clockwise.
!
If the engine idles too slowly (i.e. the engine always
dies in idle), turn the idle speed stop screw "T"
clockwise a little, until the engine runs smoothly.
Under no circumstances must the cutter be
driven at idle speed.
Only qualified mechanics must adjust the
regulating screws for idle mixture "L" and full load
mixture "H".
If the idling speed cannot be set correctly with the idling
end-stop screw "T", request an authorised service
centre to tune the carburettor.
The following instructions are for authorised
service shops
D-CUT carburettors:
Use the D-CUT carburettor key to adjust the idle
mixture screw "L" and the full load mixture screw "H".
Check with our customer service team regarding the
basic setting.
Carburettors with limiter caps:
The regulating screws for idle mixture and full load
mixture can only be adjusted in a limited range.
The carburettor is tuned for optimum engine
performance. Use a rev counter to tune the
carburettor correctly!
Do not adjust the engine to a higher speed. Excessive
engine speed can lead to major engine damage!
