Operating and maintenance notes

The cutting disc must not be driven when idling!
The idle position must be inspected every time when taking up work and corrected if required.
For correct idle position, the motor should run
smoothly in the idling mixture without driving the
cutting disc.
The carburettor is set perfectly ex works.
Depending on site of deployment, the idle settings
may have to be adjusted via the idle stop
screw "T" (22).
The carburettor adjustment screws "L" (idle mix
control) and "H" (full load mix control) (23) must
only be set by specialist workshops authorised by
us.
Idle stop screw "T"
The idle stop screw "T" can be adjusted with the small screwdriver from the delivery.
The air filter must be clean for correct adjustment. Air filter maintenance:

Let the engine warm up before performing adjustments.
To set the idle speed indicated in the technical data (chap. 4.1, page 11), proceed as follows – preferably
using a speed meter:
•
Idle speed too high (in particular if the cutting disc is already driven without throttle):
è
Open the idle stop screw "T" counter-clockwise a little.
•
Idle speed too low (i.e. the engine goes out with the idling mixture):
è
Close the idle stop screw "T" clockwise a little until the engine runs smoothly with the idling mixture
without going out.
If a perfect carburettor setting cannot be achieved by turning the idle stop screw "T", have the carburettor
set by a specialist workshop authorised by us.
