Operating and maintenance notes
8.3 Idle/carburettor adjustment
The cut-off wheel must not rotate when idling!
The idle position must be inspected every time when taking up work and corrected if required.
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:  Chap. 8.4, page 33
Let the engine warm up before performing adjustments.
To set the idle speed indicated in the technical data (chap. 4.6, page 15), proceed as follows – preferably
using a speed meter:
 Idle speed too high (in particular if the cut-off wheel is already driven without throttle):
 Open the idle stop screw "T" counter-clockwise a little.
 Idle speed too low (i.e. the engine goes out with the idling mixture):
 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 the manufacturer.
ENGLISH 32
For correct idle position, the motor should run
smoothly in the idling mixture without driving the
22
cut-off wheel.
The carburettor is preset perfectly at the factory.
Depending on site of deployment, the idle settings
23
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
the manufacturer.
