Standard setting
To readjust the carburetor, start with
the standard setting:
- Carefully screw down both adjusting
screws until they are hard against
their seats.
Then make the following adjustments:
H = Open high speed screw (1)
1 full turn
L = Open low speed screw (2)
1 full turn
A slight correction may be necessary if
the saw is used at high altitudes
(mountains) or at sea level.
For corrections to high speed
screw (H):
Use a tachometer - do not exceed
max. permissible engine speed.
Engine can be damaged by lack of
lubricant and overheating.
Maximum engine speed with bar and
properly tensioned chain:
12,000 rpm
Note: If no tachometer is available, do
not turn the high speed or low speed
screws beyond the standard setting to
make the mixture leaner.
