It is not necessary to adjust the
carburetor when the unit is new.
Adjust the carburetor only when you
are sure it is necessary due to differ-
ences in working conditions such as
atmospheric pressure or temperature,
or change in unit conditions after
more than 10 hours of use.
If you are unfamiliar with carbure-
tor adjustment techniques, ask your
dealer for advice.
Adjust the carburetor in accor-
dance with the following procedures.
WARNING!
When adjusting the carburetor,
keep bystanders well away, and
make sure the cut-off wheel is
clear of any interference because
the wheel may rotate during
carburetor adjustment.
1. Prior to adjusting, clean the air
filter as described on the previous
page and then run the engine for a
few of minutes at idle speed to
warm up the engine.
