It is not necessary to adjust the carbu-
retor when the unit is new. Adjust the
carburetor only when you are sure it is
necessary due to differences in work-
ing 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 accordance
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 carbu-
retor 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.
