ADJUSTING TRIMMER
HEAD ENGAGEMENT
The tension on the drive belt must be
correct for proper operation of the
trimmer head. If the tension is correct,
the trimmer head will rotate when the
Trimmer Head Control Bail is pulled back
against the handlebar (another indication
of correct tension is if the engine stalls
when the trimmer head becomes bound
up in very tough material.)
A worn or loose drive belt will slip on its
pulleys, causing the trimmer head to
move slowly, or not at all, when the con-
trol bail is engaged (belt squealing may
also be noticeable).
If the tension is too tight, the trimmer
AS
head may rotate before the control bail is
100

engaged, or when there is no free play in
the control bail.
