WARNING
Manual adjustment of automatic slack
adjusters
is a dangerous practice that
could have serious consequences. It
gives the operator a false sense of se-
curity about the effectiveness of the
brakes. Contact the Service Depart-
ment at your dealership if the stroke
exceeds specifications. A stroke ex-
ceeding specifications may indicate a
problem with the slack adjuster or the
brake foundation.
