Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you

the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do the
work. See Doing Your Own
Service Work on page 10 4.
At your dealer, you can be certain
that you will receive the highest

of genuine parts from your dealer.
