We are proud that you have chosen the
Bombardier Ski-Doo* snowmobile for
your Winter recreational enjoyment and
wish to extend our congratulations
on
your membership into the World's Larg-
est Snowmobiling Fraternity -The Ski-
Doo snowmobilers.
Whichever model you have selected from
the
Nineteen-Seventy-Two Ski-Doa
snowmobile series, you will find that it
has been engineered and designed not
only to introduce today's standards but
so that you, the owner, will benefit of the
knowledge obtained through our policy
of continuous testing and improvement.
As impatient as you may be to try your
new Ski-Doo snowmobile, we strongly
recommend that
you read the entire
Owner's Manual before replacing
it in

This Owner's Manual was prepared to
aquaint you with the operation of the ve-
hicle and to inform you of the routine
maintenance procedures that must
be
periodically upheld.
