Foreword
This
manual
is designed
primarily
for
use by
snow-
mobile mechanics in a properly equipped shop.

it
contains enough detail and basic

formation

mainte-
nance and repair
work
. A basic knowledge
of
mechanics, the proper use
of
tools, and workshop
procedures
must
be understood in order to carry

has
insufficient
experience
or
doubts his ability to do the work, the adjustments,
maintenance, and repair

out
only
by qualified mechanics.
In order to perform the
work
efficiently
and to
avoid costly mistakes, the mechanic should read
the
text, thoroughly familiarize
himself
with
the
procedures before starting work, and
then
do
the
work
carefully in a clean area.
Whenever
special
tools
or
equ ipment is specified, makeshift tools or
equipment
should
not
be used. Precision measure-
ments
can only
be
made
if
the proper
instruments
are used, and the use
of
substitute tools may
adversely affect safe operation
of
the
snowmobile.
Whenever
you see
the

shown
below, heed
their
instructions I
Always
