Maintenance
The
steering column support,
relay
rod, outside arms
and
ski columns should all
be ct1ecked
for
tigt1tn~ss
as
often
as
possible. Loosenir1g
and excessive wear of any
of· these items
can cause
poor
handling.
The
steering
column support on the steering gate should be
dis-
assembled
and
lubricated
periodically. The ski
col-
umns
should
be lubricated
with grease every 20 hours.
Lubrication
of al
I other

Maintenance
Tightness

steering linkage
system is
very
ir11portant
in
controlling
parallelisr11
of
the
skis
while the
sr1owmobile is in motion. Skis are
supported on
5
leaf springs that
are
pivoted at the rear
of
the ski
and free to
expand and contract on a wear
plate
at
the front.
part
of the
ski.
This
wear plate
should be greased
often to
reduce friction
between the
spring and wear plate.
