Hi-Fax Wear
Check Hi-fax wear by
measuring thickness at
several points along the rail.
Replace Hi-fax when a
thickness of 5/16″ (.8 cm) is
reached (7/16″ on Xtra Lite
models). Take the machine
to your dealer for Hi-fax
replacement.
NOTE: Hi-fax wear patterns
are somewhat different on
XTRA-12 suspensions. The
rear portion will wear rapidly
at first. After this initial
break-in period, the rapid
wear will cease.
If excessive Hi-fax wear
occurs due to poor snow
conditions, additional wheel
kits are available from your
dealer.
