MAINTENANCE
SKI SKAGS
WARNING
Worn skis and/or skags will adversely affect handling. Loss of vehicle control
may result, causing serious injury or death. See your dealer's studding chart
for recommended skags.
Check skags before each use of the snow bike to ensure positive steering
characteristics. Skags must be replaced when worn to half their original
diameter.
TIP
Carbide skags must be replaced if any abnormal wear or chipping is found.
SKAG REPLACEMENT
1. Raise and support the front of the snow bike so the ski is approximately 6
inches (15.2 cm) from the ground.
2. Remove the attaching nuts and pry the skag downward.
3. Remove the front end of the skag.
4. Remove the rear end of the skag.
5. Reverse the steps to install a skag.
RAIL SLIDE WEAR
Timbersled rail slides run along the
bottom of the rail to prevent track wear.
The rail slide should be inspected
periodically and replaced when
necessary.
For ease of inspection, all Timbersled
rail slides have a wear limit indicator
w
groove to indicate the minimum
q
permissible slide thickness .
Replace the rail slides if they are worn
to the top of the groove at any point
along their length. Failure to do so may
result in permanent damage to the
track or rails.
