PERIODIC MAINTENANCE 2 - 6
Brake pads
Verify the thickness of the brake pad linings as illustrated. Brake
pads must both be replaced if either one of them shows a
clearance of less than 1 mm (1/32 in.).

NOTICE:
For the replacement of brake fluid, refer to Chapter 10 –
Hydraulic Brake System .
2.6. FRONT SUSPENSION AND SKI
Front fork
The air pressure inside the fork legs must be as close as
possible to atmospheric pressure. Therefore, it is advisable to
remove the bleeder screws
after every ride to re-establish the
pressure. It should be done more frequently when temperature
variations are greater and more frequent (such as when the
vehicle is stored in a heated garage).
A visual inspection of the fork legs can reveal oil leaks that might
indicate broken main seals. If excessive oil is presest on the
lower fork leg, a seal replacement may be required.
It is recommended to replace the fork oil after the break-in
period and, from then on, after every 15 hours of use. For
details, refer to
Chapter 11 – Front Fork and Twin-Axis Ski.
▼
CAUTION
It is advisable to change the fork fluid when preparing the
vehicle for storage. The presence of condensation in the
suspension fluid could cause corrosion during the
storage period.
Twin-Axis Ski and Runners
Verify the torque of all the bolts holding the ski, as well as all the
studs and nuts retaining the runners. Also inspect the
appearance of the runners to detect any wear, distortion, or
broken studs.
