Prestart Inspection
Always perform a prestart inspection before heading
out on a snowmobile. While the following list may look
exhaustive, it can be performed rather quickly after be-
coming familiar with it.
1. Familiarize yourself with the snowmobile.
2. Clean the windshield with a clean, damp cloth. Do not
use gasoline, solvents or abrasive cleaners.
3. Check track tension (Chapter Three) and adjust if nec-
essary.
4. Check the tether switch and the emergency cut-out
switch for proper operation. If your machine is new or if
you are using a friend's machine, practice using the tether
or stop switch a few times so its use will be automatic dur-
ing an emergency.
5. Check the brake operation. Make sure the brake sys-
tem is correctly adjusted and operates properly,
6. Check the fuel level and fill as needed.
7. Check the injection oil tank. Make sure it is full.
8. Check the coolant level.
9. Operate the throttle lever. It should open and close
smoothly.
10. Open the belt guard and visually inspect the drive
belt. If the belt seems worn or damaged, replace it. Chap-
ter Fourteen lists drive belt wear limit specifications.
Close the belt guard after inspecting the belt. Make sure
the belt guard mounts are not loose or damaged.
11. While the engine shroud is open, visually inspect all
hoses, fittings and parts for looseness or damage. Cheek
the tightness of all bolts and nuts. Tighten as required.
12. Check the handlebar and steering components for
looseness or damage. Do not ride the vehicle if any steer-
ing component is damaged. Tighten loose fasteners as re-
quired.
13. After closing the shroud, make sure the shroud
latches are fastened securely.
