Vehicle Immersion
WARNING
Fluids will be ejected through the spark plug hole and may cause serious injury to face
or other body parts. Stand clear of the spark plug while performing the following
steps.
5. Intermittently and briefly touch the starter button in half-second intervals to SLOWLY
rotate the engine three or four times. Water will eject from the spark plug hole.
6. Press and hold the starter button for 10 second intervals for about one minute or until
water vapor is no longer ejecting from the spark plug hole.
7. Check the oil level on the dipstick. If the level is higher than the pre-ride inspection
level, water has entered the oil tank. Do not start the engine. Tow the ATV and see
your dealer. If the oil level is unchanged from the pre-ride inspection level, replace the
spark plug, start the engine and move the ATV promptly to a trailer or towing vehicle.
CAUTION
If water isn't removed promptly from a submerged ATV, rust will form in precision
components, gears, bearings, the cylinder and other areas and result in serious
engine damage. Always see your dealer promptly after an ATV has been submerged.
