Changing the air filter element
1. Release the clamps that secure the air filter housing cover.
2. Carefully separate the two halves of the air filter housing.
3. Remove the air filter element from the air filter housing.
4. Wipe the air filter housing and cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter
element edges between the air filter
housing and cover. This could cause
filter damage and allow unfiltered
air to enter the engine if not
properly seated.
6. Replace the air filter housing cover and secure the clamps.
7. Replace the air inlet tube and secure the clamp.
Note:Be sure the hinge features of the air filter cover to the air filter
housing are fully engaged when reassembling the air filter assembly.
Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be voided for any damage to
the engine if the correct air filter element is not used.
