Product Usage Instructions

Installation

Remove the top of the sealing grease and cut the tip off using snips, just past the threads. This will allow the tube to lay a sufficient bead of grease onto the filter.
Hold the base of the filter upside down and apply an even bead of grease between the two bump seals and around the base of the filter (refer to Fig. 1).
With the filter top and wing bolt together, align the wing bolt into the post inside of the air box.
Once threads are started, insert and snap the top into the base and begin tightening the filter.
Do not tighten completely. Move the filter around a bit to ensure it is sealed properly.
Once seated, tighten the wing bolt until secure.

Note: These instructions must be followed every time the filter is serviced. Failure to do so may result in the filter not sealing properly, which could lead to damage to the engine.
