Front Shell, Port and Port Ring

Inspection. Before installing the Front Shell, Port Ring and Port, visually inspect
the o-rings for dirt or other foreign matter that may compromise the seals. Do the
same with the Front Shell face (where the Front Shell mates) and Port bore where
the o-rings seal. See the separate document "Housing Care and Maintenance
Guide" for more details.
 NOTE: Some lenses do not require a Port Ring. Refer to Gates Lens Compatibility
Matrix for details.
 CAUTION: Do Not lubricate the orange Front Bulkhead o-ring. It is silicone
material and lubricant may cause damage. Only the BLACK and YELLOW o-rings
are safe to lubricate.
Retract the ND Filter Control.
Install the Front Shell. Position the Port Extender over the entire lens / LGD's and
secure to the front bulkhead with 4 screws. Tighten the 4 screws firmly. Push in
and test the ND filter control mates smoothly and freely.
