REGULATOR MAINTENANCE
1. Occasionally remove bottom plug (7) and clean valve seat
(11) and body. Clean parts with denatured alcohol, wipe off
seat and blow out body with compressed air.
2. To disassemble regulator, remove screws, bonnet, spring
and spring button. Diaphragm assembly can now be re-
moved.
3. Check all o-rings for signs of damage. Replace if necessary.
4. Reassemble parts. Center stem of valve in hole of regulator
body. Screw bottom plug into body.

dirt in the valve area and cleaning is necessary. If clean-
ing does not correct the problem, replace the items
included in Repair Kit KK-4977. If unit leaks air at A ,
install Repair Kit KK-4977,
