1-3 Cooling water mixed with beer will be entirely frozen.
Repair leaks and replace cooling water.
2. Beer tap will not move smoothly.
2-1 Valve shaft sliding failure.
2-2 Abrasion powder in spherical lever
bearing.
2-1. Disassemble and clean beer tap. Completely deburr
beer tap. Especially deburr and chamfer edge of
lever insert hole in valve shaft sliding part.
2-2. Remove lever from beer tap to polish spherical
bearing.
