Remark
The valve is to be replaced when the leakage becomes
more than 1000cc/m at neutral handle position, or more
than 2000cc/m during operation.
This is to be replaced when the sliding surface has
worn more than 10
ҏ
m, compared with the non-sliding
surface.
This is to be replaced when the top end has worn more
than 1mm.
The pin, shaft, and joint of the operating section are to
