At this time, make sure the valve guide fi ts into
the slot inside the valve casing. After the valve
cap is tightened fi rmly, move the piston up and
down a few times to evenly distribute the oil
over the piston.
* Each piston fi ts into its corresponding casing.
Make sure the number stamped on the piston
matches the number stamped on the casing before
returning the piston into the valve casing.
* Th e pistons must be oiled to function properly
and smoothly.
* As for certain products (YCB-623, etc.), there is
one small hole on the side of each piston to allow
air in the valve case to escape or to maintain the
rotation angle of each piston. Th is is a vent hole
and is not used for lubrication.
