Unit

• Support the snap-action and lever units with one

hand while removing the loosened bolts from the
cover with the other.

• Be careful not to let any parts fall, including

washers and baffle plate.

• Do not tip the snap-action unit, as intake (motive

medium) and exhaust valves may fall off.

• When working with the snap-action unit, take

care not to pinch fingers, etc.

• Reinsert the snap-action unit very

carefully, inserting tips of intake
and exhaust valves into the bottom
of their respective valve seats,
then continuing to insert all the way
up into the valve seats as you
