Piston and valve casing maintenance
The pistons and valve casings are designed with
very little clearance between each other therefore,
it is very important that these precision parts be
handled with care.
1.
Wrap a cleaning rod with gauze so that no
metal is exposed.

2.
Remove dirt from the inside of the valve cas-
ings.
* In models that are equipped with valve springs
under the valves, remove the springs from the
valve casing before cleaning.
3.
Use the gauze to remove dirt from the pistons.
Th e piston is the most important part of
the instrument. Never treat the pistons
roughly, drop the piston, or let the piston
fall, etc. If the piston becomes damaged or
dented, never return it to the valve casing.
Contact the dealer from whom you pur-
chased the instrument.
4.
After applying valve oil, gently return the pis-
ton to its corresponding valve casing. At this
time, make sure that the valve guide properly
fi ts into the notch.
After fi rmly tightening the valve cap, move the
piston up and down a few times to distribute
the oil evenly.
* Do not apply too much oil.
* Make sure that the number stamped on the valve
casing matches the number stamped on the piston.
