Piston and valve casing maintenance

The pistons and valve casings are designed with

very little clearance between each other there-

fore, it is very important that these precision

parts be handled with care.

Wrap a cleaning rod with gauze so that no

metal is exposed.

Cleaning rod

Gauze

* Exposed metal can damage the instrument.

Remove dirt from the inside of the valve

casings.

* In models that are equipped with valve

springs under the valves, remove the

springs from the valve casing before

cleaning.

Use the gauze to remove dirt from the pistons.

The piston is the most important part of

the instrument. Never treat the pistons

roughly, drop the piston, or let the pis-

ton fall, etc. If the piston becomes dam-

aged or dented, never return it to the

valve casing. Contact the dealer from

whom you purchased the instrument.

Maintenance

After applying valve oil, gently return the

piston to its corresponding valve casing. At

this time, make sure that the valve guide

properly fits into the notch.

After firmly tightening the valve cap, move

the piston up and down a few times to dis-

tribute 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.

●

Rotor and valve casing maintenance

As done before and after playing, apply some

rotor spindle oil to the rotors and valve casing.

Also, apply some lever oil to the lever shaft.
