 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.

Wrap a cleaning rod with gauze so that no

metal is exposed.

Cleaning rod

Gauze

* Exposed metal can damage the instrument.

Maintenance

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.

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.

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.
