■ Applying Oil To The Valve Slides
1.
Depress the piston that corresponds to the slide
that you want to apply oil and partially remove
the slide. Apply a few drops of tuning slide oil.
* Do not apply too much oil.
2.
Hold the piston down and move the slide in
and out a few times.
3rd valve
* If you remove or replace the valve slide without
holding the piston down, the drop or buildup
of air pressure in the pipe can cause poor piston
function or damage to the inside of the pipe.
* The pistons must be oiled for them to function
properly and smoothly.
After applying slide oil to valve slides equipped
with a spring type slide trigger, hold the piston
down and move the slide in and out a few times
as you did before to distribute the oil evenly.
■ CAUTION —Preventing The 3rd
Valve Slide From Falling Off.
On instruments fitted with a stopper screw,
make sure the screw is tight.

making removal difficult.
About the slide stopper
Some instruments are supplied with a
silicon Yamaha Slide Stopper to prevent ac-
cidental removal of the tuning slides. The
stopper can be left in place when playing
and used in other configurations as shown
below.
