Hi my name's Brae Grimes and I'm the product and repair specialist for the
band and orchestral department of the Yamaha Music Australia and today we're
talking about trombones although trombones look quite simple
there's a lot that can go wrong very quickly if you don't know how to handle
them and maintain them properly a lot of damage can be done
unlike other brass instruments trombones come in two pieces so we have to attach
the slide to the bell section and then put it in the mouthpiece when we take
the trombone out of the case it's usually bell section first then the
slide when we're assembling the slide and when we're taking it out of the case
we want to make sure that the lock is on so we pop the slide into the receiver
here and twist it around to playing position we want to make sure that we
don't go further than that just in case the slide knocks on the Bell then
holding it as if we are going to play it we thread on the screw and do it up
fairly tight a common misconception with the trombone
is that we put lubricant all over the inner slide to make it work properly
however what we want to do is coat the outer slide on the inside with lubricant
to do this we apply a generous amount of lubricant of your choice on the stocking
of the slide that's this part here it's usually a little wider than the rest of
the inner tube we work it into the slide by running it up and down and coating
the inside of the slide once we've done that we want to remove excess lubricant
from the slide then apply water to the inner slide using a spray bottle
after playing I recommend using a Yamaha trombone slide swab to remove excess
moisture from the inner slide make sure you shake out the swab before running it
through the slide as this can sometimes get stuck if it's bunched up together
remember to remove water using the water key after you play as part of monthly or
quarterly maintenance I recommend exchanging the tuning slide
grease and cleaning the slide remove old grease using a lint-free cloth reapply
grease by putting a ring on the raw brass part of the slide
and then clean off the excess using a cloth or cotton tip
your trombone comes with a cleaning rod and polishing gauze this is only to be used for the outer
slide when removing excess lubricant to wrap your cleaning rod pull a corner of
the gauze through the eye of the rod over the end and wrap it around like this
I like to use a little bit of dry cleaning fluid whether that be
methylated spirits or shellite or something similar to remove the excess
lubricant from the inside of the outer slide once I've done this I'll relubricate
the slide and put it back in its case if your slide doesn't quite feel right it
could be that it's got a twist a bend or sometimes there's a tiny little dent in
the outer slide to get this repaired take it to your local service technician
as available on our website as with any brass instrument it's important not to
force stuck components apart for more information please visit our website
