may move and cause a fall resulting in injury.
Do not rough play, etc. in the vicinity of the stand. Bodily
harm may result by falling onto the stand. Rough play may
also result in the instrument being overturned. Also, keep

Use the stand’s casters to move the instrument on flat, even

periodic maintenance. Never use thinner, benzene, or other
similar solvents to clean the stand.
If the instrument is frequently moved, the bolts will become
loose over time. Check bolts regularly and firmly tighten any
loose bolts found.
<Regarding the Use of Calf Heads>
As changes in temperature and humidity have a great effect on the tension of calf heads,
please pay attention to the following points.
If possible, tune the head just before playing.
As tension generally lowers when humidity is high, slightly over tune the head.
The head may become warped if the head is loosened when the drum is not in use, so
please make sure head tension is maintained even when the drum is not used.
When mounting (replacing) new calf heads on the drum, first wipe the area of the calf head
that comes in contact with the shell edge using a slightly damp cloth, then mount the head
and tighten the tuning rods equally. Tune the head after it has dried. This procedure im-
proves contact between the calf head and the drum shell.
As long as the tension is not needlessly raised or lowered, the calf head should maintain in
good condition for a long period of time.
