Precautions Regarding the Gas Spring
Please observe the following instructions for proper handling of the gas spring when adjusting the height
of the xylophone stand.
Precautions for Handling the Gas Spring
Do not lubricate. Additional oil on the gas spring will
reduce the durability of the seal and cause oil leakage.
Do not bang on or apply pressure to the gas spring. It
will cause oil leakage, malfunction or breakage.
Do not disassemble. High-pressure gas is sealed inside
the gas spring, so any attempt to disassemble it cre-
ates a high risk of bodily injury.
Do not bend. A poorly balanced load will cause the rod
to bend, resulting in defective operation.
In the event of a failure, stop using the instrument and contact the shop where you pur-
●
chased it. If your dealer is unable to assist you, please contact Yamaha directly as per enclo-
sure.
Instructions for Discarding the Gas Spring
Pressured nitrogen gas is sealed inside the gas spring. Be sure to release the gas before discarding it, or
an explosion may occur, causing injury.
[Caution]
Do not make a hole anywhere in the gas spring
other than in the specified positions (q and w
in the Fig.1).
Do not push.
Do not cut the gas spring.
Do not throw the gas spring into a fire.
[Discarding procedure]
1. Put the gas spring in a plastic bag. Using a drill of 2 to
3 mm, make a hole q from outside of the plastic bag
at the position as specified in the figure to release the
gas and oil and then make a hole w at the position as
specified. (Be sure to make holes in the order of q
and w.)
2. If a vinyl bag is not used, the oil and drill chips will
spread. (In such a case, wear eye protection glasses. )
Do not hit the piston rod or cylinder. A nick in the piston
rod or cylinder will shorten the service life of the seal or
result in defective operation.
Do not expose the gas spring to excessive tempera-
ture. Use the instrument only in temperatures ranging
from -4°F (-20°C) to 122°F (50°C).
Do not apply an excessive force to lift the frame end,
which may pull off the gas spring from the leg, causing
malfunction or breakage.
Do not apply a high-tensile load to the gas spring as it
will cause damage to the gas spring.
