Please observe the following instructions for proper handling of the gas spring.

Precautions for Handling Gas Spring

2. Instructions for discarding the gas

Make sure to observe the following instructions when discarding the gas spring.

As pressurized nitrogen gas is sealed in the gas spring, be sure to release before discarding it. Or an explo-

sion may occur, causing an injury.

[Precautions]

A. Do not crash.

B. Do not cut.

C. Do not make a hole anywhere other than the

specified positions (q and w in the Fig.1).

D. Do not throw it in the 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. )

* Drill 2 holes as shown above to release the

gas before discarding the gas spring.

● Do not apply a high tensile load to the gas spring as it will cause damage to the gas spring.

● In the event of a failure, stop using the instrument and contact the shop of its purchase. If your

dealer is unable to assist you, please contact Yamaha directly.

This gas spring requires no oil supply to its sliding

section. Additional oil will reduce the sealing durability

and cause the oil to leak.

Never apply any impact to the gas spring. It will cause

oil leakage, malfunction or breakage.

Never disassemble the gas spring. As a high pres-

sure gas is sealed in it, disassembling it will cause a

high risk.

The gas spring is not rigid enough to prevent bending

due to unbalanced loads, do not attempt to bend it.

A poorly balanced load will cause the rod to bend, re-

sulting in defective operation.

Caution

Danger

Note that a nick in the piston rod or cylinder will

shorten the service life of the seal or result in defec-

tive operation. Do not hit the piston rod or cylinder.

Do not expose the gas spring to an excessively high

or low temperature. The allowable temperature

range for use is -20°C to 50°C.

Avoid using the instrument where it is exposed to to

rain, water or much dust. It will cause malfunction.

Do not apply an excessive force to lift the frame end

and pull off the gas spring from the leg. It will cause

malfunction or breakage.
