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

1. Precautions for handling the gas spring

This gas spring requires no oil supply to its sliding section. Additional oil will reduce the sealing dura-

bility 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 pressure gas is sealed in it, disassembling it will cause

a high risk.

Note that there is not much rigidity in the bending direction. Depending on accuracy in its installation,

the bending load will cause the rod to bend, resulting in malfunction.

Note that a nick on the piston rod or cylinder will shorten the service life of the sealing or cause a

malfunction.

Do not expose the gas spring to an excessively high or low temperature. The allowable temperature

range for use is -20°C to 80°C.

Avoid using the instrument where it is exposed to to rain, water or much dust.

Do not apply an excessive force to lift the frame end and pull off the gas spring from the leg.

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

G 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.

2. Instructions for discarding the gas spring

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

explosion 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 plastic bag is not used, the oil and drill chips will

spread. (In such a case, wear eye protection

glasses. )
