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 durabil-

ity 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.

Note that there is not much rigidity in the bending di-

rection. Depending on accuracy in its installation, the

bending load will cause the rod to bend, resulting in

malfunction.

● 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.

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 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 speci-

fied 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 posi-

tion 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. )

Precautions for handling gas spring

Caution

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.
