Precautions

Be sure to read this before handling

the products.

Refer to back page 50 for Safety

Instructions and pages 3 to 12 for

Actuator and Auto Switch Precautions.

Selection

Caution

1.

Operate the cylinder until the stroke end.

If the stroke is restricted by the external

stopper and clamp workpiece, effective

cushioning and noise reduction will not be

achieved.

2. Adjust the cushion needles to absorb

the kinetic energy during the cushion

stroke so that excessive kinitic energy

does not remain when the piston reach-

es the stroke end.

If the piston reaches the stroke end with ex-

cessive kinetic energy remaining (more

than the values given in table (1) below)

due to an improper adjustment, excessive

impact will occur, causing damage to ma-

chinery.

1.Keep the adjusting range for the cush-

ion needle between the fully closed

position and the rotations shown below.

Rotations

3 rotations or less

2.5 rotations or less

Use a 3 mm flat head watchmakers screw-

driver to adjust the cushion needles to the

fully closed position, as this will cause dam-

age to the seals. The adjusting range for the

cushion needles must be between the fully

closed position and the open position rang-

es indicated in the table above. A retaining

mechanism prevents the cushion needles

from slipping out; however, they may spring

out during operation if they are rotated be-

yond the ranges shown above.

Precautions for selection standard, mount-

ing, piping, and operating environment are

same as for the standard series.
