Caution

5. Vibration

When vibrations are applied on impact objects, implement a secure

guide on impact objects.

Warning

1. Before performing installation, removal, or stroke adjustment,

make sure to cut the power supply to the equipment and verify

that the equipment has stopped.

2. Installation of protective cover

We recommend the protective cover should be installed in the case

workers might be getting close during the operation.

3. The rigidity of the mounting frame

The mounting frame must have sufficient rigidity.

Load on mounting plate can be calculated as follows.

Depending on the impact conditions, a load applied to the mounting

frame may exceed the calculated value.

When setting the rigidity of the mounting frame, the sufficient safety

ration must be taken into account in the calculated value.

Caution

1. Tightening torque of mounting nut should be as follows.

When threading on a mounting frame in order to mount a shock

absorber directly, prepared hole dimensions are referred to the table

below.

For tightening torque of a nut for shock absorber, kindly abide by the

table below.

If the tightening torque that is applied to the nut exceeds the value

given below, the shock absorber itself could become damaged.

Caution

2. Deviation of impact

The installation must be designed so that the impact body is

perpendicular to the shock absorber's axial center. An angle of

deviation that exceeds 3

° will place an excessive load on the bearings,

leading to oil leaks within a short period of operation.

3. Rotating angle

If rotating impacts are involved, the installation must be designed so

that the direction in which the load is applied is perpendicular to the

shock absorber’s axial center. The allowable rotating angle until the

stroke end must be

4. Do not scratch the sliding portion of the piston rod or the outside

threads of the outer tube.

Failure to observe this precaution could scratch or gouge the sliding

potion of the piston rod, or damage the seals, which could lead to oil

leakage and malfunction. Furthermore, damage to outside threaded

portion of the outer tube could prevent the shock absorber from being

mounted onto the frame, or its internal components could deform,

leading to a malfunction.

5. Never turn the screw on the bottom of the body.

This is not an adjusting screw. Turning it could result in oil leakage.
