Caution
Read these instructions before use
1. About these instructions
This manual contains various safety cautions regarding the proper handling of this product, and preventing
danger to the operator as well as damage to the plant and the machine. Please read this manual
thoroughly before using the product.
2. Definition of "Caution"
"Caution" applies to situations in which minor injuries or property damage may result if the operation or maintenance procedures are not strictly followed.
Caution
Do not operate without sufficient mounting strength
- Operating with insufficient mounting strength may damage the main machine and cause injuries
- Ensure sufficient mounting strength of load torque x safety factor
Do not operate without an external stopper
- Use within the damperʼs range of operating angle. Do not use the damper itself as a stopper by setting the
rotational limit position of the rotating shaft as the resting position of the rotating object. Using the damper itself
as a stopper may damage the damper and consequently damage the main machine, and it may also result in
injuries
- Set the external stopper to the operating angle before use.
Do not use when the maximum operating torque is exceeded
- Using this product beyond the maximum operating torque may cause an oil leak, reduced durability, and damage
to the shaft. This may damage the damper and consequently damage the main machine, and it may also result
in injuries. Do not exceed the maximum operating torque when using this product
Do not operate outside the operating temperature range
- Using this product outside the operating temperature range may cause an oil leak and torque problems. Use this
product within the operating temperature range.
Usage enviornment
- This product cannot be used in a vaccum or under high pressure, as this will cause damage to the main
machine.
- Do not use in an environment where chips, cutting oil, water, etc. can come in contact with the linear damper.
This will result in a malfunction due to an oil leak caused by damage.
Do not discard oil more than is necesssary
- Discarding the oil contained in dampers more than is necessary will pollute the environment.
- Dispose the oil according to laws concerning waste management and cleaning.
Radial load to the shaft
- Applying load to the rotating shaft (gear) in a radial direction may cause an oil leak, torque problems, and
damage to the shaft (or to the gear if the gear is used).
Thrust load to the shaft
- Applying load to the rotating shaft (gear) in a thrust direction may cause an oil leak, torque problems, and
damage to the main unit (or to the gear, or cause the gear to become disengaged, if the gear is used).
- When assembling, attach the damper's gear to the opposing arm (gear) as parallel as possible.
Using the product above its maximum rotations
- Using this product above its maximum rotations may cause an oil leak, torque problems, and damage to the
rotating shaft.
- Please refer to the catalogue for the product's maximum rotations.
(*If you are going to exceed the maximum rotations when using this product, please contact our sales
department.)
Using the product outside its operating temperature range
- Using this product outside the operating temperature range may cause an oil leak and torque problems.
- Please refer to the catalogue for the product's operating temperature range.
(*If you are going to use this product outside its operating temperature range, please contact our sales
department.)
Using the product above its maximum cycles
- Using this product above its maximum cycles may cause torque down and an oil leak.
- Please refer to the catalogue for the product's maximum cycles.
(*If you are going to exceed the maximum rotations when using this product, please contact our sales
department.)
Over-tightening of mounting screws
- Over-tightening the mounting screws when installing a rotary damper may cause damage to the main unit.
- Based on the types and sizes of the screws used, please apply an appropriate tightening torque to tighten the
screws.
TK is not responsible for any secondary accidents caused by a rotary damper.
The user should implement preventative measures against such secondary accidents.
