Precautions to be observed for prevention of product fault or fracture
zSince using an adverse service environment may cause fault, use the product in the environment
described below.
• Place at the following storage temperature range
If the clean-room level of class 4 performance is required
Service temperature: +16°C to +24°C (no condensation at the humidity of 50% or less)
Places other than above
Service temperature: +10°C to +40°C (no condensation at the humidity of 80% or less)
* If you desire to use the product outside of the service temperature range, contact THK.
• Place with non-corrosive gas nor flammable gas
• Place with no dust, salt or metallic powder
• Place where water, oil or chemical can not contact the product
• Place where a vibration or shock does not transmit to the main unit
zPrevent foreign material such as dust or metallic powder from entering the product since it may
cause abnormal wear or shorten the service life.
If foreign material may enter the product, contact THK.
zThe mounting surface for this product must be a machined plane or have accuracy equivalent to
the machined plane. If the surface is insufciently accurate, it may adversely affect the performance
or the service life. In addition, be sure to mount the product on a sufciently rigid base.
zUse the product within the stroke range.
* For more information on the stroke, see the general catalog of the electric actuators.
zBe careful not to let the parts to be mounted on the slider of this product interfere with any other
parts near the stroke end.
zCheck that there is no tool or bolt in the product before operating it.
zThe stoppers attached to both stroke ends of CSKR are not for positioning.Do not use them for
positioning.
zThe standard models contain the THK AFE-CA grease.
zThe photomicro sensors do not have a waterproof or dustproof structure. Do not use it in a place
where much dust or oil mist is present, or where water, oil or chemical directly or indirectly ies.
For other detail information, see the catalog issued by the sensor manufacturer.

6-3 Other precautions
zIf using proximity sensors close to each other, they may interfere with each other. To avoid such
mutual interference, consider taking appropriate measures such as keeping a sufcient distance
between the sensors and using sensors of different frequencies.
For details, see the catalog issued by the sensor manufacturer.
zIf a stainless steel sensor dog is used when a proximity sensor is used, note that the detection
distance is shorter than that of an iron dog.

Failure to do so may cause an unexpected accident.
zWhen handling grease, wear a protective glasses and protective gloves.
If grease gets into eyes or touch the skin, it may affect your body such as causing inflammation.
zDo not apply grease to a ame, rework or high-temperature object.
Doing so may ignite the grease, which could cause fire.
* For other information on handling grease, see the precautions indicated on the grease package or catalog.

Precautions to be observed for prevention of product fault or fracture
zTo have this product fully exerts its functions, it is essential to lubricate the product. Be sure to
supply grease on a regular basis.
Using the product with insufficient lubrication may shorten the service life.
zDo not let foreign material enter the LM guide or ball screw.
Doing so may cause fault, or could adversely affect the performance or service life.
zBe careful not to let foreign material enter between the sealing sheet and cover.
Doing so may cause fault, or could adversely affect the performance.
zWhen you remove the suction joint, be sure to turn off the power supply and stop the supply voltage
rst, and check that uid in the piping has come out.
zAfter mounting, wiring, and pipework, pass uid or connect power supply, and perform an
appropriate function test and leak test. If you nd any leaks or the devices not functioning properly,
do not use the product and make sure that the parts are mounted correctly,
or it may lose the cleaning performance.
zDo not mix different types of greases (uorine, lithium series, etc.)
It may lose the original lubrication performance or generate gas to lose the cleaning performance.
zDo not forcibly press nor damage the sealing sheet when supplying grease.
It may lose the cleaning performance.
zDo not loosen nor remove bolts other than ones specied.
It may cause fault or fracture, or lose the cleaning performance.

7-3 Daily inspection
zBefore operating the product, visually check any exterior damage or stain.
zCheck whether abnormal noise or vibration occurs during operation. If abnormal noise
or vibration occurs, immediately stop the machine and inspect the state of the product.
Check insufficient lubrication or loosening a mounting bolt that can cause abnormal noise or
vibration.
7-4 Periodical inspection
zPerform more detailed inspection approximately once every 3 to 6 months.
•Check the lubrication state, and clean the product and replenish grease.
•Inspect whether or not each mounting bolt is loose, if any of them has loosened, retighten it.
•For the suction joint, check the following and replace it as needed:
1) Scratch, dent, wear, and corrosion
2) Air leaks
3) Twist, crush, or distortion of a tube
4) Hardening, deterioration, or softness of a tube
•Inspect a sealing sheet as follows:
(1) Visually check abnormal wear, scratches, or cracks on the surface of the sealing
sheet.
If you find any abnormalities, replace the sealing sheet.
For the replacement procedure, see “Replacement of sealing sheet procedure.”
(2) Visually check any stains on the sealing sheet.
If you find it extremely dirty, move the slider to the end of each stroke and clean the surface
with a clean waste cloth soaked with ethanol.
Be careful not to strongly press the sealing sheet in cleaning.

zThe standard models contains THK AFE-CA grease before shipment.
See the appendix for the grease specications.
zFor normal operation, replenish grease approximately every 100 km travel distance or 6
months. *See “Method for supplying grease” (The next page).
Note that the greasing interval varies with the service conditions or service environment.
We recommend determining the greasing interval through the initial inspection.
* Note that the greasing interval becomes shorter than usual in case of high-load use or under the
environment where oil content decreases.
zCSKR20 to 33 have a grease nipple PB107, and CSKR46 has a grease nipple A-M6F, as
standard.
