(2) How to mount the workpiece
1. Front mounting
2. Top mounting
！Caution
Use bolt which is shorter than max. thread depth (Max.) by 0.5mm so that the holding bolt for the
workpiece does not hit the guide block. Longer bolts can hit the guide block, which causes operation
failure.

(3) Precautions for mounting
！Caution
①Do not dent and scratch the mounting surface of the body, table and end plate.
Damage can cause reduction in flatness, play at the guide and increase in sliding resistance.
②Do not dent or scratch the rolling surface of the table.
Play or increased sliding resistance can result.
③When attaching the work piece, do not apply strong impact or
large moment.
If an external force more than the allowable moment is applied,
it may cause play at the guide part and an increase in
sliding resistance.
④Keep the flatness of the mounting surface 0.02mm or less.
Insufficient flatness of a work piece or base mounted on the product, the base and other parts can
cause play at the guide unit and an increase in the sliding resistance.
⑤When connecting a load with an external support or guide mechanism, be sure to select a suitable
connection method and perform careful alignment.
⑥Do not touch the product while in operation.
An operator’s finger may get caught between the optional adjuster and product.
Install a cover as a safety measure if an operator can get close to the slide table during operation.
⑦Keep away objects which are affected by magnets.
A magnet is built in the body or, in case of a type with auto switch,
on the side of the guide block. Keep away magnetic discs,
cards or tapes. Data may be erased.
⑧When mounting the air slide table, tighten it with the screws of
appropriate length at the appropriate torque less than
maximum tightening torque.
Tightening to a torque greater than the specified
range may cause malfunction, and insufficient tightening may cause displacement or dropping.
2-2 Air supply
！Warning
①Use clean air.
Do not use compressed air which contains chemicals, synthetic oils containing organic solvents,
salts or corrosive gases, etc., as this can cause damage or malfunction.
！Caution
①Install an air filter.
Install an air filter close to the upstream side of the valve. Choose the filter of 5μm of filtration.
②Install an aftercooler, air dryer or water droplet separator.
Do not use compressed air containing a lot of condensate, which can cause the operating failure
of the product and other pneumatic equipment. Install an aftercooler, air dryer or water droplet
separator.
③Use the product within the specified fluid and ambient temperature range.
When operating at temperatures below 5oC, water in the circuit may freeze and cause breakage of
seals or malfunction. Corrective measures should be taken to prevent freezing.
For compressed air quality, refer to SMC catalog "Compressed Air Purification System".

10
2-3 Piping
！Caution
①Before piping
Before piping, perform air blow (flushing) or cleaning to remove any cutting chips, cutting oil, dust,
etc. from the piping.
②Sealant tape
When installing piping or a fitting into a port,
prevent cutting chips and sealant material from
getting inside the piping.
When a pipe tape is used, leave 1.5 to 2 thread
ridges exposed at the end of the pipe.
2-4. Operating Environment
！Warning
①Do not use in environments where there is a danger of corrosion.
Refer to the construction drawings regarding cylinder materials.
②Install a cover over the rod if it is used in an area that is dusty, or in an environment in which water
or oil splashes on the cylinder.
③When using auto switches, do not operate in an environment with strong magnetic fields.
As this can cause the switch to malfunction.
！Caution
①Do not use in an environment where the product is directly exposed to liquid, such as cutting oils.
If cutting oil, coolant or oil mist splashes the product, play, increased sliding resistance and air
leakage can result.
②Do not use the product in an environment directly exposed to foreign matter such as dust, cutting
chips and spatter.
This can result in play, increased operating resistance, air leakage, etc.
If the product is used in such an environment, contact SMC.
③Shade the sunlight if the product is applied with direct sunshine.
④Shield the product from radiated heat generated by nearby heat sources.
When there is a heat source surrounding the product, the radiated heat from the heat source may
exceed the operating temperature range. Protect it with a cover, etc.
⑤Do not operate in a location subject to vibration or impact.
Contact SMC when using in this kind of location, as damage and operation failure to the fitting can
result.
⑥Do not use the product in applications where excessive external force or impact force is applied to
it.
Malfunction or the damage of the table can result.
Although the table has adequate strength, if it is damaged, protect your hands with gloves.
Hurts can result.
2-5 Lubricating
！Caution
Lubrication of non-lubricating cylinder
The product has been lubricated for life at manufacturer, and does not require lubrication in
service.
If a lubricant is used in the system, use turbine oil Class 1 (with no additive) ISO VG302. Stopping
lubrication later may lead to malfunction because the new lubricant will displace the original lubricant.
Therefore, lubrication must be continued once it has been started.
Wrap this
way.
