・Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam,
or where there is direct contact with any of these.
・Provide a protective cover if the product is used in direct sunlight.
・Do not operate in environments subject to heavy vibration and/or impact.
・Do not mount the product in locations where it is exposed to radiant heat.
・Install 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.
・When using auto switches, do not operate in an environment with strong magnetic fields.
・Grease oil can decrease depending on the properties of the compressed air used with the
pneumatic equipment, external environment and operating conditions. This may reduce the
lubrication performance and shorten the life of the product.
・Avoid storing the product in humid conditions.
Store the product with the piston rod retracted and avoid humidity, in order to prevent generation of rust.
・Preparation before piping
Before piping, perform air blow (flushing) or cleaning to remove any cutting chips, cutting oil, dust, etc. from
the piping and fittings.
・Winding of sealant tape
When screwing together pipes and fittings , etc., be certain that chips from the pipe threads and sealant do
not get inside the pipe.
Also, when the sealant tape is used , leave approx. 1 thread ridge exposed at the end of the threads.

① Install the lock release solenoid valve as close as possible from the lock unit and keep the piping
length short.
When the piping between the lock unit and solenoid valve is long, delayedlocking or deterioration of stopping
accuracy can result due to the longer overrun.
②
Be aware that repeated supply and exhaust of the solenoid valve for lock may cause condensation.
The lock unit operating stroke is very small and so the pipe is long. If supplying and exhausting air repeatedly,
condensation which occurs by adiabatic expansion, accumulates in the lock unit. This may cause air leakage
and an unlocking malfunction due to corrosion of internal parts.
