Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and
other debris from inside the pipe.
2. Wrapping of sealant tape
When screwing together pipes and fittings, etc., be certain
that chips from the pipe threads and sealing material do not
get inside the piping.
Also, when sealant tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the threads.

1. Lubrication of non-lube type cylinder
The cylinder is lubricated at the factory and can be used
without any further lubrication.
However, in the event that it will be lubricated, use class 1
turbine oil (with no additives) ISO VG32.
Stopping lubrication later may lead to malfunction due to the
loss of the original lubricant. Therefore, lubrication must be
continued once it has been started.

Caution
Air Supply
1. Use clean air.
Do not use compressed air that includes chemicals, synthetic
oils containing organic solvents, salt or corrosive gases, etc.,
as it can cause damage or malfunction.
1. Install air filters.
Install air filters at the upstream side of valves. The filtration
degree should be 5
µ
m or finer.
2. Install an air dryer, after-cooler or water
separator, etc.
Air that includes excessive drainage may cause malfunction
of valves and other pneumatic equipment. To prevent this,
install an air dryer, after-cooler or water separator, etc.
3. Use the product within the specified range
of fluid and ambient temperature.
At temperatures of 5
°
C or lower, take measures to prevent
freezing, since moisture in circuits may be frozen and this can
cause damage to seals and lead to malfunction.
Refer to SMC’s “Air Cleaning Equipment” catalog for further
details on compressed air quality.
Mounting
1. Be sure to connect so that the rod axis is
aligned with the load and movement direction.
If they are not aligned, stress could be applied to the rod and
the tube, causing the inner surface of the tube, the bushing, the
rod surface, and the seals to wear and to become damaged.
2. Do not scratch or gouge the sliding parts of
the cylinder tube or piston rod by striking or
grasping them with other objects.
Cylinder bores are manufactured to precise tolerances, so that
even a slight deformation may cause malfunction.
Also, scratches or gouges in the piston rod may lead to
damaged seals and cause air leakage.
3. Do not use until you verify that equipment
can operate properly.
Following mounting, repair or conversions, verify correct
mounting by suitable function and leakage tests after
compressed air and power are connected.
4. Instruction manual
The product should be mounted and operated after thoroughly
reading the manual and understanding its contents.
Keep the instruction manual where it can be referred to as
needed.
