2. CAUTION
2.1 Fluid
1) Use the compressed air,filtrated and
dehumidified. Carefully select a filter
of an adequate filtration rate (5μm or
lower preferred), flow rate and its
mounting location (asclosest to direc-
tional control valve as possible)
2) Be sure to drain out the accumulation
in filter periodically.
3) Note that the intrusion of carbide of
compressor oil (such as carbon or tarry
substance) into the circuit causes
malfunction of solenoid valve and cyl-
inder.Be sure to carry out thorough
inspection and maintenance of com-
pressor.

3. OPERATION
Setting the cylinder speed
Turning the handle ①clockwise re-
duces the speed of cylinder,finally
closing the controller,while turning it
counterclockwise increases the speed
of cylinder.Tobuild ameter out cir-
cuit, close the controller first by turn-
ing its handle ①clockwise, then con-
nect it to the piping so that the casted
JIS symbol on the body ③matches
with the direction of flow as per des-
igned schematic.
While giving pressure to the circuit, turn the handle ①of controller
counterclockwise until the required speed of the cylinder is set. Once the
position of the handle ①is set, make sure to tighten up the lock nut ②.
Note :
The cylinder will no longer gain its speed after the handle ①is turned ap-
prox. 8 to 10 times from the fully closed position as the controller gets out
of the controllable range of speed.

4. INSTALLATION
4.1 Piping
1) For piping beyond the filter, use pipes that are tough against corrosion such
as galvanized pipes, nylon tubes, rubber tubes, etc. (Refer to Selection
Guide Table for Related Equipment.)
2) See to it that the pipe connecting cylinder and solenoid valve has effective
sectional area which is needed for the cylinder to drive at the specified speed.
(Refer to Selection Guide Table for Related Equipment.)
3) Install filterpreferably adjacent to the
upper-stream to the solenoid valve for
eliminating rust, foreign substance in
the drain of the pipe.
4) Be sure observe the effective thread
length of gas pipe and give achamger
of approx. 1/2 pitch from the threaded
end.
5) Flush air into the pipe to blow out for-
eign substances and chips before piping.
6) Refrain from mapplying sealant or sealing tape approx. two pitches of thread
off the tip of pipe to avoid residual substances from falling into piping sys-
tem.

5. MAINTENANCE
5.1 Trouble shootig
Trouble Causes Remedies
1. The controller is installed in
the erroneous direction per
specified on the schematics.
Reaffirmthe direction of flow and
correct it if found the connection is
incorrect.
Turning the handle of control-
ler does not influence to the
speed of cylinder 2. Foreign particle is caught by
packing Blow away the foreign particle by means of air flushing.
