Loosen the cross-recessed head screw on the bypass
valve. [Fig. 5]
②
Pull out the knob fully. [Fig. 6]
③
Once the knob is pulled out fully, the bypass valve will
open and the pressure in both the left and right cylinder
chambers for the piston will equalize.
(2) Manual operation procedure
When the manual gear and the manual screw handle are
not installed
When the manual gear (option of double-acting type
cylinder) is installed
①
Operate the clutch in accordance with the instructions on
the nameplate on the gear, and turn the handwheel to
open and close the valve. [Fig. 8]
②
After operation, always return the clutch to the automatic
position setting.
When the manual screw handle (option of single-acting
type cylinder) is installed
①
Loosen the hexagon nut and the hexagon bolt located at
the base of the handle shaft. [Fig. 9]
②
Turn the handwheel in accordance with the direction
indicated on the nameplate located in the middle of the
manual screw handle to open and close the valve. [Fig. 9]
(3) Recovery after completion of manual operation
When the bypass valve is installed
①
Push in the knob all the way, and tighten the cross-
recessed head screw to lock the knob.
②
Reconnect the solenoid valve or the air pipeline.
When the manual gear and the manual screw handle are
not installed
①
Remove spanner, monkey wrench, or special lever.
②
Reconnect the solenoid valve or the air pipeline.
When the manual gear (option of double-acting type
cylinder) is installed
①
After operation, always return the clutch to the automatic
position setting.
②
Reconnect the solenoid valve or the air pipeline.
When the manual screw handle (option of single-acting
type cylinder) is installed
①
After manual operation, always turn the handwheel all the
way in the reverse direction of manual operation until the
handle shaft is at its shortest possible position. [Fig. 9]
②
After returning the handle shaft to its shortest possible
position, tighten the hexagon nut and the hexagon bolt to
fix the handwheel.

(Bypass valve open)
• Do not use a spanner, a monkey wrench, or the
special lever in the following cases as it could result in
a dangerous situation.
(1) For single-acting type cylinders, do not set the
position to open or close manually using a spanner,
a monkey wrench, or the special lever. Otherwise,
the spanner, the monkey wrench, or the special
lever is pushed back by the spring force, which may
cause injury. Use a manual screw handle.
(2) For T750, since the operating force is large and
therefore dangerous, do not perform external
manual operation using a spanner or a monkey
wrench. Use a manual gear.
• Depending on the type of accessories, the special
lever may not be usable.
