2-stage Speed Controller
Shock absorber is not required.
It is possible to shorten traveling (cycle) time as long as
conventional shock absorbing (cushion) property is same.*
*Conventional shock absorbing property means shock absorbing by reducing the cylinder speed by a cylinder mounting type
shock-absorber near the stroke end.
e.g. Actuate 80% of cylinder stroke at the speed of twice as fast as the regular speed of a conventional standard speed
controller,
then actuate the last 20% of the stroke at the regular speed.
Adjustment of shock absorbing property is possible by
the adjustment of 2nd speed (EX2 (CUSHION
2-stage speeds can be controlled by individual needles.
e.g. Reducing the shock to 1/9 (reducing speed to 1/3) while keeping the same cycle time.
Speed shift timing is adjustable.
The speed shifting (brake) timing from EX1 to EX2 can be set at the position where the shock absorber does not work.
Intermediate stop of cylinder is possible.

Detailed Safety Instruction
Warning
Cautions
Adjust a speed of an actuator by referring to Speed adjusting method(Page.4).
Inappropriate procedure may result in rapid action or jumping out of an actuator under incorrect procedure.
1. Since the speed controllers is designed to tolerate some leakage, avoid using on an application requiring complete air-tightness.
2. During braking ( shock absorbing ) process, thrust of a cylinder is reduced by back pressure till the residual air in cylinder is
exhausted completely.
3. Air leak around a cylinder may affect the speed adjustment.
4. Do not block the exhaust ports during the adjustment and operation.

Tips for the adjustment
① Install the product. Connect tube from cylinder port to the OUT side of the product.
②Before carrying out the speed adjustment, fully open TIM and EX1 needles by turning them couterclockwise and completely close
EX2 needle by turning it clockwise.
③Adjust the 2nd (braking) speed with EX2 needle. Actuate the cylinder by gradually opening the EX2 needle so that the piston moves and
reaches to stroke-end. Tighten the lock nut while holding the needle head in order not to change the adjusted speed.
④Adjust the shift (brake) timing with TIM needle. Close TIM needle gradually so that the break (shock absorber function) works near the
stroke end. Do not turn the TIM needle to near full close position or close the needle quickly from full open positon, otherwise speed shifting
effect (brake or shock absorbing function) does not work.
⑤When decelerate the operating speed of the cylinder, adjust EX1 needle and readjust the timing of speed shift (brake) again.
⑥ needle heads of TIM and EX1 in order not to change
the adjusted setting.
・Fix the pressure and the length of tube before adjusting these needles, so that the setting of this product will not be affected.
・As for speed adjusting process①~③, adjust two controlles together at the both sides of the cylinder, then adjust them separately
for process ④~⑥.
・Completely open EX1 needle (accelerate cylinder) and nearly completely close EX2 needle (strengthen a brake), when the timing of

・Adjust all needles over again if encountering a problem.
