3-20-2. Adjusting the speed controller
The raising and lowering speeds for the work clamp can be adjusted by screwing the knobs on the valve in and out.
Adjust the knob position to set the appropriate speed.
If the upper knob is screwed inward, the work clamp raising speed becomes slower; if it is screwed outward, the
raising speed becomes faster.
If the lower knob is screwed inward, the work clamp lowering speed becomes slower, if it is screwed outward, the
lowering speed becomes faster.
The work clamp can be operated when the power is turned off by pressing the switch.
If the manual button is pushed in and turned to the right, the work clamp can then be held in the raised condition.
Note
The valve knobs should be adjusted so that the left and right sides of the work clamp operate at the same speed.
