Enerpac SC-3 - Manual (Page 2)

Cylinders can be changed from right swing to left swing or straight
pull by loosening the side plug and then rotating the plunger to the
desired position. The SC-3 comes with a retract spring for single-
acting operation. The cylinder is shipped with a clamp arm.
4.0 INSTALLATION INSTRUCTIONS
Secure swing clamps to the fixture by any of the following
methods:
1. Screw housing into tapped hole: 1"-12 UN
2. Bolt the unit down using the four mounting holes in the
flange: .201" diameter.
3. Use the optional base: BKTH-6
4. Mount in a through hole and secure with a locknut: JN-4
5.0 OPERATION
5.1 Single-acting
Connect pressure line to port in flange: 1/8"-27 NPT
5.2 Double-acting
Connect advance line to port in flange and retract line (hydraulic
or pneumatic) to bottom port. Use a wrench to hold hex of bottom
fitting when attaching retract line. The vent plug and filter must be
removed prior to attaching hydraulic lines to the retract port.
Plunger return springs may be removed when used as double-
acting.
5.3 Bleeding
Apply low pressure (approx. 10-20 psi) hydraulic pressure to the
system. Loosen the plug opposite the advance port slightly to
allow trapped air to escape, until hydraulic fluid appears. Then
tighten the plug to prevent further leakage.
5.4 Stroke Length
The initial stroke is used for rotation and the remainder is the
clamping stroke.
Stroke: Initial Clamping Total
.50" .25" .75"
5.5 Plunger Rotation
Rotation is clockwise, but can be
changed to counter-clockwise or straight
action by removing the plug (located
opposite the advance port) and ball,
turning plunger so corresponding groove
is visible, and re-assembling ball and
plug. Make sure ball is seated in groove.
5.6 Clamp Arms
Clamp arms supplied with cylinders can be used to full operating
pressure of cylinders and will produce maximum clamping force.
Longer or modified clamp arms will require lowering the maximum
operating pressure and will produce less clamping force. To help
prevent possible internal damage to the cylinder while tightening
the clamp arm to the plunger, we recommend that the bearing
plug located on the side of the cylinder be backed out while
tightening the clamp arm.

* Standard clamping arms supplied. Longer arms indicated in
chart can be fabricated by the user.
Note: Maximum recommended flow rate with standard
arm is 25 in
3 /min. When using longer clamp arms, the
flow rate should be reduced, and an NV-150 flow control
valve should be used.
