Verify that there will be adequate clearance, so that
the vise jaw can be fully extended to its maximum
8 inch [203 mm] opening without contacting other
objects. Also, verify that there will be suffi cient room
to rotate the vise on the swivel base.
The vise is intended primarily for horizontal mounting,
However, if desired, the vise can also be mounted
vertically.
4.3 Vise Installation
Install the vise as described in the following steps:
1. Assemble the vise to the swivel base as shown in
Figure 3. Tighten the locking nuts hand tight.
2. Route the hydraulic hose through the 1.5 inch
[38,1 mm] diameter hole in the support surface.
IMPORTANT:
One end of the hose is connected to
the vise at the factory prior to shipment. To prevent air
entry, do not disconnect the hose from the vise.
3. Firmly secure the vise and swivel base to the
support surface as an assembly. Use three 39/64"
bolts (user-supplied).
4. Rotate the vise to the desired position on the
swivel base. To change vise position, loosen each
locking nut about one full turn and rotate the vise
to the desired position. After making adjustments,
retighten the locking nuts to secure the vise.
4.4 Hydraulic Connections
Refer to Figure 4 for hydraulic connection diagrams.
A 10,000 PSI [700 bar] rated thermoplastic hydraulic
hose is supplied with the vise.
The hose end contains an Enerpac CH-604 male
quick-disconnect coupler.
A female quick-disconnect coupler (Enerpac CR-400
or equivalent) must be installed in the pump hydraulic
outlet.
If the pump is not equipped with a gauge, install a
0-10,000 PSI [0-700 bar] hydraulic pressure gauge
between the pump outlet and the hydraulic hose.
IMPORTANT:
Be sure that all couplers are properly
connected. Loose or partially connected couplers will
block the fl ow of oil between the pump and the vise.
5.0 OPERATION
WARNING:
Read and understand the
precautions contained in Section 3.0,
Hydraulic Vise Operating Safety,
before
operating the vise. Failure to observe the precautions
in Section 3.0 may result in serious personal injury or
death.
Note:
On vented pumps, be sure that the vent/fi ll cap
is in the “vent” position to allow reservoir venting. If
a vent screw or plug is used, be sure it is loosened
(open).
Operate the vise as described in the following steps:
1. To retract (close) the vise jaw, close the pump
release valve and operate pump.
2. To lock (hold) the vise jaw in position, stop
operating the pump, but keep the pump release
valve closed.
3. To extend (open) the vise jaw,
slowly
open the
pump release valve.
