Checking & Adjusting Pull,
Return & Swage Pressures...
Pull Pressure (FIG.4)
(refer to Utilisation (page 6) for correct
setting)
1. With the engine running at operating
speed, observe the display on the Digital
Pressure Switch (Swage Pressure). This
will show the unit of measurement set and
will periodically show “bAr” or “PSI”.
Note:
When facing the hydraulic connectors, the
Digital Pressure Switch (Swage Pressure),
is on the right hand side.
2. Connect a remote electrical trigger (or the
plug/cable from a non-Bobtail Installation
Tool), to the Powerig electrical connector
34.
3. Operate the
remote Trigger
momentarily and
note pressure
reading displayed on
the Digital Pressure
Switch.
CAUTION
Complete this test as quickly as possible
to prevent overload of hydraulic
components.
4. Refer to FIG. 4 and adjust the Pull
Pressure to suit the Installation Tool being
used. Refer to Utilisation (Page 6) and/or
the Installation Tool Instruction Manual for
correct Pull Pressure setting. Only make
small adjustments (1/4 turn) at one time. Do
not remove any pre-installed washers or
locknut from the adjusting screw.
5. Check the Pull Pressure again as
described above. Repeat adjustment if
necessary until correct value is obtained.
6. Once the Pull Pressure has been set,
tighten the Lock Nut on the Adjustment
Screw to ensure setting is retained. Check
the pressure one more time to ensure it had
not changed whilst tightening the Lock Nut.
Return Pressure (FIG 4)
(refer to Utilisation (page 6) for correct
setting)
Notes:
a) The diesel engine does not have to be
running during checking or adjustment of
the return pressure but the key must be in
position 1.
b) When facing the hydraulic connectors,
the Digital Pressure Switch (Return
Pressure), is on the left hand side.
c) The Digital Pressure Switches are able to
measure two SEPARATE pressure switch
points; S1 & S2. Only the S1 is used and
for the Return Pressure, the normally
closed (N/C) switch contacts are utilised. If
the left hand indicator light is on, then the
N/C contacts are closed.
d) The reset pressures r1 & r2 should left at
the factory setting of 50 bar (725 psi).
e) The S1 button is used to change to the
different menu items. The S2 button is
used to access the menu items and the S1
button used again to change the settings of
those menu items.
1. Press both the S1 & S2
buttons at the same time
and the display will show
the first menu item.
2. Press the S2 button
and the current unit
setting will be displayed.
