Swage Pressure (FIG 4
(only applicable when using IT type tools.
Refer to Utilisation (page 6) for correct
setting)
Note:
When using IT type Bobtail Installation
Tools, fitted to the Powerig connector 35
with the electrical 8 pin Lemo Plug, the
Digital Pressure Switch (Swage Pressure)
6, controls the hydraulic pressure to the tool
during the pull cycle. This in turn controls
the amount (length) of Bobtail fastener
Collar swage. The higher the pressure, the
more the Collar is swaged.
This Digital Pressure Switch is checked and
adjusted using the same procedure as that
for the Digital Pressure Switch for the
Return Pressure as previously explained.
The indicator will light not be illuminated as
the normally open contacts should be in the
open condition.
Set a Swage Pressure just above the
minimum required for the Nose Assembly
Anvil to just lightly contact the Collar
Flange. A circular witness mark around the
Collar flange will indicate the Anvil contact.
On most large diameter (12 mm (1/2”) and
above), Bobtail Collars have a series of
raised nodules around the flange which will
be crushed by contact with the Anvil.
Do not adjust the Swage Pressure too high
as this increases the risk of Bobtail grooves
being stripped/damaged or the Bobtail being
broken away from the Pin. In either event,
this will prevent a Bobtail Collar Cutter from
being used to remove the installed fastener.
14.
Inspect hoses, electrical cords and
connections frequently for signs of
damage or ageing. If necessary replace.
15. Connect both hoses of the Installation
Tool, (or if being used with a Hose Set,
connect the Hose Set), to the Powerig.
Activate the Tool Trigger to fully cycle the
Tool, or if using an “IT” type Bobtail Tool,
then use a remote trigger attached to the
Powerig connector 34.
Note:
It is not possible to cycle IT type Bobtail
Tool s using it’s own trigger unless the tool
Limit Switch is activated (contacts close).
Therefore a remote Trigger as described
above must be used.
CAUTION
BTT series tools do not have a Dump
Valve to relieve hydraulic pressure from
the front of the Piston.
Therefore, release the trigger
immediately when the tool Piston has
stopped moving.
CAUTION
Some types of Installation Tool (e.g. BTT
and SFBTT series, extend in length
during operation.
16. When using tools other than BTT Bobtail
Tools, continue to press the trigger for
approx. 4 seconds when the Tool Piston has
stopped moving. Release the Trigger and
and allow the Tool Piston to return to the
starting position. Repeat three times.
This will ensure that any air in the hydraulic
system is removed.
Note:
New Hose Sets or individual hoses my not
contain any hydraulic fluid and the air must
be removed. To do this, connect one pair of
couplings at one end of the Hose set, to the
Powerig. Connect the other pair of Hose
set couplings to each other. With the
Powerig running, activate the remote
trigger/tool trigger and then release. Wait
approx. 45 seconds, then stop the Powerig.
Check the Powerig hydraulic oil level before
continuing.
17. Check the Pull Pressure again and re-
closes-adjust if necessary. Tighten the Lock
Nut to
ensure settings to not change.
