Continue spreading the flange until the
access gap required has been achieved or
until the maximum tool travel has been
reached.
The Secure Grip mechanical
tools are fitted with an internal mechanical
stop which limits the travel. Forcing the tool
to travel further will result in tool failure.
Tool Max. Distance

Once the flange has been separated
and prior to any maintenance work, the
safety blocks must be inserted between
the flanges. These are held in position by
removing two of the flange bolts that are
reinserted with the safety block positioned
in-between the flange faces.

WARNING
Do not allow fingers, hands
or other body parts to come into contact
with the flange or tools during operations.
Never place fingers, hands or other body
parts into the flange gap.
Following any maintenance works and prior
to closing the flange joint, the safety blocks
must be removed.
To reduce the load on each tool rotate the
actuator bolt one full rotation. Repeat this
on both tools in turn until the tools have no
load on them and the joint is closed.
The tools can then be removed from the
flange by reversing the installation
procedure.
