SAFETY BLOCKS
Each tool is supplied with a Safety Block. The Safety Block
has been designed with steps that match the spreading
distance of the SWi tools.
The Stepped Block Kit contains a larger Safety Block to
cater for wider spreading distances.
3.6
STEPPED BLOCKS
A pair of Stepped Blocks can be supplied as a kit item.
These can be fixed to the jaws (individually or in pairs)
to increase the effective jaw thickness and therefore the
maximum spreading distance.
Use of the Stepped Blocks also enables the SWi5TE Flange
Spreader to be used in a joint with a larger access gap.
Wedge protrusion can be minimised by the use of Stepped
Blocks, reducing the penetration into the joint. This
enables, for example, spectacle blinds to be changed.
Attach the stepped block to the tool using the M6 counter-
sunk screw. Use the hex-key supplied to tighten the screw
into the threaded hole in the jaw of the tool. Repeat for
second Stepped Block to further increase the effective jaw
thickness if required.
3.3
FLANGE WORK
DANGER:
Do not rely upon hydraulic systems
for supporting the access gap during flange
work. Do not allow fingers, hands or other body
parts into the space created between the
flanges.
3.4
FLANGE CLOSURE
Allow the flanges to return to their closed position by
gradually retracting the tool. Consult the relevant section
of the manual for instructions on how to retract the tool.
Before the tool has fully retracted, insert the Safety
Blocks into the flange joint. Ensure the full breadth of
the selected Safety Block step is fully inserted, before
gradually retracting the tool until the flange load has been
applied to them.
To use the next smallest step, place the tool in the gap
and actuate enough to relieve the load on the Safety
Blocks. In this way the flange joint can be progressively
closed.
As the flange approaches its fully closed position, support
the tool to avoid it dropping out of the joint. Ensure that
care is taken to prevent objects being dropped. Dropped
objects pose a risk of personal injury or equipment
damage.
