RECOMMENDATION
• It is recommended that two spreaders be used in tandem.
• Single spreader use is possible but depends on the job at hand.
• Tandem use will give an even spread to the joint.
• The spreaders should be set at 180° apart (see fig.1).
• The spreader needs to be inserted at least as far as the gripping surface to prevent wedge from slipping
out.
• The spreader can be used throughout the whole of the shoes’ gripping surfaces.

IMPORTANT
• Make sure the tool is in fully retracted closed position before
inserting the flange spreader in between the flange faces in
order to fully engage the flange spreader shoes.
• At the beginning of the spread operation check the correct
full engagement of the flange spreader shoes and the grip
between the tool and the flange faces.
• The stepped block shall be inserted into the joint after the tool
has reached full advanced open position.
• After positioning the stepped block, working pressure should
be lowered gradually in order to set the load onto the stepped
block.
• Always ensure that the tool has even and thorough contact
with the work piece.
