WARNINGS:
To avoid severe personal injury:
Wear
approved eye and ear protection.
Be sure
of adequate clearance for Operator’s hands
before proceeding with fastener installation.
Do not pull on a pin without placing fastener/
collar in a workpiece. This condition can
cause pin to eject with great velocity and
force if the pintail breaks off or teeth/grooves
strip. This may cause severe personal injury.
To avoid pinch point, never place hand
between nose assembly and work piece.
Only use compatible equipment with this
tool.
