Strap Tension - Signode PN2-2 Operation, Parts And Safety Manual

STRAP TENSION

Failure to use the proper strap/seal/tool
combination for the load being strapping
can result in an improperly secured load
which can result in severe personal
injury. If you have any questions, contact
your local Signode Representative.
Strap tension is controlled by air pressure.
Adjust the pressure regulator to give the
desired tension level. Once the regulator is
set, tension will be uniform on all straps
provided the operator allows the air motor to
stall. The air pressure gauge must be
accurate. Confirm calibration by comparing
it to a master gauge.
Strap breakage hazard. Increasing the
tension can result in strap breakage. If a
strap breaks during tensioning, reduce
the air pressure by 5 psi (0.35 Bar)
increments until the strap does not
break.

If the above air pressures do not result in
tension levels that satisfy your strapping
needs, then increase the air pressure in
increments of 5 psig (.34 Bar) until desired
tensions are achieved.
Do not exceed 90 psig (6.2 Bar) input air
pressure to the tool.
