SET-UP FOR TOOL OPERATION

STRAP TENSION
The PRHM-34 has been factory adjusted to
draw at least 1400 lbs. (6230N) of tension at
90 psig (6.2 bar). A minimum of 70 psig (4.8
bar) is required to ensure that the tool will
seal properly.
Strap tension is accurately controlled by air
pressure to the tool and the setting of the
adjusting screw. Use proper air line piping
and lubricant as specified in this manual.
Air pressure gauge must be accurate.
Confirm calibration at tool gauge by
comparing it to a master gauge.
Adjust strap tension as follows:
1. Make sure the air pressure is set
between 70 and 90 psig (4.8 - 6.2 bar).
2. Loosen the lock nut and turn the
adjusting screw clockwise to decrease
tension and counterclockwise to
increase tension.
Strap breakage hazard. Increasing the
tension can result in strap breakage and
could cause personal injury.
Never remove the adjusting screw from
the tool with the air connected. The
screw could become a flying projectile.
OPERATION POSITIONS
To work effectively, the PRHM-34 must be
properly oriented to the package. This
installation includes, in some cases, proper
suspension of the tool over the container to
be strapped and the proper placement of a
strapping dispenser to provide a continuous
easy supply of strapping for the application.
A spring loaded detent in the tool hanger
allows the tool to be rotated into several
different operating positions shown below.
To adjust the tool position, apply a steady
amount of force to the end of the hanger
bracket. The spring lock will then release
allowing the bracket to be moved to the next
position.
Three of the PRHM's most popular operating
positions are shown below:
