Operation:
• Stand clear of the machine while it operates. No part of any person, clothing, fork truck, or
other object must contact the rotating load. Do not activate the turntable (by pressing the
foot control) until all persons, equipment, etc. are outside the zone of danger.
• Do not stand or sit on the turntable or its load at any time and particularly when the turntable
is in use.
• Keep all parts of your body and clothing away from the drive system.
• Always carefully watch the load while the turntable rotates.
Do not use the stretch-wrap machine:
1.
If any damage or unusual noise is observed;
2. If repairs are necessary;
3. Is missing any label;
4. Any label is damaged or not easily readable (e.g. faded); or
5.
If it is malfunctioning.
Notify your supervisor or maintenance personnel if you notice anything out of the ordinary.
The standard stretch-wrap machine includes a constant-pressure (“dead-man”) foot pedal switch. Pressing the
pedal turns on the motor and rotates the turntable. The turntable rotates only while the pedal is pressed and coasts to
a stop once the pedal is released.
Turntable rotation speed is adjustable. A speed control knob on the front of the Delta motor speed controller (p. 7)
adjusts the revolutions per minute of the motor shaft. Turn the speed control knob clockwise to increase speed and
counterclockwise to decrease speed. The display on the front of the Delta controller shows the approximate number
of revolutions per minute for the current setting.
Squeeze the hand brake on the carriage assembly to allow it to move up or down the mast..
Stretch-wrap tension is also adjustable. The tension applied to the roll of wrap determines how much the wrapping
stretches as it covers the load. Turning the wing nut of the stretch wrap holder ( p. 5 ; the “SWH”) clockwise increases
the wrapping tension and degree of stretch. Turning the nut counterclockwise decreases material stretch. Set the
tension according to your preference.
Begin a wrapping operation by lowering the SWH. Pull some material from the roll and tie it to the pallet. Press the
foot pedal to rotate the turntable and load. Make 2-3 full revolutions before adjusting the tension on the wrapping
material to achieve the desired stretch rate. Raise and lower the SWH until the load is covered 100%, with two or
three overlapping layers of wrap. Stop the turntable (release the pedal). To finish the wrapping process, either cut (or
tear) the strip of wrapping and press it against the side of the load.
Note: Best results are achieved by overlapping the sides of the pallet at the bottom and extending slightly above the
load at the top.
