o Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures before
beginning work.
o Only qualified individuals trained to understand mechanical devices and their associated electrical circuits should
attempt troubleshooting and repair of this equipment.
o Note: Record the maximum turntable rotation speed when the machine is installed. This will allow a reference for
evaluating drive belt slippage during future maintenance checks.
(A) Before each use inspect for the following:
1.) Frayed or damaged wires.
2.) Damage or structural deformation to the stretch-wrap mast, the machine’s frame, or the turntable.
3.) Damage to any of the machine’s control or power transmission components, particularly to the foot switch, its
guard, or its cord.
4.) Unusual noise or binding, or evidence thereof.
5.) Smooth and proper movement of the stretch-wrap mast carriage.
(B) Inspect monthly for:
1.) Worn or damaged electrical wires.
2.) Damage to the motor speed control. If the speed control’s enclosure has been broken, the drive should be re-
placed.
3.) Looseness of the drive belt. See “Note,” above. Slipping of the drive belt will cause it to wear out rapidly, and the
turntable will rotate slower than intended or not at all. The belt tension is adjusted by the socket-head screws on
the side of the gear reducer mounting bracket. See the “Belt Tensioning Procedure” on the following page.
4.) Wear or impact damage to the edge of the turntable plate.
Warning: Sharp edges or burrs can develop at the edge of the turntable plate by a fork truck’s forks scraping the top
of the plate or by a fork impacting the edge of the plate during loading and unloading. To prevent potential injury to
personnel, these must be filed, sanded or ground smooth.
5.) Damaged or worn load bearings. This is indicated by a scraping sound from the turntable during operation and by
grooves developing on the bottom side of the turntable.
6.) Wear of the turntable’s main bearing. Check that the turntable is parallel with the top of the machine’s frame and
that there is no wobble when the edge of the turntable is shaken.
7.) Excessive wear to the mast carriage slides, or to the fiber washer under the stretch-wrap material .
8.) The integrity of the frame anchors, and for cracks in the concrete around them.
9.) Unusual noises or movement during operation.
10.) All the information, safety, and warning labels being in place and in good condition.
11.) The need to clean off dirt and debris, particularly anything that has built up underneath the turntable.
In the event of a sudden and severe shock load to the turntable’s drive system, such as when the load is stopped instan-
taneously while spinning due to a fork truck backing too close to the load, damage could occur to the drive system compo-
nents (belt, pulleys, torque limiter, gear reducer, motor). Such damage is not covered under warranty.
The gear reducer uses .
The disassembly of the gear reducer will void its warranty, and at the manufacturer’s discretion may void all warranty of
the stretch-wrap machine.
