Record of Satisfactory Condition
Before using the machine for the first time, record its appearance and operation. Photograph the unit from multiple
angles. Take close range photographs of the anchor points, carriage, labels, motor(s), motor speed controller, the foot
pedal, and junction box and handheld controller (-PMO equipped units only). Include written observations about each
part. Raise and lower the shrink wrap carriage. Include notes about how rapidly the carriage moves up and down the
mast as well as how it sounds during operation. Activate the turntable. Record your observations as well as sounds
heard during operation.
Record the maximum turntable rotation speed to provide a reference for evaluating drive belt
slippage during future maintenance checks.
This record establishes satisfactory condition. Compare the results of every inspection to the record to determine if
the unit is in satisfactory condition. DO NOT use the machine unless it is in satisfactory condition. If repairs are
necessary, only install manufacturer-approved replacement parts.
Inspections & Maintenance
Before inspecting the machine, disconnect it from the electrical power supply. Tag the unit “Out of Service”. Inspect
the unit to determine if it is in
satisfactory condition
. Repair or replace all items that are not in satisfactory condition
before returning the unit to service.
Before each use, including first use, examine the unit for:
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.
Monthly Inspections:
Examine the machine for any of the following conditions at least once per month.
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
replaced.
3. Looseness of the drive belt. Slipping of the drive belt will cause it to wear out rapidly. The turntable will rotate
more slowly than it should or not at all. The belt tension is adjusted by the socket-head screws on the side of the gear
reducer mounting bracket. See
4. Wear or impact damage to the edge of the turntable plate.
Sharp edges or burrs can develop at the edge of the turntable plate when forks scrape the top of
the plate or a fork impacts the edge of the plate during loading/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. Clean off dirt and debris, particularly 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 spinning load is instantly stopped due to a fork
truck backing into the load, damage may occur to the drive system components (belt, pulleys, torque limiter,
gear reducer, motor). Such damage is not covered under warranty. The gear reducer uses. Disassembly of
the gear reducer will void the warranty, and at the manufacturer’s discretion may void all warranty of the stretch-
wrap machine.
