Record of Normal Condition
Before putting the unit into service, make a written record that describes its functions and appearance. Move the
carriage up and down the mast. Explain how much effort is necessary to move the carriage. Describe sounds heard
while the carriage moves. Activate the turntable by pressing the pedal. How much force is required to press the
pedal? How quickly does the turntable achieve the set rotation speed? How noisy is the turntable when it is
operating? Photograph the unit from several vantage points. Add the photographs to the record. Include
photographs of all labels applied to the unit. Indicate where the labels are applied. This record establishes normal
condition. Always compare your observations during later inspections to the record to determine if the unit requires
repair(s).
Inspections & Maintenance
Never perform maintenance on the unit unless electrical power is disconnected. Resolve all issues found
during each inspection before returning the machine to service.
Before each use , inspect the listed components:
1. Wiring : Examine the wires for fraying and damage.
2. Mast, turntable, and frame : Handrails: check each structure for bends, warps and cracks.
3. Power transmission and control equipment (particularly the foot pedal): Inspect each component and
associated guards and cords for damage.
4. Operate the wrapper : Observe and listen to the machine as it operates for unusual noise or movement, or
binding.
5. Labels : All labels should be readable and located as shown in the Labeling diagram on p. 15. If a label(s) is
unreadable or missing, order a replacement.
NOTE: Label appearance and content is subject to change over time, and consequently, replacement
labels might differ from labels shown in the manual supplied with the unit.
At least 1 time per month , inspect:
1.
Electrical wiring
: Closely inspect wiring for regions of significant wear, cuts, frays, and other damage.
2. Fasteners (hardware) : Check fasteners for looseness and damage. Tighten all loose fasteners; replace any
that are damaged: Bolts, nuts, washers.
3. Turntable : Examine the turntable for significant wear and impact damage. Sharp projections might develop
along the edge of the turntable. Sand or grind off all projections, burrs, etc.
4. Turntable drive chain : Remove the turntable and top inspect the drive chain for significant wear and
looseness. To remove the top, use a 1/2” hex key to remove the (4) lugs located near the center of the tabletop.
If the chain is significantly worn, replace it. Operate the turntable. If the chain is slipping over the gear teeth, it
should be tightened. Apply the Chain tensioning procedure on p. 6. Lightly oil the chain. DO NOT apply grease.
The turntable is driven by a clutch drive system. Grease interferes with the clutch drive.
5. Motor speed control : if the speed control enclosure is broken, then the drive should be replaced.
6. Load bearings/wheels : If the turntable is noisy while it rotates or wobbles during rotation, remove the tabletop
(the procedure for removing the tabletop is described in the exploded views on p. 9 and p. 10 ) and lubricate the
wheels. Replace any wheel that is damaged or significantly worn.
7. Turntable main bearing (part no. 20-110-010 in the exploded views on p. 9 and 10 ): The top of the turntable
should be parallel to the supporting frame; it should not wobble. Press down and pull up on the edge of the
turntable. There should be very little to no wobble. If the tabletop does wobble, tighten the 4 flat socket head
cap screws (part no. 24362 on p. 9 and p. 10 ) near its center; then operate the turntable to see if it still wobbles.
If wobbling still occurs, remove the tabletop (the procedure for removing the tabletop is described in the
exploded views on p. 9 and p. 10 ). Check the load wheels (part no. 16-132-154 on p. 9 & 10 ) closely for wear
and damage.
8. Carriag e assembly : if the hand brake is functioning correctly, the carriage maintains position until the brake is
released by squeezing the release lever. Squeeze the brake and move the carriage up and down the mast. It
should move smoothly. Tighten the roller fasteners if the carriage wiggles. Inspect the rollers for wear.
9.
Fiber washer
(see item no. 7 on p. 5 ): Check the condition of the fiber washers. Make sure that both are in
normal condition. The washers are an important part of the wrap tensioning mechanism. If it becomes difficult to
achieve the desired tension after the machine has been in use for a while, it is likely that one or both washers
have become worn and should be replaced.
10.
Anchors:
Check each anchor bolt (4 total) and the concrete around it. The machine should be solidly attached
to the floor. Tighten bolts, if necessary. The concrete around each bolt should not be cracked, chipped, etc.
11. Labels: Confirm that all labels (shown in Labeling diagram on p. 15) are present, undamaged and readable.
12. Overall condition : The machine should be clean, square and rigid, and free of rust and corrosion. Periodically
clean the surfaces to remove dirt and debris. Do not use the machine if the base is excessively rusted or
corroded.
