PERIODIC MAINTENANCE INSTRUCTIONS
(A) Before Each Use Check For The Following :
1.) Frayed wires
2.) Structural deformation of carousel or frame
3.) Unusual noise or binding
If you find any of the above, discontinue use of the machine until the
necessary repairs are made by a qualified individual!
(B) Inspect Monthly for:
1.) Torque limiter slippage due to friction pad wear. See 8 and 9.
2.) Carousel bearing and chain wear.
3.) Worn or damaged electrical cords.
4.) Shrink-wrap material under the turntable.
5.) Unusual noise when operating.
6.) Gear reducer oil leaks.
7.) Missing or illegible warning labels.
8.) Blocked ventilation ports on the motor speed controller.
Avoid overloading the turntable!
The drive unit of the SWA is protected from overload and shock-loading by a torque limiter
device that is designed to slip only in the event of an overload condition.
An overload will occur:
• When there is excessive weight on the turntable (-48: 4,000lbs.: -54, -60: 5,000 lbs.)
• If there is too much tension on the stretch-wrap material as it's pulled off the roll
• When the rotating load is stopped suddenly
• If the drive chain, sprocket, or bearings become bound with stretch-wrap material
• If placing a pallet on, or removing a pallet from, the turntable while it is rotating
• If the pallet hangs below the turntable and strikes the machine's frame of ramp
• When the load comes into contact with any immovable object
Infrequent maintenance checks can result in continuous slippage of the torque limiter sprocket,
which will cause the turntable to rotate slower than intended. It will also lead to the premature failure of
the torque limiter's friction disks and bushing, which will not be covered under warranty.
In the event of a sudden a severe shock-load to the stretch-wrap turntable, such as when the
load is stopped instantaneously while spinning due to a fork truck backing too close to the load,
damage could occur to the drive system components (chain, sprocket, torque limiter, gear reducer,
motor).
The gear reducer was filled with oil at the factory to operate within a 15°F to 125°F ambient
temperature range. It is permanently lubricated. There's no requirement for oil changes.
The disassembly of the gear reducer will avoid its warranty, and at the factory's discretion may
void all warranty of the stretch-wrap machine.
BE SURE ALL POWER IS OFF BEFORE ATTEMPTING TO WORK ON THIS EQUIPMENT!
CAUTION: SERVICE WORK SHOULD BE PERFORMED ONLY BY TRAINED & QUALIFIED PERSONNEL.
WAIT SEVERAL MINUTES AFTER REMOVING AC POWER BEFORE OPENING THE MOTOR CONTROLLER!
