Chain Tensioning Procedure
Using the Wrapping Machine
All personnel who use (operate and/or maintain) this machine must understand and apply these instructions.
Standard SWA-54 & SWA-60 wrapping machines are suitable for moderate duty, i.e. intermittent cycling with loads up
to 5,000 pounds (2,273kg). This machine should only be used indoors in industrial or commercial settings to wrap
palletized loads of non-hazardous material.
The machine applies stretch-wrap material at a rate of 3-12 revolutions per minute (RPM). The turntable rotates
clockwise. The maximum load width, measured corner-to-corner, must not exceed 76”. Maximum load height is 78”.
Load must always be centered on the turntable
before
it is activated.
The
(see p. 5), accepts rolls of material 10”-20”. The SWA will
generally be capable of achieving stretch rates of 150-200%.
Loading:
•
Verify that no part of the load overhangs the turntable. A damaged skid with a dragging board
or an overhanging load that sags below the turntable can cause the entire load to shift
suddenly if, for instance, it catches on the frame.
•
Do not exceed the capacity of your wrapping machine! Damage to, or premature failure of,
the drive system could result from exceeding the listed capacity. Place loads onto the
turntable slowly and gently using a pallet truck or walk-behind fork lift, using an optional
approach ramp, or with a fork truck.
•
Do not drop loads onto the turntable. Even a two-inch drop onto the turntable creates a shock
load on the load bearings that can cause premature failure.
•
See the installation page in this manual for instructions on how to install a roll of stretch-wrap
material onto the mast carriage.
Gently set, and center, palletized loads on the turntable. Load weight must be evenly distributed on the pallet. The net
weight applied to the machine must not exceed the capacity. The capacity, in pounds and kilograms, is shown on the
machine data label (see label 287 in
Labeling Diagram
on p. 15). Adding ancillary equipment to the turntable, like a
conveyor, must be taken into account when determining the maximum load that can be placed on the turntable.

Numbers in the diagram to the left
correspond to the following
(procedure) numbers. To adjust the
chain tension:
1. Loosen all 4 bolts which hold the
gear reducer to its mounting
bracket.
2. Loosen the jam nuts.
3. Turn the screws clockwise to
increase belt tension (CCW to
reduce tension).
4. Retighten the jam nuts (2) and
mounting bolts (1).
