Machine Setup
Chain Clamp Procedure
Loosen the sidewall clamp knobs and remove the chains from the
chain hooks.
Place the Sidewinder on the pipe in the desired vertical or
horizontal position. Center the line bolster on the pipe opposite
the Sidewinder.
Bring the chains around the pipe and bolster and lock in the
chain hooks. Tighten the sidewall clamp knobs until the pipe
conforms to the clamping inserts and line bolster.

Cold Weather and Coiled Pipe Clamping Procedure
Coiled polyethylene pipe becomes very stiff and hard to handle
when cold. In these conditions, sidewall fusion with the sidewinder
becomes more difficult and requires extra procedures in setting up
the machine.
More clamping force than usual will be needed to straighten
the pipe, caution must be taken not to exceed maximum gauge
pressure.
NOTICE: Exceeding the maximum gauge pressure could damage
the gauge.
Back the clamp knobs out to within 1-1/2 or 2 threads left on the
eye bolt and place the machine on the pipe.
It is more difficult to install the machine on the inside curvature of the
pipe than the outside. For this reason, it may be necessary to
rotate the machine slightly to get the clamp knobs in the proper
position. When the clamp knobs are in the proper position, the
machine can be rotated to the desired position and the clamp
knobs tightened.
Install a fitting in the pivot release master. The fitting will exert
pressure and help straighten the pipe.
Use the drive screw to help straighten the pipe and tighten one
side of the pipe clamp. An 8' crescent clamp may be necessary to
achieve full rounding and straightening. Do not exceed maximum
gauge pressure.
Back the drive screw off as the clamp knobs are tightened, so
maximum gauge pressure is not exceeded.
After clamping one side, continue this process on the opposite
side, making sure the gauge pressure is not exceeded.
