Collar distance can be modified to your
preference for the specific pipe/applica-
tion. As collar distance increases, the di-
ameter of the chains decreases, and vice
versa. Improperly set collar distance can
reduce the efficiency of pipe cleaning.
7. Test fit the chain knocker, knocker bushing
and collar spacer on the cable as shown
in Figure 7. Chains should be straight – do
not assemble with chains twisted. To pre-
vent excessive cable end wear, cable end
should be flush with the end of the collar.
Check length of exposed cable. To reduce
the risk of cable flip over and damage,
exposed cable cannot exceed ¼" (6 mm).
If needed, cut a knocker bushing from
sheath to limit exposed cable. Always
use a knocker bushing to reduce wear
on the sheath end.
8. With the chain knocker correctly installed
on the cable as shown in Figure 7, use
the supplied hex wrench to securely
tighten the collar set screws. If the set
screws are not secure, the chain knocker
could slip and damage the cable or be
lost down the drain.

Operation Instructions
Always use safety glasses and gloves in good
condition while handling or using. Use latex or
rubber gloves, face shields, protective clothing,
respirators or other appropriate protective equip-
ment when chemicals, bacteria or other toxic or
infectious substances are suspected to be present
to reduce the risk of infections, burns or other
serious personal injury.
Do not allow the chain knocker/end of cable to
stop turning while cable assembly is turning.
This can overstress the cable and may cause
twisting, kinking or breaking of the cable assembly
and may result in serious personal injury.
Keep a hand on the cable assembly whenever
the FlexShaft Machine is running. This provides
better control of the cable and helps prevent twist-
ing, kinking and breaking of the cable and reduces
the risk of injury.
Position the FlexShaft Machine cable outlet
within 4' (1.2 m) of the drain inlet or properly
support exposed cable assembly when the dis-
tance exceeds 4' (1.2 m). Greater distances can
cause control problems leading to twisting, kinking
