Installing Penetrating Head; Operating Instructions - RIDGID FlexShaft K9-12 Manual

at the end of the cable, the cable end is flush
with the brush collar. Brush securing rings
are available to improve brush retention if set
screws loosen in use.
As with chain knockers, minimize the amount
of exposed cable (cable not covered by
sheath). The more exposed cable there is, the
more likely the cable will flip over in use and
be damaged. Limit exposed cable to no more
than ¼" (6 mm), set with a bushing made from
sheath ("Knocker Bushing").

Installing Penetrating Head

Penetrating heads are available to help create
a hole in a blockage to get the drain flowing
and allow the chain knocker into an area.
See Figure 13 for installation information.

Operating Instructions

WARNING
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 use with a corded drill. Operating with a
corded drill increases the risk of electrical shock.
Do not allow the chain knocker/end of cable
to stop turning while drill switch is depressed.
This can overstress the cable and may cause
twisting, kinking or breaking of the cable assembly
and may result in serious personal injury.
Practice good hygiene. Do not eat or smoke
while handling or operating the tool. After han-

dling or operating drain cleaning equipment,
use hot, soapy water to wash hands and other
body parts exposed to drain contents. This
will help reduce the risk of health hazards due to
exposure to toxic or infectious material.
Keep 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 3' (1 m) of the drain inlet or properly sup-
port exposed cable assembly when the dis-
tance exceeds 3' (1 m). Greater distances can
cause control problems leading to twisting, kinking
or breaking of the cable. Twisting, kinking or break-
ing cable may cause striking or crushing injuries.
One person must control both the cable as-
sembly and cordless drill. Do not lock drill switch
in the ON position during operation. If the cable
stops rotating, the operator must be able to re-
lease the drill switch to prevent twisting, kinking
and breaking of the cable and reduce the risk
of injury.
Follow operating instructions to reduce the
risk of injury from twisted or broken cable,
cable ends whipping around, machine tipping,
chemical burns, infections and other causes.
1. Make sure that machine and work area is
properly set-up and that the work area is
free of bystanders and other distractions.
2. Pull cable assembly from the machine and
feed into drain. At least 1' (0.3 m) of cable
must be in drain so that the chain knocker
will not come out of the drain and whip
around when the machine is started.
Directly route the cable assembly from the
machine cable outlet to the drain opening,
minimizing exposed cable and changes
in direction. Do not tightly bend the cable
assembly – this can increase the risk of
twisting or breaking.
If using a camera to view the drain clean-
ing process, the camera can be fed in
at the same time. Typically the cable as-
sembly and the camera push rod can be
gripped and advanced/retrieved at the
same time. Keep the camera at least 1.5'
(0.5 m) behind the chain knocker.
Do not allow the spinning chain

knocker to hit the camera head/push rod.
It can damage it.
3. Assume a proper operating position to
help maintain control of the cable assem-
bly and drill (see Figure 14):
