Installing/Adjusting Chain Knocker - RIDGID K9-306 FlexShaft Mode D'emploi

• Is in good condition.
• Has a plug similar to that supplied on
the drain cleaner.
• Is rated for outdoor use and contains
a W or W-A in the cord designation
(i.e. SOW), or complies with H05VV-F,
H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size. For extension
cords up to 50' (15,2 m) long use 16
AWG (1,5 mm
sion cords 50'-100' (15,2 m – 30,5 m)
long use 14 AWG (2,5 mm
When using an extension cord, the GFCI
on the drain cleaner does not protect the
extension cord. If the outlet is not GFCI
protected, it is advisable to use a plug
in type GFCI between the outlet and
the extension cord to reduce the risk of
shock if there is a fault in the extension
cord.

the O-OFF position, and with dry hands
unplug the machine.
Installing/Adjusting Chain
Knocker
1. Select proper chain knocker for the con-
ditions.
Chain knockers are sized based on col-
lar inside diameter and are designed for
specific cable sizes. 3/8" chain knockers
are used on 3/8" cable, etc. Do not use
a larger size chain knocker on a smaller
cable (for instance 1/2" on 3/8"). See Fi-
gure 6 and Collar Distance Chart.
Chain knockers without carbide cutting
tips can be used in common pipe types.
These chain knockers work well in grease
and similar blockages.
Chain knockers with carbide cutting tips
are used for removing scale from the
inside of the pipe and can be used for
roots. Carbide cutting tips are used for
aggressive cleaning and could damage
pipe, especially softer materials (such
as plastics and Orangeburg), thin walled
pipe, or if the chain knocker is kept in one
position for an extended time.
Do not use chain knockers for cleaning in
glass, ceramic, porcelain or similar ma-
terial fixtures or pipes. They could be
damaged.

FlexShaft™ Drain Cleaning Machine
There are two key points when installing/
adjusting chain knockers.
Collar Distance: Set the chain knocker
collars the correct distance apart ("Collar
Distance") to allow the chains to spread
an appropriate amount when rotated to
clean the pipe walls. Collar Distance var-
ies based on cable size and pipe diam-
eter, and is generally set using a spacer
made from sheath ("Collar Spacer"). If
additional flexibility is required to navigate
a bend, the collar spacer can be removed
and the collar distance can be set with a
tape measure. Operating without a collar
spacer makes it more likely for the cable
to flip over in use and be damaged. Do
not operate carbide cutters without a
collar spacer to reduce risk of cable
damage.
Exposed Cable: 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. Exposed cable
should be limited to no more than ¼" (6
mm), and is set with a bushing made from
sheath ("Knocker Bushing").
Sheath is supplied with the drain cleaner
and is available as a service part to allow
configuration as needed for your specific
application. Only use RIDGID FlexShaft
Drain Cleaner sheath of the correct size
for the cable. Any time sheath is cut, it
should be cut cleanly and squarely. Do
not damage the cable when cutting the
sheath.
3. Chain knockers are retained to the cable
with set screws that use a supplied 3 mm
hex key. Loosen set screws and remove
chain knocker, spacer and bushing from
cable.
4. With no knocker installed, hold cable end
away from your body or others. Run ma-
chine in REVERSE for 5 seconds to max-
imize exposed cable. Place switch in
O-OFF position and unplug machine.
Hold sheath and pull on cable to remove
slack and expose maximum amount of
cable.
5. Inspect the sheath end for damage or
wear. The sheath end should be square
and clean. If needed, the sheath end can
be trimmed slightly.
6. If needed, cut a section of sheath to use
as the collar spacer to the appropriate
size (See Collar Distance Chart).
