Special Procedures; Reverse Operation - RIDGID K-39 Operating Instructions Manual

Cleaning Drain Line
1. Insert cable into drain opening by hand as far as possible before turning
machine on. Leave approximately 6" of cable between drain opening and
nose of machine (Figure 5).
Figure 5 – Keep Distance Between Drain Opening and Nose of Drain
Gun to 6" or Less
2. Be sure machine FORWARD/REVERSE button is in the FORWARD
position.
3. Squeeze trigger and be sure entire cable is spinning before continuing.
NOTE! The K-39 autofeed cannot be used while the hand grip chucking
mechanism is engaged. Be sure the hand grip is pushed forward all the way.
4. Depress the forward autofeed lever to feed cable into drain.
NOTE! Know how long your run of pipe is prior to cleaning. Running too much
cable can damage your equipment and the cable.
5. Feed cable into drain until obstruction is encountered or cable begins to
bind up.
6. K-39: Release the forward autofeed lever and back the cable up using
the reverse autofeed lever. Then use the forward lever to again feed the
cable to remove the obstruction a piece at a time. Continue this back and
forth until you have broken through the obstruction.
K-40: reverse the machine direction to retrieve the cable. Then reverse
again to forward the cable. Repeat till you have broken through the
obstruction.
WARNING: Do not allow tension to build up in the cable. This will happen if
the cutting tool hits a snag and stops turning but the motor and cable continue
to rotate. Torque builds until the cable suddenly twists, potentially wrapping
around your hand or arm. This can happen quickly and without warning, so
proceed slowly and carefully as you feed the cable into the drain. If tool gets
hung up in an obstruction, refer to Reverse Operating Instructions in the
"Special Procedures" section.
7. Once drain is open and fl owing, continue feeding additional cable with
autofeed to clean rest of drain.
8. To retrieve cable, simply depress the reverse autofeed lever (K-39) or pull
the cable back by hand (K-40).
NOTE! K-39: There is no need to reverse the motor direction to retrieve the
cable. Simply depress the reverse autofeed lever.
9. Completely release trigger just prior to cable or tool emerging from drain
opening. Retrieve by hand as cable or tool may contain debris and splash
work area.

Special Procedures

Reverse Operation

If cable/blade gets hung up in obstruction, release trigger switch and let motor
come to a complete stop before reversing.
Place FORWARD/REVERSE button in REVERSE position. Press trigger
switch only until cable/blade is free of obstruction. Release trigger switch
immediately.
CAUTION: Only run machine in REVERSE if relieving blade from a
blockage.
NOTE! When motor direction is in reverse; autofeed directional levers will be
reversed, (FORWARD will become REVERSE and vise versa).
As soon as cable/blade is free and motor has stopped, return FORWARD/
REVERSE button to FORWARD position.
Loading Cable Into Cable Canister
WARNING: Make sure machine is unplugged from power source before
loading cable.
Your K-39, K-39B and K-40 is supplied with an inner drum that fi ts snugly
inside the cable canister that allows easy change-out of cable. K-39 Models
that include extra cable as standard equipment come with an inner drum for
each cable. To utilize the inner drum feature:
1. Pull hand grip forward to the disengaged position.
2. Loosen the four (4) screws that hold the canister front half to the back
half. Loosen each screw 3 (three) full turns (Figure 6).
3. Separate the canister front half from the back half by twisting apart.
4. Lift the inner drum, with cable, out of its cradled fi t.
5. Fit the new inner drum into the canister's back half and draw about a foot
of cable out of the inner drum (Figure 7).

Three (3) Full Turns
