Hint: It's often helpful to have a small stream of water running in the
line to wash the cuttings away while the machine is in operation and
after.
10. When the obstruction is cleared, retract the cable by moving the
feed lever into the reverse position. Keep the motor in the for-
ward position.
SPECIAL OPERATION
IF CABLE GETS CAUGHT IN LINE
The motor can be reversed to free the cable if it gets caught in the
line. Use the following procedure:
1. Move the motor switch to the Reverse position.
2. Tighten the chuck against the cable.
3. Pull on the cable while the drum/cage is turning in reverse.
4. When the cable has been freed, move the motor switch to the
FORWARD position.
DO NOT USE REVERSE TO PULL THE CABLE OUT OF
THE DRAIN. RUNNING MACHINE IN REVERSE CAN
CAUSE THE CABLE TO TANGLE IN THE DRUM.
DISCONNECT MACHINE FROM POWER SOURCE
BEFORE CHANGING CARTRIDGES !
TO CHANGE CABLE CARTRIDGES
Note: Cable Cartridges are only available with the Model DRZ-PH
closed metal drum model with Power Cable Feed.
1. Remove the cutter and connecting screw from the cable if one is
attached.
2. Loosen the knob at the base of the front post and swing the front
post and power cable feed forward.
3. Loosen the three screws around the outside of the drum that hold
the front and back of the drum together.
4. Pull the drum front off the machine, revealing the cable cartridge
within.
5. Pull the cable out of the feed and guide tube and slide it into the
cable cartridge by hand.
6. Remove the cable cartridge.
7. Press replacement cartridge firmly into the back of the drum.
Make sure to line up the grooves in the cartridge with the slots in
the drum back.
8. Slide the cable through the drum front, Power Cable Feed, and
guide tube.
9. Position the drum front so that the three screws align with the
slots in the drum back. Press the drum front into the drum back
and tighten the screws firmly, making sure the screws are cen-
tered in the slots and the heads are flush with the drum.
10. Swing the front post and feed back into position and tighten knob.
10. When the cutter is near the drain opening, take your foot off the
pedal to stop drum rotation. Never retract the cutting tool from
drain while cable is rotating. The cable could whip and cause
serious injury.
OPERATION WITH QUICK-GRIP™ CHUCK
1. Plug machine into a properly grounded outlet.
2. Loosen the chuck at the front of the drum/cage and pull the cable
out of the cage, then put it into the drain until it will not go any
farther. Pull another foot of cable out of the cage so that an arc is
formed between the machine and drain. Tighten the chuck on the
front of the drum/cage firmly against the cable.
3. Make sure the Forward/Off/Reverse switch is in the FORWARD
position
4. Then, with both leather-gloved hands on the cable, step on the
foot pedal. Guide the cable into the line with a firm, even pres-
sure.
5. Do not leave too much slack in the cable since this will cause
whipping. If the cable starts to bend or build up too much twist,
release pressure on the foot pedal and rotate the cage in the
opposite direction to relieve the twist on the cable. Push any
excess cable back into the drum/cage and then continue.
6. When the slack cable has been fed into the drain, stop the ma-
chine by taking your foot off the pedal. Loosen the chuck and pull
another foot of cable from the drum/cage. Tighten the chuck and
continue feeding. Repeat the procedure until the drain line has
been cleared.
7. If you are having trouble getting around bends, try putting the
machine in reverse while applying steady pressure.
8. If you still cannot get around the bend, you are probably using a
cable that is too large.. You may need to switch to a smaller ca-
ble (See Cable Application Chart).
9. After the line is opened, return the cable to the drum/cage with
the motor turning Forward. This is important to prevent tangling
the cable in the cage or in the line.
DO NOT ALLOW TOO MUCH SLACK IN THE CA-
BLE BETWEEN MACHINE AND DRAIN OPENING
SINCE THIS CAN CAUSE CABLE WHIPPING.
DO NOT USE REVERSE TO PULL THE CABLE OUT OF
THE DRAIN. RUNNING MACHINE IN REVERSE CAN
CAUSE THE CABLE TO TANGLE IN THE DRUM.
DO NOT RUN MOTOR IN REVERSE FOR MORE THAN A
FEW SECONDS AT A TIME SINCE THIS COULD CAUSE
THE CABLE TO KINK OR TANGLE IN THE DRUM.
