Retrieving the cable
8. Move the motor switch to the OFF position. Do not
operate the motor in reverse.
9. Unplug the power cord.
10. Loosen the thumbscrew and hand feed all the cable
back into the drum, cleaning in cold water then oiling
the cable as you go. It is recommended that the cable
is continuously flushed through with clean water and
oiled as it is being retrieved from the pipe before
putting it away. This will prolong cable life and prevent
unpleasant odors as well as the damaging effects of
drain cleaning compounds.
11. Once all of the cable is fed back into the drum, tighten
the thumbscrew.
Post-operation maintenance
12. Drain water from drum. Your model is equipped with
a drain hole in the cable drum. Water, sediment and
debris can corrode cable – remove the drum from the
machine (see “To Remove Drum from Frame” below)
and place it face down to allow all the water to drip
out. This should be done after every use.
MACHINE MAINTENANCE
To reduce the risk of electric shock, fire, serious injury
or death, the motor switch should be OFF and machine
unplugged prior to performing any maintenance,
adjusting, or when cleaning this product.
Cables
• The metal cable should be thoroughly cleaned with
water and lubricated to prolong cable life and prevent
unpleasant odors and the damaging effects of sediment
and drain cleaning compounds. Cleaning and lubricating
should occur prior to storing the machine.
• Regularly inspect cables for damage. Replace cables
that are worn or kinked.
Cleaning the drum machine
This machine is equipped with a drain hole in the cable
drum. It is recommended prior to storage that all water
residues should be removed from the drum. Remove the
drum from the machine (see “To Remove Drum from Frame”
below) and place it face down. This will allow all of the
water to drip out. Confirm the drum is dry prior to storing.
Lubrication
Typically, the drain cleaning machine will not require
lubrication. The bearings will need to be greased with a
general lubricant if the drum is removed or changed. The
cable will need to be lubricated after each use.
Storage
Make sure all water and residue is removed from the
drum prior to storage. Drum should be stored properly
mounted on the machine frame. Store machine in a dry,
safe, secured place, out of the reach of children and people
unfamiliar with this machine.
