Lubrication

Grease all exposed, moving and rotating parts as re-
quired.

Powerfeed Assembly

Proper cleaning and lubrication of the power feed as-
sembly is advised for long, trouble-free operation. After
each use, hose out power feed assembly with water
and lubricate with lightweight machine oil.

Cables

Drain drum after every use. Flush drum periodically, re-
move sediment that can corrode cable.
Cables should be thoroughly flushed with water to prevent
damaging effects of drain cleaning compounds. Periodi-
cally lubricate cables and couplings with RIDGID Cable
Rust Inhibitor. See Accessories for catalog information.
When not in use, store cables indoors to prevent dete-
rioration by the elements.
Cables should be replaced when they become severely
corroded or worn. A worn cable can be identified when
outside coils of cable become flat.

Machine Storage

WARNING
Motor-driven equipment must be kept indoors or well
covered in rainy weather. Store the machine in a locked
area that is out of reach of children and people unfamiliar
with drain cleaners. This machine can cause serious in-
jury in the hands of untrained users.

Service and Repair

WARNING
The "Maintenance Instructions" will take care of most of
the service needs of this machine.
