Maintenance Instructions

WARNING
FOR/OFF/REV switch should be OFF and machine
unplugged before performing any maintenance.
Always wear safety glasses and RIDGID drain clean -
ing gloves and other appropriate protective equip-
ment when performing any maintenance.
Cleaning
The machine should be cleaned as needed with hot,
soapy water and/or disinfectants. Do not allow water to
enter motor or other electrical components. Make sure
unit is completely dry before plugging in and using.
Cables
Cables should be thoroughly flushed with water after
every use to prevent damaging effects of sediment and
drain cleaning compounds. Flush cable with water and
drain debris from drum by tipping machine forward after
every use to remove sediment, etc. which can corrode
cable.
To help prevent corrosion during storage, cables can be
coated with RIDGID Cable Rust Inhibitor. Once the cable
is clean and dry, pull the cable from the drum. While
manually feeding the cable back into the drum, wipe the
Cable Rust Inhibitor on the cable with a cloth.
Do not apply the Cable Rust Inhibitor to a rotating
cable. The cloth and your hand can become entangled in
the cable, and Cable Rust Inhibitor can be slung from ro-
tating cable.
AUTOFEED
After each use, hose out AUTOFEED assembly with
water and lubricate with lightweight machine oil.
Lubrication
Lubricate motor as per instructions on motor.
Lubricate machine with general purpose grease at
grease fitting (located at connection of guide tube and
drum) If drum is changed or removed, once a week if
used every day: once a month if used less.
Front Guide Hose
After use, flush the guide hose with water and drain.
When dry, a small amount of Cable Rust Inhibitor can be
placed in the guide hose to help keep it flexible.
