Cleaning

After each use, clean the machine. A mild detergent or
antibacterial solution can be used if desired. Do not
use solvents, abrasives or other harsh cleaning agents.
Machine – Use a damp, soft cloth to wipe off the ma-
chine. Do not submerge or flush the machine with water.
Do not allow water to enter motor or other electrical
components. Make sure unit is completely dry before
plugging in and using.
Drum and Cable – Flush the drum and cable with water
after every use to prevent damaging effects of sedi-
ment and drain cleaning compounds. Drain debris from
drum by tipping machine forward after every use to re-
move sediment, etc. which can corrode cable. Allow to
dry to reduce cable corrosion.

Lubrication

Lubricate machine with general purpose grease at grease
fitting located at connection of guide tube and drum (see
Figure 16). If drum is changed or removed, once a week if
used every day: once a month if used less. Lubricate
cable coupling plunger pins with light machine oil.
