3. Clean inside of drum and flange assembly. Certain
cleaning agents and solvents damage plastic parts.
Some of these are: gasoline, carbon tetrachloride,
chlorinated cleaning solvents, ammonia and house-
hold detergents that contain ammonia. Avoiding use
of these and other types of cleaning agents mini-
mizes the probability of damage.

Machine Storage
Motor-driven equipment must be kept in-
doors or well covered in rainy weather. Store the ma-
chine in a locked area that is out of reach of children and
people unfamiliar with drain cleaners. This machine can
cause serious injury in the hands of untrained users.
If machine has been exposed to freezing weather, unit
must be run for ten (10) to twenty (20) minutes without
load to warm up. Failing to do this will result in frozen
bearings. If machine is exposed to weather for a period
of time, moisture will form across motor windings caus-
ing motor to burn out.
