missing, misaligned or binding parts as well as any
other conditions which may affect the safe and normal
operation of the machine. If any of these conditions are
present, do not use the Drain Cleaning Machine until
any problem has been repaired.
5. Lubricate the Drain Cleaning Machine, if necessary,
according to the Maintenance Instructions.
6. Use tools and accessories that are designed for your
drain cleaner and meet the needs of your application.
The correct tools and accessories allow you to do the
job successfully and safely. Accessories suitable for
use with other equipment may be hazardous when
used with this drain cleaner.
7. Clean any oil, grease or dirt from all equipment han-
dles and controls. This reduces the risk of injury due
to a tool or control slipping from your grip.
8. Inspect the cutting edges of your tools. If necessary,
have them sharpened or replaced prior to using the
Drain Cleaning Machine. Dull or damaged cutting
tools can lead to binding and cable breakage.
9. Inspect cables and couplings for wear and damage.
Cables should be replaced when they become
severely worn or corroded. A worn cable can be iden-
tified when the outside coils become flat.
