Maintenance Instructions

WARNING

source before performing maintenance or making
any adjustment.
Moving Parts Lubrication
Grease all exposed moving parts such as rocker arms
and main bearing approximately every three months.
Make sure to grease main bearing thru grease fitting in-
side clutch handle slot.
Clutch Jaws Lubrication
Clean and lubricate clutch driver jaws with oil after each
use.

Cables

Cables should be thoroughly flushed with water to pre-
vent damaging effects of sediment and drain cleaning
compounds. Periodically lubricate cables and couplings
with RIDGID/Kollmann Cable Rust Inhibitor.
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.
