How to add grease to the gears
Every 100 hours of use it is recommended that you add wheel bearing grease to the
gears. To get access to the gears, you must remove Crank Case Cover (40) by removing
the six machine screws (37). Next rub wheel bearing grease on all the gears in the
chamber. Replace the Crank Case Cover (40) using the same machine screws (37) that
held it on. See the assembly diagram on page 17 to identify the parts.
Problem
Motor doesn't rotate

NOTE: Other than changing or cleaning the carbon brushes, all other internal repairs
