Electric starter system
For the 2009 model year, MTD introduced an electric
start option for some of its hand held engines. The engines
equipped with the electric start feature can be identified by
the coupler in the sump cover.
There are two types of electric starters available. The
first, is a 110V corded electrical motor assembly. To start
the engine:
1. Plug the starter motor into a power source.
2. Insert the shaft of the motor assembly into the cou-
pler in the sump of the engine.
3. Push the switch to the “ON” position and the starter
will spin the engine at 1,000 RPMs.
4. Once the engine starts, let go of the starter switch
and remove the electric starter from the engine.
The second type of electric starter is an adapter that
fits into an electric drill.
NOTE: The electric drill must spin at 1,000 RPMs of
faster.
The electric starter motor and the adaptor bit are not
serviceable. If they fail, they must be replaced.
The coupler in the sump cover is the same for both
systems. The coupler is part of the sump cover and is ser-
viced/replaced with the sump cover.
Both starter systems have two things in common:
• A 5-sided (pentagon) drive coupler.
• A one-way clutch so the engine does not drive
the electric motor/drill when it starts.
