ELECTRIC START
This generator model is provided with both electric start and
recoil start capabilities. Avoid prolonged cranking, as it can
damage the engine.
The battery provided is a nominal 12 volt sealed recharge-
able lead-acid battery and can be operated in any position
without leakage. It complies with non-spillable battery
regulations. Its convenient size offers a 30% reduction over
conventional batteries.
NOTE: Brand new generators are shipped with the battery
connections disconnected. The positive and negative ter-
