2. Make sure equipment drivecontrols, if equipped, aredisengaged. See theequipment
manual for location and operation of these controls.
3. Move the throttle control (A, Figure 5), if equipped, to the fast
position.
Operate the enginein the fast
position.
4. If the product is equipped with an engine stop lever (C), hold the engine stop lever
against the handle (Figure 6).
5. Rewind Start: Firmly hold the starter cord handle (D). Pull the starter cord handle
slowly until resistanceis felt, then pull rapidly (Figure 5).
Note: If the engine does not start after three attempts, go to
BRIGGSandSTRATTON.COM or call 1-800-233-3723 (in USA).
WARNING: Rapid retraction of the starter cord (kickback) will pull your
