BRIGGS/VANGUARD CONTROLS & START UP PROCEDURE
STARTING THE ENGINE
Note
: Some engines and equipment have remote controls. See the equipment manual for location and
operation of remote controls.
1. Check the engine oil level. See the How To Check/Add Oil section in the engine owner’s manual.
2. Make sure equipment drive controls, if equipped, are disengaged.
3. Turn the fuel shut-off valve (A), if equipped, to the on position (Figure 4).
4. Move the throttle control (B) to the fast position. Operate the engine in the fast position.
5. Pull out the choke control (C), if equipped, to the choke position.
Note: To start the engine with a dry fuel system (first time starting or after running out of fuel), additional
cranking time in the choke position will be required. This will give the fuel pump time to prime the fuel
system.
6. Push the stop switch (D), if equipped, to the on position.
7. Turn the electric start switch (E) to the on/start position (Figure 4).
8. If the engine fires but will not continue to run, move the choke control (C) to the run position to start the
engine.
NOTICE
: To extend the life of the starter, use short starting cycles (five seconds maximum). Wait one
minute between starting cycles.
Note
: If the engine does not start after repeated attempts, go to
VanguardEngines.com or call 1-800-999-9333 (in USA).
9. As the engine warms up, move the choke control (C) to the run position.
Only operate the stump grinder outdoors and avoid breathing engine exhaust and fumes.
WARNING
: Engine exhaust contains carbon monoxide gas that is toxic. Breathing it can cause
unconsciousness and death. Avoid any areas or actions that expose you to carbon monoxide.
