DANGER
: CARBON MONOXIDE. Using an engine indoors CAN KILL YOU
IN MINUTES.
Engine exhaust contains carbon monoxide (CO). This is a poison gas you cannot 
see or smell. If you can smell the engine exhaust, you are breathing CO. But even 
if you cannot smell the exhaust, you could be breathing CO. 
• NEVER use an engine inside homes, garages, crawlspaces, or other partly enclosed
areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or 
opening windows and doors does NOT supply enough fresh air. 
• ONLY use an engine outside and far away from windows, doors, and vents. These
openings can pull in engine exhaust.
Even if you use an engine correctly, CO may leak into the home. ALWAYS use a battery-
powered or battery-backup CO alarm in the home. 
If you start to feel sick, dizzy, or weak after the engine has been running, move to fresh air 
RIGHT AWAY. See a doctor. You may have carbon 
monoxide poisoning. 
To start your engine, perform the following steps:
1. Press the Priming Bulb 2-3 times to prime the engine.
 
 
 
 
 
 
2. If the engine is cold, adjust the Mower’s choke control to 
the CHOKE (START/CLOSED) position.
Note: Location, operation, and design of the choke control 
will vary from manufacturer to manufacturer. Adjust the 
control so that it pulls the choke cable to close the choke. 
 
 
3. Hold the mower’s brake handle closed.
