Add Fuel
See Figure: 6
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When adding fuel
• Turn engine off and let engine cool at least 2 minutes before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the fuel, do not fill above the bottom
of the fuel tank neck.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if
necessary.
• If fuel spills, wait until it evaporates before starting engine.
1. Clean the fuel cap area of dirt and debris. Remove the fuel cap.
2. Fill the fuel tank (A, Figure 6) with fuel. To allow for expansion of the fuel, do not fill
above the bottom of the fuel tank neck (B).
3. Reinstall the fuel cap.

Start and Stop Engine

Start Engine
WARNING
Rapid retraction of starter cord (kickback) will pull hand and arm toward engine
faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
• When starting engine, pull the starter cord slowly until resistance is felt and then pull
rapidly to avoid kickback.
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Starting Engine
• Ensure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in place
and secured.
• Do not crank engine with spark plug removed.
• If engine floods, set choke (if equipped) to OPEN / RUN position, move throttle (if
equipped) to FAST position and crank until engine starts.
WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. You CANNOT see it, smell it, or taste
it. Even if you do not smell exhaust fumes, you could still be exposed to carbon
monoxide gas. If you start to feel sick, dizzy, or weak while using this product,
shut it off and get to fresh air RIGHT AWAY. See a doctor. You may have carbon
monoxide poisoning.
• Operate this product ONLY outside far away from windows, doors and vents to reduce
the risk of carbon monoxide gas from accumulating and potentially being drawn
towards occupied spaces.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms
with battery back-up according to the manufacturer's instructions. Smoke alarms
cannot detect carbon monoxide gas.
• DO NOT run this product inside homes, garages, basements, crawlspaces, sheds,
or other partially-enclosed spaces even if using fans or opening doors and windows
for ventilation. Carbon monoxide can quickly build up in these spaces and can linger
for hours, even after this product has shut off.
• ALWAYS place this product downwind and point the engine exhaust away from
occupied spaces.
