How To Start The Engine; How To Adjust The Operator Seat - Briggs & Stratton 7800950-01 Operator's Manual

High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable.
For carbureted engines, high altitude adjustment is required
to maintain performance. Operation without this adjustment
will cause decreased performance, increased fuel consump-
tion, and increased emissions. Contact a Briggs & Stratton
Authorized Service Dealer for high altitude adjustment infor-
mation. Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude adjustment is not recom-
mended.
For Electronic Fuel Injection (EFI) engines, no high altitude
adjustment is necessary.
How To Add Fuel
WARNING
Fuel and its vapors are extremely flammable and explo-
sive. Fire or explosion can cause severe burns or death.
When Adding Fuel
• Turn engine off and let engine cool at least 5 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 (A, Figure 4).
2. Fill the fuel tank 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.

How To Adjust The Operator Seat

With the engine stopped:
1. Raise the operator seat.
2. Loosen the two adjusting knobs (A, Figure 5) and move
the seat to the desired position. After adjustment, tighten
the knobs securely.
3. Lower the operator seat.

How To Start The Engine

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 win-
dows, 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.
Electric Start:
1. Sit squarely in the operator seat.
2. Manual Drive Models - Move the transmission shift lever
to the Neutral ('N') position. Refer to "How To Engage The
Transmission".
WARNING
DO NOT start the engine with the transmission shift lever
in a drive position. Follow starting instructions carefully.
3. Make sure the Blade Control (A, Figure 6) is in the OFF
position.
4. Fully depress the Clutch/Brake Pedal (A, Figure 7).
5. Move the engine speed control (A, Figure 8) to the FAST
position (or CHOKE position, if equipped).
NOTE: The CHOKE position is not required when starting a
warm engine.
6. Insert the ignition key (A, Figure 9) into the ignition
switch. Turn the key to the START position until the
engine starts.
NOTE: When the ignition key is turned to START, the engine
will turn over, but will not start unless the Clutch/Brake pedal
is fully depressed and the Blade Control is in the OFF posi-
tion.
