• Fill the tank with fuel. See Fuel Recommendations
. To allow for expansion of the fuel, do not fill above
the bottom of the filler neck (D).
• Reinstall the fuel fill cap.
6. Clean the exterior surfaces of the cutting deck and engine
of any accumulation of spilled fuel, dirt, grass, oil, etc.
Keep the engine air intake screen and cooling fins clear
at all times.
7. Charge the battery. See Charging the Battery .
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF, SG,
SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
A.
SAE 30 - Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
B.
10W-30 - Above 80°F (27°C) the use of 10W-30 may cause
increased oil consumption. Check oil level more frequently.
C.
Synthetic 5W-30
D.
5W-30
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For high
altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. Use of unapproved fuels will cause
damage to engine components, which will not be covered
under warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See the appropriate Operator's
Manual for recommendations. All fuel is not the same.
If starting or performance problems occur, change fuel
providers or change brands. This engine is certified to
operate on gasoline. The emissions control system for this
engine is EM (Engine Modifications).
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 consumption, and increased emissions. Contact
a Briggs & Stratton Authorized Service Dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 feet (762 meters) with the high altitude
adjustment is not recommended.
For Electronic Fuel Injection (EFI) engines, no high altitude
adjustment is necessary.
Starting the Mower
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.
The engine on your mower is equipped with the Briggs &
Stratton Ready Start™ System. This features a temperature-
controlled automatic choke. No additional steps are required
to start a cold engine.
1. Squeeze the blade control (A, Figure 5) against the
handle.
2. Pull the rope start handle (B) to start the engine.
3. To stop the engine (and blade), release the blade control.
4. After the engine starts, allow a brief warm-up until the
engine runs smooth before beginning mower operation.
