the same. If start or performance problems occur, change fuel providers or brands. This
engine is certified to operate on gasoline. The emissions control system for carbureted
engines is EM (Engine Modifications). The emissions control systems for engines with
electronic fuel injection are ECM (Engine Control Module), MPI (Multi Port Injection), and
if equipped an O2S (Oxygen Sensor).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON)
gasoline is permitted.
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.
Add Fuel
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
When you add fuel
• Stop the engine. Before you remove the fuel cap, wait a minimum of two (2)
minutes to make sure that the engine is cool.
• Fill the fuel tank outdoors or in an area that has good airflow.
• Do not put too much fuel in the tank. 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.
• Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks
or leaks. Replace damaged parts.
• If fuel spills, wait until it dries before you start the engine.
1. Clean the fuel cap area of dirt and debris. Remove the fuel cap.
2. Fill the fuel tank (A, Figure 5) with fuel. Because fuel will expand, do not fill above
the bottom of the fuel tank neck (B).
3. Install the fuel cap.

Charge the Battery Pack

WARNING
Incorrect use of the battery and charger could result in an electrical shock or fire.
When you charge the battery pack
• Only use Briggs & Stratton battery chargers.
• Do not use the Briggs & Stratton battery charger on other types of batteries.
• Keep the battery charger dry. Do not let the battery pack get wet.
• To decrease the risk of damage to the electric plug and cord, pull the plug, not
the cord, when you disconnect the charger.
• If the charger has a damaged plug or cord, do not use it. The supply cord cannot
be replaced. A damaged charger must be replaced immediately.
• If the charger is damaged do not use it. The charger is not serviceable and must
be replaced.
• Do not disassemble or try to repair the charger.
• To prevent electric shock, disconnect the charger from the outlet before you

• All persons or children with decreased abilities (physical, sensory, mental) must
not use the charger unless looked after by an adult.
Extension cord
• Use of an incorrect extension cord could result in an electric shock or fire. If you
use an extension cord, make sure that:
1. The pins on the plug of the extension cord are the same number, size, and shape
as those of the plug on the charger;
2. The extension cord is correctly connected and in good electrical condition; and
3. For the correct AC ampere rating of the charger, make sure that the wire size is a
minimum of 16 AWG.
When to Charge the Battery Pack
First Time Portable Battery Pack – The Lithium‐Ion portable battery pack was not
fully charged before shipment. To keep charge and to prevent damage while in storage,
the battery pack is programed to go into "sleep mode." A quick charge of approximately
ten (10) seconds is necessary to wake-up the battery. Keep the battery pack in the
charger until fully charged. To charge the battery pack, refer to the How to Charge the
Battery Pack section.

As Necessary – To check available charge, push the button on the Battery Fuel Gauge
(E, Figure 6 7). Refer to Battery Fuel Gauge section.
Storage – For storage periods more than 3 months, fully charge the battery pack before
storage.
How to Charge the Battery Pack
NOTE: Keep the battery charger dry. DO NOT get the battery pack wet.
1. Connect the battery charger (F, Figure 8 9) to an electrical outlet.
2. Portable Battery Pack: Put the portable battery pack (G, Figure 8) tightly into
the battery charging bay (F). If the RED charging light does not show, remove the
battery pack and install it again. Make sure that the battery pack is tightly in the
battery charging bay.
• R ED light (A, Figure 6) shows the battery pack charges correctly.
• G REEN light (B) shows the battery pack is fully charged.
• F lashing RED light (C) shows that the battery pack is too hot or too cold and will
not accept a charge. Keep the battery pack connected. When the battery pack
is at the correct operating temperature, it charges automatically. Refer to the
Specifications section for the correct operating temperature.
• F lashing RED / GREEN lights (D) show that the battery pack does not have a
charge and you must replace it.
3. Portable Battery Pack: From "sleep mode", the battery will wake-up in
approximately ten (10) seconds.
4. Portable Battery Pack: A discharged battery pack will fully charge in approximately
one (1) hour. The battery pack will stay fully charged if kept on the charger.
5. Portable Battery Pack: When the GREEN light shows that the battery pack is fully
charged, remove the battery pack from the charger.
6. Integrated Battery Pack: Connect the charger plug (G, Figure 9) to the engine.
7. Integrated Battery Pack: A discharged battery pack will fully charge in
approximately four (4) hours.
8. Integrated Battery Pack: When the GREEN light shows that the battery pack is
fully charged, remove the battery pack from the charger.
9. To check available charge, push the button on the Battery Fuel Gauge (E,
Figure 6 7).The display lights (H) show the percentage of available charge in the
battery. pack.
10. When the battery pack is not in operation, disconnect the battery charger from the
electrical outlet.
