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 the oil level frequently.
C 5W-30
D Synthetic 5W-30

Check and Add Oil
See Figure: 4
Before checking or adding oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the Specifications section for oil capacity.
NOTICE
This engine was shipped from Briggs & Stratton without oil. Equipment manufacturers
or dealers may have added oil to the engine. Before you start the engine for the first
time, make sure to check the oil level and add oil according to the instructions in this
manual. If you start the engine without oil, it will be damaged beyond repair and will
not be covered under warranty.
Check Oil Level
1. Remove the dipstick (A, Figure 4) and wipe with a clean cloth.
2. Install and tighten the dipstick (A, Figure 4).
3. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 4) on the dipstick.
Add Oil
1. If the oil level is low, slowly add oil into the engine oil fill (C, Figure 4). Do not
overfill. After adding oil, wait one minute and then check the oil level.
2. Reinstall and tighten the dipstick (A, Figure 4).

Fuel Recommendations

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). 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
damage the 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 Storage. All fuel is not 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 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.
8
For Electronic Fuel Injection (EFI) engines, no high altitude adjustment is necessary.
Add Fuel
See Figure: 5
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 5) with fuel. To allow for expansion of the fuel, do not
fill above the bottom of the fuel tank neck (B). Some models have a fuel level
indicator (C). Do not fill the tank above the bottom of the fuel level indicator (D).
3. Reinstall the fuel cap.

Charge The Battery Pack

See Figure : 6 7 8 9
WARNING
Improper use of the battery or the charger can result in an electrical shock or
fire.
When Charging Battery Pack
• Charge the Briggs & Stratton battery pack only with the Briggs & Stratton battery
charger.
• Do not use the Briggs & Stratton battery charger to charge any other types of
batteries.
• Keep the battery charger dry. Avoid exposing the battery pack to rain or wet
conditions.
• To reduce risk of damage to the electric plug and cord, pull by the plug rather than
the cord when disconnecting the charger.
• An extension cord should not be used unless absolutely necessary. Use of
improper extension cord could result in a risk of fire and electric shock. If an
extension cord must be used, make sure:
1. That 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. That the extension cord is properly wired and in good electrical condition;
and
3. That the wire size is a minimum of 16 AWG to allow for AC ampere rating of
the charger.
• Do not operate the charger with a damaged plug or cord. The supply cord cannot
be replaced. If the cord is damaged, the charger should be replaced immediately.
• Do not operate the charger if it has received a sharp blow, been dropped, or
otherwise damaged in any way. If the charger is damaged it must be replaced.
The charger is not serviceable.
• Do not disassemble the charger; or attempt to service.
• To reduce risk of electric shock, unplug the charger from outlet before cleaning.
• Do not short circuit; never place any object into the battery contacts.
• The charger is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
• Children should be supervised to make sure that they do not play with the
charger.
When To Charge The Battery Pack
First Time Portable Battery Pack - The Lithium‐Ion portable battery pack was partially
charged before shipment. To maintain charge and to prevent damage while in storage,
the battery pack is programed to enter a "sleep mode". A quick charge of approximately
ten (10) seconds is required to wake up the battery. Leave battery pack in charger
