Check Oil Level; Fuel Recommendations; Charge Battery Pack - Briggs & Stratton 675EXi Series Operator's Manual

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

Check Oil Level

See Figure: 5
Before adding or checking the oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 5) and wipe with a clean cloth.
2. Install and tighten the dipstick (A, Figure 5).
3. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 5) on the dipstick.
4. If oil level is low, slowly add oil into the engine oil fill (C, Figure 5). Do not overfill.
After adding oil, wait one minute and then recheck the oil level.
5. Reinstall and tighten the dipstick (A, Figure 5).
Low Oil Protection System (if equipped)
Some engines are equipped with a low oil sensor. If the oil is low, the sensor will either
activate a warning light or stop the engine. Stop the engine and follow these steps before
restarting the engine.
• Make sure the engine is level.
• Check the oil level. See the Check Oil Level section.
• If the oil level is low, add the proper amount of oil. Start the engine and make sure
the warning light (if equipped) is not activated.
• If the oil level is not low, do not start the engine. Contact a Briggs & Stratton
Authorized Service Dealer to have the oil problem corrected.

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 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.
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.

Charge Battery Pack

See Figure : 7, 8
WARNING
Improper use of the battery and charger can result in an electrical shock or fire.
When Charging Battery Pack
• Charge Briggs & Stratton battery pack only with Briggs & Stratton battery charger.
• Do not use Briggs & Stratton battery charger to charge any other types of batteries.
• Keep battery pack and battery charger dry. Do not expose battery pack or charger
to rain or wet conditions.
• To reduce risk of damage to electric plug and cord, pull by plug rather than cord
when disconnecting 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 pins on plug of extension cord are the same number, size, and shape as
those of plug on charger;
2. That extension cord is properly wired and in good electrical condition; and
3. That wire size is a minimum of 16 AWG to allow for AC ampere rating of
charger.
• Do not operate charger with damaged plug or cord. The supply cord cannot be
replaced. If the cord is damaged, the charger should be replaced immediately.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way. If charger is damaged it must be replaced. Charger is not
serviceable.
• Do not disassemble charger; or attempt to service.
• To reduce risk of electric shock, unplug 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 ensure that they do not play with the charger.
When To Charge Battery Pack
First Time - The Lithium‐Ion 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 until fully charged. To charge the battery
pack, see the How To Charge Battery Pack section below.
