Gasoline 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 gas cap.

•Fill fuel tank outdoors or in well-ventilated area.

•Do not overfill fuel tank. Fill tank to approximately

1-1/2 inches below top of neck to allow for fuel

expansion.

•Keep gasoline 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.

When Starting Engine

•Ensure that spark plug, muffler, fuel cap and air

cleaner are in place and secured.

•Do not crank engine with spark plug removed.

•If engine floods, set choke (if equipped) to

OPEN/RUN position, place throttle in FAST and

crank until engine starts.

When Operating Equipment

•Do not tip engine or equipment at angle which

causes gasoline to spill.

•Do not choke carburetor to stop engine.

When Transporting Equipment

•Transport with fuel tank EMPTY or with fuel shut-off

valve OFF.

When Storing Gasoline Or Equipment With Fuel In

Tank

•Store away from furnaces, stoves, water heaters or

other appliances that have pilot light or other

ignition source because they can ignite gasoline

vapors.

WARNING

Starting engine creates sparking.

Sparking can ignite nearby flammable

gases.

Explosion and fire could result.

•If there is natural or LP gas leakage in area, do not

start engine.

•Do not use pressurized starting fluids because

vapors are flammable.

WARNING

Engines give off carbon monoxide, an

odorless, colorless, poison gas.

Breathing carbon monoxide can cause

nausea, fainting or death.

•Start and run engine outdoors.

•Do not start or run engine in enclosed area, even if

doors or windows are open.

WARNING

Rapid retraction of starter cord (kickback) will

pull hand and arm toward engine faster than

you can let go.

Broken bones, fractures, bruises or sprains

could result.

•When starting engine, pull the starter cord slowly

until resistance is felt, then pull rapidly.

•Remove all external equipment/engine loads before

starting engine.

•Direct-coupled equipment components such as, but

not limited to, blades, impellers, pulleys, sprockets,

etc., must be securely attached.

WARNING

Rotating parts can contact or entangle

hands, feet, hair, clothing, or accessories.

Traumatic amputation or severe laceration

can result.

•Operate equipment with guards in place.

•Keep hands and feet away from rotating parts.

•Tie up long hair and remove jewelry.

•Do not wear loose-fitting clothing, dangling

drawstrings or items that could become caught.

WARNING

Operator Safety

Running engines produce heat. Engine

parts, especially muffler, become

extremely hot.

Severe thermal burns can occur on

contact.

Combustible debris, such as leaves,

grass, brush, etc. can catch fire.

•Allow muffler, engine cylinder and fins to cool before

touching.

•Remove accumulated debris from muffler area and

cylinder area.

•Install and maintain in working order a spark arrester

before using equipment on forest-covered,

grass-covered, brush-covered unimproved land. The

state of California requires this (Section 4442 of the

California Public Resources Code). Other states

may have similar laws. Federal laws apply on

federal land.

WARNING

Before performing adjustments or repairs:

•Disconnect the spark plug wire and keep it away

from the spark plug.

•Disconnect battery at negative terminal (only

engines with electric start.)

•Use only correct tools.

•Do not tamper with governor spring, links or

other parts to increase engine speed.

•Do not strike the flywheel with a hammer or hard

object because the flywheel may later shatter

during operation.

When testing for spark:

•Use approved spark plug tester.

•Do not check for spark with spark plug removed.

Unintentional sparking can result in fire

or electric shock.

Unintentional start-up can result in

entanglement, traumatic amputation, or

laceration.

Oil Recommendations

•Do not use special additives.

•Choose a viscosity from the following chart.

SAE 30 40F and higher (5C and higher)

is good for all purpose use above 40°F, use below 40°F

will cause hard starting.

10W-30 0 to 100F (−18 to 38C)

is better for varying temperature conditions. This grade of

oil improves cold weather starting, but may increase oil

consumption at 80°F (27°C) or higher.

*Check oil level frequently at higher temperatures.

Synthetic 5W-30 −20 to 120F (−30 to 40C)

provides the best protection at all temperatures as well as

improved starting with less oil consumption.

5W-30 40F and below (5C and below)

is recommended for winter use, and works best in cold

conditions.

Check/Add Oil

Before adding or checking the oil

•Place engine level.

•Clean the oil fill area of any debris.

1. Remove the dipstick (B) and wipe with a clean cloth

(Figure 1).

2. Insert and tighten the dipstick.

3. Remove the dipstick and check the oil level. Make sure

the oil is at the FULL mark (C) on the dipstick.

4. To add oil, pour the oil slowly into the engine oil fill (D).

DO NOT OVERFILL. After adding oil, wait one minute

and then recheck the oil level.

5. Fill to the FULL mark (C) on the dipstick.

6. Replace and tighten the dipstick.

Figure 1: Extended Dipstick

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) or up to

15% MTBE (methyl tertiary butyl ether),is acceptable.

Do not use unapproved gasolines, such as E85. Do not

mix oil in gasoline or modify the engine to run on

alternate fuels. This will damage the engine components

and void the engine warranty.

CAUTION

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. To remain

emissions compliant, high altitude adjustment is required.

Operation without this adjustment will cause decreased

performance, increased fuel consumption, and increased

emissions. See an Authorized Briggs & Stratton Dealer for

high altitude adjustment information.

Operation of the engine at altitudes below 2,500 feet (762

meters), with the high altitude kit is not recommended.
