Safety Information
WARNING
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 gas cap.
• Fill fuel tank outdoors or in well-ventilated
area.
• Do not overfill fuel tank.
• 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.
WHEN STARTING ENGINE
• Make sure spark plug, muffler, fuel cap and
air cleaner are in place.
• Do not crank engine with spark plug
removed.
• If fuel spills, wait until it evaporates before
starting engine.
• If engine floods, set choke to OPEN/RUN
position, place throttle in FAST and crank
until engine starts.
WHEN OPERATING EQUIPMENT
• Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY.
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
Gaseous fuels, such as liquid
petroleum gas (LPG) and natural
gas (NG), are extremely flammable
and can readily form explosive
air-vapor mixtures at moderate
temperatures.
IF YOU SMELL GAS:
• DO NOT start the engine.
• DO NOT actuate any electrical switches.
• DO NOT use the phone in the vicinity.
• Evacuate the area.
• Contact the gas supplier or fire department.
REMEMBER:
• LPG vapor is heavier than air and tends to
collect in low areas. NG vapor is lighter then
air and tends to collect in high areas. Both may
travel to remote locations.
• Keep all flames, sparks, pilot lights and other
ignition sources away from the area where the
engine is operated or repaired.
• DO NOT smoke when operating or repairing
the engine.
• DO NOT store gasoline or other flammable
vapors or liquids in the vicinity of the engine.
• BEFORE doing any service work to the
engine, shut off the gas supply.
• After initial installation or servicing, check for
gas leaks. DO NOT use an open flame. Apply
very soapy water or leak test solution with a
brush and look for bubbles.
• Keep the equipment and the area surrounding
the engine free of debris.
• Install the fuel system according to applicable
fuel/gas codes.
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 cord slowly until
resistance is felt, then pull rapidly.
• 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
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
Unintentional sparking can result in
fire or electric shock.
Fire or explosion can cause severe
burns or death.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.
Before performing maintenance or repairs:
• Disconnect spark plug wire and keep it away
from spark plug.
• Disconnect battery at negative terminal (only
engines with electric start).
• Use only correct tools.
• Do not strike the flywheel with a hammer or
hard object because the flywheel may later
shatter during operation.
• Do not tamper with governor spring, links or
other parts to increase engine speed.
When testing for spark:
• Use approved spark plug tester.
• Do not check for spark with spark plug
removed.
WARNING
Wear eye protection when doing
repair work.
Frostbite can result from skin/eye
contact with leaking LP liquid.
• Installation, adjustment and repair work
should be done by a qualified technician.
• Flexible supply lines should be checked
regularly to make sure they are in good
condition. Replace damaged or leaking
components.

Before Starting
Oil
Capacity
The engine holds approximately 80 oz (2.3 liters).
Oil Recommendation
• Use a high quality detergent oil classified “For
Service SG, SH, SJ, SL” or higher, such as Briggs
& Stratton 30, Part Number 100005 (20 oz) or
100028 (48 oz).
• Do not use special additives.
• Do not mix gasoline with oil.
• Choose a viscosity according to the table.
Adding Oil
1. First add 67 oz (2 liters).
2. Start and run engine at idle for 30 seconds.
See Starting Instructions.
3. Shut engine off and wait 30 seconds.
4. Then add more oil slowly to bring level to FULL
mark on dipstick. DO NOT OVERFILL.
Checking Oil Level
• Check oil level before starting the engine.
• Keep oil level at FULL. Do not overfill.
• Check level daily, or after every eight (8) hours of
operation.

CAUTION
* Use of SAE 30 oil below 40° F (4° C) will result in
hard starting and possible engine damage due to
inadequate lubrication.
* * The use of non-synthetic multi-viscosity oils
(5W-30, 10W-30, etc.) in temperatures above 40° F
(4° C) will result in higher than normal oil
consumption. When using a multi-viscosity oil,
check oil level more frequently.
Note: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol (shown
at left) with “SJ/CF ENERGY CONSERVING” or
higher, is an acceptable oil at all temperatures.
Use of synthetic oil does not alter required oil
change intervals.

Oil Fill
Dipstick
1. Place engine level and clean around oil filler plug.
2. Remove dipstick and wipe clean with cloth.
3. Push dipstick back in and remove to check oil
level. Oil level should be at FULL line on dipstick.
4. If oil is needed, add slowly.
5. Fill to FULL line on dipstick − re-check.
6. Replace dipstick firmly.
Oil Pressure
If oil pressure drops below 1−4 psi (0.1−0.2 kg/cm@), an oil pressure
switch (if engine is equipped) will either activate a warning device or
stop the engine. Check oil level with dipstick.
If oil level is between ADD and FULL mark on dipstick do not try to
restart engine. Contact an Authorized Briggs & Stratton Service
Dealer. Do not operate engine until oil pressure is corrected.
If oil level is below ADD mark on dipstick, add oil to bring level to
FULL mark. Restart engine and check oil pressure. If pressure is
normal, continue to operate engine.
Oil pressure gauge, if engine is equipped, is supplied by
Note:
manufacturer of equipment.
