SAFETY

WARNING

Fuel and its vapors are extremely flammable

and explosive.

Fire or explosion can cause severe burns or

death.

WHEN FUELING

•Turn engine OFF and let engine cool at least 2 minutes before removing cap or refueling engine.

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

•On GASOLINE operated engines, do not overfill fuel tank. Fill tank to approximately 1-1/2 inches below top of neck to allow for fuel expansion.

•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.

WHEN STARTING ENGINE

•Make sure spark plug, muffler, fuel cap and air cleaner are in place, and firmly secured by equipped fasteners.

•Do not crank engine with spark plug, air cleaner cartridge or air cleaner cover removed.

•If fuel spills, wait until it evaporates before starting engine.

•If GASOLINE engine floods, set choke 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

•On GASOLINE engine, transport with fuel tank EMPTY or with fuel shut-off valve OFF.

•On NATURAL / LIQUID PETROLEUM (LP) GAS engines transport with fuel cylinder empty or valve closed, or tank disconnected.

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 are extremely flammable

and readily form explosive air-vapor mix-

tures at ambient 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 trends to collect in low areas. NG vapor is lighter than 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

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.

SAFETY

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

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.

•Remove all external equipment/engine loads before starting engine.

•Direct coupled equipment components such as, but not limited to, blades, impellors, 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

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

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 combustibles from muffler area and cylinder area.

•Install and maintain in working order a spark arrester before using equipment on forest-covered, grass-cov- ered, 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.

Unintentional start-up can result in entanglement, traumatic amputation, or laceration.

BEFORE PERFORMING ADJUSTMENTS OR REPAIRS

•Disconnect spark plug wire and keep it away from spark plug.

•Disconnect battery at negative terminal (only engines with electric start).

WHEN TESTING FOR SPARK

•Use approved spark plug tester.

•Do not check for spark with spark plug removed.

TECHNICAL INFORMATION

Engine Power Rating Information

The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide

array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual “on-site” or net power). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.

OIL

CAUTION: This engine is shipped from Briggs & Stratton without oil. Check oil level before starting engine. If you start the engine without oil, the engine will be damaged beyond repair and will not be covered under warranty.

OIL CAPACITY

Engine without oil filter:

Approximately 44 ounces (1.30 liters)

Engine with oil filter:

Approximately 48 ounces (1.42 liters)

TYPE OF OIL TO USE

•Use a high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher, such as Briggs & Stratton 30W, Part Number 100005 (20 oz) or 100028 (48 oz).

•Do not use special additives.

•Choose a viscosity according to the table opposite.

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.

SAE Viscosity Grades

°F -20	0	20	32	40	60		80	100
°C -30	-20	-10	0		10	20	30	40

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

*CAUTION: Air cooled engines run hotter than automotive engines. 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.

**CAUTION: SAE 30 oil, if used below 40° F (4° C), will result in hard starting and possible engine bore damage due to inadequate lubrication.

CHECKING AND ADDING OIL

•Check oil level before starting the engine.

•Check level daily, or after every eight (8) hours.

•Keep oil level at FULL.

•Do not overfill.

[1]Place engine level and clean around oil fill area.

[2]Remove dipstick and wipe clean with cloth.

[3]Replace and tighten dipstick. Remove and check oil level.

[4]Oil level should be at FULL line on dipstick.

[5]If needed, add oil slowly - recheck. Do not over fill.

[6]Replace and tighten dipstick.
