The Briggs & Stratton engine you bought with your equipment is made of the finest material in a state-of-the-art manufacturing
facility. Please understand that Briggs & Stratton sells engines to original equipment manufacturers. It also sells to others in the

distribution chain who may sell to the ultimate consumer, an equipment manufacturer, another distributor or a dealer. As aresult,
Briggs & Stratton does not necessarily know the application on which the engine will be placed. For that reason, you should
carefully read and understand the operating instructions of the equipment on which your engine is placed before you operate it.

You should arso understand that there are equipment applications for which Briggs & Stratton does not approve the use of its
engines. Briggs & Stratton engines are not to be used on vehicles with less than 4 wheels. They include motor bikes, aircraft
products and All Terrain Vehicles. Moreover, Briggs & Stratton does not approve of its engines being used in competitive events.

FOR THAT REASON, BRIGGS & STRATTON ENGINES ARE NOT AUTHORIZED FOR ANY OF THESE APPLICATIONS. Fail-
ure to follow this warning could resurt in death, sedous injury (including paralysis) or property damage.

DO NOT choke carburetor to stop engine, especially in an en-

closed vehicle. (Whenever possible, gradually reduce engine

speed before stopping.)
DO NOT tamper with govemor spdngs, links or other parts to

DO NOT operate engine without a muffler. (Inspect periodically
and replace if worn or leaking. If engine is equipped with muf-
fler deflector, inspect periodically and replace if necessary. Be-
placement parts must be same as on original equipment.)

DO NOT operate engine with an accumulation of grass,

leaves or other combustible material in muffler area.

DO NOT use this engine on any forest covered, brush cov-

ered, or grass covered unimproved land unless a spark ar-

rester is installed on muffler. The spark arrester must be main-

tained in working order by the owner and/or operator. In the

State of California the above is required by law (Section 4442
of the California Public Resources Code). Other states may
have similar laws. Federal laws apply on federal lands.

Oil & Fuel Recommendations

Oil

This engine is shipped from Briggs & Stratton without oil.

Before startino enoine, check oil level as shown below.

Change and add oil according to chart below. Do not over-fill.

Use a high quality detergent oil classified "For Service SF,
SG, SH," such as Briggs & Stratton "warranty certified" SAE
30 oil, Part No. 100005. Use no special additives with recom-

mended oils. Do not mix oil with gasoline.

STARTINGTEMPERATURERANGEANTICIPATEDBEFORENEXTOILCHANGE

Air cooled engines runhotter than automotive engines.The use of
multi-viscosity oil such as (10W-30, etc.) in ambient temperatures

above 40° F (4° C) will result in higher than normal oil consumption.
If multi-viscosity oll is used, check the oil level more frequently to

prevent any possible engine damage due to lack of lubrication.

** Use of SAE 30 oil below 40° F (4° C) will result in hard starting

and possible engine damage due to inadequate lubrication.

Check oil level before starting engine.
Add oil as shown below.

Fuel

Use clean, fresh, regular unleaded gasoline with a minimum
of77 octane. Do notmix oilwithgasoline Fresh fuel prevents
gum from forming in fuel system or on essential carburetor
parts. Purchase fuel in quantity that can be used within 30

days. In countries other than the U.S.A., leaded gasoline may

be used ifcommercially available and unleaded is unavailable.
We recommend the use of Briggs & Stratton Gasoline Additive.

(See your Authorized Briggs & Stratton Service Dealer for
Part No. 5041 or the single-use pouch.) See storage instruc-

tions, on page 9.
Note: Some fuels, called oxygenated or reformulated

gasolines, are gasolines blended with alcohots or ethers.

Excessive amounts of these blends can damage the fuel

system or cause performance problems. Do not use gasoline
which contains Methanol. If any undesirable operating

symptoms occur, use gasoline with a lower percentage of
alcohol or ether.

Do not over-fill fuel tank.

Allow space for fuel expansion.

Oil capacity of Model Series 190000 is about 1-1/8 quarts

(36 ounces or 1.1 liters).

Oil capacity of Model Series 280000 is about 1-1/2 quarts

(48 ounces or 1.4 liters).

After filling with or changing oil, start and run engine at idle for

30 seconds. Shut engine off. Wait 30 seconds and check oil
level. Add oil, ifrequired,to bdng level to Full mark on dipstick.

Place engine level. Remove dipstick. "nghton dipstick.

Starting & Stopping

Choke operation/engine warm-up
This engine is a lowemissionsengine whichoperates differently

from previously built engines. It is designed for maximum

performance and life if operated with the choke fully open (in
RUN) and throttlefullyopen (in FAST), To open the choke fully
requires an engine warm-up period of several seconds to

several minutes, depending on the temperature.
After starting engine, first open the choke (toward RUN) until

the engine just begins to runsmoothly.Then open the choke in
small steps, allowing the engine to accept small changes in

speed and load, untilthe choke is fullyopen (in RUN).
During engine warm-up, the equipment can be operated.

To obtain best starting results
Store and fuel lawn mower in level position.

Start lawn mower on hard surface or over previously cut grass.

flammable. Severe engine damage or fire may occur.

Do not use a pressurized startingfluid. Starting fluid is

_ Periodically remove grass build-up under mowerdeck. Remove spark plug wire before removing grass.

When tipping lawn mower to remove grass, keep
spark plug side of engine up.

A warm engine requires less choking than a cold engine.

Starting in cold weather

Use the correct oil for the startingtemperature expected.
De-clutch all possible external loads.
Set speed control at part throttle position.

Awarm battery has more startingcapacity than a cold battery.

Do not use gasoline left over from summer. Use fresh winter
grade gasolinewhich has highervolatilityto improve starting.

Before starting engine
