Oil & Fuel Recommendations
Oil
Fuel
This engine is shipped from Briggs & Stratton without oil.
Before starting engine, check oil level as shown below.
Use clean, fresh, regular unleaded gasoline with a minimum
of 85 octane. Do not mix oil with gasoline. 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 if commercially 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 alcohols 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.
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.

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
*
Air cooled engines run hotter 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 oil 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.
Do not over-fill fuel tank.
Allow space for fuel expansion.
Check oil level before starting engine.
Add oil as shown below.

This engine is a low emissions engine which operates differently
from previously built engines. It is designed for maximum
performance and life if operated with the choke fully open (in
RUN)andthrottlefullyopen(inFAST). Toopenthechokefully
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 run smoothly. Then open the choke in
small steps, allowing the engine to accept small changes in
speed and load, until the choke is fully open (in RUN).

puted warranty repairs should be completed in a reasonable amount
of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and re-
sponsibilities, you should contact a B&S Service Representative at
1-414-259-5262.
The emission warranty is a defects warranty. Defects are judged on
normal engine performance. The warranty is not related to an in-use
emission test.
As the ULGE engine owner, you should however be aware that B&S
may deny you warranty coverage if your ULGE engine or a part has
failed due to abuse, neglect, improper maintenance or unapproved
modifications.

About your engine warranty: (see back cover for statement of LIMITED WARRANTY).
Briggs & Stratton welcomes warranty repair and apologizes
to you for being inconvenienced. Any Authorized Service
Dealer may perform warranty repairs. Most warranty repairs
are handled routinely, but sometimes requests for warranty
service may not be appropriate. For example, warranty would
not apply if engine damage occurred because of misuse, lack
of routine maintenance, shipping, handling, warehousing or
improper installation. Similarly, warranty is void if the serial
number of the engine has been removed or the engine has
been altered or modified.
4. Parts which are scored or broken because an engine was
operated with insufficient or contaminated lubricating oil,
or an incorrect grade of lubricating oil (check oil level daily
or after every 8 hours of operation. Refill when necessary
and change at recommended intervals.) Read “Owner’s
Manual.”
5. Repair or adjustment of associated parts or assemblies
such as clutches, transmissions, remote controls, etc.,
which are not manufactured by Briggs & Stratton.
6. Damage or wear to parts caused by dirt, which entered
the engine because of improper air cleaner maintenance,
re-assembly, or use of a non-original air cleaner element
or cartridge. (At recommended intervals, clean and re-oil
the Oil-Foam element or the foam pre-cleaner, and re-
place the cartridge.) Read “Owner’s Manual.”
7. Parts damaged by overspeeding, or overheating caused
by grass, debris, or dirt, which plugs or clogs the cooling
fins, or flywheel area, or damage caused by operating the
engine in a confined area without sufficient ventilation.
(Clean fins on the cylinder, cylinder head and flywheel at
recommended intervals.) Read “Owner’s Manual.”
8. Engine or equipment parts broken by excessive vibration
caused by a loose engine mounting, loose cutter blades,
unbalanced blades or loose or unbalanced impellers, im-
proper attachment of equipment to engine crankshaft,
overspeeding or other abuse in operation.
If a customer differs with the decision of the Service Dealer, an
investigation will be made to determine whether the warranty
applies. Ask the Service Dealer to submit all supporting facts to
his Distributor or the Factory for review. If the Distributor or the
Factory decides that the claim is justified, the customer will be
fully reimbursed for those items that are defective. To avoid
misunderstanding which might occur between the customer
and the Dealer, listed below are some of the causes of engine
failure that the warranty does not cover.
Improper maintenance:
The life of an engine depends upon the conditions under
whichitoperates, andthecareitreceives. Someapplications,
such as tillers, pumps and rotary mowers, are very often used
in dusty or dirty conditions, which can cause what appears to
be premature wear. Such wear, when caused by dirt, dust,
spark plug cleaning grit, or other abrasive material that has
entered the engine because of improper maintenance, is not
covered by warranty.
9. A bent or broken crankshaft, caused by striking a solid ob-
ject with the cutter blade of a rotary lawn mower, or exces-
sive v-belt tightness.
10. Routine tune-up or adjustment of the engine.
11. Engine or engine component failure, i.e., combustion
chamber, valves, valve seats, valve guides, or burned
starter motor windings, caused by the use of alternate
fuels such as, liquified petroleum, natural gas, altered
gasolines, etc.
This warranty covers engine related defective material
and/or workmanship only, and not replacement or refund
of the equipment to which the engine may be mounted.
Nor does the warranty extend to repairs required be-
cause of:
1. PROBLEMS CAUSED BY PARTS THAT ARE NOT
ORIGINAL BRIGGS & STRATTON PARTS.
2. Equipment controls or installations that prevent starting,
cause unsatisfactory engine performance, or shorten en-
gine life. (Contact equipment manufacturer.)
Warranty is available only through service dealers which
have been authorized by Briggs & Stratton Corporation.
Your nearest Authorized Service Dealer is listed in the
“Yellow Pages ” of your telephone directory under “En-
gines, Gasoline” or “Gasoline Engines,” “Lawn Mow-
ers,” or similar category.
3. Leaking carburetors, clogged fuel pipes, sticking valves,
or other damage, caused by using contaminated or stale
fuel. (Use clean, fresh, lead-free gasoline and Briggs &
Stratton gasoline stabilizer, Part No. 5041.)
