WARNING
Fuel 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 fuel
cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the fuel, do not fill above the
bottom of the fuel tank neck.
• 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.
• If fuel spills, wait until it evaporates before starting engine.
When Starting Engine
• Make sure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in
place and secured.
• Do not crank engine with spark plug removed.
• If engine floods, set choke (if equipped) to OPEN / RUN position, move throttle (if
equipped) to FAST position and crank until engine starts.
When Operating Equipment

• Do not choke the carburetor to stop engine.
• Never start or run the engine with the air cleaner assembly (if equipped) or the air
filter (if equipped) removed.
When Changing Oil
• If you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel can
leak out and result in a fire or explosion.
When Tipping Unit for Maintenance
• When performing maintenance that requires the unit to be tipped, the fuel tank, if
mounted on the engine, must be empty or fuel can leak out and result in a fire or
explosion.
When Transporting Equipment
• Transport with fuel tank EMPTY or with fuel shut-off valve in the CLOSED
position.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel 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
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. You CANNOT see it, smell it, or
taste it. Even if you do not smell exhaust fumes, you could still be exposed
to carbon monoxide gas. If you start to feel sick, dizzy, or weak while using
this product, get to fresh air RIGHT AWAY. See a doctor. You may have carbon
monoxide poisoning.
• Operate this product ONLY outside far away from windows, doors and vents to
reduce the risk of carbon monoxide gas from accumulating and potentially being
drawn towards occupied spaces.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide
alarms with battery back-up according to the manufacturer's instructions. Smoke
alarms cannot detect carbon monoxide gas.
• DO NOT run this product inside homes, garages, basements, crawlspaces,
sheds, or other partially-enclosed spaces even if using fans or opening doors and
windows for ventilation. Carbon monoxide can quickly build up in these spaces
and can linger for hours, even after this product has shut off.
• ALWAYS place this product downwind and point the engine exhaust away from
occupied spaces.
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 and then
pull rapidly to avoid kickback.
• 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
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.
• It is a violation of California Public Resource Code, Section 4442, to use or
operate the engine on any forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in Section
4442, maintained in effective working order. Other states or federal jurisdictions
may have similar laws. Contact the original equipment manufacturer, retailer, or
dealer to obtain a spark arrester designed for the exhaust system installed on this

Service Cooling System
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.
NOTICE Do not use water to clean the engine. Water could contaminate the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can restrict air flow and cause the engine to
overheat, resulting in poor performance and reduced engine life.
1. Use a brush or dry cloth to remove debris from the air intake grille.
2. Keep linkage, springs and controls clean.
3. Keep the area around and behind the muffler, if equipped, free of any combustible
debris.
4. Make sure the oil cooler fins, if equipped, are free of dirt and debris.
After a period of time, debris can accumulate in the cylinder cooling fins and cause the
engine to overheat. This debris cannot be removed without partial disassembly of the
engine. Have a Briggs & Stratton Authorized Service Dealer inspect and clean the air
cooling system as recommended in the Maintenance Schedule.
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel vapors.
Fuel System
See Figure:22
Store the engine level (normal operating position). Fill fuel tank (A, Figure22) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
Fuel can become stale when kept in a storage container for more than 30 days. Each
time you fill the container with fuel, addfuel stabilizerto the fuel as specified by the
manufacturer’s instructions. This keeps fuel fresh and decreases fuel-related problems
or contamination in the fuel system.
It is not necessary to drain fuel from the engine whenfuel stabilizeris added as
instructed. Before storage, turn the engine ON for 2 minutes to move the fuel and
stabilizer through the fuel system.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained
into an approved container. Run the engine until it stops from lack of fuel. The use of a
fuel stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See the Change Engine Oil
section.

Power Ratings:The gross power rating for individual gasoline engine models is
labeled in accordance with SAE (Society of Automotive Engineers) code J1940 Small
Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995.
Torque values are derived at 2600 RPM for those engines with “rpm” called out on the
label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The
gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power
values are taken with exhaust and air cleaner installed whereas gross power values
are collected without these attachments. Actual gross engine power will be higher than
net engine power and is affected by, among other things, ambient operating conditions
and engine-to-engine variability. Given the wide array of products on which engines
are placed, the gasoline engine may not develop the rated gross power when used in a
given piece of power equipment. This difference is due to a variety of factors including,
but not limited to, the variety of engine components (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 engine.

Look For Relevant Emissions Durability Period and Air Index Information On
Your Small Off-Road Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) small off-
road Emissions Standard must display information regarding the Emissions Durability
Period and the Air Index. Briggs & Stratton makes this information available to the
consumer on our emissions labels. The engine emissions label will indicate certification
information.
TheEmissions Durability Perioddescribes the number of hours of actual running
time for which the engine is certified to be emissions compliant, assuming proper
maintenance in accordance with the Operator’s Manual. The following categories are
used:
Moderate:
Engines at or less than 80 cc displacement are certified to be emissions compliant for
50 hours of actual engine running time. Engines greater than 80 cc displacement are
certified to be emissions compliant for 125 hours of actual engine running time.
Intermediate:
Engines at or less than 80 cc displacement are certified to be emissions compliant for
125 hours of actual engine running time. Engines greater than 80 cc displacement are
certified to be emissions compliant for 250 hours of actual engine running time.
Extended:
Engines at or less than 80 cc displacement are certified to be emissions compliant for
300 hours of actual engine running time. Engines greater than 80 cc displacement are
certified to be emissions compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, theEmissions Durability Periodof an engine with anintermediaterating
would equate to 10 to 12 years.
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The Emissions
Compliance Period referred to on the Emissions Compliance label indicates the
number of operating hours for which the engine has been shown to meet Federal

ПРЕДУПРЕЖДЕНИЕ
ОПАСНОСТ ОТ ОТРОВНИ ГАЗОВЕ. Отработените газове от двигателя
съдържат въглероден оксид, отровен газ, който би могъл да Ви убие за
минути. Вие НЕ МОЖЕТЕ да го видите, да го помиришете или вкусите.
Дори ако не помиришете отработените газове, все още можете да бъдете
изложени на въздействието на въглеродния оксид. Ако усетите гадене,
замайване или слабост докато използвате този продукт, ВЕДНАГА излезте
на чист въздух. Отидете на лекар. Възможно е да сте получили отравяне с
въглероден оксид.
• Работете с този продукт САМО на открито, далече от прозорци, врати и
вентилационни отвори, за да намалите риска от натрупване на въглероден
оксид и евентуалното му пренасяне към обитавани пространства.
• Монтирайте сигнални уредби за въглероден оксид, захранвани с батерии
или такива, захранвани чрез контакт, които се включват при появата му,
според инструкциите на производителя. Сигналните уредби за дим не могат
да засичат въглероден оксид.
• НЕ РАБОТЕТЕ с този продукт в домове, гаражи, мазета, непреходни
коридори, хангари или други частично затворени помещения, дори
при използване на вентилатори или при отворени врати и прозорци

Външните температури определят правилния вискозитет на маслото за
двигателя. Използвайте таблицата, за да изберете най-добрия вискозитет за
очаквания диапазон на външна температура. Двигателите на по-голямата част от
оборудването с външно захранване работят добре със синтетично масло 5W-30.
За оборудване, което се използва при високи температури, синтетичното масло
Vanguard
®
15W-50 осигурява най-добра защита.
А SAE 30 - При температури под 40°F (4°C) употребата на SAE 30 ще
доведе до трудно стартиране.
B 10W-30 - При температури над 80°F (27°C) употребата на 10W-30
може да предизвика повишен разход на масло. Проверявайте нивото на
маслото по-често.

2. Монтирайте нивопоказателя (A, Фигура 12).
3. Свалете нивопоказателя и проверете нивото на маслото. Коригирайте нивото
на маслото до горната част на индикатора за напълване (B, Фигура 12) върху
нивопоказателя.
4. Двигателят е с многократно пълнене на маслото (C, G, Фигура 13. Ако нивото
на маслото е ниско, внимателно долейте през отвора за наливане на масло
(C, G). Не препълвайте. След доливане на масло, изчакайте една минута и
след това проверете отново нивото му.
5. Монтирайте отново нивопоказателя (A, Фигура 12).
Система за защита при ниско ниво на
маслото (ако има такава)
Някои двигатели са оборудване с датчик за ниско ниво на маслото. Ако нивото
на маслото е ниско, датчикът или ще включи сигнален индикатор или ще спре
двигателя. Спрете двигателя и следвайте тези етапи, преди да го пуснете отново.
• Уверете се, че двигателят е хоризонтално разположен.
• Проверете нивото на маслото Направете справка в раздела Проверка на
нивото на маслото .
• Ако нивото на маслото е ниско, долейте съответното количество масло.
Пуснете двигателя и се уверете, че предупредителният индикатор (ако има
такъв) не е задействан.
• Ако нивото на маслото е ниско, не пускайте двигателя. Свържете се с
Оторизиран сервизен представител на Briggs & Stratton за отстраняване на
проблема с маслото.
Препоръки за горивото
Горивото трябва да отговаря на следните изисквания:
• Чист, пресен, безоловен бензин.
• Минимум 87октана/87AKI (91RON). За работа при голяма надморска
височина вижте по-долу.
• Бензин, с не повече от 10% съдържание на етанол (бензоспирт), е допустим.
ПРЕДУПРЕЖДЕНИЕ Да не се използват неодобрени марки бензини, като
E15 и E85. Не смесвайте масло с бензина и не модифицирайте двигателя за
работа с алтернативни горива. Употребата на неодобрени горива ще повреди
компонентите на двигателя, което няма да се покрие от гаранцията.
За защита на горивната система от образуване на смола добавете горивен
стабилизатор към горивото. Вижте Съхранение.Не всички горива са еднакви.
Ако започнат да се появяват проблеми със стартирането или производителността,
сменете доставчиците или марката на горивото. Този двигател е сертифициран за
работа с бензин. Системата за контрол на емисиите за карбураторни двигатели е
EM (Модификации на двигателя). Системите за контрол на емисиите за двигатели
с електронно впръскване на горивото са ECM (модул за управление на двигателя),
MPI (многопортово впръскване) и, ако са оборудвани, O2S (кислороден сензор).
Голяма надморска височина
При надморска височина над 5 000 фута (1524 метра) е приемлив бензин с
октаново число минимум 85 /85 AKI (89 RON), където AKI е антидетонационен
коефициент, а RON е окт. число по метода на изследване.
При двигатели с карбуратор се изисква регулиране за голяма надморска височина,
за да се поддържа производителността им. Работа на двигателя, без да е
направено такова регулиране, ще доведе до намаляване на производителността,
повишено потребление на гориво и по-голямо отделяне на емисии. Направете
справка при Оторизиран сервизен представител на Briggs & Stratton за сведения
относно настройката за голяма надморска височина. Не се препоръчва работа на
двигателя при надморска височина под 2 500 фута (762 м) с направено регулиране
за голяма надморска височина.
За двигателите (EFI) с електронно управление на впръскването на гориво не е
необходимо регулиране за голяма надморска височина.
Наливане на гориво
Вижте Фигура: 14
ПРЕДУПРЕЖДЕНИЕ
Горивото и неговите пари са изключително огнеопасни и избухливи.
Пожар или взрив могат да причинят сериозни обгаряния или смърт.
При доливане на гориво
• Изключете двигателя и го оставете да се охлади най-малко 2 минути, преди
да свалите капачката на резервоара за гориво.
• Пълнете резервоара за гориво на открито или в добре проветриво
помещение.
• Не препълвайте резервоара за гориво. За да позволите разширение на
бензина, не пълнете над долната основа на гърловината за наливане на
гориво.
• Дръжте горивото далеч от искри, открити пламъци, сигнални лампи, топлина
и други запалителни източници.
• Проверявайте често горивопроводите, резервоара, капачката и
съединенията за пукнатини и течове Заменяйте ги ако е необходимо.
• Ако горивото се разлее, изчакайте докато то се изпари, преди да стартирате
двигателя.
1. Почистете пространството около капачката на резервоара за гориво от
мръсотия и наслоявания Свалете капачката за горивото.
2. Напълнете резервоара за гориво (A, Фигура 14) с гориво. За да позволите
разширение на горивото, не пълнете над долната основа на гърловината за
наливане на гориво (B).
3. Поставете обратно капачката.

Стартиране на двигателя
ПРЕДУПРЕЖДЕНИЕ
Бързото издърпване на въжето на стартера (обратен удар) придърпва
ръката към двигателя по-бързо отколкото можете да я отдръпнете.
Това може да причини счупване на кости, фрактури, контузии и
навяхвания.
• При стартиране на двигателя, издърпайте бавно пусковото въже докато
усетите съпротивление, а след това дръпнете рязко, за даизбегнете
обратния удар.
ПРЕДУПРЕЖДЕНИЕ
Горивото и неговите пари са изключително огнеопасни и избухливи.
Пожар или взрив могат да причинят сериозни изгаряния или смърт.
При стартиране на двигателя
• Уверете се, че запалителната свещ, шумозаглушителя, капачката на
резервоара за гориво и въздушния филтър (ако има такива) са на мястото
си и са обезопасени.
• Не развъртайте двигателя с извадена запалителна свещ.
• Ако двигателят се задави, поставете смукача (ако има такъв) в позиция
ОТВОРЕНО или РАБОТЕН РЕЖИМ, преместете лоста на газта (ако има
такъв) в позиция БЪРЗО и въртете, докато двигателят стартира.
