Servicing the Fuel System

WARNING

Fuel and its vapors are flammable and explosive. Fire or explosion could result in

burns or death.

• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition

sources.

• Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks

or leaks. Replace damaged parts.

• If fuel spills, wait until it dries before you start the engine.

Fuel Filter, if installed

1. Before you replace the fuel filter (A, Figure 17), drain the fuel tank or close the fuel

shut-off valve. If the fuel tank is not drained, fuel leakagecanoccur and cause a fire

or explosion.

2. Squeeze the tabs (B, Figure 17) on the clamps (C) with pliers.Move the clamps

away from the fuel filter (A).

3. Twist and pull the fuel lines (D,Figure 17) off of the fuel filter.

4. Examinethe fuel lines (D, Figure 17) for cracks or leaks. If it is necessary, replace

the fuel lines.

5. Replace the fuel filter (A, Figure 17).

6. Attach the fuel lines (D, Figure 17) with clamps (C).

Servicing the Cooling System

WARNING

During operation, the engine and muffler become hot. If you touch a hot engine,

thermal burns can occur.

Combustible debris, such as leaves, grass, and brush can catch fire.

• Before you touch the engine or muffler, stop the engine and wait two (2)

minutes. Make sure that the engine and muffler are safe to touch.

• Remove debris from the muffler and engine.

This is an air cooled engine. Dirt or debris can stop the air flow and cause the engine to

become too hot and result in unsatisfactory performance and decreased engine life.

1. Use a brush or dry cloth to remove debris from the air intake area (A, Figure 18).

2. Keep linkage, springs, and controls (B, Figures 18, 19) clean.

3. Keep the area around and behind the muffler (C, Figures 18, 19) free of

combustible debris.

4. Make sure that the oil cooler fins (D, Figure 18) are free of dirt and unwanted

material.

5. Loosen the fastener(s) (E, Figures 18, 19) and remove the debris access panels

(F). Remove grass and debris that has collected on the cylinders.

6. Install the debris access panels (F, Figures 18, 19) and attach with fastener(s) (E).

Storage

Fuel System

Refer to Figure: 20.

WARNING

Fuel and its vapors are flammable and explosive. Fire or explosion could result in

burns or death.

Fuel Storage

• Because pilot lights or other ignition sources can cause explosions, keep fuel or

equipment away from furnaces, stoves, water heaters or other appliances that

have pilot lights.

Keep the engine level at the correct operating position. Fill the fuel tank (A, Figure 20)

with fuel. For fuel expansion, do not fill above the fuel tank neck (B).

Fuel can become stale when kept in a storage container for more than 30 days.The

use of an alcohol-free fuel stabilizer and ethanol treatment in the fuel storage container

is recommended. This keeps fuel fresh and decreases fuel-related problems or

contamination in the fuel system.

When you fill the container with fuel, addan alcohol-free fuel stabilizer as specified by

the manufacturer’s instructions.If gasoline in the engine has not been treated with a fuel

stabilizer, it must be drained into an approved container. Operate the engine until it is

out of fuel.

NOTE:DO NOT run the Electronic Fuel Injection engine out of fuel. Fuel pump damage

can occur. Make sure to add the correct amount of fuel stabilizer to the fuel tank, and

run the engine for 30 minutes.

Engine Oil

While the engine is still warm, change the engine oil. Refer to Change the 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.

Recomendaciones sobre el aceite

Capacidad de aceite: Consulte la sección Especificaciones.

Recomendamos el uso de aceites Briggs&Stratton® con garantía certificada para

un mejor rendimiento. Se permiten otros aceites detergentes de alta calidad, si están

clasificados para servicio SF, SG, SH, SJ o superior. No use aditivos especiales.

Use el cuadro para seleccionar la mejor viscosidad para el margen de temperatura

exterior que se espera. Los motores de la mayoría de los equipos eléctricos para

exteriores funcionan bien con aceite sintético 5W-30. Para equipos que operan a altas

temperaturas, el aceite sintético Vanguard® 15W-50 brinda la mejor protección.

A SAE30 - El uso de SAE30 a temperaturas inferiores a 40°F (4°C) provocará

dificultades de arranque.

B 10W-30 - El uso de 10W-30 a temperaturas mayores a 80°F (27°C) puede

provocar un aumento en el consumo de aceite. Verifique el nivel de aceite con

frecuencia.

C 5W-30

D 5W-30 sintético

EVanguard®Sintético 15W-50

Verifique el nivel de aceite

Antes de verificar o agregar aceite

Recomendaciones acerca del combustible

El combustible debe cumplir con estos requisitos:

• Gasolina limpia, fresca y sin plomo.

• Un mínimo de 87octanos/87AKI (91RON). Para uso en grandes alturas,

consulte a continuación.

• Se permite gasolina con hasta un 10% de etanol (gasohol).

AVISO

No utilice gasolina no aprobada, como la E15 y la E85. No mezcle la gasolina con

aceite ni cambie el motor para usarlo con combustibles alternativos. El uso de

combustibles no aprobados podría provocar daños a los componentes del motor, lo que

no será reparado bajo la garantía.

Para proteger el sistema de combustible de la formación de goma y la corrosión, mezcle

el combustible con un estabilizador de combustible sin alcohol y un tratamiento de

etanol. Consulte la sección Almacenamiento. No todos los combustibles son iguales.

Si ocurren problemas de arranque o de rendimiento, cambie el proveedor o la marca

del combustible. Este motor está certificado para funcionar con gasolina. El sistema

de control de emisiones para motores carburados es EM (modificaciones del motor).

Los sistemas de control de emisiones para motores con inyección de combustible

electrónica son ECM (módulo de control del motor), MFI (inyección multipunto), TBI

(inyección al cuerpo de aceleración) y, si lo tiene, un O2S (sensor de oxígeno).

Gran altura

En alturas de más de 5000pies (1524metros), se permite una gasolina con un mínimo

de 85octanos/85AKI (89 RON).

Para motores carburados, se requiere realizar el ajuste de gran altura para mantener

el rendimiento. El funcionamiento sin este ajuste provocará una disminución en

el rendimiento y un aumento en el consumo de combustible y en las emisiones.

Comuníquese con un Distribuidor de Servicio Autorizado por Briggs & Stratton para

obtener información sobre el ajuste de gran altura. No se recomienda operar la

máquina a alturas menores de 2500pies (762metros) con el ajuste de gran altura.
