SAFETY
WARNING
WARNING
Running engines produce heat. Engine
parts, especially turbocharger and
muffler, become extremely hot.
Fuel and its vapors are extremely flam-
mable and explosive.
Fire or explosion can cause severe burns
or death.
Severe thermal burns can occur on
contact.
WHEN ADDING FUEL
Combustible debris, such as leaves,
grass, brush, etc. can catch fire.
• Turn engine OFF and let engine cool at least 2 minutes
before removing fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Allow muffler, turbocharger, engine cylinder and fins to cool
• Do not overfill fuel tank. Fill tank to approximately 1-1/2
before touching.

and other ignition sources.
• Install and maintain in working order a spark arrester before
using equipment on forest-covered, grass-covered, 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.
• Check fuel lines, tank, cap, and fittings frequently for cracks
or leaks. Replace if necessary.
WHEN STARTING ENGINE
• Make sure muffler, fuel cap and air cleaner are in place.
• If fuel spills, wipe it off before starting engine.

WHEN TRANSPORTING EQUIPMENT
Traumatic amputation or severe lacera-
tion can result.
• Transport with fuel tank EMPTY or with fuel shut-off valve
OFF.
• Operate equipment with guards in place.
• Keep hands and feet away from rotating parts.
• Tie up long hair and remove jewelry.
WHEN STORING FUEL 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 equipment with stored fuel or fuel
source.
• Do not wear loose-fitting clothing, dangling drawstrings or
items that could become caught.
WARNING
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.

SAFETY
WARNING
WARNING
Engines give off carbon monoxide, an
odorless, colorless, poison gas.
Unintentional sparking can result in fire
or electric shock.
Breathing carbon monoxide can cause
nausea, fainting or death.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.
• Start and run engine outdoors.
• Do not start or run engine in enclosed area, even if doors
or windows are open.
BEFORE PERFORMING ADJUSTMENTS OR
REPAIRS
• Disconnect battery at negative terminal.
WARNING
Never remove radiator cap or radiator reservoir
cap while the engine is hot or running. Severe
thermal burns or injury can occur by escaping
steam or hot engine coolant.
WARNING
Briggs & Stratton does not approve or authorize the use of
these engines on 3-wheel All Terrain Vehicles (ATVs), motor
bikes, fun/recreational go-karts, aircraft products or vehicles
intended for use in competitive events. Use of these engines in
such applications could result in property damage, serious
injury (including paralysis), or even death.
• Stop engine and allow to cool before removing radiator or
reservoir cap.
• To remove reservoir cap after engine is cool, place a thick
cloth over cap and remove it slowly.
• To remove radiator cap after engine is cool, place a thick
cloth over cap and rotate it slowly counter-clockwise to
the first stop. Pressurized steam may emit from the cap,
stand back to avoid injury. Once all pressure is released,
rotate cap counter-clockwise while pushing down on cap
to remove.
ENGINE INFORMATION
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 rat-
ing 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 variabili-
ty. Given both the wide array of products on which engines are
placed and the variety of environmental issues applicable to oper-
ating the equipment, the gas engine will not develop the rated
gross power when used in a given piece of power equipment (actu-
al “on-site” or net power). This difference is due to a variety of fac-
tors including, but not limited to, accessories (air cleaner, exhaust,
charging, cooling, carburetor, fuel pump, etc.), application limita-
tions, ambient operating conditions (temperature, humidity, alti-
tude), 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.

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.
Note: After filling with or changing oil, start and run engine at
idle for 5 minutes. Shut engine off. Wait 3 minutes and check oil
level. Add oil, if required, to bring level to Full mark on dipstick.
• Do not overfill.
Bring oil

mark
OIL FILL
on dipstick.
[2]. Remove dipstick and wipe
with clean cloth.
[4]. If oil is required, remove dipstick to allow
proper venting and pour oil slowly. Fill to
FULL line on dipstick. Recheck.
[3]. Then replace dipstick, and
remove to check oil level.
[1]. Place equipment level.
Clean around oil fill.
CAUTION: When filling engine or adding oil.
To prevent engine damage upon
start-up, proper venting is necessary
when filling engine with oil or adding oil.
Note
Clearance
In addition to ensuring a level engine,
removing dipstick, and pouring oil
slowly, there must be clearance
between the oil fill device and the oil fill
hole in the valve cover as shown. This
clearance is necessary to permit
venting when filling, which prevents oil
from overrunning into breather.
Note
Clearance
[5]. Replace dipstick firmly.

FUEL
TYPE OF FUEL TO USE
CAUTION: Do not use kerosene or gasoline
instead of diesel fuel. Failure to observe this caution
will damage the engine.
• THIS ENGINE IS CERTIFIED TO OPERATE
ON DIESEL FUEL.
• Use clean, fresh, diesel fuel with a minimum of 40 cetane.
FUEL LEVEL
• Keep fuel tank full.
WARNING
• Fill fuel tank outdoors or in well-ventilated area,
away from sparks, open flames, pilot lights, heat,
and other ignition sources.
• Do not overfill tank.
• Allow space in tank for fuel expansion.
• If fuel spills, wait until it evaporates before starting
