NOTICE:
This engine was shipped from Briggs & Stratton without oil. Before you start
the engine, make sure you add oil according to the instructions in this manual. If you
start the engine without oil, it will be damaged beyond repair and will not be covered
under warranty.
For information on starting and stopping the engine, read the operating instructions
supplied by the equipment manufacturer.
Note:
Some engines and equipment have remote controls. See the equipment manual
for location and operation of remote controls.
Maintenance
We recommend that you see any Briggs & Stratton Authorized Dealer for all
maintenance and service of the engine and engine parts.
NOTICE:
All the components used to build this engine must remain in place for proper
operation.
Emissions Control
Maintenance, replacement, or repair of the emissions control devices and systems
may be performed by any off-road engine repair establishment or individual.
However, to obtain “no charge” emissions control service, the work must be performed
by a factory authorized dealer. See the Emissions Warranty.
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
Fire hazard
WARNING
Before performing adjustments or repairs:
Disconnect the spark plug wire and keep it away from the spark plug.
Disconnect battery at negative terminal (only engines with electric start.)
Use only correct tools.
Do not tamper with governor spring, links or other parts to increase engine
speed.
Replacement parts must be of the same design and installed in the same
position as the original parts. Other parts may not perform as well, may damage
the unit, and may result in injury.
Do not strike the flywheel with a hammer or hard object because the flywheel
may later shatter during operation.
When testing for spark:
Use approved spark plug tester.
Do not check for spark with spark plug removed.

Check the gap (
A
, Figure 4) with a wire gauge (
B
). If necessary, reset the gap. Install
and tighten the spark plug to the recommended torque. For gap setting or torque, see the
Specifications
section.
Note:
In some areas, local law requires using a resistor spark plug to suppress ignition
signals. If this engine was originally equipped with a resistor spark plug, use the same
type for replacement.
Inspect Muffler And Spark Arrester -

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.
WARNING
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 engine.
Remove accumulated debris from muffler area and cylinder area. Inspect the muffler (
A
,
Figure 5) for cracks, corrosion, or other damage. Remove the spark arrester (
B
), if
equipped, and inspect for damage or carbon blockage. If damage is found, install
replacement parts before operating.
WARNING:
Replacement parts must be of the same design and installed
in the same position as the original parts. Other parts may not perform as well, may
damage the unit, and may result in injury.

Used oil is a hazardous waste product and must be disposed of properly. Do not discard
with household waste. Check with your local authorities, service center, or dealer for safe
disposal/recycling facilities.
Remove Oil From Engine
1. With engine off but still warm, disconnect the spark plug wire (
A
) and keep it away
from the spark plug (Figure 8).
2. Remove the oil drain plug (
B
, Figure 9). Drain the oil into an approved container.
3. After the oil has drained, install and tighten the oil drain plug.
Change The Oil Filter (if equipped)
Some models are equipped with oil filter. For replacement intervals, see the
Maintenance
chart.
1. Drain the oil from the engine. See
Remove Oil
section.
2. Remove the oil filter (
C
) and dispose of properly. See Figure 10.
3. Before you install the new oil filter, lightly lubricate the oil filter gasket with fresh,
clean oil.
4. Install the oil filter by hand until the gasket contacts the oil filter adapter, then tighten
the oil filter 1/2 to 3/4 turns.
5. Add oil. See
Add Oil
section.
6. Start and run the engine. As the engine warms up, check for oil leaks.
7. Stop the engine and check the oil level. It should be at the top of the full indicator (
F
)
on the dipstick.
Add Oil To Engine
Place engine level.
Clean the oil fill area of any debris.
See the
Specifications
section for oil capacity.
1. Remove the dipstick (
D
) and wipe with a clean cloth (Figure 11).
2. Pour the oil slowly into the engine oil fill (
E
).
Do not overfill.
After adding oil, wait
one minute and then check the oil level.
3. Install and tighten the dipstick.
4. Remove the dipstick and check the oil level. It should be at the top of the full indicator
(
F
) on the dipstick.
5. Install and tighten the dipstick.
Remove Oil From Remote Oil Tank
