Never start the engine if the battery cables are loose.
•
Turn the key to the off position before disconnecting, removing and / or installing the
battery.
•
Never use a battery charger to start the engine.
•
Never disconnect the battery cables while the engine is running.
•
When connecting the battery cables, first connect the positive (+) cable and then
connect the negative (-) cable to the battery.
•
When charging the battery, turn the ignition switch to the off position and disconnect
the negative (-) battery cable from the battery.
•
Do not spray water directly on the Electronic Control Unit.
Carburetor and Engine Speed
Never make adjustments to the carburetor or engine speed. The carburetor was set at the
factory to operate efficiently under most conditions. Do not tamper with the governor spring,
linkages, or other parts to change the engine speed. If any adjustments are required contact
a Briggs & Stratton Authorized Service Dealer for service.
NOTICE
The equipment manufacturer specifies the maximum speed for the engine
as installed on the equipment. Do not exceed this speed. If you are unsure what the
equipment maximum speed is, or what the engine speed is set to from the factory,
contact a Briggs & Stratton Authorized Service Dealer for assistance. For safe and
proper operation of the equipment, the engine speed should be adjusted only by a
qualified service technician.
Service Spark Plug
See Figure: 7
Check the gap (A, Figure 7) 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.
Service Exhaust 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.
•
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 and cylinder area. Inspect the muffler for cracks,
corrosion, or other damage. Remove the deflector or the spark arrester, 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.
Change Engine Oil
See Figure: 8, 9, 10
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
1.
With engine off but still warm, disconnect the spark plug wire(s) (D, Figure 8) and
keep it away from the spark plug(s) (E).
2.
Remove the dipstick (A, Figure 9).
3.
Remove the oil drain plug (F, Figure 10). Drain the oil into an approved container.
4.
After the oil has drained, install and tighten the oil drain plug (F, Figure 10).
Change Oil Filter, if equipped
Some models are equipped with an oil filter. For replacement intervals, see the
Maintenance Schedule.
1.
Drain the oil from the engine. See Remove Oil section.
2.
Remove the oil filter (G, Figure 10) and dispose of properly.
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. Correct oil level is at the top of the full indicator
(B, Figure 9) on the dipstick.
Add Oil
•
Make sure the engine is level.
•
Clean the oil fill area of any debris.
•
See the Specifications section for oil capacity.
1.
Remove the dipstick (A, Figure 9) and wipe with a clean cloth.
2.
Slowly pour oil into the engine oil fill (C, Figure 9). Do not overfill. After adding oil,
wait one minute and then check the oil level.
3.
Install and tighten the dipstick (A, Figure 9).
4.
Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 9) on the dipstick.
5.
Reinstall and tighten the dipstick (A, Figure 9).
6.
Connect the spark plug wire(s) (D, Figure 8) to the spark plug(s) (E).
Service Air Filter
See Figure: 11
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
•
Never start and run the engine with the air cleaner assembly (if equipped) or the air
filter (if equipped) removed.
NOTICE
Do not use pressurized air or solvents to clean the filter. Pressurized air can
damage the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Various models use either a foam or a paper filter. Some models may also have an optional
pre-cleaner that can be washed and reused. Compare the illustrations in this manual with
the type installed on your engine and service as follows.
1.
Open the fastener(s) (A, Figure 11) and remove the cover (B).
2.
Remove the nut (C, Figure 11) and the retainer (D).
3.
To prevent debris from falling into the carburetor, carefully remove the foam element
(C, Figure 11) from the air filter base (D).
4.
Remove the air filter (E, Figure 11).
5.
To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
6.
Remove the pre-cleaner (F, Figure 11), if equipped, from the air filter (E).
7.
Wash the pre-cleaner (F, Figure 11), if equipped, in liquid detergent and water. Allow
the pre-cleaner to thoroughly air dry. Do not oil the pre-cleaner.
