Oil Recommendations

(see fig.
Engine shipped from Briggs & Stratton without oil.
Before starting engine, fill with oil. Do not over-fill.
Use a high quality detergent oil classified "For Service
SF, SG, SH, SJ" or higher such as Briggs & Stratton
30W, Part Number 100005. Use no special additives
with recommended oils. Do not mix oil with gasoline.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
before the next oil change.
Note: Synthetic oil meeting ILSAC
GF-2, API certification mark and API ser-
vice symbol (shown at left) with "SJ/CF
ENERGY CONSERVING" or higher, is an
acceptable oil at all temperatures. Use of
synthetic oil does not alter required oil
change intervals.
Air cooled engines run hotter than automotive
*
engines. The use of non-synthetic multi-viscosity
oils (5W-30, 10W-30, etc.)in temperatures above
40° F (4° C) will result in higher than normal oil
consumption. When using a multi-viscosity oil,
check oil level more frequently.
** SAE 30 oil, if used below 40° F (4° C), will result
in hard starting and possible engine bore
damage due to inadequate lubrication.
Check oil level. (Oil capacity is about 20 oz. or 0.6 liter.)
➊
Place engine level and clean around oil fill .
➋
Remove dipstick, wipe with clean cloth , insert and
tighten down again. Remove dipstick and check oil
level. Oil should be at FULL mark ➌ .
If oil is required, add slowly. Tighten dipstick firmly
before starting engine.
Do not overfill. Overfilling with oil may cause:
1. Smoking,
2. Hard starting,
3. Spark plug fouling,
4. Oil saturation of air filter

Fuel Recommendations

Use clean, fresh, lead-free, regular gasoline with a
minimum of 77 octane. Leaded gasoline may be used if
it is commercially available and if unleaded is unavail-
able. Purchase fuel in quantity that can be used within
30 days. See Storage.
In U.S.A. leaded gasoline may not be used. Some
fuels, called oxygenated or reformulated gasolines, are
gasolines blended with alcohols or ethers. Excessive
amounts of these blends can damage the fuel system
or cause performance problems. If any undesirable
operating symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not
mix oil with gasoline.
For engine protection, we recommend using Briggs &
Stratton Fuel Stabilizer available from an Authorized
Briggs & Stratton Service Dealer.

Before refueling, allow
engine to cool 2 minutes.
Clean around fuel fill before removing cap to refuel. Fill
tank to approximately 1 inch below lowest portion of
neck to allow for fuel expansion. Be careful not to
overfill.
Starting
(see fig. ¢ )
ALWAYS KEEP HANDS AND FEET
CLEAR OF EQUIPMENT MOVING PARTS.
Do not use a pressurized starting
fluid. Vapors are flammable.
Start, store and fuel equipment in level position.
Check oil level.
Start engine first time
1. Move throttle control to FAST position.
➊
2. Push primer bulb firmly 5 times.
Close safety brake control handle
if equipped. Grasp rope handle and
pull slowly until resistance is felt. Then
pull cord rapidly to overcome com-
pression, prevent kickback and start engine. Repeat
if necessary. When engine starts, operate in FAST
position.
3. If engine does not start after 3 pulls, push primer
bulb 3 times and pull starter again.
Start engine thereafter
1. Move throttle control to FAST position.
➊
2. Push primer bulb firmly 3 times.
Close safety brake control handle
if equipped. Grasp rope handle and
pull slowly until resistance is felt. Then
pull cord rapidly to overcome com-
pression, prevent kickback and start engine. Repeat
if necessary. When engine starts, operate in FAST
position.
Note: If engine stopped because it ran out of fuel, refuel
engine and push primer bulb 3 times. Priming is usually
unnecessary when restarting a warm engine. However,
cool weather may require priming to be repeated.
Stopping
(see fig. £ )
Release safety brake control handle OR move throttle
control to STOP.

Adjustments
(see fig. ¤ )
To prevent acci-
dental starting, re-
move spark plug
wire ➊ and ground
it before adjusting.
Throttle control adjustments
Manual controls require no adjustment.
Remote throttle control
(Air cleaner not illustrated for clarity). Loosen casing
➋
clamp screw . Move governor control lever
travel in direction of arrow. Move equipment throttle
control to FAST position. Tighten casing clamp screw.
Fixed control
➍
This governor control lever was set to the equipment
manufacturer's requirements and cannot be adjusted.
Check stop switch
Move throttle control to STOP position, if so equipped.
Governor control lever ➎ must make good contact with
➏
stop switch .
Check operation of controls. Readjust if necessary.
Carburetor adjustments
The manufacturer of the equipment on which
this engine is installed specifies top speed at
which the engine will be operated. DO NOT
EXCEED this speed.
➋
,
This engine is equipped with a pulsa prime carburetor
which cannot be adjusted. Your engine will idle down
only about 300 to 600 rpm below top speed, which
accounts for the higher than expected idle speed.
