Oil Recommendations

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 (20 oz.) or 100028 (48 oz.).
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. (see fig.
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 (see fig. )
Oil capacity of Model Series 190000 is about 1.1 liters
(36 ounces). Oil capacity of Model Series 280000 is
about 1.4 liters (48 ounces).
Place engine level and clean around oil fill

level. Oil should be at FULL mark
If oil is required, add slowly. Tighten dipstick firmly
before starting engine.

Fuel Recommendations

Use clean, fresh, lead−free gasoline with a minimum of
77 octane. Leaded gasoline may be used if it is
commercially available and if unleaded is unavailable.
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.
Check fuel level.
Before refueling, allow
engine to cool 2 minutes.
Clean around fuel fill before removing cap to refuel. Fill
tank to approximately 1−1/2 inches below top of neck to
allow for fuel expansion. Be careful not to overfill.
 Starting
(see fig. )
Start, store and fuel lawn mower in level position. Start
lawn mower on hard surface or over previously cut grass.
Check oil level.

charge it before trying to start engine, as equipment
manufacturer recommends.
Note: Use short starting cycles (15 secs. per min.) to
prolong starter life. Extended cranking can damage
starter motor.
Stopping
Do not move choke control to CHOKE to stop engine.
Backfire or engine damage may occur. Move throttle
control to IDLE or SLOW position, then to STOP

Always remove key from switch when equipment is not
in use or left unattended.

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.
See an Authorized Briggs & Stratton Dealer for
carburetor adjustment.
The carburetor on this engine is low emission. It is
equipped with an idle mixture valve with a limiter (see
inset), which allows some adjustment, and an idle
speed adjustment screw.
Start engine and warm up approximately 5 minutes
before adjusting. With engine running, place throttle
control in SLOW position. Rotate carburetor throttle
lever against the idle speed screw and hold it. Turn idle
speed screw to obtain 1750 rpm.
Rotate idle mixture valve full travel clockwise and then
counterclockwise. DO NOT remove limiter cap. DO
NOT force beyond limit. Finally, position idle mixture
valve in middle of travel. Check idle speed and
re−adjust to 1750 rpm, if necessary.
or
Move throttle control to FAST position. Engine should
accelerate smoothly. If it does not, adjust idle mixture
valve counterclockwise 1/8 turn.
