Fuel Recommendations - Briggs & Stratton 194700 Operator Owner's Manual

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 SE, SF,
SG," such as Briggs & Stratton warranty certified" SAE 30 oil
(see fig. ). Use no special additives with recommended
A
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. )
* Air cooled engines run hotter than automotive engines.
Using multi viscosity oils (10W 30, etc.) above 40° F (4°
C) will result in high oil consumption and possible engine
damage. Check oil level more frequently if using these
types of oils.
** 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
Ë
Remove dipstick , wipe with clean cloth, insert and tighten
down again. Remove dipstick and check oil level. Oil should be
Ì
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.
Do not use gasoline which contains Methanol. Do not mix oil
with gasoline.
For engine protection, we recommend using Briggs & Stratton
Gasoline Additive (see fig. ) available from an Authorized
B
Briggs & Stratton Service Dealer.
Check fuel level.
Clean around fuel fill before removing cap to refuel. Allow
space in the fuel tank for fuel expansion.
Before refueling, allow engine to cool 2 minutes.
 Starting
(see fig. )
Start, store and fuel lawn mower in level position. Start lawn
mower on hard surface or over previously cut grass.
Before starting engine (see fig.
5. Move equipment control to CHOKE or START position
Note: If engine does not start, remove air cleaner to check cho
ke. Choke must fully close. If not, see Adjustments.
6. If equipment has separate choke and throttle controls,
move throttle control to FAST position
7. Open fuel shut off valve

Electric starter (see fig.
On engines equipped with 12 volt starting systems, turn key to

FAST position. When engine starts, operate in FAST position.
Note: If equipment manufacturer has supplied battery, char
ge 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
equipped.
Always remove key from switch when equipment is not in use
or left unattended.
When engine or equipment is transported, close fuel shut off

system, before adjusting.
Choke control adjustments
Move choke control to CHOKE or START position. Remove air
cleaner to check that choke valve is closed. To assure choke
valve is closed, loosen casing clamp screw

and wire in direction of arrow to end of travel. Tighten
Ê casing clamp screw.

Check stop switch
Move throttle control to STOP position, if equipped. Governor
Í
control lever must make good contact with 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.
See an Authorized Briggs & Stratton Dealer for carburetor
adjustment.
In the U.S.A. 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
Ë
beyond limit. Finally, position idle mixture valve in middle of
, if
travel. Check idle speed and re adjust to 1750 rpm, if
necessary.
Move throttle control to FAST position. Engine should accele
rate smoothly. If it does not, adjust idle mixture valve
counterclockwise 1/8 turn.
