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.
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 vis
cosity 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 (approximate capacities)

Place engine level and clean around oil fill
Remove dipstick and wipe with clean cloth. Insert
dipstick in oil fill - tighten down if high oil fill
Ì
not tighten down if low oil fill - remove dipstick to
check oil level. Oil should be at FULL mark
If oil is required, add slowly. Do not over fill. Tighten
dipstick firmly before starting engine.

Fuel Recommendations


(see fig. )
THE GASOLINE ENGINE IS CERTIFIED TO OPER
ATE ON GASOLINE. Exhaust Emission Control Sys
tem: EM (Engine Modifications).
Use clean, fresh, lead free gasoline with a minimum of
85 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.
THE MODEL 1844 ENGINE IS CERTIFIED TO OPER
ATE ON LPG / NG FUEL.
Use clean, dry fuel, free of moisture or any particulate
material. Using fuels outside the following recom
mended values may cause performance problems.
In engines set up to run on LPG, commercial grade
HD5 LPG is recommended. Recommended fuel com
position is fuel with a minimum fuel energy of 2500
3
BTU's/ft with maximim propylene content of 5% and
butane and heavier gas content of 2.5% and minimum
propane content of 90%.
Check fuel level - Gasoline Engines.
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.

BEFORE STARTING - LPG / NG Engines.

(see fig. )
The LPG / NG mixer is equipped with solenoid
Ë Ì
inlet , 12 volt connector , and equipped for a fuel
Í
lock off valve .
CAUTION:
All LPG / NG fuel mixers are equipped with a
Ê
solenoid .
When operating on LPG fuel, 12 volts MUST be
Ì
supplied to connector .
When operating on NG fuel, 12 volts MUST NOT be
Ì
supplied to connector .

STARTING (see fig. )
1. On gasoline engine, move choke control
CHOKE position. On LPG/NG engine, open fuel
shut off valve.
Ë
2. Move throttle control to FAST position.
Ì
3. Turn fuel shut off valve on, if equipped on
gasoline engine.
Í
4. Move stop control to ON position, if equipped.
Rewind starter, if equipped (see fig.
Grasp rope handle and pull slowly until
resistance is felt. Then pull cord rapidly
to overcome compression, prevent
kickback and start engine. Repeat if
necessary with choke in RUN position and throttle in
FAST. When engine starts, operate in FAST position.
Electric starter, if equipped (see fig.
On engines equipped with 12 volt starting systems, turn
Ê
key to START position. Repeat if necessary with
throttle control in FAST position. When engine starts,
operate in FAST position.
Note: If equipment manufacturer has supplied battery,
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

(see fig. )
Do not move choke control to CHOKE position to stop
engine. Backfire or engine damage may occur. Move
Ê
throttle control to IDLE or SLOW position, if
Ë
equipped. Then turn key to OFF or move stop
Ì
control to OFF position. Close fuel shut off valve
Note: Always remove key from switch when equipment
is not in use or left unattended.
Note: When engine is transported, close fuel shut off
valve to prevent leakage.
