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 dam-
age due to inadequate lubrication.
Check oil level. (Oil capacity is about 20 oz. or 0.6 liters.)
Place engine level and clean around oil fill .
Remove dipstick, wipe with clean cloth
, insert and
tighten down again. Remove dipstick and check oil
level. Oil should be at FULL mark
.
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 instructions.
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.
Before Starting (see fig. )
ALWAYS KEEP HANDS AND FEE
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.
Open fuel shut-off valve 1/4 turn counterclockwise
, if
equipped.
Primer equipped engine
Move throttle control to FAST position. Push primer
bulb
firmly 3 times before starting engine.
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.
Choke equipped engine
Move throttle control to CHOKE or START position.
Starting (see fig. )
Rewind start
Close safety brake control handle ,
if equipped. Grasp rope handle and
pull slowly
until resistance is felt.
Then pull cord rapidly to overcome
compression, prevent kickback and start engine. Re-
peat if necessary with choke (if equipped) in RUN
position and throttle in FAST. When engine starts,
operate in FAST position.
Electric start, if equipped
If equipment manufacturer has supplied battery,
charge it before trying to start engine, as equipment
manufacturer recommends.
Turn key
to START. Repeat if necessary with choke
(if equipped) in RUN position and throttle in FAST. When
engine starts, operate in FAST position.
Note: Use short starting cycles (15 seconds/ minute) to
prolong starter life. Extended cranking can damage
starter motor.
Stopping (see fig. )
Release safety brake control handle OR move throttle
control to STOP.
Turn key OFF and remove . Close fuel shut-off valve, if
equipped.
Maintenance (see fig. )
See Maintenance Schedule
Follow the hourly or calendar intervals, whichever occur
first. More frequent service is required when operating in
adverse conditions.
To prevent acci-
dental starting, re-
move spark plug
wire and ground
it before servicing,
and disconnect battery at negative terminal, if equipped.
CAUTION:If engine must be tipped to transport equip-
ment or to inspect or remove grass, keep spark plug
side of engine up
.
Transporting or tipping engine spark plug down may cause:
1. Smoking,
2. Hard starting,
3. Spark plug fouling,
4. Oil saturation of air filter.
Oil service (see fig. )
Check oil level regularly.
Be sure correct oil level is maintained. Check every 5
hours or daily, before starting engine. See oil filling
procedure under Oil Recommendations.
Change oil.
Change oil after first 5 hours of operation. Change oil
while engine is warm. Refill with new oil of recom-
mended SAE viscosity grade. (see fig.
)
Before tipping engine or equipment to
drain oil, drain fuel from tank by running
engine until fuel tank is empty.
If draining oil from top of engine, keep air cleaner
side up. Oil can be drained with spark plug side up, if
necessary.
By removing drain plug
with a ratchet and square
extension
, oil can be drained from engine bottom.
Air cleaner service (see fig. )
Replace if very dirty or damaged.
Wash pre-cleaner in liquid detergent and water. Allow
to dry thoroughly before using. Do not oil pre-cleaner.
Clean cartridge by tapping gently on a flat surface. Do
not use petroleum solvents, e.g., kerosene, which will
cause cartridge to deteriorate. Do not use pressurized
air, which can damage cartridge. Do not oil cartridge.
Flat Air cleaner
1. Loosen screw and tilt cover .
2. Carefully remove pre-cleaner
(if equipped)
and cartridge assembly
from cover.
3. After servicing pre-cleaner and cartridge, place
pre-cleaner (arrows in direction shown) with
bottom lip
under cartridge pleats . Install
cartridge and pre-cleaner in cover.
4. Insert tabs on bottom of cover into slots in bottom
of base
. Tilt cover up and tighten screw
securely to base.
