not to overfill.

Starting
(see figs. )
ALWAYS KEEP HANDS AND FEET
CLEAR OF EQUIPMENT MOVING PARTS.
Do not use a pressurized starting
fluid. Vapors are flammable.
Start, store and fuel lawn mower in level position. Start
lawn mower on hard surface or over previously cut
grass.
Check oil level.
Open fuel shut‐off valve, if equipped.

Before starting engine (see fig.
If engine runs low on oil, an oil pressure switch (if
engine is equipped) will activate a warning light. (Read
the operating instructions supplied by the equipment
manufacturer.) See Oil pressure.
1. Open fuel shut‐off valve, if equipped.
2. Move choke control to CHOKE position
Note: If engine does not start, remove air cleaner to check
choke. Choke must fully close. If not, see Adjustments.
Ë
3. Move throttle control to FAST position.

Electric starter (see fig. )
Ê
Turn key to START position or press button
Repeat if necessary with choke off and throttle control
in FAST position. Operate engine with choke off and
throttle in FAST position.
Note: If equipment manufacturer has supplied battery,
charge it before trying to start engine, as equipment
manufacturer recommends. Use short starting cycles
(15 secs. per min.) to prolong starter life. Extended
cranking can damage starter motor.
CAUTION:If engine is equipped with battery for electric
starter, do not operate engine with battery disconnected.

Stopping
(see fig. )
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
Ë
turn key to OFF .
Always remove key from switch when equipment is not
in use or left unattended.
When engine or equipment is trans‐
ported, close fuel shut‐off valve, if
equipped, to prevent fuel leakage.

Maintenance
Also, see Maintenance Schedule. Follow the hourly or
calendar intervals, whichever occur first. More frequent
service is required when operating in adverse conditions.
See any Authorized Briggs & Stratton Dealer for correct
replacement parts.
connect battery at negative terminal, if equipped.
Oil service (see fig.
Check oil level regularly.
Be sure correct oil level is maintained. Check every 8
hours or daily, before starting engine. See oil filling
procedure, Oil Recommendations.
Change oil.
Change oil after first 8 hours of operation. Change oil
while engine is warm. Refill with new oil of recom‐
mended SAE viscosity grade. (see fig.
Ë
Change oil filter
Replace oil filter after every 100 hours of operation or
every season, whichever occurs first. Before installing
new filter, lightly oil filter gasket with fresh, clean engine

oil. Screw filter on by hand until gasket contacts oil filter
adapter. Tighten 1/2 to 3/4 turn more. Start and run
engine at IDLE to check for oil leaks. Stop engine.
Recheck oil level and add oil if required.
Oil pressure
Ê
.
If oil pressure drops below 4‐6 psi (.2‐.4 kg/cm
pressure switch (if engine is equipped) will either
activate a warning device or stop the engine. Check oil
level with dipstick. If oil level is between ADD and FULL
mark on dipstick, do not try to restart engine. Contact an
Authorized Briggs & Stratton Service Dealer. Do not
operate engine until oil pressure is corrected.
Ë
.
If oil level is below ADD mark on dipstick, add oil to bring
level to FULL mark. Restart engine and check oil
pressure. If pressure is normal, continue to operate
engine.
Note: Oil pressure gauge, if engine is equipped, is
supplied by manufacturer of equipment.

Maintenance Cont'd
Air cleaner, dual element
Replace pre‐cleaner or cartridge if very dirty or damaged.
To service pre‐cleaner, wash in liquid detergent and
water. Squeeze dry in a clean cloth. Saturate in engine
oil. Squeeze in clean, absorbent cloth to remove
excess oil.
1. See illustrations (see fig. ) for disassembly
and reassembly of your air cleaner style.
2. Carefully remove air cleaner cartridge and pre‐
cleaner, preventing debris from entering carbure‐
tor.
3. Install pre‐cleaner (if equipped) in base with
mesh side up.
4. Install cartridge on pre‐cleaner.
5. Replace cover. To ensure proper fit, tabs must be
hooked into slots. Tabs are painted a different
color in some instances.
6. Latch handle or tighten knobs completely to
secure cover.
CAUTION: Improper installation of air cleaner
cover may cause damage to engine.
