FUEL CAP
Your engine may be equipped with a Fresh Start fuel cap Ê.
Fresh Start fuel cap is designed to hold a cartridge Ë which contains fuel stabilizer. Fuel
stabilizer is essential in engines stored over 30 days to prevent gum from forming in fuel
system or on essential carburetor parts.
1. Place silver foil seal end of cartridge into fuel cap. Ì
2. Press to "snap" cartridge into place. Í
3. Remove the white tab to expose membrane. Î
4. Reinstall fuel cap on engine fuel tank. Ï
5. Check periodically - if empty, remove and replace.
6. Store unopened cartridges in a cool, dry, well‐ventilated area. Keep open cartridge in fuel
cap, and fuel cap closed on fuel tank when not in use.
DANGER
Fresh Start® fuel cap cartridge contents are HARMFUL OR FATAL IF
SWALLOWED.
Avoid contact to eyes, skin, or clothing. Do not take

BEFORE STARTING

WARNING
Always keep hands and feet clear of equipment moving parts.
WARNING
Do not use a pressurized starting fluid. Vapors are flammable.
• Start, store and fuel equipment in level position.
• Check oil level.
Engine models vary. There are three variations to choose before starting your engine. How
your engine is equipped will determine which steps to follow. The variations are ReadyStart
where the engine has only a throttle control, Primer equipped which means your engine
does not have a choke control, and Standard starting where your engine is equipped with
both primer and choke control. Know your engine before starting.
EQUIPPED ENGINES
1. Move throttle control to FAST Ê position. (if equipped)
2. See STARTING section.
PRIMER EQUIPPED ENGINE
1. Move throttle control to FAST Ê position.
2. Locate the primer bulb Ë and push firmly 5 times the FIRST TIME you start a new engine.
For all future starts push primer bulb 3 times. Pressing the primer too many times can
flood the engine with fuel, and the engine may not start.
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 re‐
quire priming to be repeated.
3. See STARTING section.
STANDARD ENGINE
1. Open fuel shut‐off valve1/4 turn, if equipped. Ê
2. Move throttle control to FAST or START position, if equipped. Ë
3. Move choke to RUN position, if equipment has this control.

For all future starts push primer bulb 3 times. Pressing the primer too many times can
flood the engine with fuel, and the engine may not start.
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 re‐
quire priming to be repeated.
5. See STARTING section.
STARTING
REWIND STARTER
1. Close safety brake control handle Ê on equipment with this feature. Slowly pull cord Ë
until you feel resistance, then pull quickly. Repeat if necessary. When engine starts,
operate with throttle in FAST position.
2. If engine does not start after 3 pulls, push primer bulb 3 times and pull starter again.
3. Repeat if necessary with choke (if equipped) in RUN position and throttle in FAST.
internally. Avoid
4. When engine starts, operate in FAST position.
ELECTRIC START, IF EQUIPPED
Fuel stabilizer is
1. If equipment manufacturer has supplied battery, charge it before trying to start engine, as
equipment manufacturer recommends.
2. Turn key to START.
3. Repeat if necessary with choke (if equipped) in RUN position and throttle in FAST.
4. 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
Engine models vary. If equipped, follow one or more of the steps listed.
1. Release safety brake control handle.
2. Move throttle control to STOP.
3. Push stop switch to OFF.
4. Close fuel shut‐off valve.
CAUTION: DO NOT move choke control to CHOKE position to stop engine. Backfire or
engine damage may occur.
MAINTENANCE
Fig. 5
Regular maintenance improves performance and extends engine life. More frequent service
is required when operating in adverse conditions.
To prevent accidental starting, remove spark plug wire Ê and keep it away from spark
plug before servicing. Do not strike the flywheel with hammer or hard object. If done,
the flywheel may shatter during operation. Do not tamper with links or other parts to
increase engine speed.

If engine must be tipped to transport equipment or to inspect or remove grass, keep
spark plug side of engine UP Ë. Start, store and fuel equipment in level position.
