Before Operation
PRE-OPERATION CHECKS
For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the
engine to check its condition. Be sure to take care of any problem you nd, or have your servicing dealer correct it, before you operate
the engine.
Improperly maintaining this engine or failing to correct a problem before operation, could cause a
malfunction in which you could be seriously injured.
Always perform a pre-operation inspection before each operation and correct any problem.
Before beginning your pre-operation checks, be sure the engine is level and the engine switch is in the STOP position.
Check the General Condition of the Engine
• Remove any excess dirt or debris, especially around the heat shield, recoil starter, and cylinder head ns.
• Inspect for signs of damage and oil leakage.
• Be sure all shields and covers are in place. All nuts, bolts, and screws must be tight.
Check the Engine
• Check the engine oil level. Running the engine with a low oil level or improper oil can cause engine damage. To avoid the
inconvenience of an unexpected shutdown, always check the engine oil on a level surface before startup. Engine may be shipped
with or without oil. 5W-30 oil is recommended for general use. Synthetic oil is an acceptable alternative (refer to Engine Oil Level
Check in contents for proper engine oil levels).
• Check the fuel level before start-up. Since the engine must be cool before refueling, starting with a full tank will help to eliminate or
reduce operating interruptions for refueling.
Electric Start
• Determine what type of power source outlet you will be connecting the power cord to. If the starter is equipped with a 120V AC
electrical requirement, make sure to use the appropriate 120V AC household current input. For European 230V AC applications,
use the appropriate grounded extension lead and power source.
• Determine if your power source has a Ground Fault Interrupt (GFI) three-wire system by consulting with a licensed electrician.
If your power source does not have a GFI three-way ground system, DO NOT USE THE ELECTRIC STARTER due to a possible
hazardous condition.
Check all Equipment Powered by this Engine
Review the instructions provided with the equipment powered by this engine for all precautions and procedures that should be
followed before starting the engine.
SAFE OPERATING PRECAUTIONS
Review the instructions provided with the equipment powered by this engine for any safety precautions that should be observed in
conjunction with starting, shutting down, or operating the engine.

STORING YOUR ENGINE
Storage Preparation
Proper storage preparation keeps your engine trouble-free and clean. The following steps will assist in keeping rust and corrosion from
impairing your engine’s function and appearance, and will make the engine easier to start when using again.
Cleaning
If the engine has been running, allow it to cool for at least half an hour before cleaning. Clean all exterior surfaces and apply a light lm
of spray penetrating lubricant.
• Do not spay water directly into the exhaust ports or into heat shield openings. Water that passes through these areas can cause
damage to the engine. Use a rag to wipe down heat shield if cleaning is required.
• Water contacting a hot engine can cause damage. If the engine has been running, allow it to cool for at least half an hour before washing.
Adding a Fuel Stabilizer to Extend Fuel Storage Life
• NOTICE
Fuel stabilizer is recommended for long term storage.
1. Turn the red fuel knob to the OFF position while engine is running and allow the engine to run until it stops. Turn engine OFF when
it begins surging to avoid engine damage.
2. Add fuel stabilizer, following the manufacturer’s instructions.
3. Turn the red fuel knob to the ON position after adding fuel stabilizer.
4. Re-start engine.
5. Run the engine outdoors for 1 minute to be sure that treated gasoline has replaced the untreated gasoline in the carburetor.
6. Slow the engine to an idle speed.
7. Repeat step 1 above.
MAINTENANCE SCHEDULE
Normal Operating Conditions (less than 40 hrs. per year)
* Spark plug gap to be set to 0.027 - 0.030 inches.
Extreme Operating Conditions (greater than 40 hrs. per year)
* Spark plug gap to be set to 0.027 - 0.030 inches.

STORAGE PRECAUTIONS
If your engine will be stored with gasoline in the fuel tank and in the carburetor, there is the possible hazard of gasoline vapor ignition.
Choose a well-ventilated storage area away from heat, sparks, ames, and any appliance that operates with a ame such as a
furnace, water heater, or clothes dryer. Avoid any area with a spark-producing electric motor, garage door openers, or where power
tools are operated.
Avoid storage areas with high humidity which causes rust and corrosion. Leave the red fuel knob in the OFF position to reduce the
possibility of fuel leakage.
Position the equipment so the engine is level to avoid fuel or oil leakage. When the engine and exhaust system are cool, cover the
engine to keep out dust. A hot engine and exhaust system can ignite or melt certain materials. Do not use sheet plastic as a dust
cover. A nonporous cover can trap moisture around the engine causing rust and corrosion.
Removal From Storage
Check your engine as described in the BEFORE OPERATION chapter of this manual. If refueling is required, only use fresh gasoline.
TRANSPORTING
Transport only when engine is cool. A hot engine and exhaust system can burn you and can ignite some materials. Keep the engine
level when transporting to reduce the possibility of fuel leakage. Position the red fuel knob to the OFF position. Secure the engine to
prevent movement during transporting to prevent potential injury and damage to the engine.
EMISSION CONTROL SYSTEM INFORMATION
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish written instructions describing the operation and maintenance of
emission control systems.
The following instruction and procedures must be followed in order to keep the emissions from your engine within the emission
standards.
Tampering and Altering
Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those acts that
constitute tampering are:
• Removal or alteration of any part of the intake, fuel or exhaust systems.
• Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside its design
parameters.
