Operator Safety

WARNING

Kerosene and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

WHEN ADDING FUEL

Turn engine OFF and let engine cool at least 2 minutes before removing fuel cap.

Fill fuel tank outdoors or in well-ventilatedarea.

Do not overfill fuel tank.

Keep kerosene away from sparks, open flames, pilot lights, heat, and other ignition sources.

Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.

WHEN STARTING ENGINE

Make sure spark plug, muffler, fuel cap and air cleaner are in place.

DO NOT start engine with air filter or cover not properly installed. Serious injury or death could result from backfire.

Do not crank engine with spark plug removed.

If fuel spills, wait until it evaporates before starting engine.

If engine floods, set choke to OPEN/RUN position, place throttle in FAST and crank until engine starts.

WHEN OPERATING EQUIPMENT

Do not choke carburetor to stop engine.

WHEN TRANSPORTING EQUIPMENT

Transport with fuel tank EMPTY.

WHEN STORING KEROSENE OR EQUIPMENT WITH FUEL IN TANK

Store away from furnaces, stoves, water heaters or other appliances that have pilot light or other ignition source because they can ignite fuel vapors.

WARNING

Starting engine creates sparking.

Sparking can ignite nearby flammable gases.

Explosion and fire could result.

If there is natural or LP fuel leakage in area, do not start engine.

Do not use pressurized starting fluids because vapors are flammable.

WARNING

Engines give off carbon monoxide, an odorless, colorless, poison gas.

Breathing carbon monoxide can cause nausea, fainting or death.

Start and run engine outdoors.

Do not start or run engine in enclosed area, even if doors or windows are open.

WARNING

Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go.

Broken bones, fractures, bruises or sprains could result.

When starting engine, pull cord slowly until resistance is felt, then pull rapidly.

Direct coupled equipment components such as, but not limited to, blades, impellors, pulleys, sprockets, etc., must be securely attached.

WARNING

Rotating parts can contact or entangle hands, feet, hair, clothing, or accessories.

Traumatic amputation or severe laceration can result.

Operate equipment with guards in place.

Keep hands and feet away from rotating parts.

Tie up long hair and remove jewelry.

Do not wear loose-fittingclothing, dangling drawstrings or items that could become caught.

WARNING

Running engines produce heat. Engine parts, especially muffler, become extremely hot.

Severe thermal burns can occur on contact.

Combustible debris, such as leaves, grass, brush, etc. can catch fire.

Allow muffler, engine cylinder and fins to cool before touching.

Remove accumulated combustibles from muffler area and cylinder area.

Install and maintain in working order a spark arrester before using equipment on forest-covered,grass-covered,brush-coveredunimproved land. The state of California requires this (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal land.

WARNING

Unintentional sparking can result in fire or electric shock.

Unintentional start-upcan result in entanglement, traumatic amputation, or laceration.

BEFORE PERFORMING ADJUSTMENTS OR REPAIRS

Disconnect spark plug wire and keep it away from spark plug.

Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation.

Do not tamper with governor spring, links or other parts to increase engine speed.

Use only correct tools.

WHEN TESTING FOR SPARK

Use approved spark plug tester.

Do not check for spark with spark plug removed.

5

Oil Recommendation

Use a high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. Do not use special additives.

Determine best grade for use by temperature during operation, see chart.

SAE 30 405F and higher (55C and higher)

is good for all purpose use above 40°F, use below 40°F will cause hard starting.

10W-30 0 to 1005F (−18 to 385C)is better for varying temperature conditions. This grade of

oil improves cold weather starting, but may increase oil

consumption at 80°F (27°C) or higher.

Check oil level frequently at higher temperatures.

Synthetic 5W-30 −20 to 1205F (−30 to 405C)provides the best protection at all temperatures as well as

improved starting with less oil consumption.

5W-30 405F and below (55C and below)

is recommended for winter use, and works best in cold conditions.

Oil Capacity

The engine holds approximately 5/8 qt. (20 oz; 0.6 liter).

Adding Oil

Check oil level before starting the engine.

Keep oil level at FULL.

Check level daily, or after every eight (8) hours.

1.Place engine level and clean around oil fill plug. (A)

2.Remove oil fill plug. Fill oil to point of overflowing. (B)

3.Replace plug before starting engine.

Technical Information

Power Ratings: The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision2002-05).Given both the wide array of products on which our engines are placed, and the variety of environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece of power equipment (actual“on-site”power). This difference is due to a variety of factors including, but not limited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the manner in which the engine is operated, enginerun-into reduce friction and clean out of combustion chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values derived using the foregoing codes.
