Engine Information

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

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-covered unimproved 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.

TECHNICAL INFORMATION

POWER RATINGS: The power ratings for an individual engine model are initially developed by starting with SAE (Society of Auto- motive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002-05). Given both the wide array of products on which our engines are placed, and the variety of en- vironmental 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, tempera-

SAFETY

WARNING

Unintentional sparking can result in fire or electric shock.

Unintentional start-up can result in en- tanglement, traumatic amputation, or lac- eration.

BEFORE PERFORMING ADJUSTMENTS OR REPAIRS

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

•Disconnect battery at negative terminal (only engines with electric start).

WHEN TESTING FOR SPARK

•Use approved spark plug tester.

•Do not check for spark with spark plug removed.

ture, barometric pressure, humidity, fuel, engine lubrication, maxi- mum governed engine speed, individual engine to engine variabil- ity, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to 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.
