IN THE INTEREST OF SAFETY, 00 NOT RUN ENGINE AT EXCESSIVE SPEEDS
Operating an engine at excessive speeds increases the hazard of personal injury. DO NOT TAMPER WITH PARTS WHICH MAY
INCREASE THE GOVERNED SPEED.
For rotary lawnmower safety, USA Standard Safety Specifications for Power Lawn Mowers specify a maximum blade tip speed
of 19,000 feet per minute, primarily to reduce the hazard from thrown objects.
Rotary lawnmower manufacturers select the governed top speed of the engine based on the length and design of the cutter
blade and design of other mower parts.
All rotary lawnmowers should be checked for conformance to the USA Standard Safety Specifications for Power Lawn Mowers
on blade tip speed, if the engine is repaired or replaced, or if mower parts are changed.
Dirt and grass clippings, or other debris, in cooling fins or governor parts can affect engine speed. See cleaning instruc­
tions in Section 3.
CAUTIOIM
TO PREVENT ACCIDENTAL STARTING always remove the spark plug before working on the engine or equipment driven by the
engine or remove cable from spark plug and insert terminal in V-notch in cylinder head cover.
DO NOT RUN THE ENGINE IN AN ENCLOSED AREA. Exhaust gases contain carbon monoxide, an odorless and deadly poison.
DO NOT FILL GASOLINE TANK WHILE ENGINE IS RUNNING. Spilling gasoline on a hot engine may cause a fire or explosion.
