Battery
A 12 volt battery is normally used. Refer to the
operating instructions of the equipment this engine
powers for specific battery requirements.
If the battery charge is not sufficient to crank the
engine, recharge the battery (see page 11).
Operating
Angle of Operation
This engine will operate continuously at angles up to
15°; 25° intermittently. Check oil level to assure
crankcase oil level is at the “F” mark on the dipstick.
Refer to the operating instructions of the equipment
this engine powers. Because of equipment design or
application, there may be more stringent restrictions
regarding the angle of operation.
NOTE: Do not operate this engine continuously at
angles exceeding 15° in any direction. Engine
damage could result from insufficient
lubrication.
Cooling
NOTE: If debris builds up on the grass screen or
other cooling air intake areas, stop the engine
immediately and clean. Operating the engine
with blocked or dirty air intake and cooling
areas can cause extensive damage due to
overheating. See Clean Air Intake/Cooling
Area, page 11.
WARNING: Hot Parts!
Engine components can get extremely hot from
operation. To prevent severe burns, do not touch these
areas while the engine is running–or immediately after
it is turned off. Never operate the engine with heat
shields or guards removed.
Engine Speed
NOTE: Do not tamper with the governor setting to
increase the maximum engine speed.
Overspeed is hazardous and will void the
engine warranty. The maximum allowable high
speed for these engines is 3960 RPM, no
load.

Maintenance, repair, or replacement of the emission control devices and systems, which are being done at
the customers expense, may be performed by any non-road engine repair establishment or individual.

WARNING: Accidental Starts!
Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine or
