In colder weather, the engine will take longer to begin
running smoothly with the choke open.
Do not operate the equipment until the choke is fully open.
STOPPING
To stop the engine turn the switch to the STOP position.
ENGINE BREAK-IN
For top engine performance, new or rebuilt engines require a break-
in period to obtain the ideal fi tting of internal moving metal parts. To
break-in the engine:
1. Run the engine at 2500 rpm, without a load, for 10 minutes.
2. Run the engine at 3,000 rpm for 10 minutes.
3. Run the engine at 3,600 rpm for 10 minutes.
4. Run the engine with a load of 8HP at 3,600 rpm for 30 minutes.
5. Run the engine with a load of 16HP at 3,600 rpm for 30 minutes.
Frequently check for oil leaks during break-in.
After the fi rst 20 hours of normal operation, change the oil and oil fi lter.
Refer to
Maintenance for procedures.
OPERATING IN DUSTY CONDITIONS
1. Keep the engine cooling fi ns and fl ywheel air inlet screen clean.
2. Perform air cleaner maintenance more often than normal-as
required.
3. Change the engine oil and oil fi lter more often than normal.
HOT AND COLD WEATHER PRECAUTIONS
Hot Weather
Pay particular attention to the following items when operating the
engine in temperatures above 100°F (38°C):
1. Keep the fl ywheel air inlet screen and cylinder cooling fi ns clean.
Make sure that nothing obstructs air fl ow to and from the engine
2. Check the oil level more frequently.
3. Change the oil and oil fi lter more often than normal.
4. Make sure the engine oil viscosity is appropriate for the ambient
temperatures and change the oil if necessary.
Cold Weather
Pay particular attention to the following items when operating the
engine in temperatures blow freezing:
1. Make sure the engine oil viscosity is appropriate for the ambient
temperatures and change the oil if necessary. If the temperature
drops before you have the chance to change the oil, warn the
engine by moving the equipment into a heated space before
attempting to start the engine or change the oil.
3. After the engine starts, slowly push the choke to the full-
open position. Pull it back, if necessary, to keep the engine
running smoothly until the engine is at operating temperature
