Checking the water and cleaning the radiator on tractors and other self-propelled equipment are preventive maintenance for the:

• Cooling system
• Electrical system
• Fuel system
• Lubrication system

Two simple maintenance procedures done before starting a 4-cycle engine are:

• Add antifreeze and water
• Add oil an fuel mixture
• Change spark plugs and points
• Check oil and add clean fuel

Cleaning the outside parts of a small engine is the MOST important maintenance for the:

• Cooling system
• Fuel system
• Electrical system
• Lubrication system

It is very important that dust and dirt be kept out of small engines because they do NOT have a/an:

• Amperage gauge
• Battery
• Oil filter
• Oil gauge

The primary reason for all types of preventive maintenance on tractors, equipment, and small engines is to:

• Decrease repairs
• Increase costs
• Reduce efficiency
• Increase repairs

Checking the engine oil level is a service NOT necessary for:

• 2 cycle engines
• 4 cycle engines
• Combines
• Tractors

To service an "oil filter" type air filter, the filter is washed to remove the dirt and then

• Discarded in trash can
• Oiled and squeezed
• Repaired by the technician
• Replaced with a new one

Changing the oil is the MAIN service done on a 4-cycle engine's

• Coolant system
• Electrical system
• Exhaust system
• Lubrication system

A new model small engine will NOT have:

• A piston
• A spark plug
• Pistons
• Points

When on is servicing a "dry type" air filter, the filter should be 

• Blown out
• Oiled
• Repaired
• Replaced
