WARNING

SPECIFICATIONS

Model 074002 air compressors are powered by a single cylinder, overhead valve (OHV), air cooled,low emissions engine.

In the State of California, these air compressor engines are certified by the California Air Resources Board to meet emissions standards for 250 hours. Such certification does not grant the purchaser, owner or operator of this engine any additional warranties with respect to the performance or operational life of this engine.The engine is warranted as stated on pages 26 and 27.

Power Ratings

* The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive 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 environmental 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, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, 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 above listed codes.

General Recommendations

Regular maintenance will improve the performance and extend the life of the air compressor.

The air compressor’s warranty does not cover items that have been subjected to operator abuse or negligence.To receive full value from the warranty, the operator must maintain the air compressor as instructed in this manual.

Some adjustments will need to be made periodically to properly maintain your air compressor. See any authorized Briggs & Stratton Power Products dealer for service.

All service and adjustments should be made at least once annually. Follow the requirements listed in MAINTENANCE SCHEDULE on page 14.

NOTE: Once a year you should clean or replace the spark plug and replace both the engine and pump air filters.A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.

Emissions Control

Maintenance, replacement or repair of emissions control devices and systems may be performed by any non-road engine repair establishment or individual. See EMISSIONS CONTROL SYSTEM, on page 26.

Maintenance

Maintenance consists of keeping the air compressor clean. Store the unit in a clean, dry environment where it will not be exposed to excessive dust, dirt, moisture or corrosive vapors. Cooling air fins on the air compressor’s engine must not become clogged with dirt, leaves or any other foreign material.

NOTE: DO NOT use a garden hose jet or flammable liquids to clean air compressor’s engine.Water can enter engine fuel system and cause problems.

Cleaning Unit

To prolong compressor life, perform these steps weekly. If the operating environment is particularly dirty, clean unit daily.

1. With spark plug disconnected, use a soft cloth and a

small brush for cleaning accumulated dirt and debris from the following locations:

• Cooling fins on top and sides of Air Compressor Pump, and engine blower housing slots (see Figure 13).

• Oil fill locations and adjacent areas on both Air Compressor Pump housing and Engine

• Oil drain plugs and adjacent areas on both Air Compressor Pump housing and Engine

Inspect Engine Oil Level

Oil Recommendations NOTE:When adding oil to the engine crankcase, use only

high quality detergent oil rated with API service classification SF, SG, SH, SJ or higher. DO NOT use special additives.

1. Choose a viscosity according to the table below:

* The use of multi-viscosity oils (5W-30, 10W-30, etc.) in temperatures above 40°F (4°C) will result in higher than normal oil consumption. Inspect oil level more often when using a multi-viscosity oil.

** The use of SAE 30 oil in temperatures below 40°F (4°C) will result in hard starting and possible engine bore damage due to inadequate lubrication.

NOTE: Synthetic oil meeting ILSAC GF-2, API certification mark and API service symbol with “SJ/CF ENERGY CONSERVING” or higher, is an acceptable oil for use at all temperatures. Use of synthetic oil does not alter required oil change intervals.

Inspecting Engine Oil Level

Inspect oil level prior to each use or at least every 8 hours of operation. Keep oil level maintained.

1. Make sure unit is on a level surface.

2. Remove Oil Fill Cap and wipe clean with cloth.

3. Verify oil is at the point of overflowing at oil fill opening.

10. Protect air hose(s) from damage (such as being stepped on or driven over).

Long Term Storage Instructions

It is important to prevent gum deposits from forming in essential fuel system parts, such as the carburetor, fuel filter, fuel hose or tanks during storage.Also, experience indicates that alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage.Acidic fuel can damage the fuel system of an engine while in storage.

Fuel Additive:

If using a fuel additive, fill the Fuel Tank with fresh fuel. If only partially filled, air in the Fuel Tank will promote fuel deterioration during storage. Engine and fuel can be stored up to 24 months with additive.

• Add fuel additive following manufacturer’s instructions.

Figure 21 — Spark Plug

STORAGE

• Run engine outdoors for 30 seconds to be sure that treated fuel has replaced untreated fuel in the carburetor.

If fuel additive is not used, remove all fuel from Fuel Tank and run engine until it stops from lack of fuel.

Change Oil

While engine is still warm, drain oil from crankcase (see Page 17). Refill with recommended grade oil.

Oil Cylinder Bore

• Remove spark plug and pour about 1 ounce (30ml) of clean engine oil into the cylinder.

• Install spark plug and pull starter handle slowly to distribute oil.

Other Storage Tips

1. DO NOT store fuel from one season to another.

2. Replace fuel can if it starts to rust. Contaminated fuel will cause engine problems.

3. If possible, store unit indoors and cover it to give protection from dust and dirt. BE SURE TO EMPTY FUEL TANK.

4. Cover unit with a suitable protective cover that does not retain moisture.

5. Store air compressor on a level surface in clean, dry, nonfreezing indoor location.

WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK

• Store away from furnaces, stoves, water heaters, clothes dryers or other appliances that have pilot light or other ignition source because they can ignite fuel vapors.

WHEN DRAINING FUEL

• Turn air compressor OFF and let it cool at least 2 minutes before removing FuelTank Cap. Loosen cap slowly to relieve pressure in tank.

• Drain Fuel Tank outdoors.

• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.

• DO NOT light a cigarette or smoke.

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

WARNING

• NEVER pull starter handle with spark plug removed.

Unintentional sparking can result in fire or electric shock.

WARNING

• DO NOT place a storage cover over a hot air compressor.

• Let equipment cool for a sufficient time before placing the cover on the equipment.

GLOSSARY

Becoming familiar with these terms will help you understand and operate most air compressors:

Air Delivery – A combination of psi and CFM.The air delivery required by a tool or accessory is stated as “’number’ (S)CFM at ‘number’ psi”. For example “9.0 CFM at 90 psi”.The combination of these values dictates the required air compressor capacity.

Air Tank Capacity – The volume of air stored in the tank and available for immediate use.

Alternating Current (AC) - Voltage that increases to a maximum positive value (+) and falls back to zero and then continues to a maximum negative value (-) and back to zero. This cycle is repeated 60 times each second for 60 hertz AC power.

ASME Certified - Indicates that the pressure vessel (air tank) and related components are manufactured, tested, and inspected to the specifications set by the American Society of Mechanical Engineers.

ASME Safety Valve - A protection device that automatically releases tank air if the air contained within exceeds a preset maximum rating.

Cast Iron Sleeve - A thin iron cylinder cast into the cylinder head, producing a harder surface between the aluminum cylinder walls and steel piston rings, thus extending the life of the compressor.

CFM or SCFM (Standard Cubic Feet per Minute). SCFM is the volume of air, in cubic feet, that the compressor can pump in one minute at a specific working pressure.The term CFM is used in this manual.

Circuit Breaker - A thermal switch that opens a circuit if too much current is passing through it.The air compressor engine is protected by this resettable device.

Cut-In Pressure – As air is taken from the air tank, the tank air pressure drops.At a certain low level, the Pressure Switch senses this low pressure and causes the compressor engine to go from idle to full speed, thus refilling the air tank.The level at which the engine switches ON is called the Cut-In Pressure.

Cut-Out Pressure – While the compressor is running, air is being produced and stored in the air tank. If no air is being used, air pressure will build in the tank.The Pressure Switch senses this high pressure and at a certain high level, it slows the compressor engine to idle speed.The level at which the engine switches OFF is called the Cut-Out Pressure.

Duplex Receptacle - Two 120 volt AC receptacles that are tied together. Similar to common household outlets.

GFCI - Ground fault current interrupter.A device that will sense current flow in the milliamp range in a power circuit to ground conductor and activate a relay to open both line conductors.

Ground - A connection, either intentional or accidental, between an electric circuit and the earth or some conducting body serving in place of the earth.

Pressure Control – Often called a regulator, this device is used to adjust the air compressor’s pressure output.The Pressure Control is adjusted to supply the psi value required by certain air tools, as monitored on the Outlet Pressure Gauge.

psi - pounds per square inch.The measure of air pressure delivered by the air compressor system.

Single Stage - Single stage refers to an air compressor with one or more cylinders that take air in each cylinder at the down stroke and compresses the air into the air tank on the up stroke.

Tank Pressure Gauge – A device used to indicate the air pressure contained in the air tank, in psi

Two Stage - A two-stage compressor always has a minimum of two cylinders - a low pressure (LP) cylinder (largest) and an high pressure (HP) cylinder (smallest).As the LP piston goes downward, air is taken in at atmospheric pressure; on the upward stroke the LP piston discharges the air through an intercooler and into the HP cylinder on its downward stroke. On the upward stroke of the HP piston the air is discharged into the air tank.Two-stage compressors are recommended when tool usage is continuous.

Vibration Isolators – When installed, are designed to minimize vibrations produced by the air compressor.
