Air Compressor Operating Location

Clearances and Air Movement

Place air compressor outdoors in an area that will not accumulate deadly exhaust gas. DO NOT place air compressor where exhaust gas (A) could accumulate and enter inside or be drawn into a potentially occupied building. Ensure exhaust gas is kept away from any windows, doors, ventilation intakes, or other openings that can allow exhaust gas to collect in a confined area. Prevailing winds and air currents should be taken into consideration when positioning air compressor.

The air compressor pump is designed to allow for proper cooling. The ventilation openings on the compressor are necessary to maintain proper operating temperature. DO NOT place rags or containers on or near these openings. Keep the air filter clear of obstructions that could reduce airflow to the air compressor.

Operate the air compressor with unit located on a flat surface to ensure that it receives proper lubrication.

Break-In Procedure

Before first use of this equipment, the system must undergo a break-in operation, as described in this section.

1. Open both drain valves (rotate fully counterclockwise) to prevent air pressure build-up in air tank during break-in period.

NOTE: Always drain air tank over a washable surface or in a suitable container to prevent damaging or staining surfaces.

2. Start your air compressor following steps 1 through 7 in the section Starting Your Air Compressor.

3. Run compressor for 15 minutes. Make sure start valve and drain valves remain open.

4. After 15 minutes, with air compressor running, close start valve (flip pin down to a horizontal position) and both drain valves (rotate fully clockwise). Air tanks will fill to “cut-out” pressure and engine speed will slow to idle.

NOTE: If you hear leaking air, pull quick connect coupler back until it clicks to reset coupler valve.

5. Turn your air compressor off as described in Stopping Your Air Compressor.

NOTE: Check oil level in compressor after break-in. The compressor has completed the break-in procedure and

If necessary, modify the schedule to suit the conditions under which you use your compressor. Modifications will depend upon hours of operation and working environment. Operating air compressors in extremely dirty or hostile environments will require more frequent maintenance checks.

NOTE: See Features and Controls and Operation for control locations.

Regular maintenance will improve the performance and extend the life of the air compressor. See any authorized Briggs & Stratton dealer for service.

The air compressors 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 air compressor as instructed in this manual.

Some adjustments will need to be made periodically to properly maintain your air compressor.

All service and adjustments should be made at least once each season. Follow the requirements in the Maintenance Schedule chart above.

NOTE: Once a year you should clean or replace the spark plug and replace the air filter. 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 the emissions

control devices and systems may be performed by any non-road engine repair establishment or individual.

However, to obtain ”no charge” emissions control service, the work must be performed by a factory authorized dealer. See the Emissions Warranty.

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 tank 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.

Protect Fuel System

Fuel Additive:

Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs & Stratton FRESH START™ fuel stabilizer, available as a liquid additive or a drip concentrate cartridge.

There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel system. The engine and fuel can then be stored up to 24 months.

If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.

Change Engine Oil

While engine is still warm, drain oil from crankcase. Refill with recommended grade. See Changing Engine Oil in Engine Maintenance.

Oil Cylinder Bore

• Remove spark plug and pour about 1/2 ounce (15 ml) 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 unless it has been treated as described in Protect Fuel System.

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

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

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 motor 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 turns-on the compressor motor, thus refilling the air tank. The level at which the motor 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 turns the compressor motor off. The level at which the motor 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 regulated 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.

Emission Information

Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emission Standards must display information regarding the Emissions Durability Period and Air Index. The engine manufacturer makes this information available to the consumer on emission labels. The engine emission label will indicate certification information.

The Emissions Durability Period describes the number of hours of actual running time for which the engine is certified to be emissions compliant, assuming proper maintenance in accordance with the Operating & Maintenance Instructions. The following categories are used:

Moderate: Engine is certified to be emission compliant for 125 hours of actual engine running time.

Intermediate: Engine is certified to be emission compliant for 250 hours of actual engine running time.

Extended: Engine is certified to be emission compliant for 500 hours of actual engine running time.

For example, a typical walk-behind lawn mower is used 20 to 25 hours per year. Therefore, the Emissions Durability Period of an engine with an intermediate rating would equate to 10 to 12 years.

Certain engines will be certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 emission standards. For phase 2 certified engines, the Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emission requirements.

For engines less than 225 cc displacement: Category C = 125 hours Category B = 250 hours Category A = 500 hours.

For engines of 225 cc or more displacement: Category C = 250 hours Category B = 500 hours Category A = 1000 hours.

The warranty period begins on the date of purchase by the first retail consumer or commercial end user, and continues for the period of time stated above. “Consumer use" means personal residential household use by a retail consumer. “Commercial use" means all other uses, including use for commercial, income producing or rental purposes. Once equipment has experienced commercial use, it shall thereafter be considered as commercial use for purposes of this warranty.

ABOUT YOUR WARRANTY

We welcome warranty repair and apologize to you for being inconvenienced. Any Authorized Service Dealer may perform warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example, warranty service would not apply if equipment damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation. Similarly, the warranty is void if the manufacturing date or the serial number on the air compressor has been removed or the equipment has been altered or modified. During the warranty period, the Authorized Service Dealer, at its option, will repair or replace any part that, upon examination, is found to be defective under normal use and service. This warranty will not cover the following repairs and equipment:

• Normal Wear: Outdoor Power Equipment, like all mechanical devices, needs periodic parts and service to perform well. This warranty does not cover

repair when normal use has exhausted the life of a part or the equipment.

• Installation and Maintenance: This warranty does not apply to equipment or parts that have been subjected to improper or unauthorized installation or

alteration and modification, misuse, negligence, accident, overloading, overspeeding, improper maintenance, repair or storage so as, in our judgment, to adversely affect its performance and reliability. This warranty also does not cover normal maintenance such as air filters, adjustments, and so forth.

• Other Exclusions: This warranty excludes wear items such as seals and o-rings, etc.This warranty also excludes air compressors that have been run

without oil or subjected to freezing with water in the tank(s). This air compressor is warranted for non-continuous use and should not be subjected to continuous operation. Accessory parts, such as hoses or air tools not supplied with the compressor are excluded from the product warranty. This warranty excludes failures due to acts of God and other force majeure events beyond the manufacturers control. 203939E, Rev. -, 7/1/2007
