Operating Instructions and Parts Manual

Installation (Continued)

Wiring

1.Local electrical wiring codes differ from area to area. Source wiring, plug and protector must be rated for at least the amperage and voltage indicated on motor nameplate, and meet all electrical codes for this minimum.

2.Use a slow blow fuse or a circuit breaker.

Overheating, short circuiting and fire damage will result from inadequate wiring, etc.

NOTE: 120 volt, 15 amp units can be operated on a 120 volt circuit under the following conditions:

a.No other electrical appliances or lights are connected to the same branch circuit.

b.Voltage supply is normal.

c.Circuit is equipped with a 15 amp circuit breaker or a 15 amp slow blow fuse.

3.If these conditions cannot be met or if nuisance tripping of current protection device occurs, it may be necessary to operate compressor from a 120 volt, 20 amp circuit.

Operation

Moisture in compressed air

Moisture in compressed air will form into droplets as it comes from an air compressor pump. When humidity is high or when a compressor is in continuous use for an extended period of time, this moisture will collect in the tank. When using a paint spray or sandblast gun, this water will be carried from the tank through the hose, and out of the gun as droplets mixed with the spray material.

IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying other than water based paints. If sandblasting, it will cause the sand to cake and clog the gun, rendering it ineffective. A filter in the air line (MP3105), located as near to the gun as possible, will help eliminate this moisture.

This compressor can be used for general inflation as well as intermittent duty air tool usage. For inflation purposes, this compressor utilizes a new technology called Rapid Inflation Technology (RIT).

IMPORTANT: Make sure the Wheel Lock/Foot Brake is engaged before operating the unit (See Figure 11).

ASME Safety Valve

Do not remove or attempt to adjust the safety valve!

This valve should be checked under pressure occasionally by pulling the ring by hand (See Figure 13). If air leaks after ring has been released, or valve is stuck and cannot be actuated by ring, it MUST be replaced.

Click-To-Set Regulator Knob

υThis knob controls air pressure to an air operated tool, or paint spray gun.

υTurning knob clockwise increases air pressure at outlet.

υTurning counterclockwise will lower air pressure at outlet.

υFully counterclockwise will shut off flow of air completely.

This regulator knob is designed to rotate approximately 270 degrees for all feature settings. If the knob is rotated past minimum operation setting (counterclockwise), the knob will no longer “click” as designed to indicate that the regulator has been placed in a specific setting. The outlet pressure will read zero (0 psi) once the knob is at the minimum operation setting. Continuous turning of the regulator knob past minimum operation setting (counterclockwise) could result in the regulator knob coming loose and detaching.

If outlet pressure gauge is at zero (0) psi, DO NOT turn knob counterclockwise.

If regulator knob is turned and a “click”

is no longer heard, DO NOT turn knob counter clockwise.

Reassembly

If you do turn the regulator knob too far past minimum operation setting ( counterclockwise) and the knob does come off, use these steps to reassemble the regulator:

1.Align the spring into central position.

2.Locate retaining latch on inside of regulator knob.

3.Align retaining latch to the aluminum threads of the regulator body.

4.Attach at an angle, catching the retaining latch under the beginning of the aluminum threads.

5.Apply pressure to align knob to regulator body.

6.Turn clockwise until the knob clicks.

For further assistance or questions, please call 1-800-543-6400.

Outlet (Tool) Pressure Gauge

1.This gauge shows at-a-glance, air pressure at outlet. Air pressure is measured in pounds per square inch (psi).

2.Be sure this gauge reads ZERO before changing air tools or disconnecting hose from outlet.

Tank Pressure Gauge

Gauge shows pressure in tank indicating compressor is building pressure properly.

Operating Instructions and Parts Manual

Operation (Continued)

Rapid Inflation Technology™ (RIT)

When the compressor is used in the RIT mode, the air being produced from the compressor pump will go directly to the recoil hose which is attached to the bottom of the compressor (See Figure 15). This will eliminate waiting for the compressor tank to fill up, allowing for significantly faster inflation.

Instant air hose will get hot while the compressor is on and during the inflation process.

Drain water from tank prior to inflation.

To Use Compressor For Inflation:

1.Connect recoil hose to open port located on the bottom of compressor (See Figures 10 and 15). The coil hose and blow gun must remain attached so that the unit operates properly.

2.Attach blow gun to the other end of the recoil hose. The blow gun should ALWAYS be connected to the recoil hose.

3.To inflate balls, rafts, etc. attach inflation needle or nozzle to the end of blow gun.

4.To inflate tires, attach tire inflation valve to the end of blow gun.

5.Attach the appropriate inflation device to object needing inflation.

6.Turn on compressor by firmly pressing down the red power foot switch and inflate by squeezing the trigger.

Use caution to avoid over inflation.

7.When inflation is complete, blow gun can be attached to the clip that is molded on the side of the top shroud for convenient storage.

To Use Compressor For Air Tool Usage:

1.Connect 1/4 inch industrial plug to separate hose (plug and hose not included).

2.Connect separate hose to the coupler located below pressure regulator by pulling the sleeve on coupler all of the way back, then push hose into coupler and release sleeve (See Figure 17).

3.Close regulator (turn knob fully counterclockwise to the left). Do not over tighten.

If outlet pressure gauge is at zero (0) psi, DO NOT turn knob counterclockwise.

If regulator knob is turned and a “click” is no longer heard, DO NOT turn knob counterclockwise.

4.Turn compressor on by firmly pressing down the red power foot switch and allow it to fill tank until it reaches automatic shut off pressure.

5.Attach air tool, paint gun, nailer, etc. to end of air hose.

6.Adjust regulator for desired application. Regulator has preset “click-to-set” feature which should closely match application pictures on outlet pressure gauge.

7.Use compressor for desired application.

End of Operation/Storage

1.Turn compressor off at foot pedal on/off switch.

2.Unplug power cord from wall outlet and attach to clip that is molded on the side of the top shroud.

3.Drain tank of condensation as outlined in the Drain Tank section below.

WL6700 Series

Operation (Continued)

4.Wearing safety glasses, drain tank of any remaining air pressure by pulling the ring on the safety valve. Use other hand to deflect any fast moving air that may be directed towards your face.

5.Store compressor in a cool, dry place.

Maintenance

Disconnect power source then release all pressure from the system before attempting to install, service, relocate or

perform any maintenance. Service should be performed by an authorized service representative.

The compressor should be checked often for any visible problems and the

following maintenance procedures should be performed each time the compressor is used.

ASME Safety Valve

Do not remove or attempt to adjust the safety valve!

Check the safety valve by performing the following steps:

1.Plug the compressor in and run until shut off pressure is reached (see Operating Procedure).

2.Wearing safety glasses, pull the ring on the safety valve to release pressure from compressor tank. Use your other hand to deflect fast-moving air from being directed toward your face.

3.The safety valve should automatically close at approximately 40-50 psi. If the safety valve does not allow air to be released when you pull on the ring, or if it does not close automatically, it MUST be replaced.

Drain Tank

1.Turn compressor off at foot pedal switch.

2.Check air pressure in tank. To properly drain tank of condensation, tank pressure should be between 20-60 psi. Drain system will not work if there is no pressure in the tank. If tank pressure is above 60 psi, decrease pressure in tank by pulling the ring on the safety valve. Burst of air will be audible.

3.Slowly turn easy drain knob, located below the tank gauge, to the left (counterclockwise) until fluid begins to fill drain cup. Watch draining to make sure drain cup does not overflow. If there is a lot of fluid in the tank, you may need to close drain knob by turning fully to the right (clockwise) then remove the drain cup to dispose of fluid.

4.When fluid stops draining, close drain knob by turning all the way to the right (clockwise).

5.Lift cup up and pull out to dispose of drained fluid. Reinsert cup, making sure to secure in place.
