Husky 80-Gallon Stationary Air Compressor C801H

DANGER: Do not tamper with the safety valve. Items loosened from this device could fly up and hit you. Failure to heed this warning could result in death or serious personal injury.

WARNING: If air leaks after releasing the safety valve ring or if the valve is stuck, do not use the air compressor until the safety valve has been replaced. Using the air compressor in this condition could result in serious personal injury.

Set the Auto/Off switch to “On”.

Did the compressor automatically shut off when the pressure reached the preset maximum?

Set the Auto/Off switch to “Off”.

Did you pull the ring on the safety valve for 20 seconds to release the air?

Did air stop escaping at about 20 psi after releasing the safety valve ring?

If air continues to escape after releasing the safety valve ring, discontinue use and seek service before using the air compressor again.

Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank

Place a straightedge against the outside of the flywheel and the motor drive pulley

Measure the distance between the edge of the belt and the straightedge at points A1 and A2 in figure. The difference between measurements should be no more than 1/16” (1.6 mm)

If the difference is greater than 1/16” (1.6 mm) loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measurements are within 1/16” (1.6 mm) of each other

Tighten the motor drive pulley set screw

Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If they are not, loosen the setscrew of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2

Retighten the motor drive pulley setscrew. Torque to 145–165 in lbs (16.4–20.3 Nm)

NOTICE: All compressed air systems generate condensate that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations.

NOTICE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.

Set the Auto/Off switch to “Off”.

Slowly bleed the air from the air tank and air distribution system until tank pressure is approximately 20 psi.

Drain water from air tank by opening drain valve on bottom of tank.

After the water has been drained, close the drain valve. The air compressor can now be stored.

WARNING: Serious injury or damage may occur if parts of the body or loose items get caught in moving parts. Never operate the outfit with the belt guard removed. The belt guard should be removed only when the air compressor power is disconnected.

Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

Loosen the motor mounting screws and slide the motor toward the air compressor.

Remove the belt and replace with a new one.

See the Adjust Belt Tension before tightening motor mounting screws.
