AllTrade Air Plus 11 Gal Air Compressor 540010 User Manual

							TOO MUCH AIR PRESSURE CAUSES A HAZARDOUS RISK OF BURSTING. CHECK THE MANUFACTURERS MAXIMUM PRESSURE
RATING FOR AIR TOOLS AND ACCESSORIES. THE REGULATOR OUTLET PRESSURE MUST NEVER EXCEED THE MAXIMUM PRES-
SURE RATING.
7.Before connecting the compressor to the grounded outlet, check oil level, check for broken components and accessories, and
check for damage to the hose.
8.Plug power cord directly into a properly grounded power source of the correct voltage (see Grounding Instructions on page 7 of
this instruction manual).
9.Turn the compressor on by moving the switch to the AUTO/ON position and allow the tank pressure to build. Once the air pressure
reaches the maximum preset pressure (“cut-out” pressure) it will automatically shut off.
10.Slowly turn the pressure regulator knob clockwise to open airflow from air outlet port until desired output pressure is reached.
NOTE: The air compressor will automatically restart once the pressure in the air tank drops below the minimum preset pressure
(“cut-in” pressure).
SHUTDOWN:
NOTE:NEVER stop the air compressor by unplugging it from the power outlet as this may result in damage to the compressor.
1.Turn the switch to the OFF position
2.Disconnect the power cord from the power outlet.
3.Turn the pressure regulator knob fully counterclockwise to close airflow from air outlet port. Check the outlet pressure gauge to
ensure that it reads 0 PSI.
4.Remove the air hose and any air accessories.
5.Drain moisture from the air tank by slowly opening the air tank drain valve by turning clockwise. Tilt tank to remove all moisture.
Once all the moisture has drained out, close the fitting securely.
6.Allow the compressor to cool down.
7.Wipe the air compressor clean and store it in a clean, dry, and non-freezing location.
MAINTENANCE
DISCONNECT AIR COMPRESSOR FROM POWER SOURCE AND BLEED OFF ALL AIR PRESSURE BEFORE ATTEMPTING ANY MAINTE-
NANCE OR REPAIR.
When performing any maintenance or service:
1.The air compressor must be turned off.
2.Disconnect compressor from the power source.
3.Open tank drain to bleed off all air pressure before attempting any maintenance or repair.
4.Allow compressor to fully cool before attempting any maintenance or repair.
Check the air compressor frequently for any visible problems and follow maintenance procedures each time the compressor is used.
All air compressors contain maintenance parts that require periodic replacement. These used parts, including air filters and used lubri-
cating oil, may contain regulated substances that must be disposed of in accordance with local, state, and federal laws and regulations.
1.Turn compressor off and release pressure from the system. Drain moisture from the air tank by slowly opening the air tank drain
valve by turning clockwise. Tilt tank to remove all moisture. Once all the moisture has drained out, close the fitting securely.
2.Wipe the compressor clean.
Maintenance Checklist:
Daily:
Check oil level.
Drain accumulated liquid from tank.

WARNING
WARNING
NOTICE  
						

							Check for oil leaks.
Check for unusual noise and/or vibrations
Check that all fasteners are secure.
Check for air leaks+.
Wipe compressor clean.
Weekly:
Inspect and clean air filter.
Clean breather holes on oil fill plug.
Monthly:
Check for air leaks.
Check safety relief valve.
Six months or 200 operating hours*:
Change compressor oil. Use only SAE 30 weight non-detergent air compressor oil.
Replace oil more frequently when used in dusty operating environments.
* The pump oil must be changed after the first 20 hours of operation.Thereafter, change oil every 200 hours of operation or every six
months, whichever comes first. In harsh operating conditions, maintenance must be performed more frequently.
+ Apply a solution of soapy water around joints. Look for air bubbles around joints when compressor reaches the pressure cut-out limit
and the pump turns off.
Oil change:
Used lubricating oil, may contain regulated substances that must be disposed of in accordance with local, state, and federal laws and
regulations.
1.The air compressor must be turned OFF.
2.Allow compressor to fully cool before attempting any maintenance or repair.
3.Place a suitable oil drain pan below oil drain plug.
4.Remove oil fill plug to allow air to enter crankcase.
5.Remove oil drain plug.
4.Allow oil to drain completely. Tilt air compressor towards the oil drain to assist draining.
5.Clean and replace oil drain plug.
6.Refill crankcase with SAE 30 weight non-detergent air compressor oil until the oil level reaches the top of the red circle in the oil
level sight glass. Be careful not to overfill.
7.Reinstall the oil fill plug.
Checking Safety Relief Valve:
SAFETY VALVE MUST BE REPLACED IF IT CANNOT BE ACTUATED OR IT LEAKS AIR AFTER THE RING IS RELEASED.
1.The air compressor must be turned OFF.
2.Disconnect compressor from the power source.
3.Open tank drain to bleed off all air pressure before attempting any maintenance or repair.
4.Allow compressor to fully cool before attempting any maintenance or repair.
5.Grasp the wire ring on the safety valve.
6.Pull and release the ring a few times to ensure that the plunger moves in and out. Replace the safety valve if plunger does not
move or is difficult to move.
Checking Air Filter Element:
1.The air compressor must be turned OFF.
2.Disconnect compressor from the power source.
3.Open tank drain to bleed off all air pressure before attempting any maintenance or repair.
4.Allow compressor to fully cool before attempting any maintenance or repair.
5.Unscrew the filter, which is accessible from the rear of the air compressor, from the pump head by turning counter clockwise.
6.Remove the face of the filter body to access the filter element.

WARNING  
						

							7.Clean filter element with warm soapy water. Rinse the filter and air dry before reinstalling.  Replace filter element if it cannot be
cleaned sufficiently.
8.Reinsert filter element into filter body and reinstall filter faceplate.
9.Screw the filter body into pump head by turning clockwise until the filter is hand tight. DO NOT OVERTIGHTEN.
MOISTURE IN COMPRESSED AIR
Moisture is a normal by-product of compressing air. As the moisture builds during compressor use, it can be carried though the air
hose. When using a paint spray gun or sandblasting gun, the use of a special filter to remove moisture from the air line is highly rec-
ommended. Moisture in the compressed air will cause water spots in paint jobs and cause blasting media to clog the sandblasting gun.

tion:

compressor. If the electrical contacts are welded
together, replace the pressure switch.
Limit the air pressure to the capacity of the air com-
