draining the air tank
The frequency at which you should drain the air tank depends on
the environmental conditions and the amount of operating time
logged. The average draining frequency is every 2 to 3 days.
1. Place the air compressor above a container capable of holding
water.
2. With compressed air in the air tank, slowly turn the drain valve
knob counterclockwise. The water in the air tank will drain out.
3. After all of the accumulated water has drained out, turn the
drain valve knob clockwise until it is tight, in order to avoid
leakage.
changing the air filter
The air filter is designed to reduce noise and help prevent
particulates in the air from entering and damaging the air
compressor.
After being used for a period of time, the air filter will become
clogged. This will reduce the air intake capabilities of the air
compressor, reducing performance. Therefore, the air filter must
be replaced regularly.
1. Open the lid on the air filter, then remove the old filter.
2. Replace it with a new filter, then close the lid.
oil maintenance
Checking the Air Compressor Oil
1. Place the Air Compressor on a level surface.
2. The oil level should be at the red dot on the Oil Sight Glass.
3. If oil level is low, add oil to the red dot on the Oil Sight Glass
changing the air compressor oil
Note: Change oil every 300 hours with air compressor oil.
1. Remove the Oil Sight Glass by turning counterclockwise.
note: Oil will begin to drain as Oil Sight Glass is loosened.
Place a funnel and oil pan in place
beFORe loosening Oil Sight Glass.
2. Once Oil Sight Glass is removed, tilt the air compressor
backwards to allow all of the oil to drain out of the crankcase.
3. Once oil is drained, replace Oil Sight Glass and securely
tighten in place with a wrench. do not overtighten the
Oil Sight Glass, as this could damage the rubber seal.
4. Place Air Compressor on level surface.remove breather Cap
5. Slowly pour the oil into the oil fill hole, until the oil level rises to
the center of the red dot on the Oil Sight Glass.
6. Install the Oil breather Cap into the oil fill hole.
Firmly hand tighten the Oil breather Cap by turning clockwise.
testing for Leaks
Make sure all connections are tight. do not overtighten.
A small leak in any hose or pipe connection will reduce the air
compressor's performance.
To test for small leaks, spray a small amount of soapy water on
the area suspected of leaking. If the soap bubbles, replace the
broken part.
cleaning
Clean items with a soft brush, or wipe with a moistened cloth
using a biodegradable solvent.
do not use flammable liquids such as gasoline or alcohol. Always
keep parts clean from dirt and dust for better performance.
adjusting the pressure Switch
The pressure switch is used to control the automatic stop-and-
start function of the air compressor, ensuring the correct pressure
of the compressed air in the air tank is maintained.
If the pressure of the compressed air in the air tank is found not to
be in the standard range set by the manufacturer, the pressure
switch must be adjusted to correctly set the activation valve. (The
pressure at which the air compressor will stop running is 8 bar,
and the pressure at which the air compressor will start running
again is 6 bar.)
Adjust the pressure switch as follows:
1. Open the casing to access the pressure switch.
2. Adjust the setting screw for the maximum pressure. Turning
3. Adjust the setting screw for pressure difference. Turning the
Gradual adjustments should make the activation pressures within
the range set by the manufacturer.
STORAGe
before storing for a prolonged period of time:
1. Turn off the power supply.
2. disconnect the power cord from the power supply.
3. Pull the relief valve and release all the pressure from the air
tank.
4. Clean the air compressor to remove all dirt and dust.
5. Cover the air compressor with a cover to protect the unit from
6. do not stack or store any items on top of or around the air

the setting screw clockwise makes the activation pressure
higher, so the pressure at which the air compressor stops
running will be higher.
setting screw clockwise makes for a larger pressure difference,
so the difference between the pressure at which the air
compressor starts and the pressure at which the air
compressor stops is larger.
