AIR COMPRESSOR

MAINTeNANCe

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. daily draining is recommended to not damage the air

compressor motor, dryer, tank and components.

1.

Place the air compressor above a container capable of holding

water. A pan with a dry towel would be advised.

Locate the drain valve at the bottom of the air tank.

2.

Without compressed air in the air tank, slowly turn the drain valve

knob to the forward (open) or straight down position.

The water in the air tank will drain out. 

3.

After all of the accumulated water has drained out, turn the drain

valve knob to the closed or left position in order to avoid leakage.

draining the air dryer

1.

At the bottom of the air drying column is a drain hole with a drain

tube attached.

Attach the other end of the drain tube to a container capable of

holding water. This tube will let the water from the air dryer drain.

2.

Remove waste container and empty.

changing the air filter

The air filters are 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 of the air filter and remove the old air filter element.

2.

Replace with a new air filter element and close the lid.

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.

air drying column - desiccant

After 4000 hours of use the Activated Alumina desiccant needs to

be replaced.
unscrew the air drying column bottom cap.
Remove the old desiccant (disguard) and add new desiccant.

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

dust and moisture.

6.

do not stack or store any items on top of or around the air

compressor. damage could occur.
