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, tank and other 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 tank protects parts from rust and corrosion***

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
