least 0.3 m away from the wall or other obstructions that
would interfere with the flow of air. The compressor head
and shroud are designed to allow for proper cooling. If
humidity is high, an air filter can be installed on the air
outlet adapter to remove excessive moisture. Place the air
compressor on a level surface so that it rests securely on
the rubber feet. Follow the instructions packaged with the
air filter for proper installation.
LUBRICATION
This air compressor is equipped with an Oil-Less pump
designed for durability and no maintenance.
Please see the chart below for MINIMUM extension cord gauge requirement:

Piping
This air compressor is not designed for use with piping.
Never use compressed air with any kind of piping
connected.
DANGER:
Improper grounding can result in electrical shock. Do not
modify the plug that has been provided. If it does not fit
the available outlet, the correct outlet should be installed
by a qualified electrician.

Power supply
Operate the compressor at voltage specified on the
nameplate. If using the compressor at a higher voltage
than the rated, it will result in abnormally fast motor speed
and may damage the unit and burn out the motor. Also if
using the compressor at a low voltage, it will result in
abnormally slow motor speed and may overheat and shut
off the motor.
Extension Cords
To avoid voltage drop, power loss, and overheating of the
motor, use extra air hose instead of an extension cord.
Low voltage can cause damage to the motor.
If an extension cord must be used;
• Make sure the extension cord is in good condition.

the air regulator or shut-off valve is closed. Ensure
compressor is disconnected from the main supply.
2. Attach hose and accessories. Too much air pressure
causes a hazardous risk of bursting. Check the
manufacture's maximum pressure rating for air tools
and accessories. The regulator outlet pressure must
never exceed the maximum pressure rating.
3. Connect a plug to the outlet.
4. Start the compressor with turning the switch to ON "|".
Select a operation mode by mode select switch. Close
the drain valve. Motor will stop when tank pressure
reaches "cut-off" pressure.
5. Open the regulator by turning it clockwise. Adjust the
regulator to the correct pressure setting. Your
compressor is ready for use.
6. Always operate the air compressor in well-ventilated
areas; free of gasoline or solvent vapors. Do not
operate the compressor near the spray areas.
Operating mode
This compressor has a 4 type of operation modes. You
