SAFETY GUIDELINES

WARNING!

Pull the pressure safety valve ring every day in order to ensure that the valve is functioning properly.

The compressor must be located in a well-ventilated area for cooling, and must be a minimum of 12" 
(31 cm) away from the nearest wall.

Protect the air hose and the power cord from damage and puncture. Inspect them for weak or worn spots 
every week, and replace them if necessary.

Always wear hearing protection when using an air compressor. Failure to do so may result in hearing loss. 

Do not carry the compressor while it is running.

Do not operate the compressor if it is not in a stable position.

Do not operate the compressor on a rooftop or an elevated position that could allow the unit to fall or be 
tipped over. 

Always replace a damaged gauge before operating the unit again.

RATING

7. 

RISK OF BURNS.

The pump and the manifold generate high temperatures.  In order to 

avoid burns or other injuries, do not touch the pump, the manifold or the transfer tube 

while the compressor is running. Allow the parts to cool down before handling or 

servicing. Keep children away from the compressor at all the times. 

 

8. 

 Be certain to read all labels when you are spraying paints or 

toxic materials,  and follow all safety instructions. Use a respirator mask if there is a 

chance of inhaling anything you are spraying. Also, NEVER directly inhale the air 

produced by a compressor.   

9. 

 

 Wear ANSI Z87.1 approved safety goggles when using an air 

RISK OF BREATHING.

RISK OF EYE INJURY.

compressor.  Do not point any nozzle or sprayer toward a person or any part of the 

body. Serious injury may occur if the spray penetrates the skin.

 

 

Extension cords

As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using 

extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power 

and possible product damage. Refer to the table here to determine the required minimum wire size.

Recommended Minimum Wire Gauge for Extension Cords* (120 V)   

* Based on limiting the line voltage drop to  five volts at 150% of the rated amperes. 

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge  

cord can carry a higher current than a 16 gauge cord. When using more than one extension cord to make

up the total length, be sure each cord contains at least the minimum wire size required.  

 

Guidelines for using extension cords

 

 

 

 

If you are using an extension cord outdoors, be sure it is mar ked with the suffix  "W-A "("W " in 

Canada) to indicate it is acceptable for outdoor use.

Ensure your extension cord is properly wired and in good electrical condition. Alway replace a 

damaged extension cord or have it repaired by a qualified technician before using it.

Protect your extension cords from sharp objects, excess heat, and damp or  wet  areas.
