Grounding Instructions

Risk of Electrical Shock. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.

The portable air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug (see illustration).

1.The cord set and plug with this unit contains a grounding pin. This plug MUST be used with a grounded outlet.

IMPORTANT: The outlet being used must be installed and grounded in accordance with all local codes and ordinances.

2.Make sure the outlet being used has the same configuration as the grounded plug. DO NOT USE AN

ADAPTER. See illustration.

3. Inspect the plug and cord before each

use. Do not use if there are signs of damage.

Grounded Outlets

4.If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualified electrician.

Risk of Electrical Shock. IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.

Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should be installed by a qualified electrician.

Repairs to the cord set or plug MUST be made by a qualified electrician.

Extension Cords

If an extension cord must be used, be sure it is:

a 3-wire extension cord that has a 3-blade grounding plug, and a 3slot receptacle that will accept the plug on the product

in good condition

no longer than 50 feet

12 gauge (AWG) or larger. (Wire size increases as gauge number, decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR 16 AWG.)

Risk of Property Damage. The use of an undersized extension cord will cause voltage to drop resulting in power loss to the motor and overheating. Instead of using an extension cord, increase the working reach of the air hose by attaching another length of hose to its end. Attach additional lengths of hose as needed.

Voltage and Circuit Protection

Refer to the Specification chart for the voltage and minimum branch circuit requirements.

Risk of Operation. Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.

1.Voltage supply to circuit must comply with the National Electrical Code.

2.Circuit is not used to supply any other electrical needs.

3.Extension cords comply with specifications.
