The portable air compressor is equipped with a cord having a grounding wire with an appro- priate grounding plug.
1.The cord set and plug (M) with this unit contains a grounding pin (L). This plug MUST be used with a grounded outlet (K).
IMPORTANT: The outlet being used must be installed and grounded in accordance with all local codes and ordinances.
2.Ensure the outlet being used has the same configuration as the grounded plug. DO NOT USE AN ADAPTER.
3.Inspect the plug and cord before each use. Do not use if there are signs of damage.
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 quali- fied electrician.
danger: 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 3‑slot receptacle that will accept the plug on the product
•in good condition
•no longer than 50 feet (15.2 m)
•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.)
NOTICE: Risk of Property Damage. The use of an undersized extension cord will cause volt- age to drop resulting in power loss to the motor and overheating. Instead of using an exten- sion 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 Voltage and Minimum Branch Circuit Requirements under Pump/Motor Specifications.
CAUTION: Risk of Overheating. Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.

Cut-In Pressure: While the motor is off, air tank pressure drops when accessory is used. When the tank pressure drops to a certain low level the motor will restart automatically. The low pressure at which the motor automatically restarts is called cut-inpressure.
Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called cut-outpressure.
Branch Circuit: The circuit carrying electricity from electrical panel to outlet.
Duty Cycle: This air compressor pump is capable of running continuously. However, to prolong the life of your air compressor, it is recommended that a 50%-75% average duty cycle be maintained; that is, the air compressor pump should not run more than 30-45 minutes in any given hour.
