Power requirements

If faults or breakdowns happen. Ground connection offers a trajectory with minimum resistance for electric power. It reduces the risk of electric shock. This tool is built with a power cable with an earth conductor and ground connection. The plug shall be connected into a power outlet installed and grounded according to all local codes.

A power extension cord is not recommended to use with a compressor. Using an extension causes voltage drop, power loss in the motor and overheating. Instead of using an extension cord, increase the compressor’s action scope connecting a longer length of hose into the outlet. Connect additional hose lengths as required. Likewise, if needing to use a pneumatic tool outdoors in humid environment or even when raining, operate the compressor from the inside keeping it guarded from humidity. Operate the pneumatic tool connected to the compressor through additional lengths of hose without the risk of electric shock. In the event of connecting the compressor into a circuit protected with fuses, use delay action fuses type “D”.
