CX-3E1                                                                                                         SAFETY

WARNING

In order to prevent electrical shock and injury, the following electrical safety precautions and symbols 

should be followed at all times!

In case of a malfunction or breakdown, grounding provides a path of least resistance for electrical 

current to reduce the risk of electric shock. This tool is equipped with an electric cord which has an 

equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching 

outlet that is properly installed and grounded in accordance with all local codes and ordinances.

•   DO NOT modify the plug provided - if it will not fit the outlet, have the proper outlet 

  installed by a qualified electrician.

•   Improper connections of the equipment-grounding conductor can result in a risk of electric  

  shock. The equipment-grounding conductor is the insulated conductor that has an outer  

  surface that is green, with or without yellow stripes. If repair or replacement of the electric  

  cord or plug is necessary, DO NOT connect the equipment-grounding conductor to a live  

  terminal.

•   Check with a qualified electrician or service personnel if the grounding instructions are not  

  completely understood, or if in doubt as to whether the tool is properly grounded.

•   Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles  

  that accept the tool’s plug.

•   Repair or replace a damaged or worn cord immediately.

For maintenance care and operation of the electric motor, refer to your electric motor instruction book-

let furnished with the electric motor. Protect the electric motor from dust as much as possible and keep 

ventilating openings clean. Before plugging in the machine, make sure that the outlet voltage is within 

the voltage marked on the machines's data plate.

DO NOT spray water on the electric motor. DO NOT touch the plug with wet hands. To reduce 

the risk of electrocution, keep all connections dry and off the ground.
