7) EXTENSION CABLE SELECTION

Note: Make sure the proper extension cord is used and is in good condition.
The use of any extension cord will cause loss of power. To keep this to a minimum and prevent overheating and motor burnout,
use the information below to deter-mine the minimum wire size extension cord.
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug. When using
a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the
tool will draw. An undersized extension cord will cause a drop-in line voltage, resulting in a loss of power and causing the motor
to overheat. Use the information provided below to determine the minimum wire size required in an extension cord. Only round
jacketed cords listed by Underwriter's Laboratories approval should be used.
For 110v supply: 3.5metres of 3 core x 1.5mm²
For230v supply: 26metres of 3 core x 1.5mm²
When work with the tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters WA on
the cord's jacket.
Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.
Power Connections
A separate electrical circuit should be used for your tools. This circuit should not be less #12 wire and should be protected with
a 20 Amp fuse. Have a certified electrician replace or repair a worn cord immediately. Please connecting the motor as
nameplate mentioned, Running low voltage will damage the motor.
WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP
