Be aware of possible damage to the drain lines that may result from the discovery of roots and obstacles.
To prevent electric shock and death from incorrect grounding wire connection. Check with
a qualied electrician if you are in doubt as to whether an outlet is properly grounded.
3-Prong
Plug and
Outlet
1. Tools marked with “Grounding Required” have a three wire cord and three
prong grounding plug. The plug must be connected to a properly grounded
outlet. If the tool should malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk electric
shock.
2. The grounding prong in the plug is connected through the green wire inside
the cord must be the only wire cinnected to the tool’s grounding system and
must NEVER be attached to an electrically “live” terminal.
Ground Fault Circuit Interrupter (GFCI)
Your machine is equipped with a GFCI, which protects against electric shock if a short circuit should occur.
Check that the receptacle is properly grounded and test the GFCI before each use.
1. Plug the GFCI power plug into a grounded receptacle.
2. Press the “TEST” button. The GFCI indicator light will go out and power to the machineshould cut off.
3. WARNING: If the light does not go out when the TEST button is depressed. Equipment should not be used
until proper repairs have been made by a qualied technician.
4. To restore power after testing, push the reset button. WARNING: If the machine doesn’t start, stops while
running or if you experience a mild shock, DO NOT use the machine. Have it repaired by a technician.
NOTE: The power cord is NOT GFCI protected from the GFCI unit to the 3-prong plug in the outlet.
Extension Cords
1. Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three
wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using
an inadequately sized wire causes a serious drop in voltage, resulting in a loss of power and possible tool
damage.
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge
cord can carry a higher currentthan a 16 gauge cord. See Table A
4. If the extension cord is being used for more than one tool, add the nameplate amperes and use the sum
to determine the required minimum cor size.
