  Electrical Connections 

 

Electrical connections must 

be made by a qualified electrician in 
compliance with all relevant codes. 

 

The powerfeeder is equipped with a 110 volt motor 
and a plug designed for use on a circuit with a 

grounded outlet 

that looks like the one pictured in 

A

, Figure 11. 

6.7.1

  Grounding instructions 

1. All Grounded, Cord-connected Tools: 

In the event of a malfunction or breakdown, 
grounding provides a path of least resistance for 
electric current to reduce the risk of electric shock. 
This tool is equipped with an electric cord having 
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 connection of the equipment-grounding 
conductor can result in a risk of electric shock. The 
conductor with insulation having an outer surface 
that is green with or without yellow stripes is the 
equipment-grounding conductor. 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 pe

r

sonnel if the 

grounding instructions are not completely 
understood, or if in doubt as to whether the 
tool is properly grounded. Failure to comply 
may cause serious or fatal injury.

 

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 damaged or worn cord 
immediately. 

2. Grounded, cord-connected tools intended for 
use on a supply circuit having a nominal rating less 
than 150
 volts: 

This tool is intended for use on a circuit that has an 
outlet that looks like the one illustrated in 

A, 

Figure 

11. An adapter, shown in 

B

 and 

C

, may be used to 

connect this plug to a 2-pole receptacle as shown 
in 

C

 if a properly grounded outlet is not available. 

The temporary adapter should be used only until a 

properly grounded outlet can be installed by a 
qualified electrician. 

This adapter is not permitted 

in Canada.

 The green-colored rigid ear, lug, and 

the like, extending from the adapter must be 
connected to a permanent ground such as a 
properly grounded outlet box.

6.7.2

  Extension Cords 

The use of extension cords is discouraged; try to 
position equipment within reach of the power 
source. If an extension cord becomes necessary, 
make sure the cord rating is suitable for the 
amperage listed on the machine’s motor plate. An 
undersized cord will cause a drop in line voltage 
resulting in loss of power and overheating. 

Use Table 1 as a general guide in choosing the 
correct size cord. If in doubt, use the next heavier 
gauge. The smaller the gauge number, the heavier 
the cord.
