Jet IBDG-248, Operating Instructions And Parts Manual

 12 

It is recommended that the sander be connected to 
a minimum 15-amp circuit with circuit breaker or 
fuse. If using fuses, they should be time-delay fuses 
marked “D”. 

Local codes take precedence over 

recommendations.

  GROUNDING INSTRUCTIONS 

1. All Grounded, Cord-connected Tools: 

This tool must be grounded. 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 

7-1. An adapter, shown in 

B

 and 

C

, may be used to 

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

B

 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.  

Note

: In Canada, the use of a temporary adaptor is 

not permitted by the Canadian Electrical Code, 
C22.1.  

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.

3. Grounded, cord-connected tools intended for use 
on a supply circuit having a nominal rating between 

150 - 250 volts

, inclusive: 

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

D,

 Figure 

7-1. A grounding plug may be installed, that looks 
like the plug illustrated in 

D

; or the grinder may be  

“hard-wired” to a panel, provided there is a 
disconnect for the operator.  

Make sure the tool is connected to an outlet having 
the same configuration as the plug. No adapter is 
available or should be used with this tool. If the tool 
must be reconnected for use on a different type of 
electric circuit, the reconnection should be made by 
qualified service personnel; and after reconnection, 
the tool should comply with all local codes and 
ordinances. 

4. Permanently connected tools: 

This tool should be connected to a grounded metal 
permanent wiring system; or to a system having an 
equipment-grounding conductor. 

5. Polarized plugs

 – To reduce the risk of electric 

shock, this equipment has a polarized plug (one 
blade is wider than the other). This plug will fit in a 
polarized outlet only one way. If the plug does not fit 
fully in the outlet, reverse the plug. If it still does not 
fit, contact a qualified electrician to install the proper 
outlet. Do not change the plug in any way. 

7.2

  Extension cords 

The use of extension cords is discouraged. Try to 
position equipment near the power source. If an 
extension cord becomes necessary, use only three-
wire extension cords that have three-prong 
grounding type plugs and three-prong receptacles 
that accept the tool's plug. Replace or repair 
damaged or worn cord immediately. 

Make sure your extension cord is in good condition, 
and is heavy enough to carry the current your 
product will draw. An undersized cord will cause a 
drop in line voltage resulting in loss of power and 
overheating.
