Electrical Safety
WARNING:
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are not sure that the outlet is
properly grounded. Do not modify the plug provided with the tool. Never
remove the grounding prong from the plug. Do not use the tool if the cord or
plug is damaged. If damaged, have it repaired by a qualified electrician
before use. If the plug will not fit the outlet, have a proper outlet installed by
a qualified electrician.
Some of our machines are equipped with 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 a polarized outlet. Do not change the plug in any
way.
Double insulation eliminates the need for the three wire grounded power supply system mentioned above.
Do not expose your tool to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
The plug must be connected to a properly grounded outlet (see Figure 1). If the tool should electrically
malfunction or break down, grounding provides a low-resistance path to carry electricity away from you, reducing
the risk of electric shock.
Figure 1: Grounded Plug and Outlet
The grounding prong on the plug is connected through the green wire inside the cord to the grounding system in
the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must
never be attached to an electrically “live” terminal.
Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes
and ordinances. The plug and outlet should look like those in Figure 1.
Figure 2 illustrates a temporary adapter available for connecting grounded plugs (Figure 1) to two-prong outlets.
The green rigid ear or lug extending from the adapter must be connected to a permanent ground such as a
properly grounded outlet box or receptacle. Simply remove the center screw from the outlet, insert the adapter
and reattach the screw through the green grounding ear to the outlet. If in doubt of proper grounding, call a
qualified electrician. A temporary adapter should only be used until a qualified electrician can install a properly
grounded outlet. The Canadian Electrical Code prohibits the use of temporary adapters.
