Electrical Requirements

When connecting the bench grinder to the power source outlet, the outlet must be properly grounded to protect the operator from electrical shock.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electrical shock. This machine is equipped with an electric cord having an equipment-grounding conductor- outlet that is properly installed and grounded in accordance with all local codes and ordinances.

This grinder is equipped with a power cord. 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.

Plug power cord into a 110-120V properly grounded outlet protected by a 14-amp fuse or circuit breaker.

Do not touch the prongs of the power cord plug when plugging or unplugging to or from an outlet.

If improperly grounded, this power tool can cause serious injury from electrical shock, particularly when used in damp locations or near plumbing. If an electrical shock occurs, there is the potential of a secondary hazard such as your hands coming in contact involuntarily with the rotating grinder.

Electrical Connections

The BG6 and BG8 bench grinders are rated at 115V, 1Ph. These grinders are designed for use on a circuit with an outlet that looks the one shown in Fig. A. and have a grounding prong, also shown in Fig. A. A temporary adapter (Fig.

B)may be used to connect the plug to a two- prong receptacle (Fig. B) if a properly grounded outlet is not available. A temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored lug must be fastened to the cover plate screw.

Important: The adapter illustrated in Fig. B is for use only if you already have a properly grounded two-prong receptacle. Do not modify the plug provided-if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Before plugging into the power source, be sure that power switch is in the OFF position.

Extension Cords

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 core immediately.

USE PROPER EXTENSION CORD. Make sure your extension cord is good condition. When using an extension cord, be sure to use one 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. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage, The smaller the gage number, the heavier the cord.
