If you find anything wrong, do not operate the tool until the parts have been replaced or the fault has been rectified. Failure to do so could result in serious personal injury. Connecting to the power supply The GMC Bench Grinders covered in this manual are designed to operate from a standard household supply of 230-240V AC. Prior to plugging in the tool, check the rating label on the rear of the grinder and ensure that it states the tool’s operating voltage is 240V. All the grinders are of Class 1 Category (earthed) and are fitted with a 3-core cable and plug. Should the cable or plug be damaged, the product should be serviced by an authourised Service Centre to avoid a hazard. 6 Know your product Before using the bench grinder, familiarise yourself with all the operating features and safety requirements. The GMC Bench Grinders are designed for light to moderate duty applications in a home environment. They are not intended for use by trade persons. They are ideal for sharpening tools such as drill bits and chisels. The larger tools can be applied to heavier grinding applications on steel sections. These grinders are not a continuously rated tool and should not be operated for more than 10 minutes continuously at a time under load. If the tool is used for this period of time under load the grinder should then be turned off for a minimum of 30 minutes. All the bench grinders can be fitted with a wire wheel provided that the wheel is rated for use at 3000RPM or higher. Guard exhaust All grinders are fitted with a rear guard exhaust. This exhaust is provided to assist in the prevention of grinding dust build up within the guard assembly. Grinding sparks and dust will project from these exhausts from the rear. Ensure the following: • Combustable items are not directly behind the grinder. • During use ensure other persons are not directly behind the grinder. • Never attempt to connect any form of dust extraction machine to the grinder. 1. Eye shield 2. Grinding wheel 3. Outer guard 4. Rubber coated mounting position 5. Base 6. On/Off switch 7. Adjustable tool rest 8. Wheel guard 9. Eye shield bracket 10. Water bath 11.

The grinder should run at close to full speed. If you are applying too much pressure the grinder will start to slow down. Under these conditions, remove the part being ground and allow the grinder to return to full speed. Re-apply the part to the grinder, but with a little less force. All of the grinding wheels are supplied with grinding wheels designed for metal use only. The grinding of Copper, Brass, Aluminium, Wood or other similar materials will “clog” the grinding wheel. Warning. Never attempt to grind Magnesium. Fitting and adjusting the eye shields and brackets. Important. Prior to fitting the eye shield brackets, ensure the grinder is turned off and the power plug is removed from the socket. Note. Always check to ensure the eye shields (1) are correctly fitted and the eye shield brackets (9) are correctly adjusted each time the grinder is used. Eye shields and brackets must be fitted over each grinding wheel on all the bench grinders in the range, except the sharpening wheel (11) on Model NTS2000A. 1. Remove the top screw of the wheel guard (8). 2. Fit the eye shield bracket (9). 3. Fit a flat steel washer on to the wheel guard screw and then pass the screw through the eye shield bracket, guard and then the eye shield bracket again. Fit another flat washer, followed by the spring washer and then the nut. Tighten the nut so the bracket can slide. 4. Fit the eye shield (1) to the top of the bracket. Secure the eye shield by passing the 45mm x 5mm screw through both the bracket (9) and eye shield (1). Tighten the screw to the point where the eye shield will move with firm resistance. 5. Slide the eye bracket inward or outwards so the edge of the bracket is less than 6mm from the surface of the wheel as shown, but not touching the wheel. 6. Rotate the wheel by hand one full revolution to ensure the wheel can rotate without contacting the bracket. Firmly tighten the screw retaining the bracket. Important. Ensure that the washers as shown in the photograph are correctly positioned. Fitting the tool rests. The tool rests (7) are required for each high speed grinding wheel to assist in the grinding operation. (They are not required on the sharpening wheel on the NTS2000A). Caution. Never use a Bench Grinder on which the tool rest has not been fitted or where the tool rest has not been correctly adjusted. The tool rests supplied are left or right handed. Important. Prior to fitting the tool rests, ensure the grinder is turned off and the power plug is removed from the socket. 1. Remove the lower screw on the wheel guard (8). 2. Hold the tool rest (7) in the correct position against the outer surface of the inner wheel guard. Fit the screw throu...
