Ensure that the handle is fully screwed in place and firm. Disc guard WARNING. Switch off the grinder and disconnect it from the power point. NOTE. Grinding operations normally require the angle grinder to be held with the grinding disc parallel to the plane of the workpiece whilst cutting operations normally require the angle grinder to be held with the cutting disc at right angles to the workpiece. Take the time to find the best combination of front handle and slimline handle positions to suit the task on hand. It can make a considerable difference to the levels of convenience and safety of operation. 1. Open the quick release guard lever (14). 2. Position the lug on the inside of the central guard ring in the vertical slot in the spindle cover and press the guard onto the spindle cover. 3. Twist the guard to the appropriate position for either grinding or cutting. 4. Lock the guard in position with the quick release guard lever. Operation This angle grinder can be used for grinding and cutting steel, stone or ceramic workpieces such as pipe, box section, rectangular, angle iron steel bar, house bricks and tiles. Do not attempt to grind wood or a soft metal such as lead. The material will quickly “fill” the disc and render it useless. Before starting the grinder first ensure that the disc, disc guard and tool are in good condition. Position the guard (4) as described in the disc guard section so that it will deflect hot sparks away from the operator. Switching on and off 1. Plug the power cord into the power point. 2. Start the tool by depressing the on/off trigger switch (1). Release the trigger to stop the tool. 3. If you press the lock on button (2) while the trigger switch is depressed, the switch is kept in the operating position. To release the lock on button, press and release the trigger switch. 4. Hold the grinder firmly while it is switched on and only apply gentle pressure to the workpiece. Little more than the weight of the tool should be applied to give the best and most efficient material removal. Forcing and excessive pressure can cause dangerous disc fracture or damage to the tool. Hold the grinder at approximately 15° to 30. to the work and move slowly. 8 5. Once the grinding or cutting is finished, pull in and release the on/off switch (1) to stop the grinder. WARNING. Avoid flying sparks and ensure they do not hit any inflammable materials, as they are very hot and could cause personal injury or a fire. 15. 30. WARNING. The disc continues to turn for a few seconds even though the switch is turned off. Keep your hands well away from the moving disc. Led overload protection system Overloading the tool means the tool is being leaned on excessively during use, slowing down the speed of the tool. As a result of the motor slowing down, the internal fan does not work to its full capacity. 1. The LED Overload protection system will alert you when it is overloading. 2. The grinder will warn you when you are approaching overload by flashing the Yellow light 3. If you continue to ignore the yellow light or do not see it, the red light will come on and the grinder will immediately come to a stop. 4. When this occurs, wait a brief moment then restart the grinder, however, take additional care not to press on the tool too much. Variable speed The variable speed feature of this grinder enhances the grinding performance and saves the disc from undue wear. 1. The variable speed dial (13) is used to program the speed of the disc. The speed should be adapted to the material being grinded. 2. Use your finger or thumb to turn the dial forwards to increase the speed and backwards to decrease it. 3. Position “1” denotes the lowest speed. Position “6” denotes the highest speed. NOTE. Using the correct speed for the job increases the life of the disc. Variable speed with soft start This grinder is fitted with soft start technology. This feature operates when you start the tool by slowly increasing the power to the selected speed. The soft start feature eliminates any “kick” when the grinder is switched on. In conventional grinders without soft start the switch is heated up instantly thus reducing the life expectancy. The soft start feature ensures a longer life for the tool. Replacing a disc CAUTION. Switch off the grinder and disconnect it from the power point. 1. Turn the angle grinder on to its back and press the spindle lock button (3) and rotate the spindle until it locks. 2. Insert the pins of the wrench (9) into the holes in the outer flange (10) and remove it and the old disc. NOTE. Do not remove the inner flange (12). 9 WARNING. Do not use a disc marked with a lower RPM than that of the Max no load speed shown on the rating plate. 3. Clean the flanges and check the new disc. 4. Holding the angle grinder with the spindle facing upwards, check that the inner flange is on the spindle and correctly located. The two machined flat sections must face the angle grinder and locate in the appropriate position on...
