Wear a work apron. Pay attention that other persons are not put at risk from sparking. Remove flammable mate- rials in close vicinity. Sparking occurs when cutting metal.

Keep your workplace clean. Blends of materials are partic- ularly dangerous. Dust from light alloys can burn or explode. Products sold in GB only: Your product is fitted with a BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an author- ised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains sock- et elsewhere. Products sold in AUS and NZ only: Use a residual current de- vice (RCD) with a rated residual current of 30 mA or less.

provided. Mounting the Spark Guard/Workpiece Support (see figures A–D) Use the machine only with the spark guard 10. Sparks being expelled can injure your eyes or set objects in the vi- cinity on fire. – Mount the holder for the spark guard 9 with the two screws. – Screw the spark guard 10 to the holder of the spark guard

– Mount the workpiece support 11 as shown in the figure. Do not interchange the right and left workpiece sup- port 11. Otherwise, the clearance between workpiece support 11 and grinding wheel will be too large. When the clearance is larger, you are not sufficiently protected against sparking. The workpiece can be drawn in by the ro- tational motion of the grinding wheel and lead to injuries. Regularly check the clearance between the workpiece support 11 as well as the holder of the spark guard 9 to the grinding wheel, and readjust as required. The clear- ance to the grinding wheel may not exceed 2 mm. When the clearance is larger, you are not sufficiently protected against sparking. The workpiece can be drawn in by the ro- tational motion of the grinding wheel and lead to injuries. Replace the grinding wheel when the holder of the spark guard 9 can no longer be adjusted to the required clearance of 2 mm (max.) to the grinding wheel. Changing a Grinding Wheel Before any work on the machine itself, pull the mains plug. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Ac- cessories running faster than their rated speed can break and fly apart. Replace the grinding wheel as soon as its residual material reaches a thickness of 10 mm. – Loosen the 3 screws of cover 1 and remove cover 1. Hold the grinding wheel wearing protective gloves and un- screw the clamping nut 2 from the grinder spindle 5. Note: The grinder spindle 5 on the left side of the machine has a left-hand thread. – Remove the clamping flange 3 and the grinding wheel from the grinder spindle 5. – The new grinding wheel is mounted in reverse order. Place the cover 1 firmly onto the housing and tighten with the 3 screws. Dress used and out-of-centre grinding wheels with a whet- stone (accessory) before continuing to use them.
