[. . . ] Michigan Drive, Tongwell, Milton Keynes, Bucks MK15 8JD, ENGLAND 2 SAFETY INSTRUCTIONS ENA001-2 WARNING: When using electric tools, basic safety precautions, including the following, should always be followed to reduce the risk of fire, electric shock and personal injury. Read all these instructions before operating this product and save these instructions. For safe operations: 1. Do not use power tools where there is risk to cause fire or explosion. When not in use, tools should be stored in a dry, high or locked up place, out of reach of children. [. . . ] Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. Make sure the bit is not contacting the workpiece before the switch is turned on. Watch for vibration or wobbling that could indicate improperly installed bit. ENB033-2 10. Always switch off and wait for the bit to come to a complete stop before removing the tool from workpiece. Do not touch the bit immediately after operation; it may be extremely hot and could burn your skin. Always lead the power supply cord away from the tool towards the rear. Do not smear the tool base carelessly with thinner, gasoline, oil or the like. Draw attention to the need to use cutters of the correct shank diameter and which are suitable for the speed of the tool. 2. 9. SAVE THESE INSTRUCTIONS 4 FUNCTIONAL DESCRIPTION 003252 · CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Adjusting the depth of cut Place the tool on a flat surface. Loosen the lock lever and lower the tool body until the bit just touches the flat surface. Depth pointer Screw Stopper pole Adjusting hex bolt Stopper block Next, lower the stopper pole until it makes contact with the adjusting hex bolt. The depth of cut is indicated on the scale (1 mm per graduation) by the depth pointer. Now, your predetermined depth of cut can be obtained by loosening the lock lever and then lowering the tool body until the stopper pole makes contact with the adjusting hex bolt. CAUTION: Since excessive cutting may cause overload of the motor or difficulty in controlling the tool, the depth of cut should not be more than 15 mm at a pass when cutting grooves with an 8 mm diameter bit. When cutting grooves with a 20 mm diameter bit, the depth of cut should not be more than 5 mm at a pass. When you wish to cut grooves more than 15 mm deep with an 8 mm diameter bit or more than 5 mm deep with a 20 mm diameter bit, make several passes with progressively deeper bit settings. · · 5 005083 Stopper block The stopper block has three adjusting hex bolts which raise or lower 0. 8 mm per turn. You can easily obtain three different depths of cut using these adjusting hex bolts without readjusting the stopper pole. Adjust the lowest hex bolt to obtain the deepest depth of cut, following the method of "Adjusting depth of cut". The differences in height of these hex bolts are equal to the differences in depths of cut. To adjust the hex bolts, first loosen the hex nuts on the hex bolts with the wrench and then turn the hex bolts. After obtaining the desired position, tighten the hex nuts while holding the hex bolts in that desired position. The stopper block is also convenient for making three passes with progressively deeper bit settings when cutting deep grooves. [. . . ] Allow for the distance (X) between the bit and the outside of the templet guide. The distance (X) can be calculated by using the following equation: Distance (X) = (outside diameter of the templet guide - bit diameter) / 2 005073 Vacuum head set (Accessory) Use the vacuum head for dust extraction. Install the vacuum head on the tool base using the two screws. 1 1. Screws 005084 Then connect a vacuum cleaner to the vacuum head. 9 MAINTENANCE CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
