Ensure that the operating instructions are with the tool when it is given to other persons. Operating controls ³ Chuck operating lever · Control switch » Water regulation wheel ¿ Switch lock for drill stand use ´ Keyed supply cord plug connection (socket for supply cord plug) ² Water collector holder release button ¶ Slider for water collector holder rod length adjustment º Water collector sleeve ¾ Depth gauge µ Water flow indicator release button General information In these operating instructions, this symbol indicates points of particular importance to safety. [. . . ] ­ As you do so, keep button ² depressed and engage the water collector in position on the gear housing by releasing the button when the rods have been fully inserted . ­ Slide the button ¶ to the right to adjust the water collector to the length corresponding to the core bit used (position 1 < 150 mm working length; position 2 : 300 mm working length) . ­ Always ensure that the diameter of the water collector sleeve used corresponds to the nominal diameter of the core bit used. ­ Always screw the side handle and depth gauge into one of the threaded bushings provided on the gear housing . Inserting the core bit ­ Open the chuck by lifting the operating lever ³ 30° upwards . ­ Check that the core bit connection end and the chuck are clean and undamaged. ­ Check that the slots in the cutting edge of the core bit to be used still have a depth of at least 0. 5 mm. If not, the core bit should be replaced as there is otherwise a risk of it becoming stuck in the hole . ­ Pivot the water collector about its mounting axis as far as it will go. ­ From above, insert the cutting edge of the core bit into the water collector sleeve . 0 l/min. ­ Before beginning drilling, adjust the water regulation wheel to the middle position of its range 1­3. ­ Carefully bring the water collector into contact with the surface where the hole is to be drilled. ­ The core bit can be exactly positioned by bringing the centring marks on the water collector into alignment with a cross marked at the position where the hole is to be drilled . ­ To begin drilling, press the control switch before the core bit has been brought into contact with the base material. ­ Begin drilling the hole only when the water flow indicator shows that water is flowing through the core bit . ­ Take care to ensure that the core bit is perpendicular to the base material. The pressure applied to the core bit should be regulated so that the tool continues to run at its highest speed. Application of higher pressure does not increase the rate of drilling progress. Do not tilt it at angle as this may result in reduced drilling performance. ­ Immediately after beginning drilling, check the water flow rate indicator to ensure that water is flowing (water flow rate is within the optimum range when the red and white segments of the rotating wheel are still individually discernible). Insufficient water may cause the core bit to stick in the hole, resulting in damage to the core bit. It may be necessary to adjust the water flow rate manually while drilling by turning the water regulation wheel .
