Resumen del manual
Now you can use the cold chisel or bull point. CAUTION: • Always use ’’hammering only’’ action when the chisel adapter is installed on the tool. If you use ’’rotation with hammering’’ or ’’rotation only’’ action, a malfunction and damage to the tool will result. Depth gauge The depth gauge is convenient for drilling holes of uniform depth. Insert the depth gauge into the hole in the grip base. Adjust the depth gauge to the desired depth and then tighten the clamp screw to secure the depth gauge. NOTE: • The depth gauge cannot be used at the position where 2. Depth gauge the depth gauge strikes against the tool body. 1 2 3 1. Chisel adapter 2. Clamp screw 3. Chisel 1.

Attach the dust cup to the bit as shown in the figure. Thesizeofbitswhich thedustcup canbeattachedtoisas follows. Bit diameter Dust cup 5 6 mm (1/4”) -14.5 mm (9/16”) Dust cup 9 12 mm (15/32”) -16 mm (5/8”) 1. Dust cup OPERATION Hammer drilling operation Set the action mode changing knob to the symbol. Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. CAUTION: • There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury. 002449 Blow-out bulb (optional accessory) After drilling the hole, use the blow-out bulb to clean the dust out of the hole. 1 1. Blow-out bulb 003219 1 1. Drill chuck assembly MAINTENANCE Chipping/Scaling/Demolition Set the action mode changing knob to the symbol. Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency. Drilling in wood or metal Use the optional drill chuck assembly. When installing it, refer to “Installing or removing the bit” described on the previous page. Set the action mode changing knob to “rotation only”. You can drill up to 13 mm (1/2”) diameter in metal and up to 38 mm (1 -1/2”) diameter in wood. (Note: When using a flat boring bit.) CAUTION: • Never use “rotation with hammering” when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged. Also, the drill chuck will come off when reversing the tool. • Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. • There is a tremendous twisting force exerted on the tool/ bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece. • A stuck bit can be removed simply by setting the reversingswitchtoreverse rotation in ordertobackout. However, the tool may back out abruptly if you do not hold it firmly. • Always secure small workpieces in a vise or similar hold- down device. CAUTION: • Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
