Rotate the mode selector dial so that the arrow points to the symbol corresponding for the desired mode. Fig. J 7 6 NOTE: The arrow on the mode selector dial 6 must be pointing at a mode symbol at all times. There are no operable positions in between. It may be necessary to briefly run the motor after having changed from 'hammering only' to 'rotary' modes in order to align the gears. Performing an Application (Fig. A, K) WARNING: TO REDUCE THE RISK OF PERSONAL INJURY, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood "back-up" block to prevent damage to the material. WARNING: Always wait until the motor has come to a complete standstill before changing the direction of rotation. 1. Choose and install the appropriate chuck, adapter, and/ or bit onto to the tool. Refer to Bit and Bit Holder. 3 12 5. Place the bit/chisel on the desired location. 6. Depress the trigger switch 5 . The farther you depress the trigger switch, the faster the tool will operate. For maximum tool life, use variable speed only for starting holes or fasteners. NOTE: Depending on your tool, depressing the trigger switch activates a worklight 12 designed to illuminate the immediate work surface. Refer to Components. The worklight will automatically turn off shortly after the trigger switch is released. The worklight is not intended to be used as a flashlight. 7. To stop the hammer, release the switch. Recommendations for Tool Operation • Large (5/16" to 1/2" [7.9 mm to 12.7 mm]) holes in steel can be made easier if a pilot hole (5/32" to 3/16" [4 mm to 4.8 mm]) is drilled first. • When drilling, always apply pressure in a straight line with the bit, but do not push hard enough to stall the motor or deflect the bit. A smooth even flow of material indicates the proper drilling rate. • If drilling thin material or material that is prone to splinter, use a wood "back-up" block to prevent damage to the work piece. WARNING: • Do not use this tool to mix or pump easily combustible or explosive fluids (benzine, alcohol, etc.). • Do not mix or stir inflammable liquids labelled accordingly. 10
