OPERATOR'S MANUAL
HAMMER DRILL - 1/2 in. (13 mm)
D550H
VARIABLE SPEED – DOUBLE INSULATED
EXTENSION CORD CAUTION
When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An under- sized cord will cause a drop in line voltage, resulting in over- heating and loss of power. Use the chart to determine the mini- mum wire size required in an extension cord. Only round jack- eted cords should be used.
When working with a tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters "WA" on the cord's jacket.
Before using any extension cord, inspect it for loose or ex- posed wires and cut or worn insulation.
