NOTE:
*Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged.
*When driving wood screws, predrill pilot holes to make driving easier and to pre- vent splitting of the workpiece. See the chart.

*If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.
Drilling operation
First, turn the adjusting ring so that the pointer on the tool body points to the fi marking. Then proceed as follows.
*Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.
*Drilling in metal
To prevent the bit from slipping when starting a hole, make an indentation with a center- punch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.
CAUTION:
*Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pres- sure 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 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 reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly.
*Always secure small workpieces in a vise or similar holddown device.
*If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.
