OPERATION

Screwdriving operation

Place the point of the driver bit in the screw head and apply

pressure to the tool. Start the tool slowly and then increase

the speed gradually. Release the trigger just as the screw

bottoms out. If the trigger is not released, the screw may strip

out the hole or the screw and/or bit may be damaged.

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 prevent splitting of the workpiece.

See the chart.

Drilling operation

Drilling in wood

When drilling in wood, the 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 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 force exerted on the tool/bit at the

time of hole break through. Hold the tool firmly and exert

care when the bit begins to break through the workpiece.
