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.

Drilling operation

First, turn the adjusting ring so that the pointer on the adjusting ring points to the

-8.-

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

a t

the point to be drilled place the point of the bit in the indenta-

tion 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 a t 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

firmly.

Always secure small workpieces in a vise or similar hold-down device.
