Drilling operation

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

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.

To prevent the bit from slipping when starting a hole, make an indentation with

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.

stuck bit can be removed simply by setting the reversing switch to reverse rotation

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 hold-down 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.
