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 as soon
as the clutch cuts in.

Make sure that the driver bit is inserted straight in the screw head, or the screw and/or
bit may be damaged.

Drilling operation
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
centerpunch and hammer a t 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 i s
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 i t firmly.
Always secure small workpieces in a vise or similar hold-down device.
