CAUTION:
•
Adjust the adjusting ring to the proper torque level for your work.
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
switch trigger as soon as the clutch cuts in.
CAUTION:
•
Make sure that the driver bit is inserted straight in the screw head, or the
screw and/or bit may be damaged.
NOTE:
•
When driving wood screws, predrill pilot holes to make driving easier and
to prevent splitting of the workpiece. See the chart.

Drilling operation
First, turn the adjusting ring so that the pointer points to the
proceed as follows.
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.
•
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.
