OPERATION

Screwdriving operation

For model 6017D/6018D
Place the point of the driver bit in the screw
head and apply pressure to the tool. Start
the tool. 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.
For model 6019D
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.

First, turn the adjusting ring so that the
pointer points to the
Then 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.
