OPERATION
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 switch trigger as soon as
the clutch cuts in.
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 prevent splitting of the workpiece.
See the chart.
•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.
Drilling operation
First, turn the adjusting ring so that the pointer points to the
marking. 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.
