6.12.1. First, slide the action mode change lever so that it points to the
6.12.2. The adjusting ring can be aligned in any torque levels for this operation.
6.12.3. Be sure to use a tungsten-carbide tipped bit.
6.12.4. Position the bit at the desired location for the hole, then pull the switch trigger.
6.12.5. Do not force the tool. Light pressure gives best results.
6.12.6. Keep the tool in position and prevent it from slipping away from the hole.
6.12.7. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead,
run the tool at an idle, and then remove the bit partially from the hole. By repeating this
several times, the hole will be cleaned out and normal drilling may be resumed.
6.13. Screw driving operations.
6.13.1. First, slide the action mode change lever so that it points to the
6.13.2. Adjust the adjusting ring to the proper torque level for your work.
6.13.3. Then proceed as follows. Place the point of the driver bit in the screw head and apply
pressure to the tool.
6.13.4. Start the tool slowly and then increase the speed gradually.
6.13.5. Release the switch trigger as soon as the clutch cuts in.
6.14. Drilling.
6.14.1. There is a tremendous force exerted on the tool/bit at the time of breaking through the
hole. Hold the tool firmly and exert care when the bit begins to break through the work piece.
6.14.2. 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.
6.14.3. Always secure small work pieces in a vice or similar hold-down device.
6.14.4. 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.
6.14.5. First, slide the action mode change lever so that it points to the
ring can be aligned in any torque levels for this operation. Then proceed as follows.
6.15. Drilling into wood.
6.15.1. 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 work piece.

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 screw, predrilled a pilot hole 2/3 the diameter of the screw. It
makes driving easier and prevents splitting of the work piece.
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.
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.
