Screwdriving operation

First, turn the action mode changing ring so that the arrow on the tool body points to the marking. Adjust the adjusting ring to the proper torque level for your work. Then proceed as follows.
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.
Nominal diameter of wood screw | Recommended size of pilot hole |
3.1mm (1/8") | 2.0mm - 2.2mm (5/64" - 3/32") |

•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.
•Always secure small workpieces in a vise or with a similar
•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 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 to make a hole, make an indentation with a
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.
MAINTENANCE
CAUTION:
•Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
•Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

1. Limit mark
First, turn the adjusting ring so that the pointer points to
the marking. Then proceed as follows.
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.

Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes.
Use a screwdriver to remove two screws then remove the rear cover.
