MAINTENANCE
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
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.
•Always secure small workpieces in a vise or similar hold- down device.
•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.
CAUTION:
•Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
