Drilling operation
First, turn the adjusting ring so that the pointer on the adjusting ring points to the st- marking. Then proceed as follows.
*Drilling in wood
When drilling in wood, 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 a t the point to be drilled place the point of the bit in the indenta- tion 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 a t the time of hole breakthrough. 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
Overload protector
The overload protector automatically cuts out to break the circuit whenever heavy work i s prolonged. Wait
CAUTION :
Always withdraw the tool from the workpiece before resuming operation. If the tool cannot be withdrawn, hold the tool firmly when turning on the tool, to overcome a strong reaction.
Hook
A hook is provided as a standard equip-
ment. This hook is convenient for tem- Hook porarily hanging the tool. To install the
hook, first insert one end of the hook into one slot in the tool body and then insert the other end into the other slot. Secure the hook with the screw. The hook can be installed on either left or right side of the
tool.
