OPERATION
CAUTION:
•Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations.

CAUTION:
•There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole
of control of the tool and potentially severe injury. When drilling in concrete, granite, tile, etc., move the action mode changing lever to the position of 
symbol to use "rotation with hammering" action.
Be sure to use a
Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, 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.

Drilling operation
When drilling in wood, metal or plastic materials, move the action mode changing lever to the position of 
symbol to use "rotation only" action.
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
MAINTENANCE
CAUTION:
•Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
•Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may result.
