OPERATION
Hammer drilling operation
010167 |
Set the action mode changing knob to the 
symbol. 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
Chipping/Scaling/Demolition
010168
Set the action mode changing knob to the 
symbol. Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency.
Drilling in wood or metal
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.
CAUTION:
• | There is tremendous and sudden twisting force |

Use the
Use the optional drill chuck assembly. When installing it, refer to "Installing or removing drill bit" described on the previous page.
Set the action mode changing knob to the 
symbol. You can drill up to 13 mm diameter in metal and up to 32 mm diameter in wood.
CAUTION:
•Never use "rotation with hammering" when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged.
Also, the drill chuck will come off when reversing the tool.
•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 twisting force exerted on the tool/bit at 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.
