The bit can be secured at the desired angle. To change the bit angle, depress the lock button and rotate the action mode changing knob to the O symbol. Turn the bit to the desired angle.
Depress the lock button and rotate the action mode changing knob to the 
symbol. Then make sure that the bit is securely held in place by turning it slightly.

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 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
The depth gauge is convenient for drilling holes of uniform depth. Loosen the side grip and insert the depth gauge into the hole in the side grip. Adjust the depth gauge to the desired depth and tighten the side grip.
NOTE:
•The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing.
Dust cup

Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. Attach the dust cup to the bit as shown in the figure. The size of bits which the dust cup can be
and normal drilling may be resumed.
CAUTION:
•There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole
NOTE:
Eccentricity in the bit rotation may occur while operating the tool with no load. The tool automatically centers itself during operation. This does not affect the drilling precision.
