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 attached to is as follows.
| Bit diameter |
Dust cup 5 | 6 mm - 14.5 mm |
Dust cup 9 | 12 mm - 16 mm |

OPERATION
Hammer drilling operation
007953
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
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.

After drilling the hole, use the
Chipping/Scaling/Demolition

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.
