How to Clip or Crutch 

By applying the drill bit tip to the chipping or crushing position, operate the drill by utilising its own weight. 
Forcibly pressing or thrusting is unnecessary. 

Drilling and Driving-In Operations for Self-Drilling Anchors 

When self-drilling anchors (Fig. 4 in the 

Illustrative Guide

 above) are used, the anchors can be driven in. In this 

case, use the optional accessories for self-drilling anchors such as the anchor adapter. 

When an Impact Anchor Adapter is Used 

1.  Attach the running handle to the anchor adapter and create a base hole by applying the drill impact to the 

position of the hole while manually turning the handle (Fig. 5 in the 

Illustrative Guide

 above). 

In this case, the plug is not attached to the anchor. 

2.  When a predetermined depth has been attained, pull out the anchor tentatively (Fig. 6 in the 

Illustrative 

Guide

 above). 

3.  By employing a syringe, blow out the chips. 

4.  Attach the plug to the anchor tip and drive in the anchor again with the Electric Jackhammer. 

5.  After driving in the anchor, use the drift key to separate the anchor (Fig. 7 in th

Illustrative Guide

 above). 

6.  By employing a manual hammer or pliers, snap off the tapered portion of the anchor (Fig. 8 in the 

Illustrative 

Guide

 above). 

CAUTION

: Since the snapped off tapered portion will be propelled in the air, pay attention to the snapping 

direction. 

When a Rotation and Impact Anchor Adapter is Used 

1.  Attach a self-drilling anchor to the anchor adapter. 

2.  Turn ON the switch and drill a base hole with the self-drilling anchor. 

At the start of the hole-drilling, slightly tilt the drill to determine the position of the hole. 

3.  After clearing out dust with a syringe, attach the plug to the anchor tip and drive in the anchor with a hand 

hammer. 

4.  For further operation, follow procedures e and f, described above, when an impact anchor adapter is used. 

When a Taper Shank Adapter is Used 

1.  Attach a drill bit with a tapered shank to the taper shank adapter. 

2.  Turn ON the switch, and drill a hole until it reaches the hole depth indicating groove (Fig. 9 in the 

Illustrative 

Guide

 above). 

3.  After cleaning out dust with a syringe, attach a plug to the anchor tip and drive in the anchor with a manual 

hammer or pliers. 

Handling the Core Bit 

When a core bit is used, Iarge calibre holes and blind holes can be drilled. In this case, use optional accessories 
for core bits (such as a centre pin and core bit shank) for a more rational operation. 

Mounting 

CAUTION

: Prior to mounting a core bit, always disconnect the plug from the power supply receptacle. 

1.  Mount the core bit on the core bit shank (Fig. 10 in the 

Illustrative Guide

 above). Before that, apply some oil 

to the screw portion of the core bit shank for to easily dismount it. 

2.  Mount the core bit shank onto the drill main body in the same manner as mounting the drill bit and the bull 

point (Fig. 11 in the 

Illustrative Guide

 above).
