○ If the bull point or cold chisel is used at the position of “rotation hammering”, the tool can start to
rotate, resulting in unexpected accidents. Make sure that they are used at the position of
“hammering”.
(1) Switching to “hammering”
(a) Push the locked Pushbutton, release lock and turn the function knob counterclockwise.
(b) Align ▲ of the function knob and
of the left cover as illustrated in Fig. 6.
(c) Release the locked Pushbutton to lock the function knob.
NOTE:
Turn the function knob (do not push the locked Pushbutton) to check if it is completely locked and
make sure that it does not turn.
(2)When fixing working positions of tools such as cold chisel, etc.,
(a) Push the locked Pushbutton, release lock and turn the function knob.
(b) Align ▲ of the function knob and
of the left cover as illustrated in Fig. 7.
(c) Release the locked Pushbutton to lock the function knob.
(d) Turn the flex sheath as illustrated in Fig. 8 and fix the tool to the desired working direction.
(e) Switch the selector lever to “hammering” according to the procedures mentioned in the above
item (1) and secure the position of the tool.
5. Install the Orientation Staff Guage (Fig. 9)
(1) Loosen the side handle and insert the straight portion of the orientation staff guage into the handle
bolt hole.
(2) Move the orientation staff guage to the specified position and rotate the grip of the side handle
clockwise to fix the orientation staff guage.
6. Warming up (Fig. 10)
The grease lubrication system in this unit may require warming up in cold regions.
Position the end of the bit so makes contact with the concrete, turn on the switch and perform the
warming up operation. Make sure that a hitting sound is produced and then use the unit.
CAUTION:
When the warming up operation is performed, hold the side handle and the main body
securely with both hands to maintain a secure grip and be careful not to twist your body by the
jammed drill bit.
HOW TO HANDLE A CORE BIT
When a core bit is used, large diameter holes and blind holes can be drilled. In this case, use optional
accessories for core bits (such as a dill bit and core bit shank) for more efficient operation.
1. 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. 11) Before that, feed oil the screw portion of core bit
shank for easy dismounting .
(2) Mount the core bit shank on the main body in the same manner as in mounting the drill bit and the
bull point. (Fig. 12)
(3) Fit in the dill bit by aligning its screw portion with the core bit tip. When the position of the
concave is shifted by turning the turn dill bit clockwise, the dill bit never slips off even when the
drill is used in a downward direction.(Fig. 13)
2. Drilling holes
(1) Insert the plug into a receptacle.
(2) By straightly and gently pressing dill bit to the wall or floor surface, the entire surface of the core
bit tip attains contact to start the hole drilling job. (Fig. 14)
