mounting hole on the side handle.
(2) Adjust the staff gauge position according to the depth of the hole and tighten the papilionaceous
short bolt securely.
5. Warming up (Fig. 7)
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 to the core bit shank. Fig. 8 Lubricate the thread of the core bit shank to facilitate
disassembly.
(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. 9
(3) Fit in the drill bit by aligning its screw portion with the core bit tip. When the position of the concave
is shifted by turning the turn drill bit clockwise, the drill bit never slips off even when the drill is used in
a downward direction. Fig. 10
