B. Cutter Attachment & Water Supply

WATER COLLECTOR RETAINING FITTING

C. Start Drilling

NOTE: DIAMOND BIT can perform drilling with light force. Do not apply excessive force. Too much force reduces motor speed resulting in slow operation. Excessive force energizes CIRCUIT PROTECTOR. Such operation does not only shorten the life of DIAMOND BIT but also leads to motor failure.

NOTE:Never fail to supply water onto DIAMOND BIT. The operation without water willdamages bit tip.

NOTE: While drilling through rebar, CIRCUIT PROTECTOR might be energizes, causing motor stop. In this case, raise DIAMOND BIT once, get BIT TIP away from the work surface, and then reset SWITCH on. SWITCH can not be reset with BIT TIP rest on the work surface because CIRCUIT PROTECTOR would be energized again.

21

NOTE: While current are not achieve indicate current of this machine but clutchidling, means DIAMOND BIT idling but motor still operating, then you have to doadjustment as following:

Adjust screw

Screwdriver( )

Clutch adjust hole.

Counter turn

about 15 degree

POLE FIXING SCREW

BASE FIXING SCREW

NOTE: Cores often drop from DRILL BIT at the completion of the hole. Use extreme care in operation at high places.NOTE: If POLE & MOTOR is not securely clamped, chattering sound is generatedand it deteriorates the life of DIAMOND BIT extremely. Make frequent clamp adjustments to avoid rattling.NOTE: if core is stuck in DIAMOND BIT at the completion of drilling, use a hammeror chisel and remove the stuck core by chipping little by little.

MAINTENANCE & INSPECTION

CAUTIONBe sure to turn SWITCH off andunplug the machine beforemaintenance and inspection.

NOTE:Dust or dirt inside MOTOR is likely to cause motor failure. After each use, letMOTOR idle and feed air into MOTOR to drive dust and dirt out.

NOTE:In replacement, be sure to use our genuine carbon brush. You can remove carbon brushes by detaching CARBON CAP (see DESCRIPTION) using a straight blade screwdriver. After replacement, tighten CARBON CAP securely.
