NOTES TO USERS CHECK THE FOLLOWING BEFORE STARTING OPERATION.
OPERATING INSTRUCTIONS A. Machine Installation DRILLING POSITION ANCHOR APPROX.200mm HEX.
B.
C. Start Drilling NOTE: Never fail to supply water onto DIAMOND BIT. The operation without water will damages bit tip. 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: While drilling through rebar, CIRCUIT PROTECTOR might be energizes, causing motor stop.
NOTE: While current are not achieve indicate current of this machine but clutch idling, means DIAMOND BIT idling but motor still operating, then you have to do adjustment as following: Clutch adjust hole.
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 generated and 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 hammer or chisel and remove the stuck core by chipping little by little.
