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. 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.
