HOW TO USE
1.How to drill holes (Fig. 4)
(1) Use the Bar type handle.
Do not use D type handle when drilling operation, since it may not be enough to hold the body firmly.
(2) Pull the switch trigger after applying the drill bit tip to the drilling position.
(3) It is unnecessary to forcibly press the Rotary Hammer main body. It is sufficient to slightly press the rotary hammer to an extent that clips are freely discharged.
CAUTION:
Although this machine is equipped with a safety clutch, if the drill bit becomes bound in concrete or other material, the resultant stoppage of the drill bit could cause the machine body to turn in reaction. Ensure that the main handle and bar type handle are gripped firmly during operation.
