English
When turning the rotary hammer on while dust collector (B) is detached from a concrete surface, dust collector (B) will rotate together with the drill bit. Make sure to turn on the switch after pressing the dust cup on the concrete surface. (When using dust collector (B) attached to a drill bit that has more than 190 mm of overall length, dust collector
(B) cannot touch the concrete surface and will rotate. Therefore please use dust collector (B) by attaching to drill bits which have 166 mm, 160 mm, and 110 mm overall length.)
Dump particles after every two or three holes when drilling.
Please replace the drill bit after removing dust
collector (B).
6.Selecting the driver bit
Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is employed to drive in the screws.
7.Confirm the direction of bit rotation (Fig. 5) The bit rotates clockwise (viewed from the rear side) by pushing the
Push button
Fig. 5
8.Selecting the function mode
You can switch functions to the 3 modes of “hammering only, “rotation + hammering”, and
“rotation only” by turning the change lever while pressing the push button. Set the ▲ mark position of the change lever to that of the mode to be used.
CAUTION:
Before operating the change lever, check and make sure that the motor has stopped.
A failure can occur if it is operated while the motor is running.
To operate the change lever, press the push button, and release the lock of the change lever. Also, check and make sure after operation that the push button has returned and that the change lever has been locked.
Switch the change lever without mistake. If it is used at a position halfway, there is a fear that the service life of the switching mechanism may be shortened.
9.RCD
The use of a residual current device with a rated residual Current of 30mA or less at all times is recommended.
HOW TO USE
CAUTION:
To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill bits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.
NOTE:
Ensure that the wing bolt in the side handle is properly tightened before using the tool.
1.Switch operation
The rotation speed of the drill bit can be controlled steplessly by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the switch is pulled more.
However, the switch trigger can only be pulled in halfway during reverse and rotates at half the speed of forward operation.
2.Rotation + hammering
This rotary hammer can be set to rotation and
hammering mode by pressing the push button and
turning the change lever to the 
mark (Fig. 6). Turn the grip slightly and confirm that the clutch has been engaged with a click.

(3)Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes out gradually is sufficient.
CAUTION:
When the drill bit touches construction iron bar, the bit will stop immediately and the rotary hammer will react to revolve. Therefore grip the side handle and handle tightly as shown in Fig. 7.
