PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
3. Extension cord
When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Mounting the drill bit (Fig. 1)
CAUTION
To prevent accidents, make sure to turn the switch off
and disconnect the plug from the receptacle.
NOTE
When using tools such as bull points, drill bits, etc.,
make sure to use the genuine parts designated by our
company.
(1) Clean the shank portion of the drill bit.
(2) Insert the drill bit in a twisting manner into the tool
holder until it latches itself (Fig. 1).
(3) Check the latching by pulling on the drill bit.
(4) To remove the drill bit, fully pull the grip in the direction
of the arrow and pull out the drill bit (Fig. 2).
5. Installation of dust cup or dust collector (B)
(Optional accessories) (Fig. 3, Fig. 4)
When using a rotary hammer for upward drilling
operations attach a dust cup or dust collector (B) to
collect dust or particles for easy operation.
○ Installing the dust cup
Use the dust cup by attaching to the drill bit as shown in
Fig. 3.
When using a bit which has big diameter, enlarge the
center hole of the dust cup with this rotary hammer.
○ Installing dust collector (B)
When using dust collector (B), insert dust collector (B)
from the tip of the bit by aligning it to the groove on the
grip (Fig. 4).
CAUTION
○ The dust cup and dust collector (B) are for exclusive
use of concrete drilling work. Do not use them for wood
or metal drilling work.
9
○ Insert dust collector (B) completely into the chuck part
of the main unit.
○ 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. Confi rm the direction of bit rotation (Fig. 5)
The bit rotates clockwise (viewed from the rear side) by
pushing the R-side of the push button.
The L-side of the push button is pushed to turn the bit
counterclockwise.
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.
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.
