bits which have 6-17/32" (166 mm), 6-19/64" (160 mm) and 4-21/64" (110 mm)
overall length.
Dump particles after every two or three holes when drilling.
Please replace the drill bit after removing dust collector (B).
8. Selecting the driver bit
Screw heads or bits will be damaged should an inappropriate bit for the screw
diameter be employed to drive in the screws.
9. Confirm the direction of bit rotation (Fig. 5)
The bit rotates clockwise (viewed from
the rear side) by pushing the R-side of
the reversing switch lever. The L-side
of the lever is pushed to turn the bit
counterclockwise.
HOW TO USE
CAUTION:
To prevent accidents, make sure to turn the switch off and disconnect the plug
from the receptacle when the drill pits and other various parts are installed or
removed. The power switch should also be turned off during a work break and
after work.
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. To turn the
switch OFF, release the trigger switch
to its original position.
2. Rotation + Striking
This rotary hammer can be set to rota-
tion and striking mode by pressing the
push button and turning the change le-
ver to
mark. (Fig. 6)
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the
drill bit tip to the drilling position (Fig. 7)
(3) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so
that drill dust comes out gradually is just sufficient.
