drill bits which have 6-17/32" (166 mm), 6-19/64" (160 mm) and 4-21/64" (110
mm) overall length.
⅜ Dump particles after every two or three holes when drilling.
⅜ Please replace the drill bit after removing dust collector (B).
8. Selecting the driver bit
Screw heads or bits will be damaged unless a bit appropriate for the screw di-
ameter is employed to drive in the screws.
9. Confirm the direction of bit ro-
tation (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:
⅜ 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.
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 turning the
change lever fully counterclockwise 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.
