When turning the rotary hammer on while the dust collector (B) is detached
from a concrete surface, the 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 the dust collector (B) attached to a drill bit that has more
than 7-15/32" (190 mm) of overall length, the dust collector (B) cannot touch the
concrete surface and will rotate. Therefore please use the dust collector (B) by
attaching to drill 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 the dust collector (B).
7. Selecting the driver bit
Screw heads or bits will be damaged unless a bit appropriate for the screw diam-
eter is employed to drive in the screws.
8. 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
1. Switch operation
The rotational speed of the drill bit can be controlled 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. Ro Striking
This rotary hammer can be set to
rotation and striking mode by rotat-
ing the change lever fully counter-
clockwise to mark. (Fig. 6)
(1)Mount the drill bit.
(2)Pull the trigger switch after apply-
ing the drill bit tip to the drilling
position (Fig. 7)
