CAUTION
● Exercise care not to excessively prolong driving
time, otherwise, the screws may be damaged by
excessive force.
● Apply the rotary hammer perpendicularly to the
screw head when driving the screw; otherwise,
the screw head or bit will be damaged, or driving
force will not be fully transferred to the screw.
● Do not attempt to use the rotary hammer in the
rotation and striking function with the chuck
adapter and bit attached.
5. When driving wood screws (Fig. 18)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver
bit easily slips off the heads of minus-head screws.
(2) Driving in wood screws.
○ Prior to driving in wood screws, make pilot holes
suitable for them in the wooden board.
Apply the bit to the screw head grooves and gently
drive the screws into the holes.
○ After rotating the rotary hammer at low speed for a
while until the wood screw is partly driven into the
wood, squeeze the trigger more strongly to obtain the
optimum driving force.
CAUTION
Exercise care in preparing a pilot hole suitable
for the wood screw taking the hardness of the
wood into consideration. Should the hole be
excessively small or shallow, requiring much
power to drive the screw into it, the thread of the
wood screw may sometimes be damaged.

7. Using depth gauge (Fig. 22)
(1) Loosen the knob on the side handle, and insert the
depth gauge into the mounting hole on the side

8. How to use the drill bit (taper shank) and the taper
shank adapter
(1) Mount the taper shank adapter to the rotary hammer
(Fig. 23).
(2) Mount the drill bit (taper shank) to the taper shank
adapter (Fig. 23).
(3) Turn the switch ON, and drill a hole in prescribed
depth.
(4) To remove the drill bit (taper shank), insert the cotter
into the slot of the taper shank adapter and strike the
head of the cotter with a hammer supporting on the
rests (Fig.24).
