5. When driving wood screws (Fig. 11)
(1) Selecting a suitable driver bit
Employ phillips screws, if possible, since the driver
bit easily slips off the heads of slotted-head screws.
(2) Driving in wood screws
䡬
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.
䡬
After rotating the rotary hammer at low speed for a
while until a wood screw in partly driven into the
wood, squeeze the trigger more strongly to obtain
the optimum driving force.
CAUTION:
䡬
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.
6. Hammering only
This rotary hammer can be set to hammering only
mode by turning the change lever to mark. (Fig.
12)
(1) Mount the bull point or cold chisel.
(2) Set the change lever to middle of
mark and
mark. (Fig. 13)
The rotation is released, turn the grip and adjust
the cold chisel to desired position. (Fig. 14)

Then bull point or cold chisel is locked.
7. Using depth gauge (Fig. 15)
(1) Loosen the knob on the side handle, and insert the
depth gauge into the mounting hole on the side
handle.
(2) Adjust the depth gauge position according to the
depth of the hole and tighten the knob bolt securely.
8. How to use the drill bit (taper shank) and the taper
shank adaptor.
(1) Mount the taper shank adaptor to the rotary
hammer. (Fig. 16)
(2) Mount the drill bit (taper shank) to the taper shank
adaptor. (Fig. 16)
(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 adaptor and strike
the head of the cotter with a hammer supporting
on the rests. (Fig. 17)
