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 a
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 chuck adaptor (D) and bit attached.
5. When driving wood screws (Fig. 10)
(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
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 a wood screw in
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.
6. Using depth gauge (Fig. 11)
(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 ac-
cording to the depth of the hole and
tighten the knob bolt securely.
