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 hammering function
with chuck adaptor (D) and bit attached.
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
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.
