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.
