(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. 12)
(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.
