5. When driving wood screws (
Fig. 10 on page 33
)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver bit easily slips o
ff
the heads of
minus-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 the wood screw is 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 according
to the depth of the hole and thighten the
knob securely.
7. How to use the drill bit (taper shank) and
the taper shank adapter
(1) Mount the taper shank adapter to the rotary
hammer (
Fig. 12
).
(2) Mount the drill bit (taper shank) to the taper shank
adapter (
Fig. 12
).
(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 adapter
and strike the head of the cotter with a hammer
supporting on a rests (
Fig. 13
).
