4. When driving wood screws (Fig. 14)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver bit
easily slips off the heads of slotted-head screws.
(2) Tightening wood screws
Prior to tightening 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 in the holes.
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.
5. Using depth gauge (Fig. 15)
(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.
6. How to use the drill bit (taper shank) and the taper
shank adapter
(1) Mount the taper shank adapter to the rotary hammer.
(Fig. 16)
(2) Mount the drill bit (taper shank) to the taper shank
adapter. (Fig. 16)
(3) Turn the switch ON, and drill a hole to 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 the
rest. (Fig. 17)
7. Switching between the "SAVE" and the "POWER"
modes
The hammering force of the hammer can be
increased or decreased to conform with intended
usage, by operating the shift knob as per Fig. 18.
Adjust the force to match the usage intended.
(1) "SAVE" mode ... decreased hammering force
This can prevent thin drill bits which are less than
4.3 mm in diameter, from being bent or broken.
