CAUTION:
⅜ Exercise care not to excessively prolong driving time, otherwise, the screws may be
damaged by excessive force.
⅜ 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.
⅜ Do not attempt to use the rotary hammer in the rotation and striking function with
chuck adaptor (D) and bit attached.
5. When driving wood screws (Fig. 10)
(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
⅜ 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.
⅜ 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:
⅜ 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. Striking only
This rotary hammer can be set to striking
only mode by pressing the push button
and turning the change lever to mark.
(Fig. 11)
(1) Mount the bull point or cold chisel.
(2) Press the push button and set the change
lever to middle of mark and mark.
(Fig. 12)
Then rotation is released, turn the grip
and adjust the cold chisel to desired
position. (Fig. 13)
(3) Turn the change lever to mark. (Fig. 11)
Then bull point or cold chisel is locked.
