Pulling the trigger switch and pushing
the stopper, it keeps the switched-on con-
dition which is convenient for continuous
running. When switching off, the stopper
can be disconnected by pulling the trig-
ger again.
2. When using as a Drill or a Hammer Drill
(1) Pressing force of the drill
You cannot drill holes more quickly even if you press the drill with a stronger force than
necessary. It not only damages tip of drill bits and decreases the efficiency of operation,
but also shortens the life of the drill.
(2) In case of penetrating holes
Drill bits can be broken when the material being drilled is penetrated. It is important to
decrease pressing force just before penetrating.
CAUTION : In continuous operation, conduct no-load operation for five seconds after
completing a drilling job.
WARNING:
When a thick drill bit is used, your arm is subjected to larger reaction
force. Be careful not to be moved by the reaction force. For this,
establish a foothold, hold the unit tightly with both hands perpendicularly
to the material being drilled.
3. When driving wood screws
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver bit easily slips off 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 driver bit at low speed for a while until a wood screw is partly driven
into the wood, squeeze the trigger more strongly to obtain the optimum driving force.
NOTE:
Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness
of the wood into consideration. Should the hole the excessively small or shallow,
requiring much power to drive the screw into it, the thread of the wood screw may
sometimes be damaged.
