CAUTION
The selection examples shown in Table 2 should
be considered as general standard. As different types
of tightening screws and different materials to be
tightened are used in actual works proper
adjustments are naturally necessary.
6. Mounting and dismounting of the bit.
(1) After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve
by turning it toward the right (in the clockwise
direction as viewed from the front). (See Fig. 8)
If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened.
(2) Dismounting the bit
Firmly grasp t he ring and loosen the sleeve by
turning it toward the left (in the counter-clockwise
direction as viewed from the front). (See Fig. 8)
CAUTION:
When it is no longer possible to loosen the sleeve,
use a vise or similar instrument to secure the bit.
Set the clutch mode between 1 and 3 and then turn
the sleeve to the loose side (left side) while operating
the clutch. It should be easy now to loosen the
sleeve.

4. The scope and suggestions for uses
The usable scope for various types of work based
on the mechanical structure of this unit is shown
in Table 1.
Use for drilling purpose.
Use the bit and socket matching the screw
diameter.
Use after drilling a preparatory hole.
NOTE
There is a plus driver bit and a minus driver bit
on bith sides of the main unit.
The bits can be removed by pulling them forward.
After using the bits, make sure to firmly attach them
to the main unit again. (Fig. 9)
7. Confirm that the battery is mounted correctly.
8. Check the rotational direction
When the reversing switch is set to
rotates clockwise when viewed from the drill rear.
When set to , the drill rotates counterclockwise
(see Fig. 10). (The
on the body.)
CAUTION:
Make sure to firmly switch the reversing switch. If
it is not switched firmly, the drill may not rotate
even if the switch is turned on.
9. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
The rotational speed of the drill can be controlled
by varying the amount that the trigger switch is
pulled. Speed is low when the trigger switch is
pulled slightly and increases as the trigger switch
is pulled more.
Suggestions
HIGH (High speed)
For 5 mm or larger diameter
screws.
For 3.8 mm or larger nominal
diameter screws.
For 10 mm or smaller
diameters.
