5. How to select tightening torque and rotational speed
Use
Machine screw
Driving
Wood screw
Wood
Drilling
Metal
CAUTION
The selection examples shown in Table 4 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.
When using the driver drill with a machine screw
at HIGH (high speed), a screw may damage or a
bit may loose due to the tightning torque is too
strong. Use the driver drill at LOW (low speed)
when using a machine screw.
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. 9).
If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened additionally.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by
turning it toward the left (in the counter-clockwise
direction as viewed from the front) (See Fig. 9).
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 11, and then
turn the sleeve to the loose side (left side) while
operating the clutch. It should be easy now to
loosen the sleeve.
7. Confirm that the battery is mounted correctly
8. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise (See Fig. 10) (The
R
marks are provided on the body).
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.

10. Using the hook
CAUTION
The hook can be installed on the right or left side and
the angle can be adjusted in 5 steps between 0° and
80°.
(1) Operating the hook
(2) Switching the hook position
CAUTION

NOTE
(3) Using the bit holder (Hook with bit holder)
HIGH (High speed)
For 6 mm or smaller
diameter screws.
For 3.8 mm or smaller
nominal diameter screws.
For 12 mm or smaller
diameters.
A buzzing noise is produced when the motor is
about to rotate; This is only a noise, not a machine
failure.
When using the hook, pay sufficient attention so
that the main equipment does not fall. If the tool
falls, there is a risk of accident.
Do not attach the tip tool except phillips bit to the
tool main unit when carrying the tool main unit with
the hook suspended from a waist belt.
Injury may result if you carry the equipment
suspended from the waist belt with sharp tipped
components such as drill bit attached.
(a) Pull out the hook toward you in the direction
of arrow (A) and turn in the direction of arrow
(B) (Fig. 11).
(b) The angle can be adjusted in 5 steps (0°, 20°,
40°, 60°, 80°).
Adjust the angle of the hook to the desired
position for use.
Incomplete installation of the hook may result in
bodily injury when used.
(a) Securely hold the main unit and remove the
screw using a slotted head screwdriver or a coin
(Fig. 12).
(b) Remove the hook and spring (Fig. 13).
(c) Install the hook and spring on the other side and
securely fasten with screw (Fig. 14).
Pay attention to the spring orientation. Install the
spring with larger diameter away from you (Fig. 14).
Installing the bit
Slide the bit from the side and then insert firmly
until the groove on the bit locks in the protruded
section of the hook.
