CAUTION
○ The selection examples shown in Table 5 should be
considered as general standard. As diff erent types of
tightening screws and diff erent 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 tightening torque is too strong. Use the driver
drill at LOW (low speed) when using a machine screw.
NOTE:
The use of the battery BCL1415 and BCL1815 in a cold
condition (below 0 degree Centigrade) can sometimes
result in the weakened tightening torque and reduced
amount of work.
phenomenon, and returns to normal when the battery
warms up.
6. Mounting and dismounting of the bit
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill chuck,
fi rmly 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 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. 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 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. Confi rm 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. 9) (The
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.
NOTE
A buzzing noise is produced when the motor is about to
rotate; This is only a noise, not a machine failure.
10. Using the hook
CAUTION
○ When using the hook, pay suffi cient 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.
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
(a) Pull out the hook toward you in the direction of arrow
(A) and turn in the direction of arrow (B) (Fig. 10).
(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.
(2) Switching the hook position
CAUTION
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. 11).
(b) Remove the hook and spring (Fig. 12).
(c) Install the hook and spring on the other side and
securely fasten with screw (Fig. 13).
NOTE
Pay attention to the spring orientation. Install the spring
marks
with larger diameter away from you (Fig. 13).
