5. How to select tightening torque and rotational speed

Metal
CAUTION
The selection examples shown in Table 8 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 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, BCL1430, EBL1430,
BCL1815, EBM1430 and EBM1830 in a cold condition
(below 0 degree Centigrade) can sometimes result
in the weakened tightening torque and reduced
amount of work. This, however, is a temporary
phenomenon, and returns to normal when the
battery warms up.
6. Mounting and dismounting of the bit
<For double sleeve chuck>
(1) Mounting the bit
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).
<For single sleeve chuck>
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front) to open the clip on the keyless chuck. After
inserting a driver bit, etc., into the keyless drill
chuck, and tighten the sleeve by turning it toward
the right (in the clockwise direction as viewed from
the front) (See Fig. 10).

For 4.8 mm or smaller
nominal diameter screws.
(DS18DFL)
For 3.8 mm or smaller
nominal diameter screws.
(DS14DFL)
For 24 mm or smaller
diameters. (DS18DFL)
For 12 mm or smaller
diameters. (DS14DFL)
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
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front), and then take out the bit, etc (See Fig. 10).
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. 11) (The
marks are provided on the body).
R
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 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.
