5. How to select tightening torque and rotational speed

Table 8

CAUTION

⅜ 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.

⅜ 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

(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).

⅜ 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).

(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).

⅜ 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

and

marks are provided on the body).

9. Switch operation

⅜ When the trigger switch is depressed, the tool

rotates. When the trigger is released, the tool stops.

⅜ 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

⅜ 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.

⅜ 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.
