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 impact driver drill with a machine screw

HIGH (high speed), a screw may damage or a bit may

loose due to the tightning torque is too strong. Use the

impact driver drill at LOW (low speed) when using a

machine screw.

NOTE

The use of the battery BCL1415, BCL1815 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.

7. Mounting and dismounting of the bit

(1) 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. 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.

8. Conﬁ rm that the battery is mounted correctly

9. 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

and marks

are provided on the body).

CAUTION

Always use this unit with clockwise rotation, when using it

as an impact drill.

10. 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.

11. For

drilling into brick

Excessive pressing force never increases drilling speed.

It will not only damage the drill tip or reduce working

eﬃ ciency, but could also shorten the service life of

drill bit. Operate the impact driver drill within 10-15 kg

pressing force while drilling into brick.

12. Using the

bit holder

CAUTION

○ Stow the bit in the speciﬁ ed location on the tool. If the tool

is used with the bit stowed improperly, the bit may fall and

cause bodily injury.

○ Do not stow bits that are of a diﬀ erent length, gauge or

dimension than the plus driver bit (65 mm long) included

in the STANDARD ACCESSORIES.

The bit may fall and cause bodily injury.

(1) Removing the bit

Securely hold the main unit and pull out the bit by

holding

the tip with your thumb (Fig. 10).

(2) Installing the Bit

Install the bit with steps opposite of when removing.

Insert the bit so that the right and left sides are equal, as

shown in Fig. 11

MAINTENANCE AND INSPECTION

1. Inspecting the tool

Since use of as dull tool will degrade eﬃ ciency and cause

possible motor malfunction, sharpen or replace the tool

as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the

screws be

loose, retighten them immediately. Failure to do so could

result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very “heart” of the power

tool.

Exercise due care to ensure the winding does not

become damaged and/or wet with oil or water.

4. Cleaning

on the outside

When the impact driver drill is stained, wipe with a soft

dry cloth or a cloth moistened with soapy water. Do not

use chloric solvents, gasoline or paint thinner, for they

melt plastics.

5. Storage

Store the impact driver drill in a place in which the

temperature is

less than 40°C and out of reach of

children.

NOTE

Make sure that the battery is fully charged when stored

for a long period (3 months or more). The battery with

smaller capacity may not be able to be charged when

used, if stored for a long period.
