PRIOR TO OPERATION

1. Setting up and checking the work environmentCheck if the work environment is suitable byfollowing the precautions.

HOW TO USE

1. Confirm the cap position (see Fig. 4)The tightening torque of this unit can be adjustedaccording to the cap position, at which the cap isset.

(1) When using this unit as a screwdriver, line up theone of the numbers “1, 3, 5 ... 22” on the cap, orthe white dots, with the triangle mark on the outerbody.

(2) When using this unit as a drill, align the cap drillmark “ ” with the triangle mark on the outerbody.

CAUTIONS� The cap cannot be set between the numerals “1,

3, 5 ... 22” or the white dots.� Do not use with the cap numeral between “22” and

the white line at the middle of the drill mark. Doingso may cause damage. (See Fig. 5)

2. Tightening torque adjustment(1) Tightening torque

Tightening torque should correspond in its intensityto the screw diameter. When too strong torque isused, the screw head may be broken or be injured.Be sure to adjust the cap position according to thescrew diameter.

(2) Tightening torque indicationThe tightening torque differs depending on the typeof screw and the material being tightened.The unit indicates the tightening torque with thenumbers “1, 3, 5 ... 22” on the cap, and a whitedots. The tightening toque at position “1” is the

weakest and the torque is strongest at the highestnumber. (See Fig. 4)

(3) Adjusting the tightening torqueRotate the cap and line up the numbers “1, 3, 5,... 22” on the cap, or the white dots, with thetriangle mark on the outer body. Adjust the cap inthe weak or the strong torque direction accordingto the torque you need.

CAUTIONS� The motor rotation may be locked to cease while

the unit is used as drill. While operating the driverdrill, take care not to lock the motor.

� Too long hammering may cause the screw brokendue to excessive tightening.

3. Change rotation speedOperate the shift knob to change the rotationalspeed. Move the shift knob in the direction of thearrow (see Figs. 6 and 7).When the shift knob is set to “LOW”, the drillrotates at a low speed. When set to “HIGH”, thedrill rotates at a high speed.

CAUTION� When changing the rotational speed with the shift

knob, confirm that the switch is off.Changing the speed while the motor is rotating willdamage the gears.

� When setting the shift knob to “HIGH” (high speed)and the position of the cap is “17” or “22”, it mayhappen that the clutch does not engage and thatthe motor is locked. In such a case, please set theshift knob to “LOW” (low speed).

� If the motor is locked, immediately turn the poweroff. If the motor is locked for a while, the motoror battery may be burnt.

4. The scope and suggestions for usesThe usable scope for various types of work basedon the mechanical structure of this unit is shownin Table 4.

Use Cap PositionRotating speed selection (Position of the shift knob)

LOW (Low speed) HIGH (High speed)

Machine screw 1 – 22 For 4 mm or smallerdiameter screws.

DrivingWood screw 1 – For 8 mm or smaller nominal

diameter screws.

DrillingWood For 27 mm or smaller

diameters.

Metal For drilling with a metalworking drill bit.

For 6 mm or smallerdiameter screws.

For 4.8 mm or smallernominal diameter screws.

For 18 mm or smallerdiameters.

5. How to select tightening torque and rotational speed

Table 5

CAUTION

� The selection examples shown in Table 5 shouldbe considered as general standard. As differenttypes of tightening screws and different materialsto be tightened are used in actual works properadjustments are naturally necessary.

� When using the driver drill with a machine screwat HIGH (high speed), a screw may damage or abit may loose due to the tightning torque is toostrong. 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 sleeveby turning it toward the right (in the clockwisedirection as viewed from the front). (See Fig. 8)

� If the sleeve becomes loose during operation, tightenit further. The tightening force becomes strongerwhen the sleeve is tightened additionally.

(2) Dismounting the bitFirmly grasp the ring and loosen the sleeve byturning it toward the left (in the counter-clockwisedirection 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 thenturn the sleeve to the loose side (left side) whileoperating the clutch. It should be easy now toloosen the sleeve.

7. Confirm that the battery is mounted correctly.

8. Check the rotational direction

The bit rotates clockwise (viewed from the rearside) by pushing the R-side of the selector button.The L-side of the selector button is pushed to turnthe bit counterclockwise. (See Fig. 9). (The L andR marks are provided on the body.)

9. Switch operation

� When the trigger switch is depressed, the toolrotates. When the trigger is released, the tool stops.

� The rotational speed of the drill can be controlledby varying the amount that the trigger switch ispulled. Speed is low when the trigger switch ispulled slightly and increases as the trigger switchis pulled more.

NOTE

� A buzzing noise is produced when the motor isabout to rotate; This is only a noise, not a machinefailure.

MAINTENANCE AND INSPECTION

1. Inspecting the toolSince use of as dull tool will degrade efficiency andcause possible motor malfunction, sharpen orreplace the tool as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensurethat they are properly tightened. Should any of thescrews be loose, retighten them immediately. Failureto do so could result in serious hazard.

3. Cleaning on the outsideWhen the driver drill is stained, wipe with a softdry cloth or a cloth moistened with soapy water.Do not use chloric solvents, gasoline or paint thinner,for they melt plastics.
