How to make the batteries perform longer.

(1) Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

• When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 rest until the next charging.
• If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (off for 0.5 seconds). In such a case, first let the battery cool, then start charging.
• When the pilot lamp fl ickers (at 0.2-second intervals), check for and take out any foreign objects in the charger's battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

- Since the built-in micro computer takes about 3 seconds to confi rm that the battery being charged with UC18YKSL is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.

Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

The tightening torque differs depending on the type of screw and the material being tightened.

The unit indicates the tightening torque with the numbers "1, 4, 7 ... 22" on the cap, and the black dots. The tightening torque at position "1" is the weakest and the torque is strongest at the highest number.

(3) Adjusting the tightening torque

Rotate the clutch dial and line up the numbers "1, 4, 7 ... 22" on the clutch dial, or the black dots, with the triangle mark on the outer body. Adjust the clutch dial in the weak or the strong torque direction according to the torque you need.

CAUTION

● The motor rotation may be locked to cease while the unit is used as drill. While operating the hammer drill take care not to lock the motor.

● Too long hammering may cause the screw broken due to excessive tightening.

3. Rotation to Impact changeover (See Fig. 5)

The “Rotation (Rotation only)” and “Hammer (Hammer + Rotation)” can be switched by aligning the drill mark “” or the hammer mark “T with the triangle mark on the outer body.

To make holes in the metal, wood or plastic, switch to "Rotation (Rotation only)".

To make holes in bricks or concrete blocks, switch to "Hammer (Hammer + Rotation)".

CAUTION

- If an operation which is normally performed at the "Rotation" setting is performed at "Hammer" setting, the effect of making holes does not only increase but it may also damage the bit or other parts.

- If it is hard to turn the cap to hammer mark "T" position, turn the chuck slightly in either direction and then turn the cap to hammer mark "T" position again.

4. Change rotation speed

Operate the shift knob to change the rotational speed. Move the shift knob in the direction of the arrow (see Figs. 7 and 8).

When the shift knob is set to "LOW", the drill rotates at a low speed. When set to "HIGH", the drill rotates at a high speed.

Low speed Shift knob

Fig. 7

High speed HIGH Shift knob

Fig. 8

CAUTION

- When changing the rotational speed with the shift knob, confirm that the switch is off. Changing the speed while the motor is rotating will damage the gears.

- When setting the shift knob to "HIGH" (high speed) and the position of the clutch dial is between "16" and "22", it may happen that the clutch does not engage and that the motor is locked. In such a case, please set the shift knob to "LOW" (low speed).

- If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery may be burnt.

● To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, if the tool is overloaded, the motor may stop. However, this is not the trouble but the result of protection function. In this case, release the switch of tool and eliminate the causes of overloading.

6. How to select tightening torque and rotational speed

Table 6

Use Clutch dial P		Position	Rotating speed selection (Position of the shift knob)
			LOW (Low speed) HIGH (High speed)
Driving	Machine screw 1	-22	For 1/4" (6 mm) or smaller diameter screws.	For 1/4" (6 mm) or smaller diameter screws.
	Wood screw	1 -	For 5/16" (8 mm) or smaller nominal diameter screws.	For 31/64" (4.8 mm) or smaller nominal diameter screws.
Drilling	Brick	T	For 1/2" (13 mm) or smaller diameters.	For 13/32" (10 mm) or smaller diameters.
	Wood	I	For 1-1/2" (38 mm) or smaller diameters.	For 7/8" (22 mm) or smaller diameters.
	Metal	I	——	For drilling with a metal working drill bit.

CAUTION

● The selection examples shown in Table 6 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 hammer drill with a machine screw at HIGH (high speed), a screw may damage or a bit may lose due to the tightening torque is too strong. Use the hammer drill at LOW (low speed) when using a machine screw.

NOTE

The use of the battery BSL18 series 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.

1. Mounting and dismounting of the bit

(1) After inserting a driver bit, etc. into the keyless drill chuck, firmly 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

Loosen the sleeve by turning it toward the left (in the counter-clockwise direction as viewed from the front).

Loose Sleeve Tighten

CAUTION

When it is no longer possible 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.

1. Confirm that the battery is mounted correctly
2. 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. 10). (The L) and R marks are provided on the selector button.)

CAUTION

Always use this unit with clockwise rotation, when using it as an impact drill.

1. 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.

1. For drilling into brick

Excessive pressing force never increases drilling speed. It will not only damage the drill tip or reduce working efficiency, but could also shorten the service life of drill bit. Operate the hammer drill within 10-15 kg pressing force while drilling into brick.

1. Using the light

Pull the trigger switch to light up the light. The light keeps on lighting while the trigger switch is being pulled. The light goes out after releasing the trigger switch. (Fig. 11).
