Battery protection system

Lithium-ion battery with star marking

Fig.2: 1. Star marking

Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life.
The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

Overloaded:
The tool is operated in a manner that causes it to draw an abnormally high current.
In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart.
If the tool does not start, the battery is overheated. In this situation, let the battery cool before turning the tool on again.

Low battery voltage:
The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Indicating the remaining battery capacity

Only for battery cartridges with “B” at the end of the model number

Fig.3: 1. Indicator lamps 2. Check button

Press the check button on the battery cartridge to indi-cate the remaining battery capacity. The indicator lamps light up for few seconds.

NOTE: Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

Switch action

Fig.4: 1. Switch trigger

CAUTION: Before installing the battery car-tridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop.

Lighting up the front lamp

Fig.5: 1. Lamp

CAUTION: Do not look in the light or see the source of light directly.

Pull the switch trigger to light up the lamp. The lamp keeps on lighting while the switch trigger is being pulled. The lamp goes out 10 -15 seconds after releasing the trigger.

NOTE: Use a dry cloth to wipe the dirt off the lens of the lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination.

Reversing switch action

Fig.6: 1. Reversing switch lever

CAUTION: Always check the direction of rotation before operation.
CAUTION: Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may dam-age the tool.
CAUTION: When not operating the tool, always set the reversing switch lever to the neu-tral position.

This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for coun-terclockwise rotation.
When the reversing switch lever is in the neutral posi-tion, the switch trigger cannot be pulled.

Speed change

CAUTION: Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever positioned halfway between the “1” side and “2” side, the tool may be damaged.
CAUTION: Do not use the speed change lever while the tool is running. The tool may be damaged.

Position of speed change lever| Speed| Torque| Applicable

operation

---|---|---|---
1| Low| High| Heavy load- ing operation
2| High| Low| Light loading operation

To change the speed, switch off the tool first. Select the “2” side for high speed or “1” for low speed but high torque. Be sure that the speed change lever is set to the correct position before operation.
If the tool speed is coming down extremely during the operation with “2”, slide the lever to the “1” and restart the operation.

Adjusting the fastening torque

Fig.8: 1. Adjusting ring 2. Graduation 3. Arrow

The fastening torque can be adjusted in 22 steps by turning the adjusting ring. Align the graduations with the arrow on the tool body. You can get the minimum fastening torque at 1 and maximum torque at marking.
The clutch will slip at various torque levels when set at the number 1 to 21. The clutch does not work at
the marking.
Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application.
The following shows the rough guide of the relationship between the screw size and graduation.

Graduation| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| 11| 12| 13| 14| 15| 16| 17| 18| 19| 20| 21

The hook is convenient for temporarily hanging the tool. This can be installed on either side of the tool. To install the hook, insert it into a groove in the tool housing on either side and then secure it with a screw. To remove, loosen the screw and then take it out.

Installing driver bit holder

Optional accessory

Fig.11: 1. Driver bit holder 2. Driver bit

Fit the driver bit holder into the protrusion at the tool foot on either right or left side and secure it with a screw. When not using the driver bit, keep it in the driver bit holders. Driver bits 45 mm-long can be kept there.

OPERATION

CAUTION: Always insert the battery cartridge all the way until it locks in place. If you can see the red indicator on the upper side of the button, it is not locked completely. Insert it fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
CAUTION: When the speed comes down extremely, reduce the load or stop the tool to avoid the tool damage.

Hold the tool firmly with one hand on the grip and the other hand on the bottom of the battery cartridge to control the twisting action.
Fig.12

Screwdriving operation

CAUTION: Adjust the adjusting ring to the proper torque level for your work.
CAUTION: Make sure that the driver bit is inserted straight in the screw head, or the screw and/or driver bit may be damaged.

Place the point of the driver bit in the screw head and apply pressure to the tool. Start the tool slowly and then increase the speed gradually. Release the switch trigger as soon as the clutch cuts in.

NOTE: When driving wood screw, pre-drill a pilot hole 2/3 the diameter of the screw. It makes driving easier and prevents splitting of the workpiece.

Drilling operation

First, turn the adjusting ring so that the pointer points to the marking. Then proceed as follows.

Drilling in wood
When drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the drill bit into the workpiece.

Drilling in metal
To prevent the drill bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. Place the point of the drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-tions are iron and brass which should be drilled dry.

• CAUTION: Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your drill bit, decrease the tool performance and shorten the service life of the tool.
• CAUTION: Hold the tool firmly and exert care when the drill bit begins to break through the workpiece. There is a tremendous force exerted on the tool/drill bit at the time of hole break through.
• CAUTION: A stuck drill bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly.
• CAUTION: Always secure small workpieces in a vise or similar hold-down device.
• CAUTION: If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
