SAFETY WARNINGS

General power tool safety warnings

WARNING : Read all safety warnings and all instructions. Failure to follow the warnings and instruc­tions may result in electric shock, fire, and/or serious injury.

Save all warnings and instruc­tions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

1. Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmo­spheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of elec­tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con­ditions. Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a ground fault circuit inter­rupter (GFCI) protected supply. The use of a GFCI reduces the risk of electric shock.

Personal Safety

1. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or med­ication. A moment of inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewel­lery, or long hair can be caught in moving parts.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.

Power tool use and care

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
2. Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such pre­ventive safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of chil­dren and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories tool bits, etc by these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

Battery tool use and care

1. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
2. Use power tools only with specifically desig­nated battery packs. Use of any other battery packs may create a risk of injury and fire.
3. When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery termi­nals together may cause burns or a fire.
4. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If con­tact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

Service

1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
2. Follow instructions for lubricating and chang­ing accessories.
3. Keep handles dry, clean, and free from oil and grease.

Cordless driver drill safety warnings

1. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
2. Hold the power tool by insulated gripping sur­faces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
3. Hold the power tool by insulated gripping sur­faces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
4. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.
5. Hold the tool firmly.
6. Keep hands away from rotating parts.
7. Do not leave the tool running. Operate the tool only when hand-held.
8. Do not touch the drill bit or the workpiece immediately after the operation; they may be extremely hot and could burn your skin.
9. Some materials contain chemicals that may be toxic. Take caution to prevent dust inhala­tion and skin contact. Follow material supplier safety data.

FUNCTIONAL DESCRIPTION

CAUTION :  Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking the function of the tool.

Installing or removing the battery cartridge

CAUTION : Always switch off the tool before installing or removing of the battery cartridge.

CAUTION : Hold the tool and the battery car­tridge firmly when installing or removing the battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury.

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge. To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

CAUTION: Always install the battery cartridge fully. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

CAUTION: Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.

Indicating the remaining battery capacity

Press the check button on the battery cartridge to indi­cate the remaining battery capacity. The indicator lamps light up for a few seconds.

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

Tool/battery protection system
The tool is equipped with a tool/battery protection sys­tem. This system automatically cuts off power to the motor to extend tool and battery life. The tool will auto­matically stop during operation if the tool or battery is placed under one of the following conditions:

Overload protection
When the tool/battery is operated in a manner that causes it to draw an abnormally high current, the tool automat­ically stops without any indication. 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.

Overheat protection
When the tool/battery is overheated, the tool stops automatically. In this situation, let the tool/battery cool before turning the tool on again.

Overdischarge protection
When the battery capacity is not enough. the tool stops automatically. In this case. remove the battery from the tool and charge the battery.

Switch action

CAUTION : Before installing the battery car­tridge 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

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 approximately 10 seconds after releasing the switch trigger.

Reversing switch action

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 dam­age the tool.

CAUTION: When not operating the tool, always set the reversing switch lever to the neu­tral 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 coun­terclockwise rotation. When the reversing switch lever is in the neutral posi­tion, 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.

To change the speed, switch off the tool first. Push the speed change lever to display “2” 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 display “2”, push the lever to display “1” and restart the operation.

Adjusting the fastening torque

The fastening torque can be adjusted in 19 levels 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 18 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.

ASSEMBLY

CAUTION : Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing or removing driver bit/ drill bit

Turn the sleeve counterclockwise to open the chuck jaws. Place the driver bit/drill bit in the chuck as far as it will go. Turn the sleeve clockwise to tighten the chuck. To remove the driver bit/drill bit, turn the sleeve counterclockwise.

Installing hook

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.

OPERATION

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 batter/ cartridge to control the twisting action.

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 the splitting of the workpiece.

Drilling operation
First, turn the adjusting ring so that the arrow 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 excep­tions are iron and brass which should be drilled dry.

CAUTION : Pressing excessively on the tool will not speed up the dril ling. This excessive pressure will only serve to damage the tip of your drill bit, decrease the tool’s 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 breakthrough.

CAUTION : A stuck drill bit can be removed simply by setting the reversing switch to reverse rotation to back out. However, the tool may back out abruptly if you do not hold it firmly.

CAUTION: Always secure workpieces in a vise or similar hold-down device.

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, benzene, thinner, alcohol, or the like. Discoloration, deformation, or cracks may result.

OPTIONAL ACCESSORIES

CAUTION : These accessories or attachments are recommended for use with the tool specified in this manual. The use of any other accessories or attachments might present a risk of injury to persons. Only use accessory or attachment for its stated purpose.
