SAFETY WARNINGS General power tool safety warnings

Read all safety warnings, instruc- tions, illustrations and specications provided with this power tool. Failure to follow all instructions listed below mayresultinelectricshock,reand/orseriousinjury. Save all warnings and instruc- tions for future reference. Theterm"powertool"inthewarningsreferstoyour mains-operated(corded)powertoolorbattery-operated (cordless)powertool. Cordless impact wrench safety warnings

1. Hold the power tool by insulated gripping

surfaces, when performing an operation where the fastener may contact hidden wiring. Fastenerscontactinga"live"wiremaymake exposedmetalpartsofthepowertool"live"and could give the operator an electric shock.

2. Wear ear protectors.

3. Check the impact socket carefully for wear,

cracks or damage before installation.

4. Hold the tool rmly.

5. Keep hands away from rotating parts.

6. Always be sure you have a rm footing.

Be sure no one is below when using the tool in high locations.

7. The proper fastening torque may differ

depending upon the kind or size of the bolt. Check the torque with a torque wrench. SAVE THESE INSTRUCTIONS.

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. Important safety instructions for battery cartridge

Before using battery cartridge, read all instruc- tions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery.

2. Do not disassemble battery cartridge.

3. If operating time has become excessively

shorter, stop operating immediately. It may result in a risk of overheating, possible burns and even an explosion.

If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. It may result in loss of your eyesight.

5. Do not short the battery cartridge:

(1) Do not touch the terminals with any con- ductive material. (2) Avoid storing battery cartridge in a con- tainer with other metal objects such as nails, coins, etc. (3) Do not expose battery cartridge to water or rain. A battery short can cause a large current ow, overheating, possible burns and even a breakdown.

6. Do not store the tool and battery cartridge in

locations where the temperature may reach or exceed 50 °C (122 °F).

7. Do not incinerate the battery cartridge even if

it is severely damaged or is completely worn out. The battery cartridge can explode in a re.

8. Be careful not to drop or strike battery.

9. Do not use a damaged battery.

The contained lithium-ion batteries are subject to the Dangerous Goods Legislation requirements.

Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely

discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.

2. Never recharge a fully charged battery car-

tridge. Overcharging shortens the battery service life.

3. Charge the battery cartridge with room tem-

perature at 10 °C - 40 °C (50 °F - 104 °F). Let a hot battery cartridge cool down before charging it.

4. Charge the battery cartridge if you do not use

it for a long period (more than six months).6 ENGLISH FUNCTIONAL DESCRIPTION CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Installing or removing battery cartridge CAUTION: Always switch off the tool before installing or removing of the battery cartridge.

Reversing switch action ►Fig.8: 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 directionofrotationbeforethetoolstopsmaydam- 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.8 ENGLISH Changing the impact force/mode ►Fig.9: 1. Changed in four steps 2. Hard impact mode 3. Medium impact mode 4. Soft impact mode 5. Reverse rotation auto stop mode

You can change the impact mode in four steps: hard, medium, soft, and reverse rotation auto stop mode. To select the step, press the button

Forapproximatelyoneminuteafterreleasingtheswitch trigger, the impact force can be changed. Hard, Medium, and Soft impact mode allows a tighten- ing suitable to the work. The function of reverse rotation auto stop mode works onlywithpullingthetriggerfullyincounterclockwisetool rotation. When the bolt/nut gets enough loosened, the tool stops the impact and rotation.

For impact socket with O-ring and pin ►Fig.11: 1. Impact socket 2. O-ring 3. Pin Move the O-ring out of the groove in the impact socket and remove the pin from the impact socket. Fit the impact socket onto the square drive so that the hole in the impact socket is aligned with the hole in the square drive. Insert the pin through the hole in the impact socket and square drive. Then return the O-ring to the original posi- tion in the impact socket groove to retain the pin. To remove the impact socket, follow the installation procedures in reverse.9 ENGLISH Tool with the detent pin ►Fig.12: 1. Impact socket 2. Hole 3. Square drive

5. The manner of holding the tool or the material

of driving position to be fastened will affect the torque.

6. Operating the tool at low speed will cause a reduc-

tion in the fastening torque. 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.
