GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 mainsoperated (corded) power tool or battery-operated (cordless) power tool

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

2. Electrical safety
   a) 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 risk of electric shock.
   b) 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.
   c) Do not expose power tools to rain or wet conditions.
   Water entering a power tool will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
   Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
   Use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3. Personal safety
   a) 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.

CHARGING

Before using the power tool, charge the battery as follows.

1. Connect the charger’s power cord to the receptacle. When connecting the plug of the charger to a receptacle, the charge indicator lamp will blink in red (At 1- second intervals).

2. Insert the battery into the charger. Firmly insert the battery into the charger as shown in Fig. 3 .

3. Charging
   When inserting a battery in the charger, the charge indicator lamp will blink in blue. When the battery becomes fully recharged, the charge indicator lamp will light up in green. (See Table 1)

4. Charge indicator lamp indication The indications of the charge indicator lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery
   

5. Regarding the temperatures and charging time of the rechargeable battery The temperatures and charging time will become as shown in Table 2.
   
   NOTE The recharging time may vary according to the ambient temperature and power source voltage.

6. Disconnect the charger’s power cord from the receptacle.

7. Hold the charger firmly and pull out the battery.
   NOTE Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc

As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2–3 times

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

• 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 charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, first let the battery cool, then start charging.
• When the charge indicator lamp flickers (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 confirm that the battery being charged with UC18YSL3 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.

MOUNTING AND OPERATION

1. Installing a socket
2. Align the square portions of the socket and the anvil with each other.
3. Make sure to firmly install the socket by pushing it all the way into the anvil.
4. When removing the socket, pull it out of the anvil.
5. Tightening mode selector function
6. High / Low mode selector switch (Fig. 10-a) The tightening mode switches between 4 different rotation speeds each time the High / Low mode selector switch is pressed.
7. Auto stop mode selector switch (Fig. 10-b) Each time the auto stop mode selector switch is pressed, the auto stop function will switch between ON and OFF.
   When auto stop is OFF (auto stop mode indicator lamp is OFF): When the trigger switch is pulled, the power tool will continue to apply impact. (Will not auto stop)
   When auto stop is ON (auto stop mode indicator lamp is ON): When the trigger switch is pulled, the power tool will apply impact for a preset amount of time and then auto stop.

MAINTENANCE AND INSPECTION

1. Inspecting the socket
   A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of a socket holes periodically, and replace with a new one if needed.

2. Inspecting the mounting screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Maintenance of the motor
   The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

4. Inspection of terminals (tool and battery) Check to make sure that swarf and dust have not collected on the terminals.
   On occasion check prior, during and after operation.
   On occasion check prior, during and after operation.
   CAUTION
   Remove any swarf or dust which may have collected on the terminals. Failure to do so may result in malfunction.

5. Cleaning on the outside
   When the tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

6. Storage
   Store the power tool and battery in a place in which the temperature is less than 40°C and out of reach of children.

NOTE
Storing lithium-ion batteries. Make sure the lithium-ion batteries have been fully charged before storing them. Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, significantly reducing battery usage time or rendering the batteries incapable of holding a charge. However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times. If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
