Supporting the battery charger with hand, pull out the battery from the battery charger.

NOTE

Be sure to pull out the battery from the battery 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

• 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 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 installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

1. Tightening mode selector function (Fig. 14)

CAUTION

• Do not subject the switch panel to shock or damage.
• Select tightening mode while the trigger switch is released. Failure to do so could result in malfunction.

(1) Tightening mode selector switch

By using the Tightening mode selector switch, the tightening torque can be adjusted according to the type of work.

The Tightening mode switches between 5 different modes each time the Tightening mode selector switch is pressed.

Upon pulling the trigger switch in bolt single mode, the driver will automatically stop after applying a number of impacts.

Soft / power / bolt and self drilling screw mode will commence impact upon pulling the trigger switch and will continuously apply impact without auto-stopping.

Soft mode is a mode that does not inflict damage on thin nails or decorative materials.

Power mode can be used for normal work up to heavy load work.

Bolt mode has a short pull margin for the trigger switch, making the driver ideal for high-speed tightening work.

Bolt single mode controls the impact, allowing control of the tightening force. Use this mode for delicate work such as tightening bolts for racks, fences, furniture, etc.

Self drilling screw mode is ideal for tightening self drilling screws by reducing the chances of overtightening that could result in severing the screw head, breaking the screw, or slippage.

	Lighting Lighting Lighting Blinking Lighting

NOTE

○ The appropriate mode differs depending on the screw and the material being screwed. Drive in a few test screws and adjust the mode setting accordingly.

☐ The tightening mode selector switch can only be set after the battery has been installed in the driver and the trigger switch has been pulled once.

1. Tightening and loosening screws Install the bit that matches the screw, line up the bit in the grooves of the head of the screw, then tighten it. Push the impact driver just enough to keep the bit fitting the head of the screw.

CAUTION

• Applying the impact driver for too long tightens the screw too much and can break it.
  ● Tightening a screw with the impact driver at an angle to that screw can damage the head of the screw and the proper force will not be transmitted to the screw. Tighten with this impact driver lined up straight with the screw.

• Tightening and loosening bolts

A hex. socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex. socket. Holding the tool in line with the bolt, press the power switch to impact the nut for several seconds.

If the nut is only loosely fitted to the bolt, the bolt may turn with the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually tighten the bolt and nut to prevent them slipping.

12. LED light warning signal (Fig. 15)

This product features functions that are designed to protect the tool itself as well as the battery. While the switch is pulled, if any of the safeguard functions are triggered during operation, the LED light will blink as described in Table 7. When any of the safeguard functions are triggered, immediately remove your fi nger from the switch and follow the instructions described under corrective action.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work

After use for continuous bolt-tightening work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.

CAUTION

Do not touch the metal parts, as it gets very hot during continuous work.

2. Cautions on use of the speed control switch

This switch has a built-in, electronic circuit which steplessly varies the rotation speed. Consequently, when the trigger switch is pulled only slightly (low speed rotation) and the motor is stopped while continuously driving in screws, the components of the electronic circuit parts may overheat and be damaged.

3. Use a tightening time suitable for the screw

The optimum torque for a screw differs according to the material and size of the screw, and the material being screwed etc., so please use a tightening time suitable for the screw. In particular, if a long tightening time is used in the case of screws smaller than 5/16" (M8), there is a danger of the screw breaking, so please confirm the tightening time and the tightening torque beforehand.

4. Work at a tightening torque suitable for the bolt under impact

The optimum tightening torque for nuts or bolts differs with material and size of the nuts or bolts. An excessively large tightening torque for a small bolt may stretch or break the bolt. The tightening torque increases in proportion to the operation time. Use the correct operating time for the bolt.

5. Holding the tool

Hold the tool firmly with both hands. In this case hold the tool in line with the screw or bolt.

It is not necessary to push the tool very hard. Hold the tool with a force just sufficient to counteract the impact force.

6. Confir rm the tightening torque

The following factors contribute to a reduction of the tightening torque. So confi rm the actual tightening torque needed by screwing up some bolts before the job with a hand torque wrench. Factors affecting the tightening torque are as follows.

(1) Voltage

When the discharge margin is reached, voltage decreases and tightening torque is lowered.

(2) Operating time

The tightening torque increases when the operating time increases. But the tightening torque does not increase above a certain value even if the tool is driven for a long time.

(3) Diameter of bolt

The tightening torque differs with the diameter of the bolt. Generally a larger diameter bolt requires larger tightening torque.

(4) Tightening conditions

The tightening torque differs according to the torque ratio; class, and length of bolts even when bolts with the same size threads are used. The tightening torque also differs according to the condition of the surface of workpiece through which the bolts are to be tightened. When the bolt and nut turn together, torque is greatly reduced.

(5) Tightening torque varies, depending on the battery's charge level.

MAINTENANCE AND INSPECTION

⚠️ CAUTION: Pull out battery before doing any inspection or maintenance.

1. Checking the condition of the bit

The bits should be checked regularly broken bits can slip or decrease the efficiency of the motor and burn it out.

Replace worn bits with new ones.

CAUTION

If you use a driver bit of which point is worn or broken, it will be dangerous since it slips. So replace it with a new one.

1. Check the Screws

Loose screws are dangerous. Regularly inspect them and make sure they are tight.

CAUTION

Using this power tool with loosened, screws is extremely dangerous.

1. 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.

1. Check for Dust

Dust may be removed with a soft cloth or a cloth dampened with soapy water.

Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.

1. 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.

CAUTION

Remove any swarf or dust which may have collected on the terminals.

Failure to do so may result in malfunction.

1. Disposal of the exhausted battery
