I. GENERAL SAFETY

RULES

WARNING! Read all instructions

Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool and battery operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work Area Safety

1)Keep 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 which 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 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 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.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

	Personal Safety
			EN
	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 personal injury.
	2) Use safety equipment. Always wear
		eye protection.
		Safety equipment such as dust mask,
		non-skid safety shoes, hard hat, or
		hearing protection used for appropriate
		conditions will reduce personal injuries.
	3)	Avoid accidental starting. Ensure the
		switch is in the off position before
		plugging in.
		Carrying power tools with your finger on
		the switch or plugging in the 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 jewellery. 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.

Use of these devices 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 it 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
	EN
		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 tools 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 and tool bits etc. in accordance with these instructions and in the manner intended for the particular type of power tool, 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)Ensure the switch is in the off position before inserting battery pack.

Inserting battery pack into power tools that have the switch on invites accidents.

2)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.

3)Use power tools only with specifically designated battery packs.

Use of any other battery packs may create a risk of injury and fire.

4)When 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.

5)Under abusive conditions, liquid may be ejected from battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts 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 power tool is maintained.

II. INTENDED USE

This tool is a Cordless Impact Wrench and can be used to tighten bolts, nuts, and screws. Additionally, it provides a torque control function that automatically stops tool operation when a preset load is reached to deliver consistent tightening torque. Additionally, a separately available Assembly Qualifier can provide wireless monitoring to determine whether tightening has been completed properly.

III. ADDITIONALSAFETY

RULES

1)Wear ear protectors when using the tool for extended periods.

2)Be aware that this tool is always in an operating condition, since it does not have to be plugged into an electrical outlet.

3)Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hid­ den wiring or its own cord.

Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

4)Do NOT operate the Forward/Reverse lever when the main switch is on. The battery will discharge rapidly and damage to the unit may occur.

5)During charging, the charger may become slightly warm. This is normal.

Do NOT charge the battery for a long period.

6)When storing or carrying the tool, set the Forward/Reverse lever to the center position (switch lock).

[Main Unit]

CAUTION:

If a tool holder is used with the Panasonic EYF series assembly tools, make sure the tool’s trigger switch doesn’t hit the tool holder. It may run the tool accidentally and result in battery failure by unexpected battery discharge.

[Fig.17]

	CAUTION:
		EN
	When storing or carrying the tool, set
	the Forward/Reverse lever to the center
	position (switch lock).
	NOTE:
	Exercise caution to ensure no objects
	come into contact with the tool’s trigger
	switch.
	If an object comes into contact with
	the tool’s trigger switch, even while the
	Forward/Reverse lever is in the center
	position (locked), a small amount of
	electric current may continue flowing,
	which may cause an excessive dis-
	charge from the battery pack and sub-
	sequent battery pack failure.

Switch and Forward/Reverse

Lever Operation

[Fig.18]

1.Push the lever for forward or reverse rotation. Check the direction of the lever before using.

2.Depress the trigger switch slightly to start the tool slowly.

3.Speed will increase by pressing the trigger. The tool stops working immediately by releasing the trigger.

4.When done with an application, lock the switch by centering the lever.

NOTE:

The more the speed control trigger is pulled, the higher the speed becomes.

CAUTION:

When operating the tool by pulling the trigger, there may be a momentary lag before rotation starts. This does not signal a malfunction.

*This lag occurs as the tool’s circuitry starts up when the trigger is pulled for the first time after installing a battery pack or after the tool has not been used for at least 1 minute (or at least 5 minutes when the LED is on). Rotation will start without any lag during second and subsequent operations.

CAUTION:

When the tool stops automatically after the switch is released during impactmode tightening and then reengaged within 1 second, the red lamp will light up to indicate the risk of excessive torque application as a result of retightening.

NOTE:

•The tightening confirmation lamp will not turn on under the following conditions:

•When the torque clutch is set to “F”

•During reverse rotation operation

•The lamp turns off when the tool is in operation.

Control Panel

[Fig.19]

(1) The torque control function

The torque control function calculates the load from the motor’s rotational angle during the hammer impact and determines that the bolt has been properly seated when a preset load value is exceeded. Driving is then automatically stopped after a preset number of impacts have been delivered to the bolt.

CAUTION:

•Always check the tool’s tightening torque before use. The required adjustment is dependent on the type of threaded connection and can be best determined by practical trials. Check the trial screwings with a torque wrench. Improper tool operation may result in excessive or inadequate tightening.

•Always operate the tool with the switch fully depressed. The torque control function will not operate when the switch is not sufficiently depressed, preventing the tool from stopping automatically.

•In work where a heavy load comes to bear during tightening, the load may be interpreted as the seating of the bolt, preventing the bolt from being completely tightened.

•Repeated tightening of the same bolt may break the bolt or deform the material into which the bolt is being driven as a result of excessive tightening.

•The tightening torque value and precision vary with factors such as the material into which the bolt is being driven and the condition of the socket being used. Adjust the torque as necessary for the work being performed. Bolt tightening torque varies due to the factors described below.

1)Bolt

•Bolt diameter: Tightening torque generally increases with bolt diameter.

•Torque coefficient (indicated by the bolt manufacturer), grade, length, etc.

2)Other

•Bit and socket condition: Material, amount of play, etc.

•Use of a universal joint or socket adapter

•User: Manner in which the tool is applied to the bolt, strength with which the tool is held, manner in which the tool’s switch is depressed

•Condition of object being tightened: Ma-terial, seating surface finish

(2)The battery indication lamp

•Use the battery indication lamp to check how much power is left in the battery.

•Battery life varies slightly with ambient temperature and battery characteristics. The lamp is designed to provide a rough indication of remaining battery life.
