General Power Tool Safety Warnings

• 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.

• 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.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• Use the power tool, accessories and tool bits etc. in accordance with 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

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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.
• Under abusive conditions, liquid may be ejected from the 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

• 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.

Safety Warnings for Screwdriver

• Hold 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.
• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
• Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
• Do not open the battery. Danger of short-circuiting.
•  Protect the battery against heat, e. g., against continuous
• In case of damage and improper use of the battery, vapours may be emitted. Ventilate the area and seek medical help in case of complaints. The vapours can irritate the respiratory system.
• Use the battery only in conjunction with your power tool. This measure alone protects the battery against dangerous overload.
• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit can occur and the battery can burn, smoke, explode or overheat.

Note: about battery charging:

• The battery should be charged at ambient temperatures between 1 O and 40°C {ideally around 20’C)
• After charging, allow 15 minutes for the battery to cool before use
• Ensure that the charger is disconnected from the mains supply after use, and is stored correctly
• DO NOT leave batteries on charge for extended periods and NEVER store batteries on charge
• The Battery Charger monitors battery temperature and voltage while charging. Remove the
• Battery once charging is complete to maximise charge cycles of the battery and not waste power
• Batteries can become faulty over time, individual cells in the battery can fail and the battery could short. The charger will not charge faulty batteries. Use another battery, if possible, to check correct functionality of the charger and purchase a replacement battery if a faulty battery is indicated
• DO NOT store lithium-ion battery packs in a discharged state over a long period as this can damage the lithium-ion cells. For long-term storage, store batteries in a high charge state disconnected from the power tool.
• The capacity of batteries will reduce over time. After 100 charge cycles, the battery’s operation time and the maximum torque performance of the driver will slightly reduce. This decline will continue until the battery has minimal capacity after 250 charge cycles. This is normal and not a fault with the battery pack.

Removing the battery

The battery is equipped with two locking levels that should prevent the battery from falling out when pushing the battery unlocking button unintentionally. As long as the battery is inserted in the power tool, it is held in position by means of a spring. To remove the battery, press the unlocking button and pull out the battery toward the front. Do not exert any force.
Changing the Tool (see figure A}

• Before any work on the machine itself (e. g. maintenance, tool change, etc.) as well as during transport and storage, remove the battery from the power.There is danger of injury when unintentionally actuating the On/Off switch.
• Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumu­lation of powdered metal may cause electrical hazards.
• When working with an application tool, pay attention that the application tool is connected securely on the tool holder. When the application tool is not securely connected with the tool holder, it can come off during application.

Slide the application tool 9 onto the square drive of the tool holder 1.With this system, there will be a slight amount of play around the application tool 9 after connecting securely to the tool holder 1; this has no influence on the function/safety.

Operation

Method of Operation
The tool holder 1 with the tool is driven by an electric motor via a gear and impact mechanism.
The working procedure is divided into two phases:

Screwing in and tightening (impact mechanism in action).The impact mechanism is activated as soon as the screwed connection runs tight and thus load is put on the motor. In this instance, the impact mechanism converts the power of the motor to steady rotary impacts. When loosening screws or nuts, the process is reversed.

Starting Operation

Inserting the battery
Set the rotational direction switch 6 to the centre position to protect the power tool against accidental starting.
Insert the charged battery 3 from the front into the base of the power tool until the battery is securely locked.
Reversing the rotational direction(see figure B)

The rotational direction switch 6 is used to reverse the rotational direction of the machine. However, this is not possible with the On/Off switch 7 actuated.
Right rotation: For driving in screws and tightening nuts, press the rotational direction switch 6 through to the left stop.
Left Rotation: For loosening and unscrewing screws and nuts, press the rotational direction switch 6 through to the right stop.

Switching On and Off
To start the machine, press the On/Off switch 7 and keep it pressed.
To switch off the machine, release the On/Off switch 7.

Adjusting the Speed
The speed of the switched-on power tool can be variably adjusted, depending on how far the On/Off switch 9 is pressed. Light pressure on the On/Off switch 9 results in a low rotational speed. Further pressure on the switch results in an increase in speed.

Working Advice

Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off.
The torque depends on the impact duration. The maximum achieved torque results from the sum of all individual torques achieved through impact. The maximum torque is achieved after an impact duration of 6-10 seconds. After this duration, the tightening torque is increased only minimally.

Screw Applications with Hard, Spring-loaded or Soft Seat
A test in which the achieved torques in an impact series are measured and transferred to a diagram will produce the curve  of a torque characteristic. The height Of the curve corresponds with the maximum reachable torque, and the steepness indicates the duration in which this is achieved.
A torque gradient depends on the following factors:

Strength properties of the screws/nuts
Type of backing (washer, disc spring, seal)
Strength properties Of the material being screwed/bolted together
Lubrication conditions at the screw/bolt connection

The following application cases result accordingly:

A hard seat is given for metal-to-metal screw applications with the use Of washers. After a relatively short impact duration, the maximum torque is reached (steep characteristic curve). Unnecessary long impact duration only causes  damage to the machine.
A spring-loaded seat is given for metal-to-metal screw applications, however with the use Of spring washers, disc springs, studs or screws/nuts with conical seat as well as when using extensions.
A soft seat is given for screw applications, e. g., metal on wood or when using lead washers or fibre washers as backing.

For a spring-loaded seat as well as for a soft seat, the maximum tightening torque is lower than for a hard seat. Also, a clearly longer impact duration is required.

Tips
Before screwing larger, longer screws into hard materials, it is advisable to predrill a pilot hole with the core diameter Of the thread to approx. 213 of the screw length.
Note: Pay attention that no metal particles enter the power tool.
Belt Clip
With the belt clip 2, the machine can be hung onto a belt. The user has both hands free and the machine is always at hand.Recommendations for Optimal Handling Of the Battery Protect the battery against moisture and water. Store the battery only within a temperature range between —10 oc and 50 ‘C. As an example, do not leave the battery in the car in summer.
Occasionally clean the venting slots of the battery using a soft, clean and dry brush.
A significantly reduced working period after charging indicates that the battery is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

• Before any work on the machine itself (e. g. maintenance, tool change, etc.) as well as during transport and storage, remove the battery from the power tool. There is danger Of injury when unintentionally actuating the On/Off switch.
