Frequently Asked Questions - ASW 1845 PC Fein

How to change the direction of rotation?

Only operate the rotation direction switch when the motor is at a complete standstill. Set it to the middle position to avoid accidental activation.

What does the steady green LED display mean?

The green LED illuminated (1 second) indicates that the screw was driven correctly, the shut-off criterion (e.g., torque) has been met.

What to do if the red LED flashes 2 times per second?

This indicates overheating of the power tool. Allow it to cool down; once cooled, it can be used again. If the issue recurs, have it checked by the after-sales service.

How to adjust the screw torque?

Before first use, set the torque of the mechanical cut-off clutch to the desired value and check using a dynamic measurement system.

Can I use batteries from other brands?

No, only use intact original FEIN batteries designed for your power tool. Using inappropriate batteries may cause fire or explosion.

How to clean the screwdriver?

Clean the ventilation openings regularly with non-metal tools. Use dry, oil-free compressed air to blow out the interior through the ventilation slots.

What to do if the machine does not start?

First check the battery charge status. If the battery is discharged, charge it. If the problem persists, remove the battery and reinsert it. If the red LED flashes, refer to the LED display table.

How to replace a bit or socket?

You can replace bits, sockets, battery, and accessories yourself. Ensure the tool is stopped and the battery removed before any operation.

Where to find spare parts?

The updated spare parts list is available at www.fein.com. Use only original spare parts.

What is the temperature range for battery use?

WARNING

Read all safety warnings and all instructions. Failure to follow the

warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

Do not use this power tool before you have thoroughly read and completely understood this Instruction Manual and the enclosed "General

Safety Instructions" (document number 3 41 30 465 06 0). The documents mentioned should be kept for later use and enclosed with the power tool, should it be passed on or sold.

Please also observe the relevant national industrial safety regulations.

Intended use of the power tool:

Hand-held screwdriver for screwing in and unscrewing screws and nuts in weather-protected environments without water supply using the application tools and accessories recommended by FEIN.

Special safety instructions.

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.

Beware of any concealed electric cables, gas or water conduits. Check the working area before commencing work, e. g. with a metal detector.

Secure the work piece firmly. A work piece that is gripped tightly in a clamping device or vice, is more secure than if held by hand.

Hold the power tool firmly. High reaction torque can briefly occur.

Do not work with materials containing magnesium. Danger of fire.

Do not work with CFRP (carbon-fiber-reinforced polymer) and materials containing asbestos. These materials are considered carcinogenic.

Do not rivet or screw any name-plates or signs onto the power tool. If the insulation is damaged, protection against an electric shock will be ineffective. Adhesive labels are recommended.

Do not use accessories which are not specifically designed and recommended by the power tool manufacturer. Safe operation is not ensured merely because an accessory fits your power tool.

Clean the ventilation openings on the power tool at regular intervals using non-metal tools. The blower of the motor draws dust into the housing. An excessive accumulation of metallic dust can cause an electrical hazard.

Never look or stare into the light of the power tool's lamp from a short distance. Never point the light of the lamp into the eyes of other persons in close vicinity.

The radiation produced by the lamp can be harmful for the eye.

Do not direct the power tool against yourself, other persons or animals. Danger of injury from sharp or hot application tools.

Use and handling of the battery (battery pack).

To avoid hazardous situations such as burns, fire, explosion, skin injuries, and other injuries when handling the battery, observe the following instructions:

Batteries must not be disassembled, opened or reduced in size. Do not subject batteries to mechanical impact or shock. Hazardous vapours and fluid can escape in case of damage and improper use of the battery. The vapours can irritate the respiratory system. Liquid ejected from the battery may cause skin irritations or burns.

When battery fluid from a damaged battery has come into contact with objects close by, check the respective components, clean them or replace them as required.

Keep the battery away from heat and fire. Do not store the battery in direct sunlight.

Do not remove the battery from its original packaging until it is going to be used.

Before any work on the machine itself, remove the battery from the power tool. If the power tool accidentally starts, there is danger of injury.

Mount the battery only when the power tool is switched off.

Remove the battery only when the power tool is switched off.

Keep the battery away from children.

Keep the battery clean and protect it against moisture and water. Clean contaminated battery terminals and power tool connections with a dry, clean cloth.

Use only intact original FEIN batteries that are intended for your power tool. When working with and charging incorrect, damaged, repaired or reconditioned batteries, imitations or other brands, there is danger of fire and/or explosion.

Follow the safety warnings in the operating instructions of the battery charger.

Hand/arm vibrations

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.

Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Operating Instructions.

The power tool is not preset by the manufacturer for the intended application case.

Before putting the power tool into operation for the first time, the torque of the mechanical shut-off clutch must be set to the desired value within the permissible test range and checked using a suitable dynamic measuring system.

In the factory setting, the configuration of the machine parameters corresponds to the homologation state (machine-specific homologations can be found on the FEIN website).

Through individual configuration of the machine parametrisation using FEIN ParameterControl software, the operating behavior of the machine can change.

The power tool has a “MultiVolt” battery interface, which allows for operation with different battery types. Depending on the type of battery used, the operating behaviour of the machine can change.

Before starting operation, compliance with the required process parameters must always be checked individually for the respective application under consideration of real operating conditions.

Regular control of the operating behaviour as well as compliance with the required process parameters shall be carried out to an appropriate extent.

The power tool is equipped with a soft-starting feature. If the motor switches off after a proper screwdriving operation, restarting is not possible until after 0.8 seconds. This prevents accidental retightening of already tightened screws.

In left-hand running mode, the power tool switches off with significantly increased torque.

During operation, pay attention to optical and acoustic signals of the power tool as described in the section "Meaning of the LED indicators and the beeps of the power tool".

Handling the battery.

Store, operate and charge the battery only using FEIN battery chargers within the battery operating-temperature range between 5°C – 45 °C

(41 °F – 113 °F). At the beginning of the charging procedure, the battery temperature must be within the battery operating-temperature range.

LED indicator	Meaning Activity
1 – 4 green LED	Percentage of charge condition	Operation
Continuous red light	Battery is almost empty	Charge battery
Red flashing light	Battery is not ready for operation	Bring the battery into the battery operating-temperature range, then charge

The real percentage of the battery charge condition is only indicated when the power tool motor is stopped. The electronics automatically switch off the motor prior to the battery being deep discharged.

Selecting the Rotation Direction (see page 16/17).

Adjust the rotation selector switch only when the machine is at a complete stop.

To avoid accidental starting, e. g., during transport, set the rotation selector switch to the centre position.

Use of straight output (ASW18-6/12-PC)

Before using the power tool, make sure that the maximum torque of 8 Nm is not exceeded.

Shut-off procedure of the machine

The power tool switches off approx. 30 min after the last switch actuation, meaning, the power tool can only be reactivated again by switching on.

Meaning of the LED indicators and the beeps of the power tool.

The following conditions apply as factory-set. Further indication options are possible via Parameter Control (see PC software).

LED indicator Meaning Explanation
√X	Green LED indicator lights up (for 1 second).	The screwdriving operation has been carried out properly. The preset switch-off criteria (e. g. the torque) has been reached.
√X	The red LED indicator lights up (for 1 sec-ond) and a short beep sounds.	The screwdriving operation has not been carried out properly. The required switch-off criteria (e. g. the torque) has not been reached. Alternatively, a pre-set error criterion (e. g. too large rotation angle) has been reached.
	Yellow LED indicator lights up continuously.	The remaining battery capacity is less than 25 %. The battery must be replaced of the battery in the near future.
√X	The red LED indicator flashes (1 time per second) and the yellow LED indicator lights up continuously.	The battery is discharged and must be replaced.
√X	Red LED indicator lights up permanently. The	machine has an irreversible error. The machine must be repaired by the after-sales serv-ice.

Parameter assignment

Differing to the existing standard programs, the AccuTec screwdrivers can be freely programmed in some ranges. To realise these special solutions, an additional PC program is required for assignment of the parameters. Afterwards, the data can be transferred to the screwdriver with the programming adapter. The current software can be downloaded from FEIN via the Internet under www.fein.com. It can be found in the country-specific AccuTec sector. A link to this section is provided on the included USB card of the separately available programming adapter.

We recommend that you keep the firmware on your AccuTec screwdrivers up-to-date.

Repair and customer service.

When working metal under extreme operating conditions, it is possible for conductive dust to settle in the interior of the power

tool. Blow out the interior of the power tool via the ventilation slots frequently with dry and oil-free compressed air.

Regularly check the condition of the power tool and arrange for necessary maintenance or repair work in good time.

The service life of the machine, battery and accessories (e.g. angle head and application tool) depends on the load and application of the machine.

Products that have come into contact with asbestos may not be sent in for repair. Dispose of products contaminated with asbestos according to the applicable country-specific regulations for such disposal.
