Frequently Asked Questions - WL 380 4K5

How to turn the WL 380 flashlight on and off?

Press the control button to turn on the flashlight. A short press changes the lighting level. To turn off, hold the button until it turns off.

How to switch between Flood and Spot modes?

Hold the control button for about one second to switch from Flood mode (wide beam) to Spot mode (focused beam), and vice versa.

How to charge the flashlight?

Use the provided USB-C cable (or a standard USB-C cable) and a power adapter. Plug the cable into the flashlight's USB-C port and into a power source. Full charging takes about 4 hours. The indicator light flashes during charging and turns off or stays solid when complete.

Can I use the flashlight while it is charging?

Yes, the battery can be charged while using the flashlight.

What is the battery life?

Battery life depends on the chosen mode: in Flood Low (12 lm): approximately 102 h, Flood Medium (160 lm): 10 h, Flood High (380 lm): 6 h. In Spot Low (60 lm): 35 h, Spot High (280 lm): 7 h.

Is the flashlight waterproof?

Yes, it has an IPX5 protection rating, meaning it is resistant to water jets. It is not designed for submersion.

How to attach the flashlight to a metal surface?

The suspension bracket has powerful magnets. Simply place the flashlight against a metal surface to attach magnetically. Be careful with magnetic fields: keep at least 30 cm away from medical implants and sensitive devices.

Is the battery replaceable?

The battery is built-in and not designed to be replaced by the user. At end of life, the device must be recycled according to WEEE regulations.

What is the maximum beam range?

The announced lighting range is 100 meters, measured under optimal conditions.

What to do if the flashlight no longer turns on?

First check that the battery is charged. Connect the USB-C cable and wait a few minutes. If the indicator does not light up, try another cable or adapter. If the problem persists, contact customer service at www.4K5tools.com.

Completely read through the operating instructions as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and passed on together with the device.

Intended use

The product is intended for illuminating work areas. The work lamp has a floodlight with three light levels and a spotlight with two light levels. To change the operating mode between flood light and spot light, the operating button must be held down for about one second. The light head can be swivelled by 180°. The suspension bracket is equipped with magnets for attaching to metal surfaces. The USB-C interface is available for charging the device.

General safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• The appliance and its accessories are not toys for children.
• Modifications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specifications.
• Handle discharged batteries with care. Battery packs are a source of danger as they can cause very high short-circuit currents. Even if Li-Ion battery packs appear to be in a discharged state, they never discharge completely.
• Avoid physical impacts.
• Impacts, force and penetration of objects can damage the batteries. This can lead to leakage, heat and smoke generation, ignition or explosion.
• A short circuit between the battery pack electrodes may result in burns or fire.
• Protect the battery pack from heat as well as permanent sunlight and fire, e.g. do not leave it in the car in summer, as this can cause explosions.
• Charge the battery pack at ambient temperatures between -10^ and 40^ .
• Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
• The optimum charge level is between 50 % and 80 %.
• Use the mains/charger unit only inside closed rooms, do not expose to moisture or rain, otherwise there is a risk of electric shock.
• Fully charge the battery before using the unit.
• Charging is complete when the power indicator flashes.
• If the battery is weakly charged, the power indicator flashes.
• The battery can also be charged during operation.
• After charging, remove the charging cable and disconnect the power supply unit from the mains.

Safety instructions

Danger - powerful magnetic fields

• Powerful magnetic fields can adversely affect persons with active medical implants (e.g. pacemaker) as well as electromechanical devices (e.g. magnetic cards, mechanical clocks, precision mechanics, hard disks).
• With regard to the effect of powerful magnetic fields on persons, the applicable national stipulations and regulations must be complied with such as BGV B11 §14 „electromagnetic fields" (occupational health and safety - electromagnetic fields) in the Federal Republic of Germany.
• To avoid interference/disruption, always keep the implant or device a safe distance of at least 30 cm away from the magnet.

Safety instructions

Dealing with electromagnetic disturbances

• The device complies with the provisions and limit values for safety and electromagnetic compatibility in accordance with the Low Voltage Directive (LVD) 2014/35/EU and the Electromagnetic Compatibility (EMC) Directive 2014/30/EU.
• Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.

Safety instructions

Using artificial, optical emission (OStrV)

• Do not look into the radiation source.
• Temporary irritating optical effects (e.g. glare, (e.g. glare, flash blindness, after-images, impairment of colour vision) cannot be completely excluded. especially at low ambient brightness.
• The unit operates with light sources of risk group RG 1 (low risk) according to the valid standards for photobiological safety.
• The light source does not pose a hazard when used as intended.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.
