3. Configuració

Carregant la bateria

The JUEMEL 20V Cordless Drill comes with two 1500mAh Li-Ion batteries. Before first use, fully charge the battery. A full charge typically takes approximately 1 hour.

1. Connecteu el carregador a una presa de corrent estàndard.
2. Slide the battery pack onto the charger base. Ensure it clicks into place.
3. The charger's indicator light will show red during charging. Once fully charged, the light will turn green.
4. Once charging is complete, disconnect the charger from the power outlet and remove the battery.

Figure 3.1: Illustration of the battery charging process. The charger light indicates red when charging and green when fully charged. Two batteries are included for continuous work.

Instal·lació i extracció de la bateria

• Per instal·lar: Alineeu el paquet de bateries amb la base del mànec del trepant i feu-lo lliscar fins que encaixi fermament al seu lloc.
• Per eliminar: Press the battery release button (usually located on the front or sides of the battery) and slide the battery pack out of the drill handle.

Installing Drill Bits and Accessories (Keyless Chuck)

The drill features a 3/8-inch (10mm) keyless chuck for quick and easy bit changes.

1. Ensure the drill is off and the forward/reverse switch is in the center (locked) position to prevent accidental starting.
2. Grip the rear collar of the chuck with one hand and rotate the front collar counter-clockwise with the other hand until the chuck jaws are open wide enough to insert the bit.
3. Insert the desired drill bit or accessory into the chuck jaws. Ensure the bit is inserted as far as possible without touching the chuck body.
4. Rotate the front collar clockwise to tighten the chuck jaws firmly around the bit. Hand-tighten until the bit is secure.
5. Per eliminar: Reverse the process by rotating the front collar counter-clockwise.

4. Funcionament del trepant

Activador de velocitat variable

The drill features a variable speed trigger, allowing you to control the drilling speed by the amount of pressure applied. Pressing the trigger lightly results in lower speed, while pressing it fully increases the speed up to the maximum setting.

2-Speed Setting

A 2-speed selector switch is located on top of the drill. This allows you to choose between two main speed ranges:

• Posició 1 (baixa velocitat): 0-450 RPM. Ideal for driving screws, larger drilling diameters, or applications requiring higher torque and more control.
• Posició 2 (Alta velocitat): 0-1450 RPM. Suitable for faster drilling in softer materials or smaller drilling diameters.

Clutch / Torque Adjustment (18+1 Positions)

The torque adjustment collar, located behind the chuck, allows you to set the amount of torque the drill will apply before the clutch disengages. This prevents over-driving screws or damaging the workpiece. The 18+1 settings include:

• Configuració 1-18: For driving screws. Lower numbers are for smaller screws or softer materials; higher numbers are for larger screws or harder materials.
• Drill Symbol (Drill Mode): Per a aplicacions de perforació. Aquesta configuració evita l'embragatge, proporcionant el parell màxim per a la perforació.

Interruptor cap endavant/marrere

The forward/reverse switch is located above the trigger. It controls the direction of rotation:

• Posició esquerra: Forward rotation (for drilling and driving screws).
• Posició correcta: Rotació inversa (per treure cargols o retirar puntes).
• Posició central: Locks the trigger, preventing accidental starting. Always set to the center position when changing bits, performing maintenance, or storing the tool.

Llum de treball LED

The integrated LED work light automatically illuminates when the trigger is pressed, providing visibility in dimly lit work areas. It remains on for a short period after the trigger is released.

Portabits magnètic

A magnetic bit holder is conveniently located on the back of the drill, allowing you to store frequently used drill or driver bits for quick access during tasks.
