5. Instrucións de funcionamento
5.1. Adjusting Drilling Speed
The Einhell BT-BD 501 offers 9 different drilling speeds, ranging from 280 to 2,350 revolutions per minute (RPM). Speed adjustment is achieved by changing the position of the drive belt on the motor and spindle pulleys.
- Desconectar a enerxía: Always unplug the drill before opening the belt compartment.
- Open Belt Cover: Open the top cover to access the drive belts and pulleys.
- Axustar a tensión da correa: Loosen the motor mounting bolts slightly to allow the motor to move and relieve belt tension.
- Seleccionar velocidade: Refer to the speed chart located on the drill head (and inside the belt compartment) to determine the correct belt configuration for your desired speed and material. Move the belt to the appropriate pulley grooves.
- Re-tension Belt: Adjust the motor position to ensure the belt is properly tensioned. The belt should be taut but not overly tight.
- Secure Motor and Close Cover: Tighten the motor mounting bolts and close the belt compartment cover.

5.2. Adjusting the Work Table
The work table can be adjusted for height, tilt, and rotation to accommodate various workpieces and drilling angles.
- Axuste de altura: Loosen the table locking lever, move the table up or down the column to the desired height, and then firmly tighten the lever.
- Inclinación: The table can be tilted from -45° to +45°. Loosen the tilt locking bolt, adjust the table to the desired angle, and re-tighten the bolt.
- Rotación: The table can be rotated around the column. Loosen the table locking lever, rotate the table, and re-tighten.

5.3. Setting Drilling Depth
The drill features a depth stop mechanism to ensure consistent drilling depth for repetitive tasks. The maximum drilling depth is 50 mm.
- Lower the drill bit until it just touches the workpiece.
- Adjust the depth stop collar to the desired depth on the scale.
- Tighten the depth stop to lock it in place. The drill will stop feeding once this depth is reached.

5.4. Inserting Drill Bits
The geared chuck accommodates drill bits from 3 mm to 16 mm. Ensure the drill is unplugged before changing bits.
- Open the chuck jaws using the chuck key.
- Introduza a broca no mandril, asegurándose de que estea centrada e completamente asentada.
- Tighten the chuck jaws firmly with the chuck key. Remove the chuck key immediately after tightening.

6. Mantemento
Regular maintenance ensures the longevity and safe operation of your pillar drill.
- Limpeza: After each use, clean the drill to remove dust, chips, and debris. The drill may come with a protective grease coating; remove this before first use and apply anti-corrosion maintenance as needed.
- Tensión da correa: Periodically check the drive belt tension. A loose belt can slip, reducing drilling efficiency. Adjust as described in Section 5.1.
- Spindle Play Adjustment: Over time, the spindle may develop excessive play. To adjust this:
- Fully extend the spindle by rotating the feed handles.
- Locate the black screw on the left side of the drill head, just above the chuck.
- Loosen the lock nut and then turn the black screw to reduce any excessive movement or play in the spindle.
- Once the desired adjustment is achieved, tighten the lock nut. This adjustment may need to be performed periodically.
- Lubricación: Apply light machine oil to moving parts and pivot points as necessary to ensure smooth operation.
- Inspección de cables eléctricos: Regularly inspect the power cord for any signs of damage. Replace immediately if damaged.
