2. Sicherheitshinweise

Sicherheit hat beim Umgang mit Elektrowerkzeugen stets oberste Priorität. Die Nichtbeachtung dieser Anweisungen kann zu schweren Verletzungen oder Schäden am Werkzeug führen.

• Lesen Sie das Handbuch: Machen Sie sich vor der Benutzung mit allen Bedienelementen, Einstellungen und Arbeitsabläufen vertraut.
• Tragen Sie persönliche Schutzausrüstung (PSA): Always wear safety glasses or goggles. Hearing protection and a dust mask are also recommended, especially during prolonged use or when drilling materials that produce fine dust.
• Werkstück sichern: Immer clamp the workpiece firmly to the drill table. Never hold it by hand, as it can spin violently and cause injury.
• Halten Sie die Hände frei: Keep hands and fingers away from the rotating drill bit and chuck.
• Vor der Justierung vom Stromnetz trennen: Disconnect the drill from the power supply before changing drill bits, making adjustments, or performing any maintenance.
• Halten Sie Ihren Arbeitsbereich sauber: Keep your work area well-lit and free of clutter.
• Use Correct Drill Bits: Ensure the drill bit is sharp, correctly sized for the chuck, and suitable for the material being drilled.
• Überforderung vermeiden: Achten Sie jederzeit auf sicheren Stand und Gleichgewicht.
• Auf Schäden prüfen: Before each use, inspect the drill for any damaged parts. Do not operate if damaged.
• Not-Halt: Know the location of the power switch and how to quickly turn off the machine in an emergency.

4. Aufbau und Montage

The assembly of the Einhell BT-BD 501 Pillar Drill is designed to be straightforward. Follow these steps:

1. Auspacken: Carefully remove all components from the packaging. Note that parts may be coated with industrial oil for rust prevention; clean these thoroughly before assembly.
2. Sockel- und Säulenmontage: Secure the column to the base plate using the provided screws.
3. Montage des Arbeitstisches: Slide the work table onto the column and secure it at the desired height.
4. Drill Head Mounting: Place the drill head assembly onto the top of the column and fasten it securely.
5. Feed Handle Attachment: Screw the three feed handles into the drill head to control the spindle movement.
6. Montage des Spannfutters:
   • Open the chuck jaws to their maximum extent so they retract fully.
   • Align the tapered end of the chuck with the spindle.
   • Using a rubber mallet, firmly tap the chuck onto the spindle. The conical fit requires a few decisive taps to ensure a secure connection.

5. Bedienungsanleitung

5.1. Einstellen der Bohrgeschwindigkeit

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.

1. Stromversorgung trennen: Always unplug the drill before opening the belt compartment.
2. Open Belt Cover: Open the top cover to access the drive belts and pulleys.
3. Adjust Belt Tension: Loosen the motor mounting bolts slightly to allow the motor to move and relieve belt tension.
4. Geschwindigkeit auswählen: 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.
5. Nachspannriemen: Adjust the motor position to ensure the belt is properly tensioned. The belt should be taut but not overly tight.
6. 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.

• Höhenverstellung: Loosen the table locking lever, move the table up or down the column to the desired height, and then firmly tighten the lever.
• Kippen: 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.
• Drehung: The table can be rotated around the column. Loosen the table locking lever, rotate the table, and re-tighten.

5.3. Einstellen der Bohrtiefe

The drill features a depth stop mechanism to ensure consistent drilling depth for repetitive tasks. The maximum drilling depth is 50 mm.

1. Senken Sie den Bohrer ab, bis er das Werkstück gerade berührt.
2. Adjust the depth stop collar to the desired depth on the scale.
3. 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.

1. Öffnen Sie die Spannbacken mit dem Spannfutterschlüssel.
2. Setzen Sie den Bohrer in das Bohrfutter ein und achten Sie darauf, dass er zentriert und vollständig sitzt.
3. Tighten the chuck jaws firmly with the chuck key. Remove the chuck key immediately after tightening.

6. Wartung

Regelmäßige Wartung gewährleistet die Langlebigkeit und den sicheren Betrieb Ihrer Säulenbohrmaschine.

• Reinigung: 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.
• Gurtspannung: 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:
  1. Fully extend the spindle by rotating the feed handles.
  2. Locate the black screw on the left side of the drill head, just above the chuck.
  3. Loosen the lock nut and then turn the black screw to reduce any excessive movement or play in the spindle.
  4. Once the desired adjustment is achieved, tighten the lock nut. This adjustment may need to be performed periodically.
• Schmierung: Apply light machine oil to moving parts and pivot points as necessary to ensure smooth operation.
• Electrical Cord Inspection: Überprüfen Sie das Netzkabel regelmäßig auf Beschädigungen. Ersetzen Sie es umgehend, falls es beschädigt ist.
