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.
- Ngắt nguồn: Always unplug the drill before opening the belt compartment.
- Open Belt Cover: Open the top cover to access the drive belts and pulleys.
- Điều chỉnh độ căng của dây đai: Loosen the motor mounting bolts slightly to allow the motor to move and relieve belt tension.
- Chọn tốc độ: 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.
- Điều chỉnh chiều cao: Loosen the table locking lever, move the table up or down the column to the desired height, and then firmly tighten the lever.
- Nghiêng: 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.
- Sự xoay vòng: 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.
- Lắp mũi khoan vào mâm cặp, đảm bảo mũi khoan được đặt chính giữa và khớp hoàn toàn.

- 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.
- Bôi trơn: Apply light machine oil to moving parts and pivot points as necessary to ensure smooth operation.
- Electrical Cord Inspection: Thường xuyên kiểm tra dây nguồn xem có dấu hiệu hư hỏng nào không. Thay thế ngay lập tức nếu bị hư hỏng.
