2. Product Components

Familiarize yourself with the main components of your Dasqua Magnetic Base:

This diagram labels the key parts:

• Magnetic Base: The primary unit containing the permanent magnet and ON/OFF switch.
• Main Pole: The vertical rod extending from the base.
• Sub Pole: The horizontal rod, adjustable for reach.
• Lower Fixture: Secures the main pole to the base.
• Upper Fixture: Connects the main pole to the sub pole.
• Fine Adjustment: A mechanism for precise, small movements of the indicator.
• Indicator Clamping Screw: Used to secure a dial indicator or other measuring device.

3. Setup and Installation

1. Unpacking: Carefully remove the magnetic base and its components from the packaging. Inspect for any damage.
2. Base Placement:

   Ensure the surface where the magnetic base will be placed is clean, flat, and ferrous (magnetic). The base features a V-groove for secure mounting on cylindrical parts.

   

   This image highlights the V-grooved design on the bottom of the magnetic base, which facilitates stable attachment to round workpieces or surfaces.

3. Activating the Magnet: Turn the ON/OFF switch on the magnetic base to the "ON" position. This will activate the powerful permanent magnet, securing the base to the ferrous surface.
4. Assembling the Arm: If the arm components (main pole, sub pole, fixtures) are not pre-assembled, connect them as shown in the component diagram (Figure 2.1). Ensure all clamping screws are finger-tight to allow for adjustment.
5. Mounting the Indicator: Insert your dial indicator or measuring device into the clamping hole at the end of the sub pole. The clamping holes are designed to accommodate 6mm, 8mm, and 3/8 inch diameter shanks. Tighten the indicator clamping screw to secure the indicator.



This image illustrates the various clamping hole diameters (4mm, 8mm, and 3/8 inch) available on the magnetic base's arm for attaching different indicators.

4. Operating Instructions

1. Positioning the Base: With the magnet in the "OFF" position, place the base on the desired ferrous surface. Once positioned, turn the switch to "ON" to secure it. The base provides 132 lbs (60 kg) of holding force.

2. Adjusting the Arm: Loosen the clamping screws on the upper and lower fixtures to adjust the main and sub poles to the desired height and angle. The chrome-plated rods allow for smooth movement. Once the approximate position is achieved, tighten the clamping screws firmly.
3. Using Fine Adjustment: For precise positioning of the indicator, use the fine adjustment knob. This mechanism allows for minute movements of the indicator without needing to loosen and readjust the main arm clamps.



This series of diagrams illustrates how the fine adjustment knob operates, enabling precise, small movements of the indicator arm for accurate measurement setup.

4. Disengaging the Magnet: When finished, turn the ON/OFF switch on the magnetic base to the "OFF" position to release the base from the surface.

5. Maintenance

• Cleaning: Keep the magnetic base and its components clean and free from dust, debris, and metal shavings. Use a soft, dry cloth. For stubborn grime, a mild cleaner can be used, ensuring no liquid enters the internal mechanism.
• Storage: Store the magnetic base in a dry, clean environment when not in use. Ensure the magnet is in the "OFF" position during storage to prevent accidental attachment to other tools or surfaces.
• Inspection: Periodically inspect the rods for any signs of damage or corrosion. The chrome-plated rods are designed for durability, but proper care extends their lifespan.
• Lubrication: No specific lubrication is typically required for the magnetic base mechanism or rods. Avoid applying oils or greases that could attract metal particles.

6. Troubleshooting

• Base Not Holding Firmly:
  • Ensure the ON/OFF switch is fully in the "ON" position.
  • Verify the mounting surface is ferrous (magnetic) and clean. Rust, paint, or debris can reduce magnetic force.
  • Check for any gaps between the base and the mounting surface.
• Arm Movement is Stiff:
  • Loosen the clamping screws on the fixtures.
  • Clean the rods and inside the clamping mechanisms to remove any accumulated debris.
• Indicator Not Holding Securely:
  • Ensure the indicator's shank diameter matches one of the clamping hole sizes (6mm, 8mm, or 3/8 inch).
  • Tighten the indicator clamping screw firmly.
