User Manual for IGM 151-DX3 DriftMaster Fence System

Quick guide from the manual

The IGM 151-DX3 DriftMaster Fence System is a precision accessory for bandsaws. This manual provides instructions for assembly, mounting, and calibration. Key operations include adjusting the fence for parallelism, perpendicularity, and blade drift. Always disconnect the machine from the power supply before performing any assembly, repairs, or maintenance.

Product description and parts

The system consists of the main fence, a rack and pinion rail with a scale, an adjustment assembly, and various mounting brackets. Familiarize yourself with the components before assembly. The fence features a drift lock, fence lock knobs, a fence travel lock, and a drift knob for precise control.

Setup and assembly

Approximate assembly and setup time is 30 minutes. Follow these steps:

• Insert the scale into the front channel of the rail with the desired measuring system (inches or mm) facing up.
• Screw the black stop stud into the hole on the right side and tighten with a hex key.
• Install the black knob into the handwheel and tighten the nut.
• Loosen the two black fence lock knobs, slide the fence onto the rail, and tighten the knobs.

Fence mounting

There are multiple mounting options depending on your bandsaw model. Ensure the mounting bracket is not placed over the blade changing slot in the table. If the large bracket extends over the table, it may be attached without the small bracket. If your saw lacks pre-drilled holes, you may need to drill them to align with the mounting brackets. Ensure the rail is parallel to the edge of the tabletop.

Fence operation

The fence can be moved forward and backward by loosening the two fence lock knobs. It can be repositioned to a horizontal position by loosening these same knobs. To move the fence left or right, loosen the fence travel lock and rotate the handwheel. One full rotation moves the fence approximately 7 mm. For quick movement, lift the lock lever for micro-adjustment and extend the red slider.

Adjustments

Parallelism and perpendicularity

If the fence is not parallel to the table, loosen the mounting bolts and use the set screws on the right side to raise the rail. If the fence is not perpendicular (90°) to the table, use the two set screws located between the fence lock knobs to adjust the tilt.

Drift adjustment

To adjust for blade drift: loosen the drift locks, rotate the drift knob to set the fence parallel to the blade, and re-lock. Perform a test cut on a piece of wood at least 250 mm long and 12 mm thick. Inspect the back edge of the blade in the kerf; it should be centered. Adjust the drift knob and repeat until the blade is centered.

Scale adjustment

After tensioning the blade and adjusting for drift, move the fence close to the blade. Measure the distance with a ruler and slide the scale to match this measurement. Tighten the screws on both sides of the scale, being careful not to overtighten.

Maintenance

Regular maintenance is required to keep the system in good working order:

• Keep the fence clean.
• Apply light grease to the adjusting screw for drift and fence tilt once per month.
• Apply light grease to the worm gear once per month.
• Periodically check that all nuts and bolts are tight.
