Festool 494391 KL-KS Clamp

Festool 494391 KL‑KS Clamp

The Festool 494391 KL‑KS Clamp is a precision clamping accessory designed for use with Festool’s line of mitre saws, specifically the KS 88 and KS 120 models. It provides secure, adjustable holding power that allows craftsmen to position workpieces accurately while cutting or shaping them.

Key Features

• Adjustable Clamping Range: The clamp can be set from a minimum of 0 mm up to a maximum of 120 mm, matching the full range of the KS 88/KS 120 mitre saws. This flexibility ensures that both small and large workpieces can be held firmly.
• Quick‑Release Mechanism: A single lever action releases the clamp, enabling rapid repositioning or removal of the workpiece without compromising safety.
• Durable Construction: Made from high‑strength steel with a corrosion‑resistant coating, the clamp is built to withstand repeated use in demanding workshop environments.
• Integrated Safety Features: The design incorporates a fail‑safe locking system that prevents accidental release during operation, ensuring user safety and consistent performance.
• Compatibility: Specifically engineered for Festool’s KS 88 and KS 120 mitre saws, the clamp attaches directly to the saw’s mounting bracket via a standard 494391 interface. It also works seamlessly with other Festool accessories that share the same mounting geometry.
• Precision Alignment: The clamp’s jaws are machined to tight tolerances, providing a flat, even surface for the workpiece and minimizing vibration during cutting.

Installation Guide

1. Locate the mounting bracket on your KS 88 or KS 120 mitre saw. The bracket is positioned near the base of the saw’s table, designed to accept a 494391 clamp.

2. Align the clamp’s mounting holes with those on the bracket. Ensure that the clamp faces the correct direction for left‑hand or right‑hand positioning, depending on your cutting orientation.

3. Screw the clamp into place using the supplied fasteners. Tighten evenly to avoid warping the bracket or compromising the clamp’s alignment.

4. Adjust the clamping range by sliding the lever until the desired jaw width is achieved. Lock the position with the safety latch.

Operational Tips

• Secure Placement: Always double‑check that the clamp is fully locked before starting a cut. A loose clamp can shift, leading to inaccurate cuts or potential injury.
• Regular Inspection: Inspect the jaws and locking mechanism for wear or damage after every 50–100 uses. Replace any worn components promptly to maintain optimal performance.
• Clean Jaws: Keep the clamping surfaces free of sawdust, glue, or other debris. A clean contact surface ensures maximum grip and reduces vibration.
• Use with Proper Workpiece Orientation: Position the workpiece so that its edge aligns with the clamp’s jaws. This alignment minimizes stress on the material and improves cutting accuracy.

Applications

The Festool 494391 KL‑KS Clamp is ideal for a wide range of woodworking tasks, including:

• Miter Cuts: Secure panels or trim pieces before making precise angled cuts with the KS mitre saw.
• Crosscuts and Rip Cuts: Hold boards firmly while cutting straight lines across or along the grain.
• Routering and Shaping: Keep workpieces stable during router passes, ensuring clean edges and consistent depth control.
• Panel Assembly: Use the clamp to hold panels in place while drilling or fastening joints.

Maintenance Recommendations

• After each session, wipe down the jaws with a dry cloth to remove sawdust and moisture. This prevents rust buildup.

• Apply a light coat of machine oil to moving parts every few months to maintain smooth operation.

• Store the clamp in a dry environment when not in use. Avoid prolonged exposure to humidity or extreme temperatures.

Compatibility Summary

The Festool 494391 KL‑KS Clamp is specifically designed for:

• Festool KS 88 Mitre Saw
• Festool KS 120 Mitre Saw
• Other Festool accessories that share the same mounting geometry, such as certain table clamps and workpiece holders.

Its standardized 494391 interface ensures seamless integration with existing Festool systems, allowing users to upgrade or replace clamping solutions without modifying their current setup.

Conclusion

The Festool 494391 KL‑KS Clamp delivers reliable, adjustable clamping performance tailored for the KS series mitre saws. Its robust construction, safety features, and ease of installation make it an essential tool for professionals seeking precision and consistency in their woodworking projects.
