Setup and Installation
The Prazi 12" replacement chain is designed for convenient installation on your Prazi Beam Cutter attachment. Ensure your circular saw is unplugged before beginning.
- Prepare the Saw: Disconnect the circular saw from its power source. If applicable, remove the existing chain from your Prazi Beam Cutter attachment.
- Attach the Beam Cutter: Ensure your Prazi Beam Cutter (PR-7000 or PR-2700) is correctly installed on your circular saw. The attachment is compatible with most 7.25" and 8.25" circular saws from brands like Skil, Bosch, Makita, DeWalt, and Craftsman.
- Install the New Chain: Carefully place the new Prazi P7020 chain onto the guide bar and around the drive sprocket of the beam cutter attachment. Ensure the cutting teeth are oriented in the correct direction for cutting.
- Adjust Chain Tension: Adjust the chain tension according to the instructions provided with your Prazi Beam Cutter attachment. The chain should be snug but still able to be pulled freely around the guide bar by hand. Over-tightening can cause premature wear, while too loose can cause derailing.
- Verify Installation: Double-check all connections and ensure the chain is properly seated and tensioned before reconnecting power to the saw.

Operating Instructions
The Prazi 12" replacement chain, when used with its compatible beam cutter attachment, allows for deep and precise cuts in various timber applications.
- Cutting Applications: This chain is suitable for cross-cutting, ripping, and various cuts on materials such as foam insulated panels, timber frame beams, landscaping timbers, stair stringers, glulam beams, fence posts, rafters, and logs.
- Achieving Precise Cuts: The design of the chain and beam cutter allows for smooth, precise cuts. For optimal results, ensure the workpiece is stable and use a guide if necessary to maintain a straight cutting line.
- Cutting Depth: The Prazi Beam Cutter attachment significantly increases the cutting capacity of your circular saw, allowing for cuts up to 12 inches deep with this chain.
- Lubrication: During extended use, it is recommended to periodically spray the guide bar with WD40 or silicon oil every 2-3 feet of cutting to ensure smooth operation and reduce friction.

Maintenance
Proper maintenance of your Prazi replacement chain will extend its lifespan and ensure consistent cutting performance.
- Chain Sharpening: The chain can be sharpened as needed to maintain optimal cutting performance. A simple chainsaw sharpener kit with files can be used. Sharpening frequently will ensure clean cuts and reduce strain on the tool.
- Lubrication: Regularly lubricate the guide bar and chain with appropriate bar and chain oil or a light machine oil like WD40 or silicon oil, especially during prolonged use. This reduces friction and heat buildup.
- Cleaning: After each use, clean the chain and guide bar to remove sawdust, resin, and debris. This prevents buildup that can hinder performance and cause wear.
- Storage: Store the chain and beam cutter attachment in a clean, dry place to prevent rust and damage.
