This 12 - foot jointer is a powerhouse that combines large capacity with outstanding performance. It comes packed with useful features. The large center - mounted fence assembly can be easily adjusted through a rack and pinion system with a ram lock. The fence body has preset stops, enabling quick angle setup at 45° in and out, and a positive stop for a perfect 90° angle. The parallelogram design keeps the table close to the cutterhead, resulting in a better finish and allowing for fast depth - of - cut adjustments. This design also ensures the tables stay parallel even after years of heavy use. You can choose between the standard straight - knife cutterhead and the helical cutterhead. Key features include a large 12' x 84' precision - ground cast - iron table surface for heavy - duty work, a parallelogram design for close table - to - cutterhead proximity, a rack - and - pinion adjustable cast - iron fence assembly for smooth positioning, a straight - knife cutterhead with 3 high - speed steel knives for clean cuts, and table 'lips' on both sides of the cutterhead to reduce noise. Specifications show a stock number of 1791241, 15,000 cuts per minute, a cutterhead speed of 5000 RPM, a cutting capacity of 11 - 3/4 x 3/4 inches, a required dust - collection CFM of 800, a 4 - inch dust - port outside diameter, a 1 - phase motor with 3 HP and 230V, 3 knives, a prewired voltage of 230V, a Prop 65 warning of cancer and reproductive harm, a recommended circuit size of 30 amps, and a straight - knife cutterhead type.
Using this jointer is quite straightforward. First, set up the fence angle according to your needs. You can use the preset stops on the fence body for quick 45° or 90° angle settings. Adjust the depth of cut using the parallelogram design, which allows for fast and easy adjustments. When it comes to the cutterhead, you can choose between the straight - knife and helical options. For straight cuts, the straight - knife cutterhead with 3 high - speed steel knives works great. Before starting the machine, make sure the dust - collection system is properly connected as it requires a minimum of 800 CFM. The recommended circuit size is 30 amps, so use an appropriate power supply. Safety is crucial. Keep in mind the Prop 65 warning about cancer and reproductive harm. Always wear proper safety gear like goggles and ear protection. For maintenance, regularly clean the precision - ground cast - iron table surface to keep it in good condition. Check the rack - and - pinion adjustable cast - iron fence assembly for any play and adjust it if needed. Also, inspect the knives for wear and replace them when necessary to ensure clean cuts.
