Powermatic 12" Parallelogram Straight Knife Jointer with ArmorGlide 3hp, 1PH, 230V
Now featuring ArmorGlide Technology, the Powermatic 1285T 12-Inch Jointer offers big capacity and performance in a machine loaded with features. A large center-mounted fence assembly adjusts easily by a rack and pinion system with ram lock. Preset stops on the fence body allow for fast angle set-up at 45° in and out, and a positive stop for perfect 90° angles.
The parallelogram design keeps the table in close proximity to the cutterhead for improved finish and allows for a fast depth of cut adjustment. This design also ensures the tables remain perfectly parallel even after years of tough duty. This model features a straight knife cutterhead.

- Wipe down the tables and fence with a mild cleaner to maintain their surface finish and avoid rust.
-
Inspect and Maintain Straight Knives:
- Regularly check the straight knives for dullness or damage. Rotate or replace the knives as needed to maintain cutting precision.
- Make sure the knives are properly aligned with the cutterhead to ensure even cuts.
-
Lubricate Parallelogram Mechanism:
- Apply a light coat of lubricant to the parallelogram mechanism and bed rails to ensure smooth table adjustments.
- Regularly inspect the adjustment handles to ensure they move freely and remain secure during use.
-
Check the Fence and Adjustments:
- Ensure the fence is properly aligned with the table and securely locked in place during operation.
- Clean the fence surface and adjust it as needed to maintain square alignment with the table for precise cuts.
-
Inspect the Motor and Electrical Components:
- Verify the motor is securely mounted and operating without excessive noise or vibration.
- Inspect the wiring and electrical connections for signs of wear, and ensure the power switch functions properly.
-
Dust Collection System Maintenance:
- Regularly check and clean the dust collection port and hose to ensure there are no blockages.
- Empty the dust collection bag or container frequently to maintain efficient dust extraction and prevent overfilling.
-
Inspect and Maintain Tables:
- Periodically inspect the infeed and outfeed tables for levelness and ensure they remain parallel to the cutterhead for smooth cuts.
- Check for any damage to the tables and correct alignment if necessary.
-
Check for Loose Bolts and Fasteners:
- Inspect the machine for loose bolts, screws, or fasteners and tighten them as needed to ensure stable and safe operation.
