Powermatic 15HH manual Dust Collection, Table and Adjustment

The dust chute angles the 4”-diameter port to the side so the hose does not hang in the way of the wood as it exits from under the cutterhead.

covers. The operators’ manual included with the POWERMATIC 15HH has a full set of illustrated instructions for making these adjustments.

To enhance operator safety, we added a row of closely spaced anti kickback fingers. These steel fingers are gravity operated and require no adjustment. They automatically engage the wood as it enters the cutterhead and help prevent it from being kicked out.

While the POWERMATIC 15HH is capable of 3/16”-deep cuts on most stock widths, a limiter plate at the center of the cutterhead limits full-width cuts to 1/8” or less. Controlling full-width cut depth avoids applying excessive strain to the machine but also prevents damaging the wood. Deep cuts are far more likely to produce chipping and tearout

because of the extraordinary stress applied to the wood fibers.

Dust Collection

The POWERMATIC 15HH generates large quantities of dust and chips that must be evacuated to maintain performance at the cutterhead. The efficiency of the POWERMATIC 15HH doesn’t reduce that quantity though its cutting action does tend to produce smaller particles than a long knife machine. We recommend a 500-600CFM (cubic feet per minute minimum) dust collector to handle the flow of chips properly.

An all-metal dust hood comes with the POWERMATIC 15HH that creates a short, direct path for the debris directly from the

cutterhead. The hood terminates with a 4”-diameter port that is angled to the side so the dust collector hose does not interfere with the stock as it exits.

Table and Adjustment

Table height is adjusted with a large (left) cast iron handwheel with a spinner knob. A pair of locking knobs (right) one at each end of the table locks it in position firmly. These locking knobs can be moved to the opposite side of the 15HH if space is an issue.

The main and extension cast iron table surfaces are precision ground for precise planning. The main table surface is 20”-long by 15”-wide and is fully captured on four round, 2”- diameter, precision ground steel posts. Each corner of the table is locked onto a lead screw within its post that controls the up and down movement. The lead screws are driven by a single chain through a gear drive. A large 6”- diameter cast iron handwheel with spinner handle drives the height adjustment mechanism. Each full
