Hoffmann PP2 Dovetail Routing Machine

9. Machine Operation

9.1 Standard 45-degree miters with one key per joint
The machine is equipped with a routing height adjustment rod (2). The scale (3) on the vertical bar
indicates the height the router bit will travel into the material. To adjust the height, simply loosen the locking
lever (1) and move the bar to the desired height.
Always use the longest key possible to achieve a tight joint on the face side of the workpiece.
With the routing height and the keyway position set, place the material on the table and lower the
pneumatic hold-down clamps to within 1/8" above the workpiece. Secure the setting by tightening the
orange handles.
Start the routing operation by depressing the pneumatic foot pedal. Do not release the switch until the
routing sequence is completed and the routers have returned to their home position. Once the clamps have
released the workpieces, they can be removed from the table.
Before routing the material make sure the orange handles securing the hold-down clamps and the steel
fence plate are properly tightened, and do not change the settings until booth parts are routed.
9.2 Standard 45-degree miters with multiple keys per joint
Adjust the machine and process the material for one dovetail key as described above.
After all material has been machined for the first key location, re-set the steel fence plate (1) on the
machine table (and re-set the routing height if necessary) and proceed as before.
