| '''Test before use - make sure blades are not interfering with each other.'''
| |
|
| |
| 1. Step on Foot Lever
| |
|
| |
| 2. As the foot lever travels downward, the Hold Down will press against the work piece at about half way. The Foot Lever will stop at this point.
| |
|
| |
| 3. To engage the cutting blade and perform the cut, use both feet to “jump" on the Foot Lever and press it to the floor.
