Depth Stop | Feed Shaft Spring |
Calibration | Tension |
The drill press comes fitted with a depth stop to use when drilling multiple holes at the same depth. The scale on this depth stop can be calibrated if it ever becomes incorrect.
The feed shaft return spring is adjusted at the factory; however, during the life of the drill press you may want to adjust the feed shaft return spring so the feed shaft return pressure suits your operating needs.
To calibrate the depth stop: |
|
|
| |
1. | Loosen the jam nut and calibration nut shown |
|
| |
| in Figure 41. |
|
| Wear safety glasses when |
|
|
|
| |
|
|
|
| adjusting springs. Serious |
|
|
|
| injury may occur if this |
|
|
|
| warning is ignored! |
