Remedy |
| Hydraulic supply pressure too low. | Supply pressure should be between 300-500 psi. | Regulate. |
| Thrust required to advance tool at desired feed rate approaches or exceeds thrust developed by Holomatic. | Consult drilling speed, feed and thrust charts and compare with developed thrust of unit. | Decrease feed rate. Increase input supply pressure. Stagger drill lengths. Decrease size or number of tools. |
