Machine Stalls or It's Underpowered - AF50

Problem

The machine stalls, or you find that it’s underpowered during operations.

Cause

The feed rate may be high, or you may be using the wrong blade.

You May Need To…	Probability	How-To Steps	Need More?
Raise the vertical quick-adjustment nut.	High	During automatic operation, verify that the blade can’t collide with the material while it initially lowers: raise the vertical quick-adjustment nut. The blade can break or stall when it drops from the raised position and then collides with the part before the feed rate is controlled.	For more information, see “ Use Automatic Mode”.
Use a different blade.	High	Verify that the blade’s TPI isn’t to high, or that the material isn’t too course: you must use the correct blade for the material. If you’re not, you may need to choose a new blade.	For information, see “ Choose a Blade”.
Adjust the feed rate or cutting speed.	High	Verify that the feed rate isn’t too high: lower the feed rate, and then do a test cut. Examine the behavior of the machine as it cuts. Verify that the cutting speed isn’t too high: lower the cutting speed, and then do a test cut. Examine the behavior of the machine it cuts.	For information, see “ Change the Feed Rate” or “ Change the Speed”.
Examine the workpiece setup.	Medium	Manual Operation Verify that the workpiece isn’t too loose: use the handwheel to tighten the clamp on the front vise. If necessary, use a jig to hold the workpiece. Automatic Operation Examine the vise clamps: verify that there is 1/8 in. or less of a gap between the clamps and the material. Then, verify that the vise jaw clamping pressure isn’t set too low for the material.	For information, see “ Use Automatic Mode” or “ Use Manual Mode”.
Adjust the blade’s tension.	Low	Verify that the blade isn’t too tight or too loose between the wheels. If necessary, use the tensioner on the top of the saw head to adjust the blade’s tension.	For information, see “ Change a Blade”.
Examine the main power supply voltage.	Low	Test the hot lines to confirm that they have the correct voltage on both legs.	For information, see “Electrical Schematics”.
Rewire the plug/receptacle.	Low	Test the contacts. If necessary, make the correct connections.	For information, see “Electrical Schematics”.
Rewire the motor.	Low	Inspect the motor wiring. If necessary, make the correction connections.	Create a support ticket with Tormach Technical Support at http://tormach.com/how-to-submit-a-support-ticket for guidance on how to proceed.
