The tool pot chain tension should be checked regulary as a preventative maintenance procedure. Chain tension adjustment is performed in the lower left area of the magazine. Loosen the four 12x50 SHCS from the front of the magazine.

This will allow the plate to move. Loosen the hex lock nut on the shaft and tighten the shaft using the hex bolt. Lock in the adjustment with the hex lock nut, and retighten the four 12x50 SHCS. Tensioning will not change the indexed pot location, but check the alignment between the manual tool push cylinder and the tool pot.;

• Check Through the Spindle Coolant (TSC) filters. Clean or replace element if needed.

• Check for proper operation of auto drain on filter regulator.

• On machines with the TSC option, clean the chip basket on the coolant tank.

Remove the tank cover and remove any sediment inside the tank. Disconnect the coolant pump from the cabinet and power off the machine before working on the coolant tank.

Do this MONTHLY for machines without the TSC option.

• Check air gauge/regulator for 85 psi. Check the spindle air pressure regulator for 17 psi. For 15K-spindle machines, check spindle air pressure regulator for 20 psi.

• For machines with the TSC option, place a dab of grease on the V-flange of tools.

Do this MONTHLY for machines without the TSC option.
