• 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.

• Clean exterior surfaces with mild cleaner. DO NOT use solvents.

• Replace the gearbox oil. Drain the oil from the bottom of the gearbox.

Remove inspection cover beneath spindle head. Add oil slowly from top until oil begins dripping from overflow tube at bottom of sump tank. For 50 taper spindles, add oil from the side of the transmission.

• Check oil filter and clean out residue at bottom of filter.

• Check SMTC oil level in sight glass, (see Side Mount Tool Changer Oil Level in this section).

• Lubricate the Changer Slide Linear Guide with red grease.;

• Replace air filter on control box every 2 years.

• EC-400 Replace the Rotary A-axis oil

1. Remove the fourteen (14) BHCS on the right Z-axis way cover at the receiver end and slide it toward the column.

2. Remove the left Z-axis way cover: Jog the Z-axis all the way toward the column and rotate the H-frame 45° counter clockwise. Remove the thirteen (13) BHCS that fasten the waycover to the receiver and remove it through the door at the control pendant.

3. Disconnect the reservoir at the rotary indexer end and plug the end of the hose.

4. Remove the drain plug on the opposite side of the rotary indexer. Replug the hole when the oil has drained.

5. Remove the air escape hole plug on the side of the platter.

6. Fill the rotary table until oil begins to escape from the air escape hole and plug it.

7. Replace the reservoir hose and the way covers. Command the receiver 180° to 0° repeatedly for fifteen minutes.
