Warning: This procedure requires trained personnel with PPE!

Did you remove the screws that hold the oil reservoir to the pump body?

Did you carefully lower the reservoir and set it aside?

Did you use a strap wrench, pipe wrench or adjustable pliers to unscrew the end cap?

Caution: Use a screwdriver or similar tool to stop the filter from turning while the end cap is removed.

Did you remove the oil filter element from the filter body once the end cap is removed?

Did you clean the inside of the filter housing and the filter end cap as required?

Did you install the new oil filter element (p/n 94-3059), O-ring and the end cap?

Use the same tools that were used to remove the filter end cap, to tighten it - Do Not Over Tighten.

• 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 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.

Warning: This maintenance check requires trained personnel with PPE!

Check the dirt indicator on the 100-micron mesh filter with the TSC system running and no tool in the spindle. Is it in the red zone?

If the dirt indicator is in the red zone, change the element.

Clean the pump intake filter when indicator is in the red zone. Is it clean now?

After changing or cleaning filter elements, run TSC system with no tool in spindle for at least one minute to prime system.

Warning: Use of coolants with extremely low lubricity can damage the TSC coolant tip and pump.

Warning: Increased maintenance schedules are absolutely required with abrasive swarf. The coolant must be changed more often and the tank thoroughly cleaned of sediment on the bottom. An auxiliary coolant filter is recommended.

Warning: When machining castings, sand from the casting process and the abrasive properties of cast aluminum and cast iron will shorten pump life unless a special filter is used in addition to the 100 mesh suction filter.
