Haas Automation CNC Horizontal Machining Center HS-6

Warning: This procedure requires trained personnel with PPE!

Remove the screws that hold the oil reservoir to the pump body, carefully lower the reservoir and set aside.

Use a strap wrench, pipe wrench or adjustable pliers to unscrew the end cap. Use a screwdriver or similar tool to stop the filter from turning while the end cap is removed.

Remove the oil filter element from the filter body once the end cap is removed.

Clean the inside of the filter housing and the filter end cap as required.

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.

Replace the oil reservoir; ensure the gasket seats properly between the reservoir and the top flange.

• 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.

Coolant replaced and coolant tank cleaned?

All hoses and lubrication lines checked for cracking?

Rotary A-axis checked and oil added if necessary?

Parts lubricated with red grease

Arm Shaft lubricated with Moly grease?

• 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.
