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. Be careful to disconnect the coolant pump from the controller and POWER OFF the control before working on the coolant tank. Do this MONTHLY for machines without the TSC option.

Check air gauge/regulator for 85 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.

Check the hydraulic counterbalance pressure according to the machines specifications.;

Check oil level in gear box. For 40 taper spindles: Remove inspection cover beneath spindle head. Add oil slowly from top until oil begins dripping from overflow tube at bottom of sump tank. See section 1.4. For 50 taper spindles: Check oil level in sightglass. Add from side of gearbox if necessary. See section 1.5.

Inspect way covers for proper operation and lubricate with light oil, if necessary.

Place a dab of grease on the outside edge of the guide rails of the tool changer and run through all tools.

Replace coolant and thoroughly clean the coolant tank. (6 Monthly CNC Horizontal Machining Center Maintenance)

Check all hoses and lubrication lines for cracking. (6 Monthly CNC Horizontal Machining Center Maintenance);

Warning: This maintenance check requires trained personnel with PPE!

Way lube lubrication tank level reading

Way covers and bottom pan cleaned from chips?

Tool changer cleaned from chips?
