15.0 Lubrication schedule and general maintenance
Regularly scheduled maintenance is crucial to ensure a long service life for your machine. The schedule below shows
general cleaning, lubrication points and coolant replacement information for the ZH Series Lathes.
Push stop button
and power off before lubricating. Follow local regulations for disposal of used coolant/lubricants. Minimize direct
skin contact with lubricants and coolants, and wear eye protection when pouring coolant in case of splash.
Mobile DTE® Oil Heavy Medium is recommended for the SAE-20W machine oil.
If the brand of oil is ever changed, it is recommended that you flush and clean the reservoir first to prevent any
compatibility issues.
