Under normal laboratory operating conditions, the hydraulic oil in the GenNotch 4000UPG should be replaced approximately every 6 to 12 months. This interval may vary depending on the frequency of use, ambient temperature, and cleanliness of the working environment.

Regular oil maintenance is essential to preserve the efficiency of the lubrication and hydraulic systems. Over time, oil can accumulate fine metal particles and impurities that reduce its protective properties and increase component wear. Before each replacement, the oil level and clarity should be inspected through the system’s viewing port or dipstick.

When performing an oil change, it is recommended to use the specified L-HM46 anti-wear hydraulic oil or an equivalent grade to maintain smooth broacher motion and stable pressure control. Proper oil management not only extends the service life of internal components but also ensures consistent cutting precision and smooth operation.
