Visual automatic oiler instructions

The 1741-V visual automatic oiler is designed for long-term stable lubrication and oil supply.

The visual auto-oiler consists of a medium-duty spring (green), a light-duty spring (orange) and a heavy-duty spring (black). When used, the correct spring is selected according to the lubricant. #0-#3 grease can be used.


All models of lubricant oilers (both manual and electric) have a standard lubricant coupling for grease to the oil cup and embedded fuses to prevent overfilling or cup pressure Too high.
