HANDLING AUTO-GREASING SYSTEM
PRECAUTIONS WHEN HANDLING AUTO-GREASING SYSTEM
Basically, the power source input to the lubrication controller should be DC24V, but use a maximum limit of 30V.
The grease nipple installed to the service port used for initial charging of the divider valve has a ball check
structure, so it may leak if dirt gets stuck in it.
Check it from time to time, and replace the grease nipple immediately if any grease is leaking.
When carrying out initial operation or when the grease tank is empty, air may get into the piston portion of the
pump. If the pressure does not rise within the specified time when running the pump, and an error is displayed
for the controller, bleed the air.
If the divider valve or grease piping are removed when replacing the attachment on the machine, handle carefully
to prevent any damage. When storing or installing again, be extremely careful to prevent the entry of air, and
particularly dirt. If there is any air in the system, bleed the air immediately.
TROUBLESHOOTING
If any problem occurs in the greasing system, the error codes will flash alternately to display the type of problem.
