The pump bearings should be lubricated weekly, applying three to five drops each time.
Check the power supply and motor, remove any foreign objects inside the pump, and inspect the bearings for damage or lack of oil.
No, only flexible rubber or plastic tubing should be used; hard metal connections can cause stress and damage the pump.
Ensure the automatic tensioning device works; if not, loosen the slide screw under the motor until the slide moves freely without gap, then re‑tighten the motor bolts.
