Cleaning hose
The inside of the pump hose can be easily cleaned by rinsing the pump with clean water. If a
cleaning fluid is added to the water, check if the hose material is resistant to it. Also check if the
pump hose can resist the cleaning temperature.
Changing lubricant
Place a tray under the drain plug on the rear of the pump. Remove the drain plug. Drain the
lubricant from the pump housing into the tray. Replace the drain plug and tighten it firmly.
The pump housing can be filled with lubricant via the breather or via plastic cover. For this purpose
remove the breather cap or the plastic cover and pour the lubricant into the pump housing.
Keep on pouring until the lubricant level has risen above the level line in the lubricant level window
installed at the bottom of the front cover.

6. Turn the rotor ½ revolution with the help of the motor so that the remaining roller is not
pressing against the pump hose
