33. HANDLING AUTO-GREASING SYSTEM 33.1.5 METHOD FOR BLEEDING AIR 1. When there is air in piston portion of pump 1. Remove the air bleed screw (hexagon head socket plug 1/8) from the side of the pump. 2. Turn the power on, press the SET/START key, and run the pump. 3. Continue to run the pump until no more bubbles come out with the grease from the pump. 4. After checking that clean grease comes out continuously, turn off the power and stop the pump. 5. Install the air bleed screw to its original position in the pump. 2. When there is air in piping 1. After installing the divider valve, remove the plug from the greasing port of the divider valve at the end. 2.
Run the grease pump until no more bubble come out with the grease from the pump. 3. Connect the grease piping to the discharge port of the divider valve, rotate the pump several times, and check that grease comes out, then connect the bearing end also. Method of checking operation in cold areas If the temperature suddenly drops, grease may not come out if the pump is operated only once. If the grease comes out after the pump is operated 2 or 3 times, this does not indicate any abnormality in the system.
Greasing with grease gun If the auto-greasing system does not work properly and does not supply grease, it is possible to carry out greasing by pumping in grease manually with a grease gun through the grease fittings installed to each divider valve. 5-39
