Monthly:

     1. Check the pneumatic supply .Drain the Filter Regulator and Lubricator (FRL) unit and release the
        moisture by pushing the button provided at the bottom of the FRL unit.
     2. Set the pressure at 4.5 to 8.5 kg/ cm2 in FRL unit
     3. Check the Lubrication oil level in FRL unit and top up if required.
     4. Before mounting of the pump, ensure the follower plate is properly seated inside the grease drum.
     5. Check the inlet air pressure of pneumatic grease pump (4.5 to 8.5 kg/cm2).
     6. Clean the holes and grooves of the greasing fixture thoroughly.
     7. Check and Ensure that electrical connections are in tighten condition.
     8. Ensure proper cleaning of electrical equipment with electric blower.
     9. Check the condition of insulation of wiring if damage replace it.

     4. Check the operation of the Pneumatic Grease Pump
     5. Use only rated MCB, replaced if completes its codal life.
     6. Check the earth pit condition, measure the earth resistance periodically.

NOTE:

     * Rotating the adjusting nut one round in anti- clockwise direction will increase the quantity of
        grease by approximately 4 grams. Similarly, rotating the adjusting nut one round in clockwise
        direction will decrease the quantity of grease by approximately 4 grams.
