| D) Pre-lighting Checks Check that the kerosene container is three quarter full. Check that the airscrew is tightened securely. Check that the mantle is securely tied to the burner socket. Remove the ventilator cap and check that the regulating needle is pointing upwards. Check whether the pressure lamp is in good working condition. Do this by first tightening the airscrew and then by pumping in air. Release the airscrew to check whether pressure has build up in the kerosene container. If the pressure gauge shows no change or a decrease in the air pressure, unscrew the pressure gauge to check whether the rubber seal is in good working condition. If the rubber seal is worn out or missing, replace a new one. Remove the mixer flame assembly to check that the cleansing needle is not worn out. This can be achieved by turning the regulator upwards so that you can feel the presence of the cleansing needle with your fingers. E) Maintenance Do not use methylated spirit to clean the glass chimney/ cylinder. Never place the base of the mixer flame assembly directly on the ground to avoid damaging the burner socket. Turn the regulator downwards when replacing the mixer flame assembly to avoid damaging the cleansing needle. Ensure that the glass chimney does not come in contact with water when it is still hot to prevent the glass chimney from cracking. Use the proper tool of the right size when dismantling or assembling the pressure lamp. A spanner with a larger gauge when required will damage the hexagonal shape of the joints. Filter all kerosene before pouring them into the kerosene container. Dirty kerosene will choke the channels of the pressure lamp. Check the washers periodically to ensure that they are firmly embedded in their positions. Replace the leather washer in the air pump if it has been worn off. Simple Repairs to the Pressure Lamp Blockage of kerosene passage - Dismantle the passage tube and use an air jet to blow off the dirt or to a slight extent. Light the lamp and turn the regulator quickly to the left and right. The cleansing needle will force the dirt out of the nipple. Needle too short - unable to block the nipple - Dismantle the kerosene passage and remove the cleansing rod. Adjust the nut at the base of the cleansing rod respectively. Leakage - Determine the leaking part. Dismantle the lamp except for the kerosene passage. Turn the regulator upwards to block out the nipple and tighten all remaining parts. Start pumping until the sign of kerosene shows. If the leakage comes from a joint, tighten it. You may need some soldering plaster if the screw threads are worn off. |
