No lubrication is necessary for this instrument; no special tools are re- quired for its overhaul. BATTERIES. —Three size D (standard flash- light) dry cell batteries are required. To insert the batteries, remove the sliding door at the end of the case and rotate the spring contact from the battery compartment to the bottle compartment. The batteries must be inserted so that the center contact enters the compartment first. After the batteries are in place, rotate the spring contact to its original position on the end battery and replace the sliding door. REPLACING THE WICK. —To replace the wick, first remove the sliding air intake ex- posing the thermometer bulbs. Then remove the wick. Slip a length of wicking over the bulb. Secure at the top of the bulb with a thread at the constriction between the bulb and the stem, using a loop and square knot. Form a loop in a second thread and place it at about the middle of the bulb, stretching the wick firmly and snugly against the bulb. Tie with a double loop and square knot at the end of the bulb. Clip the ends of the thread and cut off the excess wicking about one-eighth inch below the bottom of the bulb. REMOVING AND REPLACING THERMOM- ETERS.—If either thermometer is damaged, it is necessary to remove both thermometers and replace them with a matched pair. To remove and replace the thermometers, first remove the air intake and the thermometer 59.
