Illust. 34 Taking a hydrameter reading af electrolyte in the battery (l2-volt shown). Inspect the battery once every two weeks to maintain the correct specific gravity. The specific gravity of a fully char~ed battery is 1. 255 to 1. 270 corrected to +80 F. A specific gravity reading of at least 1. 230 corrected to +80oF. Never allow the battery to fall below 1. 230. The specific gravity reading will temperature of the electrolyte. taken at any temperature other a temperature correction must is done by adding . 004 specific for every 100 above +800F. , and bJ . 004 specific gravity for every 10 vary withthe For read-ings than +800F. , be applied. This gravity subtracting below+800F. The temperatures shown indicate the approximate points at which the first ice crystals begin to appear in the solution. The solution does not freeze solid until a lower tem-perature is reached. A battery three-fourths charged is in no danger of damage from freezing. Therefore keep the battery better than three-fourths charged, especially during winter weather. If your tractor is not to be operated for some time during the winter months, it is advisable to remove the battery and store it in a cool, dry place above freezing (+32OF . ). Place the battery on a rack or bench.

Retighten in the same order, giving each bolt a fraction of 4. Place your thwnb over the spark plug a turn at a time. Continue this until all bolts opening and slowly crank the engine until an are tight. Do not screw one bolt down perfectly outward pressure is felt.
