The belt is adjustable by means of a swinging generator mounting. Moving the
generator away from the engine increases the belt tension while moving it towards the
engine decreases its tension. Belt adjustment is correct when it is possible to depress the
belt approximately 3/4", as shown in the illustration.
Adjustment is made by loosening cap screws and nuts (D), (E) and (F). When proper
position has been obtained, be sure to tighten screws and nuts securely.
Before installing any anti-freeze when preparing for winter operation, it is good
practice to always drain and flush the cooling system to insure unrestricted circulation.
Also carefully check all hoses and gaskets for leaks or signs of deterioration.
Avoid the use of anti-freeze solutions containing calcium salts, or other ingredients
which promote electrolytic action. Glucose and honey clog the radiator; kerosene and fuel
oil when hot, expel inflammable vapors and, therefore, solutions containing these ingredi-
ents should never be used.
The following anti-freeze table will be helpful in determining the quantity of anti-
freeze required for proper protection:
