Supply three or four drops (no more) of engine oil to each oil cup "A" and "B" every 1000 miles. Do not attempt to supply more oil as it may interfere with the functioning of the generator.
Distributor
Fill distributor base with oil at cup "C" every 2000 miles. Coat rotor cam "A" with a thin film of vaseline every 2000 miles. Apply one drop (no more) of light oil to breaker arm pivot "B" every 2000 miles. Wipe excess oil and clean distributor head, removing oil or dust before returning to position. Be sure each high-tension terminal and wire on distributor head is pushed as far into its socket as it will go.
Fan
Fill fan shaft bearing with engine oil at oil cup "A" every 1000 miles. It is very important that the fan shaft has plenty of lubrication at all times.
