The quality of tone and length of service received from Ford horns depends entirely on the care they receive.

To produce the most effective tone, it is necessary that the armature revolve at a high rate of speed. This speed is possible only when bearings are properly oiled, and the commutator and brushes are kept clean.

LUBRICATION

Once a month, remove motor cover located at rear of horn and place a few drops of oil in groove at each end of the armature shaft. Use light fine oil.

CARE

To clean the commutator, set the motor in motion by pressing the horn button. while motor is revolving, hold a piece of fine sand- paper against commutator until commutator is clean.

Next, with a small piece of wood, clean the gaps between the commutator segments. Do not use metal when cleaning gaps.

When turned with the fingers, the armature should revolve freely. Should it fail to operate, examine the battery, the wiring, and the horn button.

ADJUSTMENT

Turning the adjusting screw regulates the tone.

Turning the screw to the right tightens the adjustment. Turning to the left loosens it. Regulate the adjustment until the desired tone is obtained.
