only two sizes are required and an extra one of each, also extra
fuse, will be found in the tool equipment.

The small tube lamp bulbs may be replaced by unscrewing
the cap, but in so doing care must be exercised not to turn the
whole lamp, as this will twist the wire and cause a short circuit.
Starter Motor.
Is strapped firmly to the crank case. It will be well to see
that the screws are, held tightly in place occasionally. This is
simply a powerful series-wound motor having armature and shaft
which, with the gear on the end, can slide endwise. Normally the
motor is disengaged, but when the starter pedal is partially depressed
the current flows through a resistance to field and armature,
causing the armature to be "sucked" toward the front (of
the car), and also to be turned slightly. This causes the gear to
engage with the large fly-wheel gear. Then when the starter
pedal is fully depressed the full battery current causes the motor
to rotate the engine. As soon as the gasoline engine fires, the
counter torque set up in the electric motor causes the gear to slip
out of mesh. Then the starter pedal should be promptly released.
The motor will require a little oil in the oilers and the commutator.
and brushes might need cleaning in time. But this
should be done at a Bosch station. The starter switch will require
only a little oil about the stein occasionally.

Ground Fuse.
If lamps or horn will not operate except when engine is running,
it is a sign that the ground fuse on the right forward side
of dash under the hood has blown out. If you cannot locate any
short circuit, replace the fuse. If this second fuse burns out it is
a sure sign of a short circuit and the condition should be reported
to Bosch or Marmon representatives at once. It will not damage
the system to use the lamp and horn while running, but tin' battery
will soon run down, as it cannot be charged, so do not delay
having the matter attended to at once.
Horn.
Should have attention mentioned in special direction book
supplied with each instrument.

Storage Battery.
On many cars this important member is robbed of its possible
life of usefulness; it is permitted to sicken and die simply through
failure to receive the nourishment essential to its life. The few
necessary precautions are outlined below.
First, battery fluid covering the plates 4 as necessary to your
battery as oil to your motor. "Boiling" and evaporating constantly
lower the fluid level, which must regularly be brought up
to the top of the plates. Never add any fluid except pure distilled
