replaced. Grind in a new carbon should be done by a professional mechanic. Letting the carbons
wear out too much, will braze out the coil connectors in the commutator. The generotr´s correct
power emission will be tested using high precision equipment. Also, the
condition of the circuit breaker (spring tension, lever bedding, breaker cam) will be inspected. The
grease cloth for the breaker cam should receive 2-3 drops of oil every 1000miles.
Further more, given the opportunity, the ignition timing will be adjusted, because it changes itself in
operation due to wear of the points. The correct position should be 4mm before TDC (Top Dead
Center of the piston).
This timing value has been identified as optimal during the extensive test phase and should not be
changed, because only this setting will ensure best performance and best gas mileage.
2.172 Battery
It is the battery´s task to supply any operational electrical equipment with energy, while the engine
is turned off. When the engine is running, it is being charged by the alternator. The amount of
charge adjusts itself depending on the battery´s energy level.
Picture 19, Battery
The Lead-battery has a maximum capacity of 8Ah (Ampere hours), assumed that the battery is
discharged at a rate of 20 hours with 5% of the nominal capacity, equaling 0,4 A.
With the outside temperature falling, the capacity of the battery secedes rapidly. This is why you
should always pay attention to the actual charging state of the battery especially in winter. Where a
battery on low charge freezes at about -15 degrees celsius (5 degrees farenheit) and possibly
breaks the battery case, there is no need to worry about freezing battery acid in a well charged
battery.
2.172.1 Battery maintenance
The battery is very important for the proper functionality of of the ignition and the lighting system.
The operative condition of your motor scooter and it´s engine is highly depending upon the
condition of the battery. Due to that fact it requiresregular attention.
In it´s first two weeks of operation, it should be recharged at an external battery charger twice,
because a new battery reaches it´s maximum capacity by and by. When in permanent operation, it
