TAXIING
When taxiing, it is important that speed and use of brakes be held to a
minimum and that all controls be utilized, refer to Figure 4-2, Taxiing
Diagram, to maintain directional control and balance.
Taxiing over loose gravel or cinders should be done at low engine
speed to avoid abrasion and stone damage to the propeller tips.
The LOW VOLTS annunciator may come on when the
engine is operated at low RPM with a high load on the
electrical system. If this is the case, the LOW VOLTS
annunciator will go off when the engine is run at higher
RPM to provide greater alternator system output. Verify that
the M BATT AMPS indication shows positive (charging)
current at the higher RPM.
