Tachometer
e tachometer indicates the approximate speed of the engine in
revolutions per minute. e tachometer allows you to monitor the
engine speed so you can be sure not to exceed the recommended
limits described in your engine owner's manual. Some tachometers
feature an hour meter, which is useful to time your maintenance
needs. Remember that anytime the ignition switch is in the on
position the tachometer is adding hours or parts of hours to the
hour meter. Bottom line is you should only have the ignition key in
the on position when the engine is running.
