Maintenance and Troubleshooting
Operating Maintenance Meter
See Figure 4-1 . The maintenance meter monitors accumu-
lated running time, time until engine oil needs to be
changed, and time until lubrication is recommended. Press-
ing function button (A) cycles through the meter functions.
Figure 4-1. Operating Maintenance Meter
After 25 hours of running time, the meter will automati-
cally blink as a signal for an oil change. It will continue to
blink for a two hour period of accumulated running time.
The next alert will automatically appear in 25 hours.
If the RPM indication is not responding to changes in
engine speed, check the connections at the meter and verify
the meter wire is wrapped tightly around the spark plug wire.
