Engine RPM and Hours
0004
The engine hours are displayed only on ignition start-up. Once the engine has been cranked and the engine has been running
for 5 seconds, the engine hours are extinguished and the real-time rpm are displayed. The display for the engine hours is a
4-digit number (Figure 33, Item 3). When the engine hours are being displayed, the 5-digit number (the fifth digit is tenths) is
followed by the text "Hours." When the real-time rpm are being displayed, the 4-digit number will be followed by the text
"RPM."
The timer symbol (Figure 33, Item 2) will flash intermittently. This is just a means of showing that the engine hours are being
recorded.
