FEATURES

OIL PRESSURE SENSING SYSTEM

This model is equipped with an oil pressure sensing system. When the oil pressure drops, the rpm
limiter is activated, and the engine rpm is reduced, or the engine is shut off, if necessary.
If the oil pressure is incorrect upon starting the engine
1. "OP-LO" appears and the oil level/pressure warning indicator
play.
2. When the two items, above, are displayed, they indicate the rpm limiter is in operation; the rpm is
reduced to less than or equal to the clutch engagement rpm, even though the throttle is open. If
the incorrect oil pressure persists, the engine stops automatically after approximately one
minute.
3. When the oil pressure stabilizes to the correct level, the limiter is automatically canceled as long
as the throttle is not operated and then "OP-LO" disappears and the oil level/pressure warning
indicator goes off.
4. Note that it may take a few seconds for the oil pressure to rise to the optimum level after the
engine is started, even in normal conditions. If the meter display described in (1.) is no longer
displayed after a few seconds, this indicates that everything is normal.
TIP
When disassembling the engine, replacing the engine oil or oil filter, etc., if the oil is drained entirely
from the piping, there may be delay before the oil pressure rises.
