2.4 Machine Data
3.1 Recommended Fuel
The engine requires regular grade unleaded gasoline, 91 Octane or higher. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage the fuel system. Consult engine
owner's manual for complete fuel specifications.
3.2 Low Oil Sensor
The low oil sensor is located inside the oil reservoir. Its primary job is to measure the amount
of oil inside the engine prior to the engine being started. If the oil is low, the sensor will
trigger and it will not be possible to start the engine.
NOTE: The low oil sensor may trigger if the saw is in the upright position. The
upright angle of the machine can cause the oil the fall below the sensor and trigger
it. Before starting the engine, check that the oil level is raised above the sensor
and/or the machine is lowered to allow the low oil sensor to get an accurate oil level
reading.
