Bobcat code M0909: Fuel level too low

What it means

The fuel level has dropped below the low-fuel point. Telehandlers show the same code as fuel level low.

Can I keep running?

Keep going carefully, fix soon

Usually, if the machine runs normally: finish the job carefully and fix it soon. Stop if the machine derates, overheats, loses power or the code comes with an alarm.

Check first

Park on level ground, lower the lift arms and attachment to the ground, stop the engine and remove the key.
Check the fuel level and refuel with clean diesel. No smoking or open flame near fuel.
Restart and confirm the code clears.
If the tank is full and the code stays on, check the fuel level sender connector and wiring.

Likely causes

Tank is nearly empty
Faulty fuel level sender or wiring (if the tank is actually full)

The fix

Refueling clears it. Try not to run dry: you may then need to bleed air from the fuel system (see Removing Air From the Fuel System in the O&M manual). If the code stays on with a full tank, the sender or its wiring needs work.
