What it means

Can I keep running?

Check first

Park on level ground, lower the lift arms and attachment to the ground, stop the engine and remove the key.
Relieve auxiliary hydraulic pressure as the O&M manual describes and disconnect the attachment.
Inspect the high-flow solenoid connector and wiring.
Restart and see if the code comes back. If it does, stop and call your Bobcat dealer.
