Condividi
Applies to: Bobcat E19, E35, 335 and other compact excavators
Symptoms
- Engine runs but nothing moves
- Tracks and boom won't respond

Why it happens
The left console or lockout lever cuts pilot pressure when raised. A faulty lockout switch or solenoid, or low pilot pressure, leaves all controls dead.
How to fix it
- Lower the console or lockout lever fully.
- Check the lockout switch and solenoid for power.
- Check hydraulic fluid level and the pilot filter.
- Test pilot pressure per the manual.
Tools and parts
- Multimeter
- Pilot filter
- Pressure gauge
