10 Troubleshooting
10.1 Hydraulic breaker does not start
Cause Remedy By

mixed up. Check that the connections of the pressure and tank
hoses are correct.See section "Hoses and connection". Carrier driver
Shut off valve in pressure and/or
tank hoses is closed. Check the shut off valve and open it. Carrier driver
Defective couplings blocking
