What to do if the Epiroc ER-L drum does not turn or is blocked?
- FfsandersAug 12, 2025
If the Epiroc Cutter drum does not turn or is blocked, it may be due to cutting material trapped between the cutter drum and the drive. To resolve this, shut down the machine, depressurize it, and safeguard against a restart. Then, remove the trapped cutting material and allow the cutter to run in reverse briefly. Other potential causes include low hydraulic pump pressure (increase pressure via the excess pressure valve), no oil pressure (check hydraulic pump and valves), a check valve installed inverted (install it as per hydraulic installation plan version 1), or blocked hydraulic couplings/excavator valve (check couplings and open the excavator valve).
