OIL BLOWING OUT OF THE MOTOR BLOW-OFF VALVE
Drain line restricted or blocked – stop work immediately.
Check the drain line hose for obvious restrictions at fittings, filters etc.
Check the drain hose for damage – look carefully as the bore of the hose can be crushed even when the
outside of the hose looks to be in good order at a casual glance.
Check the drain hose point of entry into the base machine hydraulic oil system – it is always best to run it
directly to tank.
Do not work with quick disconnects as they can cause restriction
Drain line being pressurised – check that the line is not connected to a supply line e.g. the pressure line
from a breaker circuit.
