– While pump is operating there is no increase in pressure on the manometer.
– Check to make sure the oil discharge lever is not pressed.
– Operate the oil discharge lever briefly several times and check if after operating this immediately
returns to the start position.
– Check to see if there is sufficient insulating oil in the pump (remove the top-up cover of the tank).
– Add insulating oil if needed (use only TOTAL DIEKAN 1640 oil).
– Although the safety valve has triggered and the maximum operating pressure has been
reached, the cable has not been completely cut.
– Move away from the zone immediately.
– Contact the electricity supply utility immediately for information.
– Operate the oil discharge lever for 60 seconds.
– Remove the head from the cable using an insulating rod.
– Accurately check the cutting head (e.g. condition of blades; fittings); possibly carry out a "free
run".
– If the electricity supply utility has not given specific instructions, move the cable cutting unit to
a dfferent point and carry out the cutting operation again.
– While the pump is functioning there is a leakage of insulating oil.
– Immediately stop pumping.
– Operate the oil discharge lever for 60 seconds until the insulating oil in the system returns to the
tank and the blades of the cutting head can open.
– Should the cable be under voltage, inform the electricity supply utility immediately.
– If the absence of voltage cannot be affirmed with absolute certainty, remove the cutting head
from the cable using an insulating rod.
On no account touch the cutting head with the hands or conductive objects!
– If the cable has to be cut even though it is under voltage, carry out the operation with another
device that is known to function correctly.
– If the oil leaks from the screwed coupling of the hose, this can be tightened.
– If the fault is not removed, the cable cutting units must be sent to Cembre to be tested and
repaired.
