– Application range: cable cutting safety heads can only be used to cut Copper and Aluminum
cables where the absence of voltage cannot be guaranteed.
Hydraulic cable cutting safety heads must be used only with insulated flexible hoses and
hydraulic pumps containing insulating oil.
Insulating oil is a special hydraulic oil with properties which insulate the pump from the
cutting head.
3. INSTRUCTIONS FOR USE
Cable cutting units (head and pump) must be used as described herein and always observing
working procedures estabilised by the responsible power utility.
3.1) Preparation
Only remove the cutting head from its case at the work place.
TC065Y-SC-KV and TC085Y-KV: mount the support handle (4) on the head by screwing it onto the
threaded pin (14); at the end of the work, remove the handle before storing the head in its case.

3.2) Connecting the insulated flexible hose (Ref. to Fig. 4)
Fully unravel the insulated flexible hose.
Remove caps and connect the female coupler of the insulated
flexible hose to the male coupler (11) of the hydraulic head to
be used.
Before using the pump always check the
integrity of the insulated flexible hose
and the quick couplers.
Connectthemalecouplerof the
insulated flexible hose to
the female coupler
of the pump.

3.3) Grounding the cutting head
Safety cutting heads are provided with a grounding socket (1).
To ground the cutting head, proceed as follows:
• Using a grounding wire with lug termination
Unscrew knob (2) from the grounding socket (1) of the head.
Connect the terminal of the grounding wire to the socket (1)
using the knob (2), fasten the knob tightly.
Fully unwind the grounding wire and connect it to a grounding system using the clamp.

Once the blades of the cutting head are around the cable to be cut, stabilise the head in position
(e.g. by pressing the cutting head against the ground); when used in the“man-hole”we recommend
the usage of SS-TCY support strap (Ref. to § 6) in order to support the head in the horizotal stable
position.

• Using a grounding wire with ball & socket termination
Unscrew knob (2) from the grounding socket
(1).
Screw the grounding pin (15) tightly into the
socket (1) (1/2”-13 UNC thread).
Fully unwind the grounding wire and connect
it by the clamps to the grounding pin (15) and
to the grounding system using the clamps.
3.4) Positioning the cutting head
The cutting head must be manually positioned
around the cable to be cut based on the diameter
of the cable (Ref. to § 1).
TC065Y-SC-KV and TC096Y-KV: insert the cable
between the blades, at the desired cutting point.
TC050Y-KV and TC085Y-KV: release latch (5) to open the blades.
Insert the cable, close the head and fully secure the latch (5).
Ensure that the head is fully secured: partial closure may damage the head.
TC120Y-KV: Extract the locking pin (13) to open the blades. Insert the cable, close the head and
fully secure the locking pin (13).
Ensure that the head is fully secured: partial closure may damage the head.
Make sure the blades are exactly positioned on the desired cutting point.

3.5) Cutting
Cutting operations strictly follow the safety and working procedures established by the
responsible power utility.
Fully unravel the insulated flexible hose to provide a safe working distance.
Operate the pump to advance the blades and progressively cut the cable.
At the end of the operation open the blades using the oil release control of the pump.
Access the cutting area and remove the cutting head from the cable using the support grip
provided.
3.6) Unintentional cutting of live cable
Following a short circuit, contact the electricity power utility immediately for information.
Toaccessthecuttingareaandremovethecuttinghead,strictlyfollowthesafetyandworking
procedures established by the responsible power utility.
4. STORAGE AND TRANSPORTATION
Each Cembre cable cutting safety head is pre-
cisely constructed and supplied in a robust steel
case (canvas bag for TC050Y-KV) for protection
of individual components from damage and for
transportation to the work place.
Only remove a cable cutting head- from its case
at the work place.
TC065Y-SC-KVandTC085Y-KV:removethehandle
(4) before storing the head in its case.
5. CARE AND MAINTENANCE
The Cembrecable cutting safety heads are designed for on site use and thanks to its construction
characteristics it is a technical and robust operating device.
To guarantee the reliability the Cembre cutting heads it is recommended to:
After every use, remove dirt from the cutting head, cylinder, blades
and seals using a brush dipped in a liquid detergent. Dry the area carefully.
Carefully clean the quick couplers and their protective caps each time the unit is used.
Periodically, lubricate blade pivots with some drops of oil.
Always store and transport the cutting head in its case.
5.1) Replacement of the automatic coupler
To replace the automatic coupler proceed as follows:
Remove the old coupler and carefully clean the thread of the head to remove the old sealant.
ApplyTeflon tape to the thread, fit the new automatic coupler (type I38-M) and tighten to 30 Nm
(22 lbf ft).

6. TSS-TCY SUPPORT STRAP (purchase separately)
Thesupport strapallowstheheadtohang securely
from a suitable support e.g when cutting wall
mounted cable inside “man-holes”.
Connect the strap end hooks to the hanging
points (10) of the head.
Securely wrap the strap around a stable sup-
port above the head and latch it using the ring
(17).
Set the length of the strap by means of the
buckle (16)soto support the headin horizontal
position.
