Frequently Asked Questions - HTTC0851 Cembre

What types of cables can the HTTC0851 cut?

The HTTC0851 is designed to cut copper or aluminum cables, as well as telephone cables. It is not suitable for steel, almelec, or aluminum-steel cables.

How to change the lower blade?

Open the upper blade, operate the moving arm to advance the lower blade, then remove the fixing pin with a screwdriver. Insert the new blade and replace the pin. Before closing the upper blade, release the oil pressure so that the lower blade fully retracts.

How to bleed air bubbles from the hydraulic circuit?

Place the tool vertically in a vise, remove screw (67) and cap (01) from the reservoir. Operate the moving arm 3 to 4 times to advance the piston, then release the pressure by compressing the pin (75). Repeat 5 times until all air is expelled. Then close the reservoir.

What oil to use and how to top up?

Use only new oil of type ENI ARNICA 32, SHELL TELLUS OIL TX 32 or equivalent. To top up, remove the reservoir cap and fill it completely. Check the level every 6 months.

How to use the tool to cut a cable?

Place the cable between the blades, close the upper blade and lock it. Turn the main arm to the work position, then operate the moving arm to bring the blades into contact and continue until the cut is complete. After cutting, set the arm to decompression to open the blades.

What to do in case of tool malfunction?

Contact your Cembre Regional Agent or send the device to the nearest Service Center. Attach a copy of the Test Certificate or fill out the form available on the Cembre website in the ASSISTANCE section.

How to store the tool after use?

Lower the piston completely to the decompression position, keep the arms closed and turn the main arm to the rest position to lock the moving arm. Store the tool in its case to protect it from shocks and dust.

Can the cutting head be rotated?

Yes, the head rotates 180° relative to the body, allowing work in the best position. Caution: do not force rotation when the hydraulic circuit is under pressure.

What are the maintenance precautions?

Clean the tool daily with a clean cloth, especially the moving parts. Protect it from dust, sand, and mud. Check the oil level every 6 months and bleed if necessary.

Where to find spare parts and how to order them?

Spare parts are listed in the manual (figure 6). To order, indicate the item code number, designation, tool type, and serial number. Cembre recommends replacing parts marked with a ★ (spare parts kit).

2. RETURN TO Cembre FOR OVERHAUL

In the case of a breakdown contact our Area Agent who will advise you on the problem and give you the necessary instructions on how to dispatch the tool to our nearest service Centre; if possible, attach a copy of the Test Certificate supplied by Cembre together with the tool or fill in and attach the form available in the "ASSISTANCE" section of the Cembre website.

3. INSTRUCTIONS FOR USE (Ref. to Fig. 1 and 2)

3.1) Setting

With the tool is in rest position □ operate as follows:

- Insert the conductor between the blades at the desired cutting point.

For a running conductor, press latch (33) and open the upper blade assembly.

Warning: the opening of upper blade must be done when the tool is in rest position, lower blade completely retracted.

- With the conductor on the lower blade (25), close the upper blade assembly and secure the latch (33).

Check carefully that latch is firmly engaged before starting to cut.

3.2) Blade advancement

- Rotate clockwise main handle (04), to release position thus releasing the moveable handle (59). Hold tool by both handles during the cutting operation.

- Rotate main handle to operating position

- Operate moveable handle (59) for lower blade advancement. This first stage rapidly closes the lower blade (25) to the conductor. Make sure that blades are exactly positioned on desired cutting point, otherwise re-open blades following instructions as per § 3.4 and position the conductor again.

3.3) Cutting

- Continue operating the moveable handle, the lower blade advances gradually until the conductor is fully cut.

The tool is designed for cutting copper, aluminium and telephone cables: do not attempt to cut steel or ACSR conductors.

3.4) Blade retraction

- Rotate main handle clockwise to release position

Completely close handles and the lower blade will retract.

3.5) Rest setting

- Completely retract the ram as § 3.4.

- Close handles and rotate main handle to rest position ▷ ▷ ▷; the moveable handle will be locked.

- Store the tool in the plastic case.

3.6) Blade replacement (Ref. to Fig. 2)

After extended use, the blades may lose their cutting edge.

Replace the blades as follows:

3.6.1) Lower blade:

• Press latch (33) and open upper blade assembly (27).
• Pump the moveable handle (59) to make the lower blade (25) advance until fixing pin (87) is visible on ram.
• Remove fixing pin (87) and remove the lower blade (25).
• Insert new blade and secure with fixing pin (87).

Warning: before closing the upper blade assembly, release the oil pressure and retract the lower blade, otherwise the blade may hit the upper blade edge and damage it.

3.6.2) Upper blade:

• Press latch (33) and open upper blade assembly (27).
• Remove circlip (93) and pivot (92).
• By an hexagonal 13 mm, undo M8 nuts (94) and remove two studs (97), blade guide (95) blade spacer (96) and upper blade (27), noting the order of assembly.
• Fitting the new blade is a reversal of the above.

4. WARNING

The tool is robust and requires very little daily maintenance.

Compliance with the following points, should help to maintain the optimum performance of the tool:

4.1) Accurate cleaning

Dust, sand and dirt are a danger for any hydraulic device.

Every day, after use, the tool must be cleaned with a clean cloth, taking care to remove any residual, especially close to pivots and moveable parts.

4.2) Storage (Ref. to Fig. 3)

When not in use, the tool should be stored and transported in the plastic case, to prevent damage. These plastic case VAL-P7, is dimensioned 727x202x115 mm (28.6x8x4.5 in.) and weights 1,3 kg (2.9 lbs).

4.3) Head rotation

For ease of operation, the tool head can rotate through 180^ .

Warning: Do not attempt to turn the head if the hydraulic circuit is pressurised.

5. MAINTENANCE (Ref. to Fig. 4 and 5)

Air in the hydraulic circuit may affect the performance of the tool; e.g: no lower blade advancement, slow advancement of the lower die; lower blade pulsating.

In this case proceed as follows:

5.1) To purge air bubbles from hydraulic circuit

a - Hold tool upright position in a vice with handles open (Fig. 4).
b – By an hexagonal 2,5 mm key, remove screw (67) and main handle (04) to expose oil reservoir (03).
c - Remove reservoir cap (01).
d - Operate three or four times the moveable handle (59), to advanced the ram (39).
e – Depress pressure release pin (75) until ram is fully retracted.
f - Repeat points (d - e) at least five times, to ensure all air bubbles in the hydraulic circuit are into the reservoir.
g – Remove all air from reservoir.
If the oil level is low, top up as directed in § 5.2.
h - Fit reservoir cap (01).
i - Assemble main handle (04) and holding screw (67).

If the tool continues to malfunction return the tool for service/repair as detailed in § 2.

5.2) Oil top up

Every six months check the oil level in the reservoir. If necessary, top up the oil level to the top lip of the reservoir and remove all air from reservoir, see § 5.1, points a, b, c and e, finally, complete with operations h and i.

Always use clean recommended oil, see § 1.

Do not use old or recycled oil.

Do not use hydraulic brake fluid.

Upon its replacement, dispose of used oil strictly conforming with what prescribed by the relevant norms specifically applying.
