Do not use the tool for purposes other than those intended by Cembre.

Theoperatorshouldconcentrateontheworkbeingperformedandbecarefultomaintainbalanced

working position.

Work in a clean, uncluttered area. Keep persons away from immediate work area.

Inspect the blades before each use. Do not use damaged blades.

Damaged blades can break and cause injury or damage to the tool.

Before each use, verify the integrity of the tool; replace any worn, possibly damaged or missin

parts with original Cembre spares.

Wear eye protection. Metal chips can y from blades when cutting.

Pay attention when cutting short, free pieces of steel rod or rope as they may y o dangerously,

causing injury to the operator or persons nearby.

Do not cut live cables or conductors.

The tool is unsuitable for continuous use and should be allowed to cool down following uninte

upted, successive cutting operations; for instance, having exhausted a fully charged battery in

one session, delay battery replacement for a few minutes.

Protectthe toolfromrainandmoisture.Water willdamage thetooland battery. Electro-hydraulic

tools should not be operated in pouring rain.

2. INSTRUCTIONS FOR USE

The part reference includes the following:

Hydraulic cutting tool (B-TC250YNA is tted with adapter to use Makita battery).

Li-Ion rechargeable battery (2 pcs) (model depends on the tool version).

Battery charger (model depends on the tool version).

Shoulder strap.

Carrying case.

USB cable (Ref. to § 5).

The tool can be easily carried using either the handle or the shoulder strap attached to ring (9)

(Ref. to Fig. 6).

Before starting any work, check the battery charge (Ref. to § 2.8) and recharge if necessary.

Refer to the manufacturer's instructions for the correct use of battery and battery charger.

To replace the battery, remove it by pressing the release button (7) (Ref. to Fig. 1a and 1b),

B-TC250YA: in the g. 1a press the release buttons (7) and slide the battery out unlocking it.

B-TC250YNA: in the g. 1b press the release button (7) and slide the battery out unlocking it.

Insert a charged battery by sliding it into the guides until it locks.

2.1) Head rotation

For ease of operation, the tool head can rotate through 180°, allowing the operator to work in the

most comfortable position (Ref. to Fig. 2 and 3).

Do not attempt to rotate the head when the hydraulic circuit is pressurised.

WARNING

2.2) Setting

Insert the conductor between the blades, up to the desired cutting point (Ref. to Fig. 2).

To cut short pieces of steel or ACSR ropes, it is suggested to tie or wrap rope with adhesive or

duct tape around the area to be cut and at its end (Ref. to Fig. 2), so to limit the projection of

steel fragments which could damage or hurt the operator.

For a running conductor, release the latch (4) and open the tool head.

Fully retract the lower blade (3) before attempting to open the tool head (Ref. to § 2.6).

With the conductor on the lower blade (3), close the tool head and fully secure the latch (4) (Ref.

to Fig. 3).

Before commencing the cutting operation ensure that the latch (4) is fully secured: partial

closure may damage the tool head.

2.3) Blade advancement

Operate the push-button (5) (Ref. to Fig. 2) to activate the motor-pump, the ram will gradually

move forward until the lower blade (3) touches the conductor.

To halt the advancement, release the push-button (6) and the motor will cut out.

Make sure the blade is exactly positioned on the desired cutting point otherwise re-open the

blade following instructions as per § 2.6 and reposition it.

2.4) Cutting

Firmly hold the tool and operate the push-button (5) to gradually move the lower blade (3) to cut

through the conductor.

When the cut is performed, release the push-button (5), otherwise after the maximum pressure

reliefvalve hasactivated(doubleactivation for "Y" versions)andthe motor will stopautomatically.

2.5) LED Worklights

Whilst the tool is in operation, the work area is illuminated by two high luminosity LED Worklights

that switch o automatically at the end of the cycle.

2.6) Blade retraction

By operating the pressure release button (6), the ram will retract and open the blades.

2.7) Using the battery charger

Carefully follow the instructions in the battery charger user

manual.

2.8) Battery status

The battery is equipped with LED indicators that indicate the

remaining battery life at any time by pressing the adjacent but

ton (P):

4 LEDs illuminated: fully charged

2 LEDs illuminated: 50 % capacity

1 LED flashing: minimum charge, replace the battery

Worklights (1) illuminated combined with an alarm audible when the operating button (5)

is pressed (Ref. to Fig. 6), indicate that the battery voltage has dropped below a minimum

safety threshold; under these conditions the tool will not start, and it is necessary to recharge

or replace the battery.

The approximate time to fully recharge a battery is about 80 minutes.

After each working cycle, and after the extraction of the battery from the tool, an integrated

battery cut-o device will operate after 70 s approx. Then the LED nearest to button (P) will

ash 5 times each 14 s approx. The battery will be reactivated when it is reintroduced into

the tool and the operating button is pressed.

3. MAINTENANCE

The tool is robust, completely sealed, and requires very little daily maintenance. Compliance with

the following points, should help to maintain its optimum performance:

3.1) Thorough cleaning

Dust, sand and dirt are a danger for any hydraulic device. Every day, after use, the tool must be

wiped with a clean cloth taking care to remove any residue, especially close to pivots and move-

able parts.

Do not use hydrocarbons to clean the rubber parts.

Regularly lubricate the moving parts and pivot pins of the head with a few drops of oil.

3.2) Storage case

When not in use, the tool should be stored and transported in the plastic case, to prevent damage.

The case, type VAL-P40, is suitable for storing the tool and accessories.

VAL-P40: Size 520x432x126 mm (20.5x17.0x5.0 inches). Weight 2,6 kg (5.7 lbs).

3.3) Routine maintenance

When the tool reaches the predetermined number of hours worked, it will signal that routine

maintenance is recommended.

Thetoolwillcontinuetoworkhowever15sec.afteruseanalarmcomprising3beepscombined

with illumination of the worklights will signal that its return to Cembre for service is recom-

mended (see § 7).

4. BLADE REPLACEMENT (Ref. to Fig. 5)

When changing blades, the battery must rst be removed from the tool.

After extended use, the blades may break or loose their cutting edge.

Replace the blades as follows:

Lower blade

– Release latch (4), and open the tool head completely.

– Operate the tool to advance the lower blade (3) and remove the battery.

– Eject two split pins (12) from the ram (13) to release the blade (3).

– Remove the broken blade from the ram, insert the new blade and t with two split pins.

Before closing the tool head, push the release button (6) and fully retract the lower blade,

otherwise the tool head assembly may hit and damage, the lower blade.

Upper blade

– Release latch (4), and fully open the tool head.

– Remove circlip (16) and extract the head pin (15) to release the latch.

– Remove circlip (23) and latch pin (15) to release the latch.

– Remove the latch and recover the latch spring (24).

– Using a 10 mm spanner, remove 8 nuts (22) and relevant washers (21).

– Remove 4 studs (18), releasing the broken blade (2).

– Position the new blade, insert 4 studs (18), t 8 washers (21) and light tighten 8 nuts (22).

– Insert the latch spring (24) into the spacer (19).

– Reassemble the latch (4) and fully tighten the 8 nuts (22).

– Fit the head assembly to the head support using the pin (14) and circlip (16).
