1. GENERAL CHARACTERISTICS
(1) Directive 2006/42/EC, annexe 1, point 1.7.4.2 letter u
LpA = weighted continuous acoustic pressure level equivalent.
LpCPeak = maximum value of the weighted acoustic displacement pressure at the work place.
LWA = acoustic power level emitted by the machine.
(2) Directive 2006/42/EC, annexe 1, point 2.2.1.1
Weighted root mean square in frequency of the acceleration the upper limbs are exposed to for each biodynamic
reference axis. Tests carried out in compliance with the indications contained in EN ISO 5349-1/2 Standard and under
operating conditions much more severe than those normally found.

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 missing
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 uninter-
rupted, successive cutting operations; for instance, having exhausted a fully charged battery in
one session, delay battery replacement for a few minutes.
Protect thetoolfrom rainand moisture.Water willdamagethe tooland battery. Electro-hydraulic
tools should not be operated in pouring rain.
The part reference includes the following:
Hydraulic cutting tool (B-TC550NA 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).
2. INSTRUCTIONS FOR USE
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 § 2.7) 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-TC550A: in the g. 1a press the release button (7) and slide the battery out unlocking it.
B-TC550NA: in the g. 1b press the release buttons (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, remove the locking pin (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 insert the locking pin (4)
(Ref. to Fig. 3).
Before commencing the cutting operation ensure that the pin (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
relief valve has activated the motor will stop automatically.
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) 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)illuminatedcombinedwithanalarmaudible
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.
P

8
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.
2.8) Using the battery charger
Carefully follow the instructions in the battery charger user manual.
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.
The tool will continue to work however 15 sec. after use an alarm comprising 3 beeps com-
bined with illumination of the worklights will signal that its return to Cembre for service is
recommended (see § 6).
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
– Remove locking pin (2), and open the tool head completely.
– Operate the tool to advance the lower blade (4) and remove the battery.
– Eject two split pins (12) from the ram (13) to release the blade (4).
– 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
– With the lower blade (3) fully retracted, the tool head closed and the locking pin (4) fully secured,
hold the head by the blade spacer (15) in a bench vice with screws (16) facing upwords.

9
– With an 6 mm allen key, unscrew 4 screws (16), remove the two holding plates (17) and the upper
blade (2).
– Insert the new blade, noting the position of the cutting edge bevel.
– Fit the 2 holding plates (17) and secure with 4 screws (16) with relevant washer (18).
