Figure 3 & 3a Insert the conductor between the blades up to the cutting point

Insert the conductor between the blades, up to the desired cutting point (Fig. 3). For a running conductor, press the locking lever (1) and open the tool head (Fig 3a).

Fully retract the lower blade (3) before attempting to open the tool head. With the conductor on the lower blade (3), close the tool head and fully secure the lever (1).

Warning: Before commencing the cutting operation ensure that the lever (1) is fully secured: partial closure may damage the tool head.

Cutting Blade Advancement

Press the operating button (5) (Ref. to Fig. 3) 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 button (5) and the motor will cut out.

Warning: Make sure the blade is exactly positioned on the desired cutting point otherwise re-open the blade following instructions and reposition it.

Cable Cutting

Firmly hold the tool and operate the button (5) to gradually move the lower blade (4) to cut through the conductor.

When the cut is performed release the button (5) to ensure the maximum pressure relief valve isn’t activated.

LED Worklights

Whilst the tool is in operation, the work area is illuminated by two high luminosity LED Worklights that switch off automatically at the end of the cycle.

Blade Retraction

By operating the pressure release button (6) the ram will retract and open the lower blade.

Battery Status

Figure 4 Battery Level Indicator

Figure 4 Battery Level Indicator

The battery is equipped with LED indicators that indicate the remaining battery life at any time by pressing the adjacent button (9):

  • 4 LEDs illuminated: fully charged
  • 2 LEDs illuminated: 50 % capacity
  • 1 LED flashing: minimum charge, replace the battery

Worklights (11) illuminated combined with an alarm audible when the operating button (5) is pressed (Fig.4) is an indication that the battery voltage has dropped below a minimum safety threshold

Under these conditions the tool will not start and the battery should be replaced or recharged (80 minutes to fully recharge battery).

After each working cycle and  the extraction of the battery from the tool, an integrated battery cut-off device will operate after approximately 70 s.

The LED nearest to button (9) will then flash 5 times each 14 s approx. The battery will be reactivated when it is reintroduced into the tool and the operating button is pressed.

Using The Battery Charger

Carefully follow the instructions in the battery charger user manual.
