Operation.
Wolflite XT handlamps are operated with a 'press and release' of the sliding switch with
the switch depressed for < 1 sec. For some modes, or to switch the lamp off at any time, a
long press > 2 sec is required.
XT-50 [Duration: 3.0 hrs full / 6.0 hrs half] – [Recharge Time: 3:00]
The XT-50 has dual power light output. Press switch once for Full Power and a second
time for Half Power. Press switch again to switch the lamp off.
XT-70 / XT-75 [Duration: 6.0 hrs full / 12.0 hrs half] – [Recharge Time: 3:30]
The XT-70 / XT-75 have both Spot Beam and Flood (Wide) Beam Modes and dual power
light output. Press sprung switch once for Full Power Spot and a second press for Half
Power Spot, a third press for Full Power Flood, followed by a fourth press for Half Power
Flood. Press switch again to switch the lamp off.
If the lamps remain in any one of the spot or flood modes for > 10s, any subsequent
press, will switch the lamp off.
XT-90 [Duration: 9.0 hrs full / 18.0 hrs half] – [Recharge Time: 4:00]
The XT-90 operates as per the XT-70 above, Signal modes can be entered by pressing
and holding the switch for 2 sec. followed by a quick press of the switch to change
between signal modes. To exit, press and hold switch for 2 sec.
Deep discharge protection: circuitry will automatically switch the Handlamp off once the
battery reaches a pre-determined low voltage.
Handlamp Indication on discharge

0 LEDS (with beam flash warning)
Emergency lighting mode: The emergency lighting function switches the lamp on when a
power failure to the charger occurs.
To activate this function on a lamp, press and hold the switch for 5 sec while lamp is on
charge. (3 flashes of the spot beam will confirm emergency light mode ON) to deactivate,
repeat, (2 flashes of the spot beam will confirm emergency light mode OFF). The lamp will
remain in the mode it was set to.
Handlamp Head Assembly Replacement: (See Fig 6)
The Handlamp head assembly contains no user serviceable items.
If Handlamp fails to light or;
If no indication on the lamp is shown on charge:
A. Ensure handlamp will charge – check power indicator on charger, check the handlamp is
fully engaged in the charger and check that the charge contacts on the charger and on the
base of handlamp are clean.
B. If the charge indication works but the handlamp does not light, check that all switch parts
are present and that the switch can depress fully. (The switch assembly contains a
cylindrical magnet)
C. Contact Wolf Safety for further information
Cleaning: Use a mild soap and water and soft brush only. Do not immerse.
.
The XT-202, XT-204 and XT-206 Batteries utilise a Lithium Ion system with a life of up to
500 full charge/discharge cycles (to 70% original capacity), and incorporate an integral
encapsulated battery protection circuit.
Replace the Battery when the discharge duration is significantly shorter than the durations
required. Recharge every six months when in storage.
