Before Use
Charge battery before first use. To prevent accidental discharge of the battery in transit, the switch is
locked in the OFF position.
To Lock/Unlock the Lamp
The stainless steel lock screw in front of the handle interlocks with the operating switch. Screw anti-clockwise
to lock the lamp enclosure and release the operating switch. The lock key provided must be kept in a
non-hazardous area.
WARNING: The Lock Screw bush can be dislodged if overtightened. Switch ‘OFF’ before
screwing the Lock Screw down.
To Operate and Dismantle the Switch
The switch operates transversely, as indicated on the approval label. It consists of a magnet, a plastic
housing and a cap. To replace, the old cap is prised off and the housing removed. The new switch
housing/magnet is fitted to the body before the cap is ‘snapped’ in place.
To Open the Lamp
Unlock as above, unscrew the lens ring from the body to gain access to all internal parts.
To Replace the Bulb
The bulb (3.6 Volts, 1.0 Amp) is retained by the screwed centre contact at the back of the reflector.
