ML-2 INFORMATION
The ML-2 headpiece is made up of
the lamp-housing, which contains the
following parts:
— Bezel (cover)
— Lens
— Gasket
— Focusing Knob
— Two Filament Bulb
— Reflector
— Hexagonal Key Lock
— Stainless steel clip
— Charging circuit connection
— Switch knob
The bulb is a two filament bulb which
permits the use of a safety filament if
the primary filament burns out. The
switch knob selects either filament.
The gasket helps seal out dust and
moisture from the headpiece.
The focusing knob adjusts the focus
to a small spot or flood light. Once
focused, it does not require further
focusing until a new bulb is installed.
The reflector makes maximum use of
light output. The hexagonal key lock
locks the headpiece to ensure that the
settings are not changed. The stain-
less steel clip attaches the headpiece
to the miner’s cap.
USING ML-2 CAP LAMP SYSTEM
The on-off switch knob is a 3 position
switch, located on the headpiece. To
operate the lamp:
1. Turn the switch knob clockwise or
counterclockwise to turn on the pri-
mary filament. The primary filament
provides the brightest beam of light.
2. Turn focusing knob to adjust the
light beam to a spot or wide beam.
3. After use, turn the switch knob
until the bulb is off.
Note
In the case of the primary filament
burning out, the safety filament may
be switched on by continuing to turn
the switch knob. Check the bulb to be
sure both filaments are in working
order before use.
