Battery Installation
Unscrew the tailcap and insert new batteries. Replace
tailcap and depress tailcap pushbutton switch to test.
If light fails to function the tailcap may be in the lock-
out position (excluding the G2 Nitrolon®, which does
not feature a lock-out tailcap). Rotate the tailcap
clockwise until momentary activation is possible.
Light Activation
For momentary light, press the tailcap pushbutton
switch. The light will stay on as long as the
pushbutton is pressed. Rotate the tailcap clockwise
for constant-on light.
Lock-out Tailcap
(pat. #
6222138
)
From the momentary-on position, rotate the tailcap
approximately 180º counter-clockwise. The lock-
out position prevents accidental activation during
storage or transport.
Maintenance
At least twice yearly, clean threads and O-rings with
clean cloth and apply a thin coat of silicone-based
grease or lubricant to both. If flashlight is used in
wet environment, lubricate O-rings frequently to
maintain watertight seal. After prolonged exposure
to moisture, the bezel, lamp, and batteries should be
removed, inspected, and dried if necessary.
Lamp Replacement
Rotate bezel (head) counter-clockwise to remove.
Remove lamp/reflector assembly and replace with
recommended assembly.

CAUTION
CAUTION
SureFire flashlights produce substantial heat during
operation. Do not leave activated flashlight unattended.
Do not set activated flashlight face (lens) down. Do not
place activated flashlight against combustible material or
material that could be damaged by heat. Do not hold
bezel or lens of activated flashlight against any portion of
human body. Keep away from children.
Ensure that the flashlight cannot be turned on when
stored or being transported. If the lamp is activated while
in a case or other container, the lamp could overheat and
cause damage to surrounding materials. For models not
equipped with a lock-out feature, remove the batteries or
unscrew the bezel enough to prevent accidental activation.
Do not touch a hot lamp assembly. Allow it to cool before
handling. Avoid touching reflector surface. SureFire lamp
assemblies are pressurized. Always wear safety glasses
when handling.
