Warning: Please do not mix batteries of different brands, size, capacity or type. Doing so
may cause damage to the flashlight or the batteries being used.
*18650 /16340 Li-ion batteries are powerful cells designed for commercial applications
and must be treated with caution and handled with care. Quality batteries with circuit
protection will reduce the potential risk for combustion or explosion but cell damage or
short-circuiting are potential risks the user assumes.
Battery Replacement
Unscrew the tail cap to insert the batteries with the anode side (+) toward the light's
head, then align the threads and screw the tail cap back on.
Usage and Maintenance
Please don't disassemble the sealed head, doing so can cause damage to the
flashlight and will void the warranty.
We recommend the use of high quality battery. If the flashlight is not to be used for an
extended period, remove the battery, or the flashlight could be damaged by electrolyte
leakage or battery explosion.
Due to the momentary-on tactical switch, the flashlight may be accidentally activated
when stored, transported or placed in a pocket. Unscrew the tail cap one-half turn or take
out the battery to avoid unwanted operation.
The o-ring may be worn out after using for a long time. If this happens, please replace
the o-ring with a new one to keep the flashlight properly sealed against water.
Please clean the contacts of your light from time to time, especially if the light flickers
or doesn't light up. There may be several reasons for a flickering or not working light:
Reason A: The battery needs replacing.
