Troubleshooting and Maintenance
 Disassembling the sealed head can damage the flashlight and voids the warranty.
 Wurkkos Ltd. recommends using high-quality brand batteries. Damage by defective
batteries void the warranty.
 Remove the battery if the flashlight will not be used for an extended period of time.
 To prevent self-discharge or accidental activation during storage or transportation,
unscrew the tailcap by half a turn or remove battery.
 Every 6 months threads should be wiped with a clean cloth followed by a thin layer of
silicone grease.
 To maintain a proper level of waterproofness, replace worn-out o-rings with an approved
spare (2 pieces are shipped with initial order).
Troubleshooting: Clean battery contacts regularly as dirty contacts may impair the
performance of the flashlight. If you experience problems (flicker, shine intermittently or
failure to turn on) the following root causes and solutions should be tried:
Reason A: The battery needs replacement (Battery voltage is below 2.6V).
Solution: Replace battery with an approved type of fully charged battery.
Reason B: Threads, PCB board contact or other contacts are dirty.
Solutions: Please clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods do not work please refer to the warranty policy before contacting your
authorized distributor.
Please contact us if you have any questions. If your product is defective please contact us for
refund or replacement within warranty period.
