MAINTENANCE
Tip: Check the condition of the o-ring on the battery cap
when replacing your battery. To ensure a watertight seal,
keep the o-ring lubricated with silicone grease and replace
any o-rings that appear worn or damaged. Find the
PRECISION Maintenance Tutorial video at 4iiii.com/docs.
Replacement battery covers and o-rings are available
from our online store.
