SUSPENSION FORK BOOT:
Frequently inspect the rubber boot at the base of the headtube for
tears or cuts which could allow contamination. If the boot is dam-
aged in any way, it must be replaced immediately. Since boot re-
placement requires the suspension fork be removed from the frame,
this job should be performed only by an experienced bicycle mechan-
ic at an Authorized HeadShok Service Center. Damage to the Head-
Shok due to contamination by water or dirt will not be covered under
warranty.
HYDRAULIC CARTRIDGE OIL OR SEAL REPLACEMENT:
The oil in the HeadShok hydraulic DD15 hydraulic cartridge should
be replaced every 80 hours of riding, or at least once a year. The
seals in the cartridge require less frequent attention, and should
be replaced every two years or as needed. These procedures require
unique tools and substantial expertise and training with hydraulic
suspension systems. Therefore, they should be performed only by an
experienced mechanic at an Authorized HeadShok Service Center.
NEEDLE BEARING LUBRICATION:
The needle bearings which provide the smooth travel of the suspen-
sion in the HeadShok fork should be lubricated every three months or
60 hours of riding. This procedure requires partial disassembly of the
suspension fork, and therefore must be performed only by an experi-
enced bicycle mechanic at an Authorized HeadShok Service Center.
