INSTRUCTIONS FOR USE
MARZOCCHI forks are based on an
advanced technology coming from the
company’s years long experience in the
professional mountain bike industry.
For the best results, it is advisable to
inspect and clean the area below the dust
seal and the stanchion tube after every use
and to lubricate the parts with some
silicone oil.
MARZOCCHI forks usually offer the best
performances since the very first rides.
Notwithstanding this, a short running-in
period may be necessary (5-10 hours) to
adjust the internal couplings. This
precaution will lengthen your fork’s life and
guarantee its best performances.
Changing the oil every 100 hours is
recommended.
The forks with a polished finish must be
treated periodically with polishing paste to
keep the exterior shining like new.

GENERAL REGULATIONS
· After a complete breakdown, always use
new MARZOCCHI seals when
reassembling.
· Before reassembly, wash all new and old
components and dry them with some
compressed air, making sure there are
neither breaks nor burrs.
· Never use flammable or corrosive
solvents to clean the parts as this could
damage the seals. If necessary use specific
detergents that are not corrosive, not
flammable or have a high flash point
compatible with the materials of the seals
and preferably biodegradable.
· Before reassembling, always lubricate the
parts of the fork in contact with some oil for
forks.
· Never pour lubricants, solvents or
detergents which are not completely
biodegradable in the environment; these
must be collected and kept in the relevant
special containers, then disposed of in
accordance with the regulations in force.
· Always grease the seal lips before
reassembling.
· Use only metric spanners and not
imperial. Imperial spanners may have
similar sizes to metric ones but they can
damage the bolts and screws making it
impossible to unscrew them.
· Use the right size and sort of screwdriver
to unscrew slotted or crosshead screws.
· When using a screwdriver to assemble or
dismantle metal stop rings, O-ring seals,
guide bushes or seal segments, avoid
scratching or cutting the components with
the tip of the screwdriver.
· Use only original spare parts.
· Before servicing the fork, we recommend
washing the fork thoroughly.
· Work in a clean, ordered and well-lit place.
· Carefully check there are no metal
shavings in the work area.

Warning
FITTING THE FORK ONTO THE FRAME
The fork is supplied with “A-Head Set” steer
tube to be cut according to frame size it will
be used on.
Fitting the fork onto the bike frame is a very
delicate operation that must be carried out
at one of our service centres only.
The assembling on the frame and the
adjustment of the steer tube must be
carried out following the instructions of the
steering set manufacturer.
A wrong installation can be dangerous
for the rider.
Marzocchi does not guarantee the
assembly and accepts no liability for
damage and/or accidents arising from a
wrong installation.
The steer tube must be pressed into the
crown; its replacement must be carried
out by one of our service centres using
the adequate tools.
A wrong installation of the steer tube
into the crown may cause the rider to
lose the control of the bike and lead to
serious personal injury.

Improper installation of the disk brake
system can overstress the caliper
mountings, which may break. The
installation of the brake system must be
carried out following the instructions of
the brake system manufacturer.
Improper installation can be dangerous
for the rider.

Warning
ASSEMBLING THE WHEEL ON FORKS
WITH STANDARD DROPOUTS
Install the wheel following the
instructions of the bike’s manufacturer.
A good and reliable operation of the fork
and all of the parts linked to it mainly
depend on the correct fixing of the front
wheel.
For a correct operation of the fork, install
the wheel as explained below:
Check the correct fork-wheel alignment by
fully compressing the fork a few times.
Lift the front wheel above the ground; turn
the wheel a few times to verify the correct
alignment with the disk brake.
