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.
