Instructions for
mounting/removing
tyres with HELP and
PRESS ARM
ed. 11/2005 cod. 3015761
Preliminary remarks: HELP and PRESS ARM are accessories fit to be installed on
S222 – S225 – S224 – S231 – (S232).
PRESS ARM only can be installed on S112F.
Their combined use is essential with “zero pressure” tyres.
The use of PRESS ARM is essential on low-profile tyres (from /45 to /30).
They are recommended on any kind of tyres.
Between the two devices, the PRESS ARM is the more versatile one.

REMOVAL

Set the wheel on turntable, pressing tyre from over the jaws, and
lock the rim paying attention it doesn’t slip out of the jaws (this
operation might turn out difficult or even impossible).
Use the PRESS ARM to push the wheel downward so making its
clamping easier.
Correct clamping
Manual procedure
Assisted procedure

In case the rim to be removed has an “overturned” groove, use the
accessory shown above (WHEEL PRESSING CONE, part no.
9214251) to keep the tyre pushed on the jaws, so locking the rim.
In case the tyre bead slips back again into its seat, manually help
the tool positioning, acting a bit on the hexagonal arm (the
operation might turn out difficult or even impossible)
Manual procedure
Assisted procedure

HELP roller (if available) can be used for pushing the tyre in a way
to correctly set the tool on the rim without any effort.
PRESS ARM press pad can be used for pushing the tyre in a way
to correctly set the tool on the rim without any effort.
Assisted procedure
Assisted procedure

Use the PRESS ARM press pad to keep the tyre pushed while
inserting the lever between tyre and tool.
Push the tyre downwards, by hand, to let the bead lifting lever enter
the gap between tyre and tool (this operation might turn out difficult
or even impossible).
Manual procedure
Assisted procedure

Use the HELP roller (if available) to
push the tyre in a way to correctly
set the bead lifting lever between
tyre and tool.
To remove first bead from rim it is necessary
to push it downwards, at tool opposite side,
to position it at the rim groove level (this
operation might turn out difficult or even
impossible).
Manual procedure
Assisted procedure

Use the PRESS ARM disk to lift the tyre lower part from left side,
help yourselves by hand to also lift it from right side, in a way to
facilitate the insertion of the lever and complete detachment
operation.
Use the PRESS ARM press pad to push the tyre in a
way to bring the bead (tool opposite side) into the rim
groove and to make its detachment easier.
Manual procedure
Assisted procedure
Assisted procedure

If both devices are installed, use both disks to lift the tyre from both
right and left side.
If HELP is available, use its roller to lift the lower bead over tyre
edge to allow removal operation without lever.

Use the HELP press pad (if available) to push the tyre in a way to
grease the rim inner side so facilitating the detachment.

Tyre MOUNTING
ATTENTION: being mounting operation on “zero pressure” tyres impossible, and on low
profile tyres (from /45 to /30) rather difficult to be performed by hand, the photographic
sequence related to manual procedures is not available in next section.

Set the PRESS ARM pad at right of the tool and, by hand, push the
tyre bead section next to the tool while turning the turntable
clockwise, so proceeding mounting the tyre.
Tyre mounted with PRESS ARM assisted procedure.

If both HELP and PRESS ARM are available, set the HELP roller
and the PRESS ARM pad as shown above.
Make sure that the HELP roller and the PRESS ARM pad are at the
same height and at rim groove level. Act on rotation control pedal to
proceed mounting the tyre.

If the tyre bead tends to set itself as shown above, the pad will also
tend to move upwards owing to the tyre strength. In such case,
lower the pad to bring the bead back to turntable parallel position.
HELP roller position stays unchanged.
Bring the tyre bead back to correct position by acting on the pad.

Move roller and pad up and down as to keep the tyre bead C
levelled with rim groove D, all through the rotation.
