Warnings and legal notes
Before incorporating the partly completed machinery, we recom-
mend consulting this chapter carefully, in addition to the assembly
manual supplied with the individual modules. The information con-
tained in this chapter and in the manuals for the individual modules,
is provided by highly qualified and certified personnel, possessing
adequate competence in incorporating the partly completed ma-
chinery.
Avoid damage. Do not operate with inadequate tools
Precaution in installation and handling operations. Signifi-
cantly heavy equipment.
When handling the axis or system of axes, always make sure
that the support or anchoring surfaces do not leave room
for bending.
In order to stabilize the axis or system of axes, before han-
dling it is mandatory to securely block the mobile parts.
When moving axes with vertical translation (Z AXES) or
combination systems (horizontal X and/or more than one
vertical Z), it is mandatory to use the vertical movement to
put all of the axes at the corresponding lower limit switch.
Warning: moving parts. Do not leave objectson the axis
Do not overload. Do not subject to torsion stress.
Do not leave exposed to atmospheric agents.
Special installations: check the depth of the threads on
moving elements
Make sure that the system has been installed on a level
floor surface.
In use, accurately comply with the specific performance
values declared in the catalog or, in particular cases, the
load and dynamic performance characteristics requested
in the phase prior to design.
Before mounting the motor on the gearbox, it is advisable to
perform a pre-test of the motor itself, without connection to
the gear unit. The testing of this component was not carried
out by the manufacturer of the machine. It will therefore be
the responsibility of the customer of Rollon to perform the
testing of the same, in order to verify its correct operation.
For modules or parts of modular systems with vertical
movement (Z axis), it is mandatory to mount self-braking
motors to neutralize the risk of the axis dropping.
The images in this manual are to be considered merely an
indication and not binding; therefore, the supply received
could be different from the images contained in this man-
ual, and Rollon S.p.A has deemed it useful to insert only
one example.
Systems supplied by Rollon S.p.A. were not designed/en-
visaged to operate in ATEX environments.
The manufacturer cannot be considered responsible for any
consequences derived from improper use or any use other
than the purpose the axis or system of axes was designed
for, or derived from failure to comply, during incorporation
phases, with the rules of Good Technique and with what is
indicated in this manual.

facilities where the only movement possible is manual movement
(for example: motors or reduction gears, cartesian axes movements
that are not manually operated, safety brakes, stopper cylinders,
mechanical or induction sensors, decelerators, mechanical limit
switches, pneumatic cylinders, etc.). The partly completed machine
must not be commissioned until the final machine, in which it is to
be incorporated, has been declared compliant, if necessary, with the
instructions in Machinery Directive 2006/42/CE.
IMPORTANT!
All screws used for installing ROLLON modules have self-
locking washers or semi-permanent threadlock fluid (blue,
such as Loctite 243). We recommend that the user also
employ these devices, both while setting up the partially
assembled machine in this manual, and during the assembly
or maintenance phases: If this is not done, the manufacturer
of the partially assembled machine declines all responsibility
for any accidents, breakage, damage and the consequences
of said events on people, animals and property, due to the
failure of fixing elements.

Notes on lubrication
Safety warnings for handling and transport
Keep the prismatic rail lubricated using oil type VACTRA 2 every 1 year or
2000 km of operations. Keep recirculating ball sliders and rails lubricated
every 1 year or 2000 km of operations using greases between ISO VG 68
and ISO VG 100. In case of heavy loads it is necessary to use greases
type ISO VG 220.
• The manufacturer has paid the utmost attention to packaging to
minimize risks related to shipping, handling and transport.
• Transport can be facilitated by shipping certain components dismantled
and appropriately protected and packaged.
• Handling (loading and unloading) must be carried out in compliance
with information directly provided on the machine, on the packing and
in the user manuals.
• Personnel authorized to lift and handle the machine and its components
shall possess acquired and acknowledged skills and experience in the
specific sector, besides having full control of the lifting devices used.
• During transport and/or storage, temperature shall remain within the
allowed limits to avoid irreversible damage to electric and electronic
components.
• Handling and transport must be carried out with vehicles presenting
adequate loading capacity, and the machines shall be anchored to the
established points indicated on the axes.
• DO NOT attempt to bypass handling methods and the established lifting
points in any way.
• During handling and if required by the conditions, make use of one or
more assistants to receive adequate warnings.
• If the machine has to be moved with vehicles, ensure that they are
adequate for the purpose, and perform loading and unloading without
risks for the operator and for people directly involved in the process.
Never lubricate bearings type 2RS wherever they are present: the pres-
sure exerted during the operation would get the side seals out of seat.
• Before transferring the device onto the vehicle, ensure that both the
machine and its components are adequately secured, and that their
profile does not exceed the maximum bulk allowed. Place the necessary
warning signs, if necessary.
• DO NOT perform handling with an inadequate visual field and when
there are obstacles along the route to the final location.
• DO NOT allow people to either transit or linger within the range of action
when lifting and handling loads.
• Download the axes just near the established location and store them in
an environment protected against atmospheric agents.
• Failure to comply with the information provided might entail risks for the
safety and health of people, and can cause economic loss.
• The Installation Manager must have the project to organize and monitor
all operative phases.
• The Installation Manager shall ensure that the lifting devices and
equipment defined during the contract phase are available.
• The Manager of the established location and the Installation Manager
shall implement a “safety plan” in compliance with the legislation in
force for the workplace.
• The “safety plan” shall take into account all surrounding work-related
activities and the perimeter spaces indicated in the project for the es
tablished location.
• Mark and delimit the established location to prevent unauthorized

must be ensured, in compliance with relevant regulatory and legislative
requirements.
• “State of the art” connection, alignment and leveling are essential to
avoid additional interventions and to ensure correct machine function.
• Upon completion of the connections, run a general check to ascertain
that all interventions have been correctly carried out and compliance
with requirements.
• Failure to comply with the information provided might entail risks for the
safety and health of people, and can cause economic loss.
Packaging
The illustrations present the most common types of packaging used.
• Packaging is done keeping in mind the bulk reduction and the type of
transport chosen.
• Transport can be facilitated by shipping certain components dismantled
and appropriately protected and packaged.
• Some parts, particularly electric, are protected with anti-humidity nylon.
• Packaging for maritime transport is the “overseas” type to guarantee
preservation of the packaged elements.
• The packaging states all the necessary information for loading and
unloading.
• Every shipment is accompanied by a document (“Packing list”) with the
list and description of the axes.
• For shipments via road transport or in “open top” containers, axes that
are not covered by packaging are appropriately protected with a “barrier
bag”.
• Bulk components are appropriately placed along with the axes (with or
without packaging) to avoid sudden and unexpected movements.
• Bulk components that cannot be put together in packages shall be
deposited and appropriately secured to a pallet.
• The packaging material must be appropriately disposed of in compliance
with the legislation in force.

ATTENTION!
If the “Rod Locking” safety system has been
provided with the axis, the correct function-
ing of the fall-stop safety system must be
ensured by a device that releases the pres-
surised air from the pneumatic system each
time an emergency situation arises, due to
either electrical, electronic, mechanical or
pneumatic origin or human factors: the safety
system can only brake the load’s fall if this
condition is met.
Rollon S.p.A. shall not be held responsible if these conditions
are not met.

The scraper with felt (PAR axes) requires no special main-
tenance, it is sufficient its replacement every 12, 24 or 36
months according to the specific case. However, depending
on the dynamics incurred by the system, it may be necessary
to maintain the surface of the prismatic steel guides slightly
moistened, injecting into the scraper with felt cm3of grease
such as “Purpose”, consistency 2, every 500 hours or 10,000
km of operation.
The guides for the recirculating ball slides (PAS axes) must not
be lubricated. Provide greasing the slides for every 500 hours
or 10,000 km of operation, using grease
ranging between ISO VG 68 and ISO VG-100. In the case of
high loads must be used grease type ISO VG 220.
Automatic rack lubrication
Rack lubrication is provided by an automatic greasing system
(optional), which can be operated by an on/off switch located
in the rear part of the lubrication unit: this unit comprises a
replaceable cartridge, a pinion made form Vulkollan and ad-
justable lubrication frequency, depending on the particular
dynamic requirements.
Manual greasing and lubrication
For both PAR and PAS axes, never lubricate bearings type
2RS wherever they are present: the pressure exerted during
the operation would get the side seals out of seat. For axes
equipped with “Rod Locking” safety system unit, never lubri-
cate the sliding calibrated bar.
ATTENTION!
For instructions on routine and special maintenance and for the safety informations about the automatic
greasing system of the rack, refer to the specific manual assembly of the accessory in question.
ATTENTION!
The lubricator cartridge unit must be replaced before having completely run out,
otherwise abnormal consumption of the pinion or the rack may occur.

To replace one or more rack segments it is necessary to
remove the axis from its vertical position and put it in horizon-
tal position. After this, secure it firmly and proceed as follows:
a. Remove the motor and the reduction gear but leave the
shaft and pinion fitted for the subsequent adjustment (refer
to section “Removal and replacement of the drive shaft”).
b. Move the carriage into a position that does not interfere
with the segment of rack to be replaced.
c. Remove plugs (A) using the correct removal tool.
d. Undo socket head cap screws (B).
e. Remove the rack segment concerned (C)
f. Check the positioning of the rack beads (D) and the M8

flush with the upper level of the rack. If one or more plugs
get damaged during the removal, they must be replaced
with equivalent plugs.
i. By moving the carriage slowly, manually check that the
pinion/rack clearance and the pitch on the joint of the
replaced segment are the same as the area in which
nothing has been worked on (for a starting reference do
more tests along the said section). If the clearance is
greater the rack needs to be brought closer to the pinion,
where the clearance is lower the rack needs to be moved
further away from the pinion. Once the clearance has
been properly adjusted, proceed with the final tightening
of the screws, at the end of which a new clearance check
is recommended.
If the clearance between the teeth is more than antic-
ipated, it will result in noisy and inaccurate movement
(especially for changes of direction). If the clearance
is lower, there will be abnormal consumption of the
teeth which would result in damage to the system. If
the pitch between the rack segments is incorrect, it
could cause serious damage to the teething.
j. Proceed with greasing the replaced segment. If the rack
segments to be replaced total more than one, you must
replace one segment at a time, to avoid losing the initial
references.
k. Perform the operation in reverse for refitting.
