2.1 Use and upkeep of this manual
This “User Manual” (hereinafter referred to as Manual) is supplied together with the A.T.I.B. -
WIDE OPENING FORK POSITIONER TYPE 883 pursuant the CE DIRECTIVE 2006/42/CE
date 17/05/2006 and amendments.
The information contained here are imperative for the correct use of the attachment and must
be known by the personnel who install, use, maintain and repair it.
This manual must be considered integral part of the attachment and must be kept as long as the
attachment is in use on any machine in an accessible place, protected, dry and available for
immediate consultation.
Should this manual be lost, the operator can apply for the supply of further copies from the
manufacturer.
The manufacturer is not liable in cases of:
- Improper use of the attachment;
- Use by untrained personnel;
- Use contrary to current national and international laws;
- Lack of recommended maintenance;
- Non authorised modifications and repairs;
- Use of non original spare parts or parts for other models;
- Failure to adhere, either totally or partially, to these instructions;
- Exceptional circumstances.
The manufacturer reserves the right to modify this Manual without notice and without
the obligation to update the copies previously distributed.
The Nominal Capacity of the forklift / Equipment combination is established by the
original manufacturer of the forklift and may be lower than that indicated on the
identification plate.
Consult the plate of the forklift (Directive 2006/42 / EC).

The A.T.I.B. - WIDE OPENING FORK POSITIONER TYPE 883 were planned and built to enable
the distance adjustment between fork centres through hydraulic actioning, all at the expected
operating pressures unless otherwise indicated in the case of specific applications (see
identification label).
SLI = with INTEGRAL SIDESHIFT
SLS = with SEMI-INTEGRAL SIDESHIFT
FB = with BOLTED FORKS
FS = with WELDED FORKS
This equipment must be applied between the fork holding plate of the lift truck and the forks,
and connected to the distributor by means of a hydraulic circuit.
The relative adjustment movement is carried out by means of two hydraulic cylinders which
act directly on the forks, which, suitably modified, slide on the relative bars.
The coupling components of the fork holding plate are manufactured in compliance with the
ISO 2328 norm.

Verify the nominal capacity of equipment
To check the nominal capacity of equipment, consult the identification label (Tab 1 pag.6).
Check operating pressure and flow rate oil
A.T.I.B. advises to respect the hydraulic flow rates and operating pressures shown in Tab 2, in
order to optimize the operation of the equipment and avoid problems during the work or
commissioning phases. The values are indicative and may vary depending on the equipment.

WARNING
Make sure that the operator of the forklift is aware of the maximum capacity of the
attachments, so as NOT to pose a danger to himself and to the people who work in his
vicinity.

3.1 Installation
3.1.1 Attachment installation - TYPE 883
1. Before installation, verify the condition of the fork carriage,
ensuring that it is not deformed.
2. Also make sure that the profiles of the fork holding plate are not deformed, in order to allow
a good coupling with the equipment.
3. Check the condition of the pipes, replacing those that are in a bad condition.
NOTE: The following figures show only the 883 standards, since the procedure for installing
the equipment on the forklift is the same for welded forks and bolted forks type.
4. Unscrew the lower hooks of equipment (Picture 2).

5. For handling, use belts or chains appropriately sized for the weight of the equipment,
indicated on the identification plate (Picture 1 and Tab 1 pag.6).
6. With an overhead crane or with a hoist of sufficient capacity hook the attachment to the
fork carriage, placing the centring tooth Cinto the central notch (Picture 3).

7. Screw the two bottom hooks Gwith bolts so that the attachment is safely mounted on the
fork carriage P(with a tolerance max. 1,5mm Picture 4), reaching to the following torques
Tab 3.
8. Insert the forks.
9. Lubricate the contact parts.

3.1.2 Attachment installation - TYPE 883 with SLS
1. Before installation, verify the condition of the fork holding plate,
making sure that the lower profile is free of roughness that could
compromise the sliding of the lower slides.
2. Also make sure that the profiles of the fork holding plate are not deformed, in order to allow
a good coupling with the sideshifting equipment.
3. Check the condition of the pipes, replacing those that are in a bad condition.
NOTE: The following figures show only the 883 standards, since the procedure for installing
the equipment on the forklift is the same for welded forks and bolted forks type.
4. Manually take the double hook A(with the relative sliding bushings), after having
unscrewed the screws of the "protective fold" Pand place it on the upper profile of the fork
holder plate, taking care to fit the centring pin Cin the central notch of the same (Picture 5).
5. Unscrew the lower hooks of equipment and lubricate the slide (Picture 6).
