3. Design
A rotator consists of a base plate (1) and a rotary joint (2), which is hydraulically driven via a gear
box (3) with bevel gear (4) and an oil motor (5). A flange (6) is bolted with the rotary joint (2) and a
fork carriage (7). The fork carriage (7) has safety retaining stops (8) and limit stops (9) that lock the
fork arms when rotating. This combination is attached to the fork carriage of the lift tr8ck with upper
(10) and lower brackets (11). The optional side shift (12) is equipped with support rollers (13) and is
bolted or welded onto the ground plate (1).
3.1 Efficient equipment settings on electric vehicles
Please use our reference values for setting the lift trucks and attachments. These are
found at www.kaup.de in the Services -> Product Support section.
3.2 Proper use of the equipment
Rotators are intended for rotating loads such as crates, containers etc. that have been picked up
with fork arms. The rotation can be continuous or limited to 180°, to the left or right as required. The
optional side shift is designed for moving loads that are free of the ground (at least 10 cm high).

Operating Manual
8
Original Operating Manual
Proper use of the machine and/or equipment includes the following:
Observance of the operating manual at all times.
Observance of the technical data on the identification plate on the attachment.
Adherence to the specified inspection and maintenance instructions.
3.3 Improper use
Exceeding the allowable load capacity and load centre.
Exceeding the maximum permitted torque.
Transporting persons with the load or load handling devices
Mounting auxiliary equipment on the attachment such that the original mode of usage
is changed, (e.g. fork extensions) must be authorised by the manufacturer.
3.4 Hydraulic oil flow required
When the hydraulic oil flow is insufficient, the speed of rotation of the rotary units at
the attachments will be reduced.
When the hydraulic oil flow is too high, the hydraulic oil temperature will raise which
will reduce efficiency and increase wear.
Please refer to the following Specifications:
ISO Class,
Model family,
Oil flow.

4.1.2 Fork carriage

Replace the plug screw (6) in the gear box with the vent screw supplied.
Ensure that no oil leaks out of the gear transmission.

Hoist the attachment at the positions indicated (1).

Demount the lower hooks (2).

Mount the attachment on the fork carriage of the lift truck (3).

Check that the attachment is correctly seated in the centre lock (4).

Mount the lower hooks (2), tightening the screws (5) with a torque of 190 Nm.

Connect the hose lines (7) to the hydraulic connectors on the lift truck.

Demount the safety retaining stops (8) and limit stops (9) and slide the fork arms


Ensure that all safety retaining stops (8) and limit stops (9) are remounted.

Before initial operation, check the functions and the identification of the attachment
with the movement directions of the operating elements (operating lever, joystick,
etc.).

Mount the residual carrying capacity notice and identification of the operating
elements (if not already present) of the combination of lift truck/attached equipment
on the lift truck.

Operating Manual

4.2 Checking out
KAUP-attachments are delivered pre-lubricated. If the attachment has been in storage
for a longer period, we recommend that it be lubricated again before being placed in
service. See 6. Maintenance and onwards.
Failure of the safety devices (e.g. the pressure relief valve and the non-return
valve) and incorrect connection of the controls to the actuators can cause
malfunctioning of the attachment and damage to it.
After mounting and before initial operation, check the functions and the
identification of the attached equipment with the movement directions of the
operating elements (operating lever, joystick, etc.).
4.2.1 Bleeding the hydraulic system

Start the lift truck.

Move the sideshifter repeatedly in both directions to maximum extent.

Rotate the rotator left and right several times.

Inspect the hydraulic connections for leakage.
4.2.2 Adjustment after putting into service
The hydraulic system is under pressure. During work on hydraulic components
oil spurting out can cause injuries. Unload the system in accordance with the
operating instructions of the lift truck manufacturer. In the case of injuries
caused by high pressure oil, inform the works physician and seek out a
specialist immediately.
5. Operation
5.1 General
At least once per working shift, the machine and equipment must be inspected for
visible damage and defects.
Repeat faults to your superior and have them rectified without delay.
Be aware of persons present in the area where you are working or driving and ensure
that they are not endangered.
Do not transport any load exceeding that specified on the residual load plate for the
particular combination of lift truck and attachment.

Operating Manual
12
Original Operating Manual
5.2 Load handling
Set the forks as wide apart as possible for the load to be carried.
Position the mast vertically and take up the load parallel to the floor.
Drive the attachment up to the load to maximum extent.
Raise the load about 300 mm and tilt the mast backwards.
Centre the load to the middle of the lift truck during take-up and transport.
5.3 Driving
Make sure the load to be lifted and the pressure plates are in perfect condition.
Do not drive with the mast tilted forward.
Take care when driving that neither the attachment nor the load comes into contact
with the ground.
5.4 Rotate
Rotation can cause damage to the load and the attachment.
Ensure sufficient distance of the load to the floor, the ceiling, to shelves, etc.
If higher torque than specified is generated by the load, the rotation device
rotates uncontrolled or not at all.
This can lead to damage to the load and the attachment.
Note the torque given on the type plate of the attachment.
The torque given on the type plate refers to the pressure difference of 125 bar at the
hydraulic motor.
Only rotate loads parallel to the floor (set lifting frame vertically).
Do not rotate loads if there are people in the working area.
Rotate raised loads slowly.
Fast rotating can influence the stability of the lift truck.

6. Maintenance and servicing
6.1 General
Regular maintenance is essential to ensure reliable operation and long service life of the KAUP
attachment.
Ensure that maintenance and servicing are performed by qualified and authorised
personnel only.
Lubrication and cleaning work on the attachment may also be performed by the lift truck
operator.
Perform maintenance and servicing work only when the attachment is parked securely
on a stable, level foundation. For installing and removing, it is recommended to use a
pallet to take the attachment. The attachment can thus be securely placed and
transported.
Pay attention to a sufficient load-carrying capacity of the lifting means.
Replace missing or defective warning signs on the attachment.
Do not use third party spare parts. Through poor quality or incorrect matching
they can result in a risk of accident. The EC Declaration of Conformity by the
manufacturer becomes invalid and you assume full responsibility in the case of
accident.
Use only original spare parts from the manufacturer.
The hydraulic system is under pressure. During work on hydraulic components
oil spurting out can cause injuries. Unload the system in accordance with the
operating instructions of the lift truck manufacturer. In the case of injuries caused
by high pressure oil, inform the works physician and seek out a specialist
immediately.
Screw connections can loosen due to vibration of the attachment. During routine
maintenance check that screw connections are correctly torqued and replace
screws which are visibly damaged.
Note the following tightening torques which are valid for screws with connecting surfaces according
to ISO 4762, ISO 4014, ISO 4032 etc.:

During any disassembly operations, be sure that parts to be disassembled can easily be
removed. For removing parts, use the clearance between bolts and the parts to be
removed.
Our service videos available at www.kaup.de in the Online Services section may be
used for assistance as necessary.
Failure of the safety devices (e.g. the pressure relief valve and the non-return
valve) and incorrect connection of the controls to the actuators can cause
malfunctioning of the attachment and damage to it.
After mounting and before initial operation, check the functions and the
identification of the attached equipment with the movement directions of the
operating elements (operating lever, joystick, etc.).
6.2 Significant modification
Significant modifications are, for example, those which affect the stability, performance, speed and
strength of components.
The EC Declaration of Conformity is invalidated by a significant modification of the attachment.
Modifications to the attachment may only be made with prior approval by the manufacturer.
