Introduction
1.2 Warning symbols
Warnings are used in this manual to protect you from injury and to protect the machine from damage.
Always read and comply with these warnings. Warnings are shown in bold font.
Warnings are introduced with the words Danger or Caution .
The two warning levels have the following meaning:
Danger
If the warning is ignored, there is danger of death, severe injury or significant machine damage.
Caution
If the warning is ignored there is danger of injury or machine damage.
Supplemental comments begin with the word
Comment
These comments facilitate understanding or execution of a certain procedure.
1.3 Intended use of the front loader
The front loader has been built exclusively for agricultural and forestry loading tasks.
It should only be used with the implements provided by STOLL.
It should only be attached to those tractors for which STOLL designed it to be attached, and for which it is
offered by STOLL.
The front loader must only be operated from the driver seat of the tractor.
The front loader and its tools must never be hydraulically operated together with other devices at the same
time.
The Frontloader may not be used for lifting operations that require the presence of a person close to the
lifted load. There is a risk that persons are squeezed between load and or ground on failure of the hydraulic
components. For possible works with such tools the Frontloader is to be equipped with security equipment
and to activate this.
Danger
Any use extending beyond intended use is non-intended use. The manufacturer, STOLL, assumes no
liability for damage resulting from non-intended use. This risk is borne solely by the user.
Intended use also includes compliance with the operating and service instructions prescribed by the
manufacturer.
The front loader should only be used and maintained by persons who are familiar with the contents of the
operating manual through appropriate reading and instruction, and who have been particularly instructed
concerning the dangers associated with operation of the front loader.

of each other. The upper loads can fall on you.
Danger
Check the implement tilt when lifting the front
loader.
Raised loads can fall on you if you scoop the
implement too far.
Danger
During lifting with FS Frontloaders the tool angle
increase and the load can fall on you.
You must compensate for the angle increase by
dumping the tool.
Preferably use FZ front loader on tractors without
cab.
Here, the risk of falling loads is lower, as when lifting
the loader, the tool’s angle remains constant and the
scooping is limited.
Danger
When driving on curves reduce the speed and
lower the load.

3.3 Operation of the front loader
A…front loader - lifting
B…Front loader - lowering
C…Implement - scooping
D…Implement - dumping
S…Front loader - float position
Lifting:
Pull the operating lever back to lift the front loader (A).
Lowering:
Move the operating lever forward to lower the front
loader (B).
Caution
Do not lowering the Frontloader in floating position.
Likewise, in lowering do not reduce oil flow too much,
if necessary, increase idle speed.
Otherwise, due to the formation of vacuum in the
lifting cylinder, the raised Frontloader can lower in
dump function.
Scooping:
Move the operating lever to the left to scoop the
implement (C).
Dumping:
Move the operating lever to the right to dump the
implement (D).
Float position:
If you push the operating lever all the way forward, the
operating lever will lock in float position (S).
In float position the front loader lowers to ground level.
When driving with float position the front loader adjusts to
ground level.
Caution
Activate float position only with lowered Frontloader.
Otherwise, due to the formation of vacuum in the
lifting cylinder, the raised Frontloader can lower in
dump function.
Deactivate float position by pulling the operating lever back
into neutral position.
Re-scooping (lifting + scooping):
Move the operating lever back and to the left
simultaneously. The implement will be scooped to the
maximum tilt angle and then raised.
Re-scooping is achieved for FZ, FZ+ and FZ L front loaders
in this manner. During the lifting process the tilt angle of the
implement is simultaneously increased.

Frontloader
3.3.1 Operation via tractor hydraulics
The front loader is operated via two supplemental hydraulic control devices of the tractor.
Four hydraulic lines connect the tractor hydraulics directly with the front loader.
Please identify the couplings in such a way that the float position follows “Lower implement“ in the operating
direction when directly connected with additional controllers by using hose connections.
Shut the front lifting equipment and any coupled implement off before starting work by closing the shut-off
valve or disconnecting the hose couplings.
Almost all tractors with supplemental electro-hydraulic control units have a joystick located to the right of the
driver seat. This joystick enables convenient loader guidance.
The joystick may not engage in deflected position (exempt float),otherwise the locking have to be cancelled!
Danger
The front loader must not be controlled by any sequential programme. Adhere to the tractor
manufacturer’s instruction manual!
Danger
The used hydraulic control devices must never be operable from outside the driver cabin, in
particular not from the external controls of the front linkage.
If this cannot be guaranteed, the additional controls have to be reprogrammed or permanently disabled.
Installation is described in the tractor-specific installation instructions.
3.3.2 Operating the single-lever control unit (EHS)
The tractor is equipped with a mechanical control
block on the add-on part.
The operating lever is installed in the tractor cab.
The operating lever is connected to the control block
via two Bowden cables.
The EHS enables easy, precise, and safe loader
guidance.
Installation of the EHS is described in the installation
instructions
A 874 (order no.:2360630).
3.3.3 Operation via joystick (EHS Eco-Pro, EHS Pro)
The tractor is equipped with an electro-hydraulic
control block on the add-on part.
There is a joystick in the tractor cab.
The joystick is connected to the control block via an
electrical cable.
The joystick enables easy movement and fatigue-free

Use the buttons integrated in the operating lever to
switch the supplemental hydraulic functions of the
front loader.
Different supplemental functions are offered to you
depending on the front loader type.
The 3rd and 4th control circuit is an optional
supplemental function for all front loader types.
For FS quick motion, FZ+ and FZ L front loaders use
the rocker switch in the tractor cab to select the
function you would like to execute with button a.3rd
control circuit or rapid traverse emptying or fast
emptying).
If the FS quick motion, FZ+ or FZ L front loader does
not have a 3rd control circuit, then neither does it have
a rocker switch for changing the function.
Danger
The Hydro-Lock function should not be placed on
a operating lever button.
Switch this function via a rocker switch installed
in the tractor cab.
3.4.1 3rd and 4th control circuit
The 3rd and 4th control circuits are additional doubleaction
oil circuits on the front loader. With this circuit
you control the additional hydraulic function of the
implement.
Implements with additional hydraulic functions, are
silage grippers, bale grippers and bale lifters.
The supplemental function is activated via the
implement activation (scooping, dumping)
On the operating lever press button a or b (c) and
simultaneously move the control lever to the right or
left. This controls the 3rd or 4th supplemental function
of the front loader.
This de-activates implement activation. Release the
button to operate the implement again.
22

Frontloader
3.4.2 Fast emptying (only FZ+ an FZ L)
3.4.3 Rapid traverse emptying (only FS quick motion)
Fast emptying enables fast dumping of the implement.
To execute fast emptying keep button a depressed.
Due to the weight of the load and the implement the
implement quickly dumps. Fast emptying stops when
you release the button.
Fast emptying can also be executed during the lifting
and lowering process of the front loader.
Caution
Never lowering Frontloader in float position and lift by
scooping tool. In subsequent fast emptying the raised
loader falls down.
Comment
If the implement is on the ground, you reach a float
position of the implement via the fast emptying. When
driving, the front edge of the implement adapts to the
ground level.
Rapid traverse emptying enables fast dumping of the
implement.
When dumping press button a, this accelerates the
dumping out process.
Danger
Only press the button when you dump out the
implement. Otherwise there is a danger of air
getting into the hydraulic system.
3.4.4 Active re-scooping (only FZ+)
For front loaders with mechanical parallel guide you
can also re-scoop when lifting the implement.
With lowered front loader the implement can be
scooped to a tilt angle of approximately 45 degrees.
During the lift movement you can re-scoop by an
additional 25° to approx. 70°.
Press button b while you are lifting the front loader.
This re-scoops the implement while lifting.
This function facilitates implement filling when loading
bulk goods.
Comment
If the implement is maximally scooped, you must
release the button otherwise the front loader will not
lift any higher.
This function is not available when lowering.
23

Frontloader
3.4.5 Return To Level (only FZ L)
3.5 Attachment and removal of the front loader
Press the switch b during the loader’s lowering.
So, the tool will scoop until the pre-programmed
position.
The loading work is simplified, because the tools
reach the loading position, without use of the scoop
function.
Low the loader always at the same speed, otherwise,
the tool will not be at the correct position.
The sensor’s setting in order to program the tool’s

3.8 Mechanical parallel guide (FZ, FZ+, FZ L)
When lifting and lowering the front loader the
implement is guided parallel through the guide
linkage. This keeps the incline of the implement
constant when lifting and lowering.
The mechanical parallel guide is helpful for all load
tasks. This function is particularly important when
loading pallets and for stacking bales.
Comment
The parallel guidance is particularly effective with an
implement that is horizontal or scooped. It does not
function with an implement that is tilted out.
Check the horizontal implement position via the level
indicator. (Section 3.7).

6.4 Troubleshooting
Faults on the front loader are frequently caused by factors that are not due to a front loader malfunction.
Many problems can be avoided through regular maintenance.
If there are faults, please check the following first:
• Is there sufficient oil in the tractor's hydraulic oil tank?
• Are you using the right oil? Only use oil as specified by the operating manual of the tractor. The wrong oil
can cause foaming and leaks.
• Is the hydraulic oil clean and free of moisture? Replace oil and filter if necessary.
• Are hoses correctly mounted?. The connections must be locked in place.
• Are hoses and connections damaged, jammed, or twisted?
• Were the cylinders of the front loader moved into their end positions several times to get the air out of
lines and cylinders?
• Have you taken low outside temperature into account? Has the oil reached operating temperature?
If the measures described above are unsuccessful, the following table may help you to localise and correct
the fault.
If you require support, contact your dealer.
