structure) / ROPS (roll-over protection structure) within the framework of work
safety regulations.

 If there is no cab or safety equipment, never lift loads over the driver's seat.

 Only use suitable implements, which prevent e.g. rolling back and falling on the

driver's seat.

B58FZS 0000000078 EN 002 14

Dangers when operating the front loader

There is a risk of serious injury or lethal danger due to tipping of the tractor when working
on slopes, when going around bends, when the load on the rear axle is too low, and when
driving into the bulk to be lifted at a skewed angle.
The risk increases when the front loaders are raised up high because of the higher centre
of gravity.

 Drive carefully when working on slopes. Never travel with a raised load across a

≥ 20%

10 km/h

slope.

 Ensure that the ground is level enough.

 When driving in curves, reduce the speed and lower the load.

 Never start driving abruptly with the front loader raised high and fully loaded.

 Observe and comply with the maximum load of the tractor.

 Always use sufficient counterweights at the rear of the tractor.

 In case of instability or tipping, lower the front loader and remain in the driver's cab.

 Use the safety belts.

SAFETY

 Connect the brake pedals.

 Switch off the front axle suspension.

 On tractors with adjustable track width: set the maximum possible track width.

When driving on roads, there is a risk of serious injury and lethal danger for the operator
as well as for other road users if the tractor and the front loader a re no t correctly p repared
and operated for road traffic.

 Only drive on roads without a load.

 Before driving on roads, switch off the hydraulic system and lock it.

 Raise the front loader.

15 B58FZS 0000000078 EN 002

SAFETY

Dangers due to falling loads

There is mortal danger due to raised loads falling down on the driver's seat. There is a
particularly high risk when lifting pallets or bales above the driver's cab and when working
on slopes. Even the standard protection systems (roll-over protection structure ROPS,
falling objects protective structures FOPS) do not provide fully adequate protection.

 When working on slopes, reduce the implement filling and lower the load.

 Check the inclination of the implement. Do not scoop too far with the implement.

 Use implements that are designed such that they prevent loads from falling onto the

driver's seat.

 Only use the appropriate implements when loading piece goods (e.g. bale grabber

for bales or pallet fork for pallets).

 Lift pallets or bales one at a time. Never stack several loads on top of each other,

since the top load could fall down on the driver's seat.

 Compensate for the increased angle on front loaders without parallel motion when

lifting by “dumping” with the implement.

 Do not operate the front loader without parallel motion while driving in reverse.

 On tractors without a cab or 4-post roll-over protection structure, do not lift large

load items, in particular bales, any higher than the pivot point of the lifting arm.

 Watch the load as you are lifting. Do not lift the load when reversing.

Dangers during maintenance

Maintenance work carried out incorrectly (care and cleaning, service, repairs) impair the
safety of the front loader.

 Check the front loader regularly for defects.

 Check mounting parts (brackets) regularly for damage (cracks).

 Care and cleaning work must be carried out correctly.

 Only have repair work performed by authorised qualified personnel.

The mechanical implement locking mechanism
on Euro, SMS and Combi change frames is
actuated manually.

The implement is hinged with its hooks on the top
cross bar on the change frame.

Below, the implement rests on the bottom cross
bar. Both eyelets of the implement project into the
mountings of the change frame.

The locking mechanism is held open by the stop.
When lifting the handle, the locking mechanism is
closed by the spring, as the front loader pin is
pushed through the eyelets of the implement.

When scooping, the handle is lifted by a guide
piece on the lifting arm, and the locking
mechanism closes automatically.

Doe not raise the front load higher than

1.5 m until proper locking of the implement
locking mechanism has been checked!

4.2 Basic functions

⚠ DANGER

Lethal danger due to loads falling down from front loaders without parallel motion!

On front loaders without parallel motion, the implement tilts to the rear when lifting. As a result, the load
can fall on the driver and cause lethal injuries.

 Watch the load as you are lifting. Do not lift the load when reversing.

 Compensate for the increased angle on front loaders without parallel motion when lifting by

“dumping” with the implement.

⚠ WARNING

Risk of injury and material damage caused by falling loads or lowering front loader!

With dumping implements that are long or protrude far to the front, the centre of gravity can shift and
cause the pressure relief valve of the front loader to open by itself. As a result, the front loader dumps
or lowers uncontrollably and can lead to serious injuries and damage.

 Observe the maximum load of the front loader (see 11 Technical specifications).

 Always use sufficient counterweights at the rear of the tractor (see 5.3.2 Ballasting).

 During loading work, instruct persons to exit the working area (see 2.8 Danger zones).

The front loader has 4 basic functions that are required to move the lifting arms and the implement.

Lifting

The 2 lifting cylinders are extended and thus
raise the lifting arm and the implement.

Without parallel motion, the angle between the
lifting arm and the implement remains constant
so that the implement changes its orientation.

With parallel motion, the angle between the lifting
arm and the implement changes so that the
implement maintains its original orientation.

To move the implement, see 4.5 Parallel

motion (FZ, FZ-L).

4.3 Float position

⚠ WARNING

Possible risk of injury due to unexpected movement!

If the front loader is not completely lowered, a vacuum may form in the hydraulic cylinders during the
float position. This causes uncontrolled lowering of the front loader at a later time. This can cause
persons to be injured or crushed.

 Only use the float position when the front loader is completely lowered.

 Do not use the float position with implements that require the presence of other persons!

 Only use the float position if nobody is in the danger zone.

 Do not scoop while in float position.

⚠ WARNING

Possible risk of injury due to unexpected movement!

On FZ-RTL front loaders, the front loader may "sag" during quick emptying if it had previously scooped
when the float position was switched on. This can cause persons to be injured or crushed.

 Do not use the float position with implements that require the presence of other persons!

 Only use the float position if nobody is in the danger zone.

 Do not scoop while in float position.

FUNCTIONS

⚠ WARNING

Possible risk of injury due to the implement tipping over!

On FS front loaders, the float position for the implement may not be activated for the scooping and
dumping functions. This could cause the implement to tip over unintentionally to the rear. This may

result in serious accidents.

 The activation of the float position must be ruled out through the assembly on FS front loaders. If

this is not the case, work with the front loader must be stopped immediately and the specialist
workshop must be contacted, to have the float position deactivated for the scooping and dumping
functions. The front loader may only be used again when the float position has been deactivated for
the scooping and dumping functions.

The float position is used to improve ground adaptation, since the implement can then follow the ground
contours and "floats" on it.

4.3.1 Lifting arm float position

For the float position of the lifting arms, the
hydraulic cylinders are depressurized, i.e., they
are open towards the tank. The front loader lies
on the ground through the pressure of its own
weight.

Activating the lifting arm float position:

(1) Fully lower the front loader.

(2) Move the operating lever all the way to the

front until it engages (see 6.1 Operating
elements).

 The float position is activated.

3Ground

4.3.2 Implement float position

For the implement float position, the front loader must be equipped with Hydac valves as well as parallel
motion and must have a STOLL Pro Control operating element.
The float position for the implement must be explicitly activated in STOLL Pro Control during the
installation.

Activating the implement float position:

(1) Lower the front loader close to the ground.

(2) Move the operating lever to the right and press button T2 (green) (see 6.1.4 STOLL Pro Control).

 The float position is activated.

B58FZS 0000000078 EN 002 44

4.4 Indicator for implement position

The indicator for the implement position is
located on the left implement cylinder. It allows
the horizontal position of the implement to be
read from the driver's seat.

The rod is attached on the lower bearing pin and
runs through the tube, which is attached to the
upper bearing pin with the support. When
dumping or scooping, the rod moves in the tube.
When the implement is in horizontal position, the
rod and the tube are flush.

Setting of the indicator:

(1) Position the implement horizontally.

(2) Lower the front loader to the ground.

(3) Switch off the tractor.

 Apply the parking brake.

 Stop the engine.

4.5 Parallel motion (FZ, FZ-L)

With the parallel motion, the guide linkage
ensures constant orientation/inclination of the
implement.

The function is particularly suitable for loading
pallets and stacking bales.

The function can only be executed when
the implement is horizontal or in scooping
position.

4.6 Rapid traverse emptying (FS) and quick emptying (FZ-L)

⚠ CAUTION

Possible risk of accidents due to improper use of the rapid emptying!

If the rapid emptying is actuated outside of a dumping process, it can cause a strong pressure drop in
the hydraulic system. The resulting imprecise and uncontrolled working behaviour of the front loader
can cause accidents.

 Only use the rapid emptying during dumping processes.

⚠ CAUTION

Risk of accident due to improper use of the rapid and quick emptying!

Use of the rapid or quick emptying on implements with hydraulic functions can cause damage to the
hydraulic lines. This increases the risk of accidents.

 Only use the rapid or quick emptying with implements that do not have hydraulic functions.

Rapid emptying (FS rapid emptying)

An additional valve on the implement cylinder
ensures faster dumping of the implement during
the rapid emptying.

In this case, the hydraulic fluid is diverted from
the scooping side of the implement cylinder to the
dumping side, so that the pump is relieved.

 See 6.1 Operating elements for how to

operate the rapid emptying.

Quick emptying (FZ-L)

With quick emptying, an additional valve on the
implement cylinder causes the load to be
dumped immediately.

The valve establishes a connection between the
scooping side and the dumping side of the
implement. The dumping process starts when
pressing the button and is accelerated by the
implement's own weight and that of the load.

When the button is actuated, the
implement dumps the load immediately
without hydraulic actuation.

 See 6.1 Operating elements for how to

operate the quick emptying.

Fig. 30 Rapid or quick emptying

B58FZS 0000000078 EN 002 46

4.7 Return-To-Level (FZ-L)

⚠ WARNING

Possible risk of injury due to uncontrolled lowering!

Actuation of the RTL button while dumping causes the front loader to be lowered. Moreover, when
dumping with insufficient fluid supply, a vacuum can form in the implement cylinder, which also causes
lowering of the front loader. This can cause injury to persons standing in the surrounding area.

 Only press the RTL button when lowering the front loader.

 Throttle the oil flow as little as possible.

 If necessary, increase the idling speed.

The return-to-level sensor is located on the
indicator on the left implement cylinder. It enables
automatic lowering of the front loader to its pre­set position by pressing a button. This mainly
facilitates loading work that involve repetitive
movement.

To do so, an additional valve on the implement
cylinder diverts the hydraulic fluid flowing out
while lowering. The sensor monitors the position
of the implement and emits the signal for closing
the valve as soon as the implement has reached
its pre-set position.

 The return-to-level position is set.

4.8 Anti-lowering guard

⚠ WARNING

Risk of injury and accident due to implement tipping off!

The anti-lowering guard only prevents the front loader from lowering, however, it does not prevent
accidental dumping of the implement. Persons whose presence is required near the load can be injured
by the load falling down.

 Do not move the front loader as long as people are standing in the danger zone.

 Only start the lifting operation after everybody has left the danger zone.

The anti-lowering guard in compliance with EN 12525/A1 prevents sudden lowering of the front loader.
It is used when working with a raised front loader if the presence of persons is required in the machine's
working area.

The anti-lowering guard is not suitable for use with work cages that are used to transport people.

The operating state of the anti-lowering guard is shown by the lamp on the switch box. If the lamp is on,
the anti-lowering guard is activated. If the lamp is off, the anti-lowering guard is deactivated. In this case,
there may not be any one standing in the working area of the front loader (see 2.8 Danger zones). When

4.9.1 Additional control circuits

⚠ WARNING

Risk of injury due to unexpected movement of the front loader or implement!

If there is an electrical malfunction, operating elements can be temporarily or permanently out of
function. As a result, it is possible that an unintended function is triggered instead of the selected
implement functions (see 3rd control circuit and 4th control circuit). The triggering of unwanted
functions can lead to unexpected movement of the front loader or implement and cause serious injuries.

 Before use, check all of the front loader functions without a load.

 In case of malfunction, stop working with the front loader immediately and contact the specialist

workshop.

For hydraulic functions of the implement, additional control circuits must be installed. The
corresponding hydraulic couplings are located on the change frame and are available as plug-in, screw­in or multiple couplings.

3rd control circuit

With a switch valve for the 3rd control circuit,
hydraulic implement functions are enabled, e.g.
the actuation of a top loading grip.

4.9.2 Comfort Drive

⚠ WARNING

Possible risk of crushing!

The front loader is lowered when the Comfort Drive is switched on.

 Before switching on the Comfort Drive, lower the front loader completely to the ground.

NOTICE

Possible material damage due to overloading!

The Comfort Drive can be overloaded when working with heavy loads (e.g. excavation) and with the
pallet fork, resulting in damage.

 Switch off the Comfort Drive before working with heavy loads.

The Comfort Drive function enables smoother and more comfortable driving with a mounted front loader
during transport and when driving on roads. There is a piston accumulator for this purpose in the cross
tube, which absorbs impact loads caused by driving on uneven ground.

To achieve optimal function of the Comfort Drive, lower the front loader again a little bit after
lifting.

⚠ WARNING

Possible risk of crushing!

Comfort Drive is also activated by switching off the ignition or disconnecting the electrical supply. The
front loader can lower slightly in the process and cause personal injury.

 Completely lower the front loader before switching off the ignition or disconnecting the electrical

supply of the front loader.

⚠ WARNING

Risk of injury and accident due to the front loader lowering!

Accidental actuation of the Comfort Drive switch while driving can cause the front loader to lower, and
if the lifting height is too low (less than 1 m) the front loader can touch down on the ground. This can
cause accidents and people can be severely injured.

 Make sure that the front loader is raised high enough while driving (at least 1 m).

The electro-hydraulic Comfort Drive is actuated
with a switch in the driver's cab.

As a standard, the electro-hydraulic valve is open
here, i.e. it is active when there is no voltage at
the valve.

⚠ WARNING

Possible material damage due to overloading!

The front loader can be lowered unevenly and be distorted when the two lowering throttles are not
adjusted in the same way, and can cause personal injury.

 Set both lowering throttles to the same values.

The lowering throttle is used to set the lowering
speed of the front loader.
There is one lowering throttle on each side of the
lifting arm. Each lowering throttle is adjusted with
the rotary knob. There are numbers on the rotary
knob to enable more precise adjustment.

4.9.4 Camera system

NOTICE

Material damage due to loss of suction force!

Due to a natural loss of vacuum, the suction holder can lose suction force and fall off. This can damage
the camera system.

 Detach the suction holder at regular intervals and fix it in place again.

NOTICE

Material damage due to adhesion!

If the suction holder is in contact with the window for too long, it can firmly adhere to the window and
damaged it.

 Detach the suction holder at regular intervals and fix it in place again.

The camera system consists of a monitor, a camera and the corresponding cable sets.

It enables more precise work with the front loader and the mounted implements.

NOTICE

Material damage due to divided brakes on the tractor!

When the front loader is mounted, one-sided braking can lead to serious damage.

 Couple the brake pedal in the tractor before using the front loader.

The divided brake pedal serve to support the
steering of the tractor and can brake the
respective wheels on each side. Therefore, for
example, small turning radii can be achieved
when driving on roads. When the front loader is
mounted, it is recommended to couple the brake
pedals before start-up.

5.3.2 Ballasting

≥ 20%

B079

⚠ WARNING

Serious injury due to the machine falling over!

When working with the front loader without rear counterweights, the tr acto r can tip over and c ause injury
to the driver and persons in the surroundings. Moreover, there is the risk of overloading the front axle
of the tractor.

 For front loader work, always use sufficient counterweight at the rear of the tractor.

The proper ballasting of the tractor is very
important to achieve sufficient stability. This
stability is influenced by the centre of gravity of
the loaded tractor / front loader combination, the
geometrical conditions, the weight, the
arrangement of the implement and the load in the
implement, the track width and wheel base of the
tractor, acceleration and braking processes as
well as the road conditions, to name a few. A
significant measure to increase the stability is the
addition of counterweights or rear weights, which
is strongly recommended for all front loader work.
If operation with a rear weight is not possible, the
stability can be increased with appropriate
ballasting on the rear wheels (wheel weights) or
with liquid in the tyres.

To determine the require weight for ballasting, the
following conditions apply:

When the front loader is fully loaded with the
implement in the most forward position, the rear
axle must carry min. 20 % of the total weight (sum
of the weight of the tractor, the front loader, the
implement, the load and the counterweight)
(see Fig. 39). This ensures stability and braking
efficacy.

When the front loader is raised without an
implement, the front axle must carry min. 20 % of
the total weight (see Fig. 40). This ensures the
steering capacity while driving.

6.1 Operating elements

6.1.1 Basic controls with levers

⚠ WARNING

Possible risk of injury due to uncontrolled movement of the front loader!

If the control unit was not actuated for a longer period of time, there may be e.g. temperature differences
between the hydraulic fluid and the control unit. This can cause the control valves to jam and the front
loader moves uncontrollably. This may result in serious accidents.

 At ambient temperatures lower than 10 °C and when the front loader is not used for longer than

15 minutes, always first actuate the scooping and dumping functions at a standstill to warm up the
control unit.

 Only use the lifting and lowering functions after the warm-up phase.

⚠ WARNING

Possible risk of injury due to the implement tipping over!

On FS front loaders, the float position for the implement may not be activated for the scooping and
dumping functions. This could cause the implement to tip over unintentionally to the rear. This may

result in serious accidents.

 The activation of the float position must be ruled out through the assembly on FS front loaders. If

this is not the case, work with the front loader must be stopped immediately and the specialist
workshop must be contacted, to have the float position deactivated for the scooping and dumping
functions. The front loader may only be used again when the float position has been deactivated for
the scooping and dumping functions.

 Never use programmed sequences for the front loader.

⚠ WARNING

Risk of accident due to wrong assignment of the hose lines!

If the front loader is connected directly to the auxiliary control units of the tractor with hose lines,
swapping of the hose lines can result in incorrect assignment of the functions on the operating lever.
This can result in unexpected movements and accidents.

 Always mark the couplings on the hose lines and connection points.

 Promptly replace damaged or missing labels.

 Connect the hose lines so that the float position takes place in the actuation direction of the lowering

dumping functions. This could cause the implement to tip over unintentionally to the rear. This may

result in serious accidents.

 The activation of the float position must be ruled out through the assembly on FS front loaders.

If this is not the case, work with the front loader must be stopped immediately and the specialist
workshop must be contacted, to have the float position deactivated for the scooping and dumping
functions. The front loader may only be used again when the float position has been deactivated for
the scooping and dumping functions.

This single-lever control unit may only be
used on tractors with a cab.

The STOLL "Pro Control" operating lever is a
single-lever control unit with integrated buttons
as well as an integrated membrane keyboard.

The control of the operating lever is the same as
the basic controls in section 6.1.1 Basic controls
with levers except for the float position.

The assignment of the buttons is shown in the following table:

6.5 Picking up and putting down the implement

⚠ WARNING

Risk of injury and material damage caused by falling loads or lowering front loader!

With dumping implements that are long or protrude far to the front, the centre of gravity can shift and
cause the pressure relief valve of the front loader to open by itself. As a result, the front loader dumps
or lowers uncontrollably and can lead to serious injuries and damage.

 Observe the maximum load of the front loader (see 11 Technical specifications).

 Always use sufficient counterweights at the rear of the tractor (see 5.3.2 Ballasting).

 During loading work, instruct persons to exit the working area (see 2.8 Danger zones).

NOTICE

Material damage due to unsuitable implements!

The mounting of implements that are too long, too wide or too heavy can cause damage to the tractor,
the front loader or the implement.

 Ensure that the dimensions and weights of the front loader and implements fit to each other.

 Only use implements that are designed for the front loader and the mounted change frame.

 Only use implements that are appropriate for the kind of work you are doing.

 Observe the operating instructions of the implement.

between the hydraulic fluid and the control unit. This can cause the control valves to jam and the front
loader moves uncontrollably. This may result in serious accidents.

 At ambient temperatures lower than 10 °C and when the front loader is not used for longer than

15 minutes, always first actuate the scooping and dumping functions at a standstill to warm up the
control unit.

 Only use the lifting and lowering functions after the warm-up phase.

⚠ WARNING

Risk of accident due to raised front loader!

When driving on roads, the tractor with the raised front loader can tip over and cause serious accidents.

 Always use sufficient counterweights at the rear of the tractor.

 Do not drive faster than 25 km/h.

 Pay attention to changes in the dimensions of the machine.

 Pay attention to the clearance height, e.g. under bridges, power lines and trees.

 Take extra care on bends.

 Pay attention to the longer braking path.

 If necessary, let somebody else guide you at blind spots.

When driving on roads, the tractor with a mounted front loader may only be driven by people who have
the necessary driving license and knowledge of the traffic regulations.

Also to be observed:

 Dismount the implement at a distance of more than 3.5 m between the steering wheel and the front

edge of the implement.

 If possible, raise the front loader such that the top edge of the implements does not exceed a height

of 4 m and the bottom edge of the implements begins at least 2 m above the road surface.

 Activate the road operating lock (see 6.7.1 Activating and deactivating the road operation lock).

 If equipped, activate Comfort Drive (see 4.9.2 Comfort Drive).

 Observe the applicable national traffic regulations.

OPERATION

6.8 Parking the tractor with the front loader

⚠ WARNING

Possible risk of injury due to lowering of the front loader!

The front loader is lowered over time by the drop in pressure in the hydraulic system. This can result in
damage and accidents.

 Always lower the front loader when parking or exiting the tractor.

 Observe all of the action steps to correctly park the tractor with the front loader.

Parking the tractor with the front loader:

(1) Lower the front loader to the ground.

(2) Switch off the tractor.

 Apply the parking brake.
 Stop the engine.

(3) Depressurize the hydraulic system.

 Move all of the operating levers to the end position.

(4) Pull out the ignition key to secure the tractor against unauthorised use.

 The tractor with the front loader is safely parked.

To park the tractor with the front loader, also observe the operating instructions for the tractor.

Instructions for parking the tractor without front loader, see 9.1 Temporary decommissioning.

7 Troubleshooting

⚠ WARNING

Mortal danger and material damage due to lack of safety!

Troubleshooting and repair work carried out incorrectly can impair the safety of the front loader.

 Necessary repair work should only be performed by an authorised specialised workshop.

Faults on the front loader are frequently caused by factors that are not a result of a malfunction on the
front loader.

In case of faults, first check:

 Is there enough oil in the hydraulic tank of the tractor?
 Has the correct oil been used?

Only use oil types specified in the tractor operating instructions. The wrong oil can cause foam to
build up and leaks.

 Is the hydraulic oil clean and free of moisture?

You may need to change the oil and filter.
Install an additional filter in the hydraulic system if necessary.

 Are the hoses and connections mounted correctly?

The connections must be locked in place.

 Are the hoses and connectors undamaged, not clamped or twisted?
 Have the cylinders of the front loader been moved several times into their end positions to remove

the air from the lines and the cylinders?

 Have you taken the low outside temperatures into consideration?

Is the oil at operating temperature already?

If these points do not resolve the problem, the following table will help to localize and correct the fault.

TROUBLESHOOTING

Incorrect repairs can lead to safety risks. That is why the repair work must only be carried out by
suitably qualified personnel!
STOLL recommends that the repair work be performed at a specialised workshop.

⚠ WARNING

Serious risk of injury due to uncontrolled lowering of the front loader!

During service and repair work, a raised front loader can be lowered unexpectedly and crush and injure
nearby persons.

 Only perform maintenance work when the front loader is completely lowered.

⚠ WARNING

Risk of injury due to the front loader tipping over!

When the front loader is put down on the parking supports, it does not have sufficient stability to perform
maintenance work. The front loader can tip over and cause serious injury to persons standing nearby.

 Only perform maintenance work when the front loader is mounted.

 If mounting is not possible, secure the front loader against overturning using a crane or with load-

bearing ropes or chains.

⚠ WARNING

Risk of injury due to hydraulic fluids under high pressure!

Even when the tractor is switched off or the front loader has been removed, the hydraulic system can
still be under pressure. If the service work is not carried out correctly, oil can spurt out at high pressure
and cause serious injury to persons standing nearby.

 Before opening the couplings or dismounting hydraulic components, depressurize the hydraulic

system.

 Always used suitable auxiliary materials when searching for leaks.

 Never search for leaks using your fingers.

⚠ CAUTION

Risk of burns by hot machine parts!

Hydraulic components as well as other parts of the front loader and tractor can get very hot during
operation. This can cause burns to the skin when performing maintenance work.

 Allow the machine and components to cool down to under 55 °C before performing maintenance

work.

Repairs help to maintain proper functioning of the front loader and prevents premature wear.
