Page 12: Basic Safety Information
SAFETY Basic safety information The basic safety information comprises all safety measures grouped by theme and is applicable at all times. In addition, the information is presented as warning notices at the correspoding positions in these operating instructions. Basic dangers Mortal danger exists when persons are lifted or carried with the front loader.
Page 13 SAFETY Hydraulic dangers There is a risk of injury due to escaping hydraulic fluids under high pressure. Observe the safety stickers on the machine.   Check the hydraulic couplings and lines for leaks before uncoupling.  On tractors without a closed driver’s cab, mount tubes with splash guards. There is a risk of crushing when machine parts move uncontrollably due to entrapped air in the hydraulic system.
Page 14 SAFETY Dangers during packaging and transport There is a risk of injury due to crushing, impacts or pinching if the front loader tips over or falls from the lifting gear. During all preparatory work, always ensure a secure stand of the machine. ...
Page 15 SAFETY Dangers when picking up and putting down implements There is a risk of serious injury and lethal danger due to implements falling down or uncontrolled lowering of the front loader when unsuitable implements are used or if the used implements are overloaded. ...
Page 16 SAFETY 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.
Page 17 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.

Page 38: Functions
FUNCTIONS Functions Implement locking mechanism 4.1.1 Mechanical implement locking mechanism Euro, SMS and Combi change frames ⚠ WARNING Risk of injury due to implements falling down! The implement may fall down if the implement locking mechanism is open or not locked correctly. This can cause serious injury to persons standing in the surrounding area.
Page 39 FUNCTIONS 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.
Page 40: Hydraulic Implement Locking Mechanism - Hydro-Lock
 The hydraulic implement locking mechanism must only be installed by a specialist workshop.  Only use switches that are approved by STOLL.  Set the implement on the ground or on a safe support before using the implement locking function.
Page 41: Basic Functions
FUNCTIONS 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. ...
Page 42 FUNCTIONS Lowering The 2 lifting cylinders are retracted and thus lower 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.
Page 43 FUNCTIONS Dumping The 2 implement cylinders are extended and thus swivel the implement downwards. The load is dumped out. B01M Fig. 26 Dumping function Legend Implement cylinders on the left and right Implement B58FZS 0000000078 EN 002...
Page 44: Float Position
 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.
Page 45: Lifting Arm Float Position
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...
Page 46: Indicator For Implement Position
FUNCTIONS 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.
Page 47: Rapid Traverse Emptying (Fs) And Quick Emptying (Fz-L)
FUNCTIONS 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.
Page 48: Return-To-Level (Fz-L)
FUNCTIONS 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.
Page 49: Anti-Lowering Guard
FUNCTIONS Setting the return-to-level position: (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) Loosen the clamping screw. (5) Push the tube in the support until there is a space of about 10 mm between the top end of the rod and the top edge of the sensor.
Page 50: Additional Functions
FUNCTIONS Additional functions 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).
