General guidance only — always follow the operation and maintenance manual for your specific machine.
Short answers to precise questions on the mast, stabilisers, chains, forks and frame of the Fantuzzi SF side-loader lift trucks, one fact per card, each with its source stated in the text. For the overall picture, see the Fantuzzi SF technical legacy guide.
Fantuzzi SF U: what makes up the mast assembly?
A fixed mast, a telescopic mast, lifting cylinders, hoist cylinders with their chains, the equipment plate and the equipment itself, according to the hoist section of the 2003 maintenance manual, the HIT SRL technical desk notes.

Fantuzzi SF U: what does the joystick control?
According to the operator's manual, it raises and lowers the forks, extends the mast to pick up or set down a load and retracts it to rest the load on the frame, as logged by the HIT SRL technical desk. The manual states that retraction improves stability and narrows the machine for travel, as recorded at HIT SRL. According to the same manual, a button on the joystick tilts the forks, as recorded by the HIT SRL technical desk.

Fantuzzi SF: how does the machine tilt the forks?
Through the stabiliser cylinders, according to the 1998 SideLIFTS manual, as recorded at HIT SRL. The manual explains that lifting the stabiliser cylinders lowers the forks and lowering them lifts the forks, which helps fork insertion under the load and steadies the machine in travel and lifting, as recorded by the HIT SRL technical desk.

Fantuzzi SF 30-40 E: which control levers does the O.M.F. handbook show?
Separate levers for lift and lower, for mast traverse and for deck or fork tilt, plus a mechanical parking brake lever, according to the O.M.F. handbook, as HIT SRL's technical desk reads it. The handbook shows them next to the brake pedal and the accelerator pedal, as recorded by the HIT SRL technical desk.

Fantuzzi SF U: how many mast thrust shoes are there and when are they replaced?
There are eight, two at the top of the fixed mast, two at the foot of the telescopic mast and four on the equipment plate, and they are replaced when the gap to the opposing section exceeds 1.5 mm (1/16 in), as set out in the HIT SRL technical cards. They protect the slide rollers, according to the 2003 maintenance manual, the HIT SRL technical desk notes. According to the same manual, they limit side swing of the telescopic mast and plate, as recorded by the HIT SRL technical desk.

Fantuzzi SF U: which lifting chains are used and how are they adjusted?
Only BL-type leaf chains are used on the lifting unit, according to the 2003 maintenance manual, as logged by the HIT SRL technical desk. They are anchored to the top of the mast and to the equipment plate, and the same manual allows adjustment only at the plate end, with both chains set to the same tension, as recorded by the HIT SRL technical desk.

Fantuzzi SF: when is a lifting chain replaced?
When it is stretched by 3% or more over ten pitches, measured along its whole length on both sides, according to the O.M.F., SideLIFTS 1998 and SF 60 / SF 80 handbooks, the HIT SRL technical desk notes. The same handbooks have the anchor pins and the sprockets replaced together with the chain, as recorded by the HIT SRL technical desk.

Fantuzzi SF U: how are the lifting chains cleaned and lubricated?
With a brush and non-flammable solvent, a degreasing liquid or a high-pressure cleaner at 90° or more, according to the 2003 maintenance manual, as recorded at HIT SRL. The same manual then has it lubricated by brush with the specified lubricant until it saturates the chain, as logged by the HIT SRL technical desk. The same manual asks for the lubricant to penetrate between the links and the pins, with the load off the chain, as recorded by the HIT SRL technical desk.

Fantuzzi SF U: when are the forks withdrawn from service?
When a measured thickness falls below 90% of the original, the inclination exceeds 3°, the height difference between the two forks exceeds 3% of the blade length or the straightness error exceeds 0.5% of the length, according to the 2003 maintenance manual, the HIT SRL technical desk notes. The same manual has cracks checked with penetrant liquid, magnetic particles or ultrasound, as recorded by the HIT SRL technical desk.
