Tensjoni eċċessiva taċċellera l-ilbies tar-romblu, filwaqt li tensjoni insuffiċjenti tikkawża derailment. Proċedura standard:
Ipparkja fuq l-art tal-livell, kejjel nofs - span sag (ottimali: 20-30mm);
Aġġusta l-volum tal-grass fiċ-ċilindru tat-tensjoni (5ml grass ≈ 3mm SAG bidla);
Post-adjustment, test under no-load: replace track links if pin-bushing clearance >1.5mm.
