Safety advice for the adjustments
To protect the people involved, the adjustment operations must be carried out with
all safety devices activated and unauthorised people must not be allowed to access
the area of operation which must be appropriately marked.
Before starting the machine, check that there are no tools, cloths or other material
near the moving parts or in risk areas.
Adjusting track tension
Danger - Warning
The tensioning device (valve and lubricator) is pressurised.
To avoid dangerous situations loosen the valve by maximum one turn and never un-
screw the lubricator.
Proceed as outlined below.
1) Stop the machine on solid and even ground.
2) Switch off the engine and remove the ignition key and keep it in a safe place.
3) Lift the machine off the ground the bare minimum needed and block it with external
means to prevent it from accidentally coming down.
4) Unscrew the screws (A) and remove the cover (B).
5) Check track tension.
Tension is correct when the tension at the centre track roller is between 10 and 15 mm.
If the tension is greater than the maximum allowed loosen (maximum 1 turn) the valve
(C) to reduce pressure and set the correct track tension.
Tighten the valve (C).
If the tension is lower than the minimum allowed pump grease from the lubricator (D)
to restore the correct track tension.
6) Fit the cover (B) and tighten the screws (A).
