6. Maintenance Operations
The performance of certain maintenance, adjustment or repair operations
will be determined by the owner’s facilities.
Work can be carried out with the machine supported on its own wheels
or, alternatively, with the machine still attached to the tractor.
WARNING
If the GBS 1200 is left on the tractor, under no
circumstances rely on the tractor hydraulics.
Securely block up the machine with jack
stands before attempting any maintenance.
DANGER
Raise the GBS 1200 clear of turf or surface,
disengage the P.T.O., turn off the engine, set the
park brake and remove the key before carrying
out any maintenance or servicing.
6.1 Adjustments and Settings
The P.T.O. from the tractor drives the gearbox, which in turn drives the
blade reel via two sets of drive belts.
1. Remove the side belt covers (0984 & 0985).
2. Adjust the tension by loosening the lock nut on the idler adjuster
(0424) and screwing the adjusting nut on the end. Re-tighten the
lock nut when correct tension is achieved.
3.
Note :
The recommended tension is 1.0 - 1.5 Kgf (2.2 - 3.3 lbf) to give
a deflection of 6mm (1/4 in.) in one of the belts at the mid point
between the two pulley centres. This force is approximately the
maximum that can comfortably be applied using just the index
finger on one belt.
4. Re-fit the belt covers.
