ADJUSTMENT OF COMPENSATING
SPRING TENSION
The compensating springs are factory adjusted so that
dimension (X) (photo 25) is 30 mm (1 1/3") for the GMD
802 F, 50 mm (2") for the GMD 702 F, 70 mm (2 2/3")
for the GMD 602 F, .
When working conditions are difficult, adjustment can
be modified as follows :
- Put machine in transport position, which releases
compensating springs (P) (photo 25).
- Loosen lock nuts (H) and adjust screws (F).
- After adjustment retighten lock nuts (H).
- Both springs must be adjusted at the same length
(X).
To park the machine when in transport or working position, proceed as follows :
- Lock the manoeuvring lever (L) in the rear notch (R ) of the selector plate to engage the parking latches (D) (photo
26A).
- Using levers (K) lower the transport locks (J) towards the rear and secure them in place (photo 26). To facilitate
this pressurise the cylinders,
- Check that the parking latches (D) butt against the cylinder rods. If necessary, to allow latches engagement, lower
the machine,
- Lift the machine using the tractor lift linkage,
- Detach the check chains (G) and remove the R-clip (E) (photo 27),
- Uncouple the PTO shaft (T) (photos 27 and 27A),
- Lower the machine onto the ground until the parking latches (D) butt against the cylinder barrels,
- Uncouple the A frame (A) and disconnect the hydraulic hose (H) photo 27).
