B) CUTTING DISCS): They should be checked regularly! (Especially
check the screw tightening torque.) The tightening torque equals 7.5
daNm.
- Perform a check immediately after hitting a hidden obstacle.
- Perform a check when replacing the blades.
Always mount two blades of the same type onto a cutting disc, in
order to avoid unbalancing the disc.
Perform a check prior to every mowing season.
1. You must replace the blade carrier in the following cases:
- When there are visible deformities.
- When the head gets worn at the blade contact area.
- When the nominal circumference of the blade carrier
Dn = 16 mm reaches a maximum value on the worn blade
carrier of D = 13 mm.
2. You must replace the nut in the following cases:
- When the contact protective mass in the nut loses elasticity,
which is characterised by frequent loosening.
- When the wearing of the nut reaches a value of a = H/2.
6.2 V-belts
The V-belts must be properly tightened in order to prevent excessive
slipping. Insufficiently tightened belts cause the cutter bar to oper-
ate badly and to damage and tear prematurely.
In order to tighten the belt, loosen the nuts (A) (figure 52). Tighten
the nut (B) until the force of 9 daN is achieved, i.e. the deflection of 10
mm between the belts. While doing that, make sure that the casing
fits the frame properly. Finally, tighten the nuts (A).
NOTE:
CHECK THAT THE BELTS ARE STILL TIGHT AFTER THE FIRST
1/2 HOUR OF USE. WHEN REPLACING THE WORN-OUT BELTS, RE-
PLACE THE ENTIRE SET OF BELTS, REGARDLESS OF THE CONDITION
OF ONE BELT COMPARED TO OTHERS
6.3. Oiling
It very important to properly oil the transmission components in
order to fulfil the strict requirement for working even in the most
difficult conditions. It is best to release the oil immediately after fin-
ishing with work, since the oil is still warm then, and the residue has
still not settled.
NOTE:
THE LISTED TIMES FOR OILING ONLY REFER TO NORMAL
WORKING CONDITIONS. IF YOU ARE WORKING IN MORE DIFFICULT
CONDITIONS, MORE FREQUENT OILING IS NEEDED.
CAUTION!
USE OIL OF THE REQUIRED QUALITY
IN ORDER TO AVOID DAMAGE TO THE MACHINE. BY
PROPER AND REGULAR OILING YOU WILL ENSURE UN-
IMPEDED AND SAFE OPERATION.
CAUTION!
THE OIL IN THE TORQUE MULTIPLIER
AND CUTTER BAR MUST NECESSARILY BE CHANGED
AFTER THE FIRST 8 HOURS OF OPERATION. ONLY USE
SAE 80 W EP OIL.
