CLEANING
After use, rinse off the underside of the mower
deck using a garden hose.
If grass cuttings have dried on to the attachment,
dismantle the mower deck and scrape clean the un-
derside.
If necessary touch-up the underside using a suita-
ble paint to prevent corrosion.
CHANGING THE DRIVE BELT
1. Remove the mower deck from the base machine.
2. Remove the transmission casing.
3. Loosen the tension arm L (fig 8).
4. Loosen the right hand bearing box's fixing bolts
M (fig 9).
5. Fit the new drive belt.
Thenewdrivebeltmustbefittedsothat
the blades are square (90°) to each oth-
er. See figure 10. If you fit the drive belt
incorrectly the blades will hit each oth-
er resulting in the blades being dam-
aged.
6. The belt is tensioned by pushing the tension arm
L forwards and then securing in position.
7. Tighten the bearing box's fixing bolts M.
When the drive belt is fitted, check, by
turningthemowerdeckoverandturn-
ing the blades, that it has been fitted
correctly. NOTE! The mower deck
should be dismantled from the base ma-
chine.
8. Now refit the mower deck on the base machine.
CHANGING BLADES
Use protective gloves to prevent cuts
when changing blades/blade tips.
Make sure the blades are always sharp. This gives
the best mowing results.
Always check the blade(s) after an impact. If the
blade system has been damaged the defective parts
must be changed.
Always use original spare parts. Using
non-original spare parts can result in
the risk of damage even if they fit in the
machine.
The cutting system consists of two blade bars, each
with two interchangeable blade tips Y (fig 11).
Both blade tips should be replaced at the same time
to avoid any imbalance.
Fit the new blade tips. Tighten the screws V and W
fully. Tightening torque: V - 9.8 Nm, W - 24 Nm.
And heavy impact can result in the blade tip being
folded aside. Loosen the locking nut X and turn the
blade tip back to its correct position. Mount a new
shear bolt V. Tighten the lock nuts X and Z.
