height positions
- art. no. 13-2921 has stepless adjustment of the
mowing height.
N.B. The stated mowing heights apply when the
machine is standing on firm ground.
MOWING HINTS
For the best "Multiclip" effect follow this advice:
- mow regularly.
- use full throttle on the engine.
- keep the underside of the mower deck clean.
- use sharp blades.
- do not mow wet grass.
- mow twice (using different mowing heights)
if the grass is long.
MAINTENANCE
PREPARATIONS
Unless otherwise stated, all service and mainte-
nance must be performed on a machine that is
standing still where the engine has been switched
off.
Prevent the machine from rolling, by al-
ways applying the parking brake.
Prevent involuntary engine start by al-
ways stopping the engine, loosening the
spark plug cable from the sparking
plug and earthing it. Remove the minus
(-) cable from the battery.
MAINTENANCE TIPS
To facilitate cleaning and maintenance of the
mower deck it can be folded up:
1. Set the mowing height adjustment to an interme-
diate position (= least tension on the drive belt).
2. Lift up the mower deck using the attachment lift.
3. Unhook the tension roller spring H (fig 7).
4. Pull off the v-belt from the central belt pulley F.
5. Loosen both locking pins J (fig 9).
6. Grip the mower deck's frame (fig 10).
7. Fold up the mower deck until it stands upright
on the rear support plates (fig 11).
CLEANING
After use the underside of the mower deck should
be hosed down.
If grass cuttings have dried on to the mower deck,
scrape the underside clean.
If necessary touch-up the underside using a suita-
ble paint to prevent corrosion.
DRIVE BELTS
If any of the blades have hit a solid object (e.g. a
stone) the belt tension can change. This means that
the drive belt can, "miss-mesh" which in the long
term can damage the blades.
If necessary adjust the drive belt:
1. Unhook the tension roller spring H (fig 7).
2. Pry off the drive belt from the central belt
pulley F.
3. Dismantle the transmission casing.
4. Loosen the tension arm K (fig 12).
5. Loosen the bearing box's fixing bolts L (fig 13).
6. Tension the drive belt by pressing the tension
arm backwards.
7. Tighten the tension arm's fixing bolts.
8. Tighten the bearing box's fixing bolts.
9. Carry out the same procedure for the other drive
belt.
When changing the drive belts, make
sure that the outer blades are always at
90° to the centre blade (see fig 14).
If you fit the drive belts incorrectly the blades will
collide as they overlap each other.
Always check the position of the blades after
changing the drive belt or adjusting the tension.
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.
