USING THE MACHINE

CUTTING HEIGHT
AMM 842:
The cutting height can be varied between a number
of fixed positions, from 30 to 85 mm.
AME 842:
The cutting height is continuously variable from
30 to 85 mm.
Note: Stated cutting heights apply when the ma-
chine is on a firm surface.
CUTTING TIPS
For optimum 'Multiclip effect', follow these tips:
- cut frequently.
- run the engine at full revs.
- keep the underside of the cutting deck clean.
- use sharp blades.
- do not cut wet grass.
- cut twice (with different cutting heights) if
the grass is long.

SERVICE AND MAINTENANCE

PREPARATIONS
Unless otherwise stated, all service and mainte-
nance must be carried out on a stationary machine
when the engine is not running.
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the
engine by always stopping the engine,
disconnecting the spark plug cable
from the spark plug and earthing it.
Disconnect the negative cable from the
battery.
MAINTENANCE TIPS
To make cleaning and maintenance easier, the cut-
ting deck can be folded up:
1. Set the cutting height setting to the maximum
cutting height.
2. Lift the rear edge of the deck with one hand (fig.
10).
3. Push up the catch and release the rear edge of the
ENGLISH
deck (fig. 10).
4. Repeat the procedure on the other side.
5. Hook the belt idler arm on the mount (fig. 11)
6. Force the belt off the centre pulley.
7. Fold up the deck to the vertical position (fig. 12).
When the deck is folded down to working position,
ensure that the catch drops down into position
when the rear edge of the deck is lifted up (fig. 4).
CLEANING
After each use, the underside of the cutting deck
should be rinsed off.
If the grass has dried solid, scrape clean the under-
side.
If necessary, touch up the underside with paint to
prevent corrosion.
BLADES
Use protective gloves when changing
blades to avoid cutting yourself.
Ensure that the blades are always sharp. This pro-
duces the best cutting results.
Always check the blades after a collision. If the
blade system has been damaged, defective parts
should be replaced.
Always use genuine spare parts. Non-
genuine spare parts can entail a risk of
injury, even if they fit the machine.
Install the blades according to fig. 13 where the
blade edge is marked. The folded-up edge of the
blade should be positioned inwards towards the
blade holder.
The cutting system comprises two blade bars with
two replaceable blades Y (fig. 14). When replacing
blades, both should be replaced to avoid imbal-
ance.
Install the new blades. Tighten screws V and W
properly. Tightening torque: V - 9.8 Nm, W - 24
Nm.
In the event of a powerful collision, the blades may
be bent out. Undo the locking nut X and fold back
the blade. Install a new genuine break bolt V.
Tighten the locking nuts X and Z.
