SYMBOLS
The following symbols appear on the machine.
They are there to remind you of the care and attention required in use.
This is what the symbols mean:
Warning!
Read the instruction manual and the safety
manual before using the machine.
Warning!
Do not insert your hands or feet under the
cover when the machine is in operation.
Warning!
Watch out for discarded objects. Keep onlookers away.
Warning!
Before starting repair work, remove the
spark plug cable from the spark plug.
ASSEMBLY
DECK ARMS
1. Install the left and right deck arms in the cutting
deck’s front two corners. Use the existing screw
and flat washer (fig. 1). Tighten the screw. After
tightening, it should be possible to move the deck
arms up and down.
2. Do not hook the rear part of the deck arms onto
the deck yet (See “Cutting deck” point 4 below).
5. Tension the belt with the belt idler. The belt idler
should be on the left side of the belt viewed from
the driver's position (fig. 6).
6. Secure the lift spring in the implement lifter (fig.
5).
SETTING
In order for the deck to cut evenly and attractively,
it has to be correctly adjusted:
1. Make sure the air pressure in the tyres is correct:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi).
2. Place the machine on a level floor. Undo the
screws on either side of the deck (fig. 7).
3. On the side of the deck arm are four short and
two long lines. The upper long line (A) is the basic
setting for a machine with 16” tyres (fig. 8).
Depending on the length of the grass, the deck can
be adjusted in various ways:
4a. Cutting normal length grass:
Adjust the deck so that the front and rear edge of
the cover are the same height above the floor. This
position gives the best ‘Multiclip effect’, i.e. the
grass is cut up best.
4b. Cutting long grass:
Adjust the deck so that the cover’s rear edge is
higher than the front edge. This position means
that the deck can release the grass more easily at
the rear edge.
5. After setting, tighten the screws properly.
USING THE MACHINE
CUTTING DECK
CUTTING HEIGHT
1. Place the cutting deck in front of the machine.
Set the maximum cutting height.
The cutting height can be varied between a number
of fixed positions, from 30 to 85 mm.
2. Thread one of the deck arms onto the machine’s
steering knuckle (fig. 2-3). Place the flat washer on
the steering knuckle and secure with a locking pin.
Repeat on the other side.
Note: Stated cutting heights apply when the machine is on a firm surface.
3. Force the V-belt onto the machine’s centre pulley (fig. 6).
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
4. Lift up the deck’s rear part past the catch until it
drops down. When the weight of the deck is resting
on the upper side of the catch, the installation is
correct (fig. 4).

SERVICE AND MAINTENANCE
PREPARATIONS
Unless otherwise stated, all service and maintenance must be carried out on a stationary machine
when the engine is not running.
Prevent the machine from rolling by always 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 cutting 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.
9).
BLADES
Use protective gloves when changing
blades to avoid cutting yourself.
Ensure that the blades are always sharp. This produces 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. Nongenuine spare parts can entail a risk of
injury, even if they fit the machine.
Install the blades according to fig. 12 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. 13). When replacing
blades, both should be replaced to avoid imbalance.
Install the new blades. Tighten screws V and W
properly. Tightening torque: V - 9.8 Nm, W - 24
Nm.
3. Push up the catch and release the rear edge of the
deck (fig. 9).
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.
4. Repeat the procedure on the other side.
POSITIVE DRIVE BELT
5. Hook the belt idler arm on the mount (fig. 10)
Both blades are powered inside the deck by a positive drive belt.
6. Force the belt off the centre pulley.
7. Fold up the deck to the vertical position (fig. 11).
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 underside.
If necessary, touch up the underside with paint to
prevent corrosion.
If one of the blades has struck a solid object (e.g. a
stone), the belt tension may be altered. This can
lead to the positive drive belt ‘over-meshing’
which, in the long term, can damage the blades.
Following a powerful collision, always
check that both blades are at right-angles to each other (fig. 12).
The working areas of the blades overlap each other. If the blades’ position in relation to each other
has been altered, there is a considerable risk of the
blades striking each other. This can entail serious
damage to the cutting deck.
If this is the case, take the machine and cutting
deck to a service workshop for repair and inspection.
