Before starting work, remove all foreign objects such as
stones, glass, cables, metal objects and other loose ob-
jects.
The following symbols can be found on the tiller. Their pur-
pose it to remind you of the care and attention required when
using it. If any symbol is missing, damaged or unreadable, it
should be immediately replaced with a new one. The sym-
bols mean:
•
•
•
Toys, hoses and other objects can be damaged.
Check that the tiller is in good condition before using it.
Check that all nuts and bolts are tightened.
1. Warning! Read the instructions.
2. Warning for rotating blades.
3. Reverse gear.
2.3 OPERATING
•
•
•
•
•
•
Always operate the machine at low speed when working
on stony ground.
4. Clutch handle. Handle out, left fig. = disengaged. Handle
pressed in, right fig. = engaged.
Do not change the engine's speed setting. The engine
must not be overspeeded.
5. Throttle control, a=fast, b=slow and c=stop.
The work area should be well illuminated during the
work.
6. Read the instructions and remove the spark plug lead be-
fore doing any work. Wear protective gloves.
The tiller must not be used when other persons, especially
children, are in the vicinity.
2 SAFETY INSTRUCTIONS
The tiller must not be used without the splashguards or
protective cover.
2.1 GENERAL
The tiller must not be used if the operator is ill, has taken
medicine, or is under the influence of other substances
which reduce one's reactions.
•
Read through this instruction book carefully and make
sure you understand the contents before using the tiller.
•
•
•
The tiller must only be used for gardening purposes.
Keep children away from the tiller.
•
•
The tiller must not be used on terrain which slopes more
than 20°.
Do not allow children or persons who have not read the
instructions to handle the tiller.
The user is responsible to ensure that all risks in the ter-
rain are taken into consideration, and that procedures are
taken to prevent accidents. This particularly applies to
sloping, slippery or loose terrain.
•
The tiller is manufactured in accordance with current
standards, and must not be modified or rebuilt.
•
•
All the symbols on the tiller should be kept intact.
•
Start the engine carefully, according to the instructions in
this manual. No parts of the body must come in contact
with the rotors.
The user is liable for damages incurred by a third party.
WARNING for petrol. Petrol is highly inflamma-
ble: Petrol must be stored in the requisite contai-
ners.
•
•
The engine must never be started in an enclosed area.
The carbon monoxide in the engine's exhaust fumes is
poisonous and can cause death.
•
•
•
Always fill-up outdoors and with the engine switched off.
Do not smoke when filling-up.
•
•
•
Wear tightly fitting clothes and heavy-duty shoes which
completely cover the feet.
There must be no naked flames or other sources of heat in
the vicinity of the petrol.
The tank should only be half full when operating on slo-
pes. Petrol can leak out.
•
Do not start the engine if petrol has spilled out. Move the
machine and allow the petrol to evaporate before starting
the machine.
The engine must be stopped in the following circum-
stances:
•
•
•
When the machine is left unattended
•
•
Screw on the filler cap correctly after filling up.
Before the machine is filled up with petrol
Set the throttle control in the "Stop" position, and close
the petrol cock when the machine has been stopped.
Always make sure you have a good footing, especially on
slopes.
•
Switch off the engine before transporting the machine.
Never lift the machine by yourself. The machine is lifted
by two persons, one on each side holding the steering and
the rotor axle. Wear protective gloves and hold the machi-
ne upright when lifting.
•
Check that no one is in front of you or beside you when
starting the blades. Keep a steady grip on the steering.
The machine will lift when the rotors are started. Use ex-
tra caution when backing.
•
When the machine is loaded on a trailer or tailboard it
should be run up on a ramp by using its wheel.
EN
ENGLISH
•
Always keep at a safe distance to the rotors when wor-
king.

5 ASSEMBLY
3 DELIVERY
5.1 STEERING, SEE FIG. 4
The tiller is delivered in a box with the steering and side pla-
tes dismantled. All the wires are fitted and adjusted.
Fit the steering (1) according to the figure with the bolt (2),
washer (3), nut (4), bolt (5), washer (6) and nut (7). Choose
a suitable hole for the bolt (5) for comfortable adjustment of
the steering (1).
WARNING! There is no oil in the engine on
delivery.
5.2 SPLASHGUARD, SEE FIG. 2
Fit the splashguards (6) on both sides with the enclosed nuts
and bolts.
EN
ENGLISH
5.3 SUPPORT WHEEL, SEE FIG. 5
6.3 FORWARD OPERATION, SEE FIG. 2.
Fit the support wheel according to the figure. Do not tighten
the nut (5) too hard. It will not be possible to fold the wheel
arm up.
Forward gear is selected when the left handle, the gear con-
trol (2), is not pushed in. The tiller starts forward when the
clutch handle (1) is pulled in. Go forwards as follows:
1. Set the throttle control (10) in the required position.
5.4 FILLING THE OIL, SEE FIG. 2
2. Pull in the clutch handle (1). The tiller stops moving for-
ward when the clutch handle (1) is released.
Remove the plug (12) and fill up with 0.7 L of oil, SAE
10W40. Screw the plug back on.
6.4 BACKWARD OPERATION, SEE FIG. 2
5.5 ROTORS AND SIDE ROLLERS, SEE FIG. 6
WARNING! The gear control (2) must only be pul-
led in when the clutch handle (1) is not pulled in.
The first rotor (1) is pushed on the axle shaft (2) and locked
with the cotter (3). After which the second rotor (4) is inser-
ted in the first and locked with the cotter (3). Max. 3 rotors
can be fitted in this way on each side. Finally, fit the side rol-
lers in the same way.
Go backwards as follows:
1. Set the throttle control (10) in the required position.
2. Pull in the gear control (2).
WARNING! Check that the cotters are locked,
3. Pull in the clutch handle (1). The tiller stops moving
backwards when both handles are released.
i.e. that the springs are locked round the shaft.
6.5 STOPPING, SEE FIG. 11
Stop the tiller as follows: 1 Set the throttle control in stop po-
sition. See fig. 11a 2 Set the choke lever in choke position.
See fig. 11b. 3 Close the petrol cock. See fig. 11c.
6 OPERATING
See also section 2.3.
6.6 OPERATING TIPS
WARNING! Check the engine's oil level. See sec-
tion 8.4.
The rotors drive the machine forward. The speed of the rotors
is regulated with the throttle control.
6.1 FILLING THE FUEL, SEE FIG. 7
WARNING! Keep hands and feet away from the
rotors.
See the safety instructions in section 2.1. Fill up with 2.8 L
of unleaded petrol, and screw on the filler cap.
Adjust the number of rotors on each side to the required wor-
king width. See section 5.5.
NOTE! Remember that standard unleaded petrol is perisha-
ble. Do not buy more petrol than what can be consumed in 30
days. Environmentally adapted petrol (acrylic petrol) can be
used to advantage. This petrol is more environmentally-fri-
endly.
When the machine is braked with the help of the tail brake,
the rotors dig down into the earth. The working depth de-
pends upon how much the tail brake is forced down into the
ground while working. The correct working depth determi-
nes how easily the work is done. The optimal working depth
varies with the ground conditions. Try it and see.
6.2 START
See the safety instructions in section 2.3. A cold engine is
started as follows:
Never use the machine in wet soil. Lumps form, which are
then difficult to crush. Hard and dry soil necessitates making
a second run, at right angles to the first.
1. Open the petrol cock. See fig. 8.
WARNING! Never overload a new machine. Run
the machine carefully the first 5 hours.
2. Set the choke lever in the choke position. See fig. 11b.
3. Set the throttle control to idle. See fig. 10.
4. Pull the starter handle, first gently until the pawls grip,
and then with a strong tug until the engine starts. See (5)
in fig 2.
7 STORAGE
NOTE! Do not let go of the cord when the engine has
started, but follow it back slowly with your hand!
The tiller should be stored in a dry place.
See also section
5. Set the throttle control in mid position.
2.4.
6. Set the choke in position "Run". See fig 9. A warm engine
is started in the same way as above, but without steps 2
and 6.
After the petrol has been drained off, start the engine and al-
low it to run until all the remaining petrol is used up.
