2.1 Safety instructions
Working on the machine does not usually represent a specific hazard. An exception is the work that involves
mechanical components. These activities should be carried out with the caution and attention that is usual
for this type of work.
In addition to observing the usual accident-prevention regulations that are typical for all mechanical
workshops,we recommend:
Carry out maintenance, service and repair work only when the engine is switched off and cool.
Prior to starting work, remove the ignition key and disconnect the negative terminal of the battery.
Wear suitable protective gloves when you handle blades and sheet-metal parts.
Avoid petrol leaking. Wipe up leaked petrol.
Smoking prohibited in the vicinity of engine and tank.
Secure the tractor such that persons cannot be injured from inadvertent actions.
CAUTION!
Workshop manual
Risk of accidents!
Observe the safety instructions in the operating and engine instructions,and the safety
instructions on the unit.
Trailer:
The total weight of a trailer pulled by the tractor should not be higher than 50% of the tractor
weight including driver. For this tractor, the total weight of the trailer should not be higher than
250 kg.
The maximum towed and drawbar load is 40 kg.

3 Maintenance and care
3.1 Maintenance table
Caution!
Risk of accidents!
Carry out maintenance, service and repair work only when the motor is switched off and cool.
Prior to starting work, remove the ignition key and disconnect the negative terminal of the
battery.
1)
See the operating instructions from
the engine manufacturer
With high stress and at high temperature reducing the
specified maintenance intervals may be necessary.

Page 8
3.2 Lubricating plan
3.2.1 Front axle
WARNING!
To ensure the smooth operation of moving parts, we recommend lubricating the following
points every 50 operating hours / once a year.
Lubricate the steering-axle stubs right and left
(lubricating nipples) with multi-purpose grease.
Spray the front axle bearings on the frame with oil.
Lubricate the ball heads with multi-purpose grease.
Remove the ball caps before you start lubrication
(See steering sector disassembly).
Workshop manual
3.2.2 Steering
Grease toothing and bearing surface of the gear
segmentwith multi-purpose grease.
Grease the pinion.
3.2.3 Front and rear wheels
Lubricate roller bearings / hubs with multi-
purpose grease.
Remove the front and rear wheels before you start
lubricating the axles.
Ensure that the driving key is in place when you
install the rear wheels

Page 9
Workshop manual
3.2.4 Tensioning pulley rocker / pivoting and bearing points
Tensioning pulley rocker (mowing implement):
Spray pivoting and bearing points with oil.
Pivoting and bearing points:
Spray all pivoting and bearing points and the
pivoting points of the ropes with oil.
3.3 Oil change
CAUTION!
See also operating instructions from the engine manufacturer.
Use an oil drain extension to change oil conveniently.
Have a suitable collecting container ready.
Remove the 19-mm screw plug. Hold the oil drain
extension with a fork spanner to prevent it from
being screwed out of the engine.
CAUTION!
Dispose of the used oil in accordance with
the legal regulations
Never drain used oil into the sewerage
system or the soil.
There are high fines on groundwater
pollution.
You can deliver used oil to any petrol station,
or get the address of a disposal company
from the local authorities.
Alternatively, you can suck off the oil through
the oil filler neck.
3.4 Air filter / spark plug
CAUTION!
See also operating instructions from the engine manufacturer.

Page 10
3.5 Tyre pressure
Check the tyre pressure at regular intervals..
Tyre pressure recommended: 0,9 - 1,0 bar
3.6 Hydrostatic transmission
Use a cloth, hand brush, long-handled paintbrush and compressed air to remove dirt and grass residues.
Check the oil level during the yearly service. Top up oil if necessary. (Engine oil 20W50)
Workshop manual
CAUTION!
See also operating instructions from the engine manufacturer.
Start-up after transmission repair
To ensure proper operation and full performance of the transmission, bleed the transmission
before the first start-up of the tractor.
This ensures that all air bubbles are removed that could have formed in the gearbox during the
transport of the tractor.
Procedure
Park the tractor on a level surface and ensure that is
remains in place
Do not apply the parking brake for this process.
Actuate the bypass lever to disengage the transmission.
For 95 - 105 transmission:
Pull out the bypass lever and secure it in the
upper position
10
Page 11
Workshop manual
For 125 transmission:
Push in the bypass lever and secure it in the
upper position
Sit on the operator's seat
Start the engine and set the throttle to medium speed.
The parking brake remains released
Press the forward accelerator pedal (a) for five seconds
Press the rearward accelerator pedal (b) for five
seconds.
Repeat this procedure 3 times.
Set the throttle to idle position.
Set the bypass lever back to drive.
Drive the tractor 1.5 m forward and back. Repeat this
procedure 3 times.
➯ The tractor is now operational
.
3.7 Start battery (12V / 17 Ah)
The starter battery sits under the bonnet.
For winter storage, store the starter battery in a cool and dry place (10°C - 15°C).
Avoid storing the battery at temperatures below freezing point.
Recharging the starter battery during a long storage period is recommended.
CAUTION!
The starter battery should not:
Be stored in the immediate vicinity of a
naked flame
Incinerated
Be put on a radiator
WARNING!
Risk of explosion
Never short-circuit the connection terminals.
Keep the starter battery clean. Wipe it only with a dry cloth.
Do not use water, petrol, thinners or the like for this purpose!
Keep the connection terminals clean and grease them with terminal grease.
11
Page 12
Workshop manual
CAUTION!
Damaging the display
Never disconnect the starter battery while the engine is running.
Never start the tractor with external power supply.
Charging the starter battery
Charging is required:
Prior to storing for the winter break.
During extended standstill of the machine (longer than 3 months).
DANGER!
Risk of explosion!
The charging current of the charger must not be higher than 5 A and e the maximum permitted
charging voltage is 14.4 V.
We recommend charging the maintenance-free and gas-tight starter battery with a
compatible charger.
Charge the starter battery only in a dry room.
Observe the operating instructions for the battery charger.
Remove the ignition key.
Open the engine cover.
CAUTION!
Danger of short circuit!
Ensure that the polarity is correct.
Red terminal = positive pole (+)
Connect the charger terminals to the battery poles.
Connect the charger to the mains, and switch it on.
Black terminal = negative pole (-)

4.3.2 Replacing the blade
WARNING!
Risk of injuries - cutting
Always wear protective gloves when you handle the blades.
Wear protective goggles when you sharpen the blade.
Unscrew the 17-mm hexagon head screw, and

Tightening torque: 65 Nm
A blunt blade has a negative effect on the mowing performance and the appearance of the cut lawn. A poorly balanced
blade causes excessive vibrations during operation. A poorly balanced blade can damage the unit.
Sharpening:
Always sharpen both edges of the blade with a
grinding disc of medium grade.
Always sharpen at the bordered side so that only a
minimum of material is removed.
A blade must be replaced when the wear of the blade
reaches 10 mm.
21
Page 22
Balancing:
Use a suitable measuring instrument to measure the
imbalance. Adjust until the difference between the two
blades is no more than 2 g.
