Be extra careful when driving on slopes.
Cut slopes upwards and downwards, not sideways.
• Watch out for traffic when working close to a
road, or crossing one.
• Be careful when rounding a fixed object so that
the blades do not hit it. Never drive intentionally
over a foreign object.
• The machine is heavy and can cause very
severe crush injuries. Be extra careful when
loading it on a trailer or truck.
• Be careful when pulling a load or using heavy
equipment.
a. Only use approved tow hooks.
b. Limit the load to what you can manage safely .
c. Do not make sharp turns. Be careful when
reversing.
d. Use counterweights or wheel weights when
indicated in the instructions.
Driving on slopes
Driving on slopes is one of the situations where
there is the most serious risk that the driver can
loose control or that the machine tips over, which
can cause severe injuries or be fatal. All slopes
require extra care. If you cannot reverse up the
slope or if you feel uncertain avoid cutting it.
Do as follows:
• Remove obstacles such as stones and branches
etc.
• Cut upwards and downwards, not sideways.
• Look out for and avoid driving over furrows,
holes or mounds. On uneven surfaces it is
easier for the machine to tip over. High grass
can conceal obstacles.
• Drive slowly . Select a low gear to avoid having to
stop and changing gear. It is also easier to use
the gear to brake in a low gear.
• Follow the manufacturer’s recommendations on
wheelweights or counterweights to increase
stability .
• Take special care with accessories that can alter
the stability of the rider mower.
• Always drive smoothly and slowly on slopes.
Avoid sudden changes of speed or direction.
• Avoid starting or stopping on a slope. If the tyres
begin to skid switch of the blades and drive
slowly down the slope.
Do
not
do the following:
• Avoid unnecessary turns on slopes, and if
turning is necessary turn slowly and gradually,
downwards if possible.
SAFETY INSTRUCTIONS
Page 7
English – 5
Keep children away from the mowing area.
Never allow children to drive the machine.
Never fill up with fuel indoors.
SAFETY INSTRUCTIONS
• Do not cut close to edges, ditches or banks. The
machine can suddenly tip over if a wheel goes
over the edge of a drop or a ditch, or if a bank
gives way .
• Do not cut wet grass. It is slippery and the tyres
can loose their grip so that the machine slides.
• Do not try to stabilise the machine by placing one
foot on the ground.
• Always keep the rider mower away from edges or
ditches when cleaning the chassis.
Children
Tragic accidents can occur if the driver does not pay
attention to children in the vicinity . Children are often
attracted to the machine and the work of mowing.
Never assume that children stay where you last saw
them.
• Keep children away from the mowing area and
under the supervision of another adult.
• Be on your guard and switch off the machine if
children come into the work area.
• Before and during reversing look behind and
down for small children.
• Never allow children to ride on the machine.
They can fall off and become seriously injured or
obstruct a risky manoeuvre of the machine.
• Never allow children to drive the machine.
• Be extra careful close to corners, bushes, trees
or other objects which obstruct your view.
Maintenance
• Petrol/gasoline and petrol/gasoline fumes are
toxic and highly inflammable. Be extra careful
when handling petrol/gasoline.
a. Store the fuel in containers approved for this
purpose.
b. Never fill up the machine with fuel when the
engine is running. Let the engine cool before
filling up with fuel. Do not smoke, or fill up with
fuel in the vicinity of naked flames or sparks.
c. Never fill up with fuel indoors.
d. If leakage has occurred in the fuel system the
engine must not be started until this is rectified.
e. Never store the machine or fuel containers
indoors if there are naked flames, such as in a
boiler room or where there is electrical equipment
which can emit sparks.
• Check the fuel level each time before using the
machine, and leave space for the fuel to expand
since the heat from the engine and hot sun can
cause the fuel to run over.
Page 8
6 – English
Never smoke in the vicinity of the battery or the fuel.
Never drive the machine in an enclosed space.
Clean the machine regularly from grass, leaves and
other waste.
• Avoid overfilling. If fuel has been spilt on the
machine wipe it up and wait until it has evaporated before starting the engine. If fuel is spilt on
clothes, change them.
• Be extra careful when handling battery acid.
Spilling acid on the skin can cause severe burn
injuries. Rinse immediately with water. If acid
gets into the eyes this can cause blindness.
Contact a doctor.
• Be careful with the maintenance of the battery.
Explosive gas is formed in the battery. Never
handle the battery when smoking or in the
vicinity of naked flames or sparks. Otherwise the
battery can explode and cause severe injuries.
• Never drive the machine in an enclosed space.
The exhaust fumes contain carbon monoxide, an
odourless, non coloured, toxic and fatal gas.
• Make sure that bolts and nuts, especially attachment bolts for the blade units are properly
tightened and that the equipment is in good
order.
• Never alter the safety devices. Check regularly
that they function. The machine must not be
driven with defective or unmounted safety
devices.
• Do not alter the setting of the governor and do
not race the engine.
• Reduce the fire risk. Keep the machine clean
from grass, leaves and other refuse which
fastens in it. Allow the machine to cool before
placing it in the storage area.
• Stop and inspect the equipment if you drive over
an object. If necessary repair the machine
before starting.
• Never make adjustments with the engine running.
• The machine is tested for safety and approved
only for equipment supplied or recommended by
the manufacturer.
• The blades are sharp and can cause cutting
injuries. Wrap over the blades or use protective
gloves when handling them.
• Check the functioning of the brakes regularly .
Adjust and maintain them as necessary.
• The BioClip cutting unit should only be used to
give high quality results on lawn surfaces that
you are familiar with. If the blades of the cutting
unit strike an obstacle this could change their
spacing and lead to expensive repairs.

DRIVING
4. Push in the lock button on the lift lever and
lower down the cutting unit.
IMPORTANT INFORMATION
The service-life of the drive belts in-
creases considerably if the engine is run
at low speed when engaging the blades.
For this reason do not increase the throttle until the cutting unit has been lowered
to the cutting position.
!
WARNING!
Clear the lawn from stones and
other object which can be thrown
out by the blades.
Cutting tips
• Localise and mark stones and other fixed
objects to avoid collision.
• Start with a high cutting height and reduce down
until the required cutting result are obtained.
• The cutting results are best with a high engine
speed (fast rotating blades) and low driving
speed (slow moving machine). If the grass is not
too high and thick the driving speed can be
increased or the engine speed reduced without
noticeably affecting the mowing results.
• The best lawns are achieved if the grass is cut
often. This is especially important when mowing
with a Mulcher unit. Mowing becomes more
uniform and the grass cuttings become more
evenly distributed over the surface. The total
time consumption is not greater since it is
possible to select a higher driving speed without
inferior mowing results.
• Avoid mowing a wet lawn. The mowing results
are inferior since the wheels sink down into the
soft lawn.
• Wash down the underside of the cutting unit with
water after use. Do not use a high pressure jet.
Put the cutting unit in the service position while
doing this.

To achieve the best cutting results the cutting unit
should follow the underlying surface without pressing too hard against it.
The pressure is adjusted with a screw on each side
of the machine.
1. Place a set of bathroom scales under the cutting
unit’s frame (front edge) so that it rests on the
scales. If necessary a block can be placed
between the frame and scales so that the
support wheels do not bear any weight.
2. Adjust the unit’s ground pressure by screwing in
or out the adjusting screws located behind the
front wheels on both sides.
The ground pressure should be between 12 and
15 kg.
Checking the cutting unit’s parallelism
Check the parallelism of the cutting unit as follows:
1. Place the machine on a level surface.
2. Measure the distance between the ground and
the front and rear edges of the cutting unit hood.

Lubrication
The following two lubrication points should be
regularly lubricated with high quality graphite
grease.
With daily use lubrication should be conducted
twice a week.
General lubrication
All joints and bearings are lubricated on manufacture with molybdenum sulphide grease. Re-grease
with same type of grease. Lubricate the steering
and control wires with engine oil.
The machine should be lubricated regularly, and
twice a week when used daily.
Checking the tyre pressure
The tyre pressure should be 60 kPa (0.6 kp/cm2) all
round.
To improve driving the pressure on the rear tyres
can be reduced to 40 kPa (0.4 kp/cm2).
The maximum tyre pressure is 100 kPa (1.0 kp/cm2).
IMPORTANT INFORMATION
Different tyre pressures on the front tyres
will result in the blades cutting the grass
at different heights.

MAINTENANCE
Changing the oil
The oil should be changed for the first time after 5
hours of running time. Thereafter it should be
changed every 25 hours of running time.
WARNING!
Engine oil can be very hot if it is
drained off directly after the
engine is stopped. Therefore allow
the engine to cool down first.
!
IMPORTANT INFORMATION
Used engine oil is hazardous to health and
environment and must in accordance with
the law not be poured out on the ground
or in the nature, and must be handed in to
a workshop or other designated station for
treatment. Avoid skin contact, wash with
soap and water in the event of spillage.
5. Fill up with oil to the FULL mark on the dip stick.
The oil is filled in the same hole for the dip stick.
Use engine oil SAE 30 or SAE 10W/30, class
CD-SF.
Use engine oil with min. API SF quality and SAE
30 or SAE 10W/30 viscosity grade. The oil
volume in the engine is 1,4 litres.
6. Run the engine warm and then check that there
is no leakage from the drain plug.
1. Place a receptacle under the engine’s drain
plug, located on the left-hand side of the engine.
2. Remove the dip stick and drain plug.
3. Let the oil run out into the receptacle.
4. Fit the drain plug and tighten.

MAINTENANCE
Checking and adjustment of the
throttle wire
If the engine does not respond as it should do when
the throttle lever is moved or if the top speed is not
reached, the throttle wire may need adjusting.
1. Release the clamping screw (see arrow) and
push the throttle control to full throttle position.
Replacement of the fuel filter
Replace the pipe fitted fuel filter every 100 running
hours (once per season) or more frequently if it is
clogged.
Replace the filter as follows:
1. Dismantle the engine hood as described on
page 17.
2. Move the hose clips away from the filter. Use a
pair of flat pliers.
3. Pull off the filter from the hose ends.
4. Press in the new filter on the hose ends. If
necessary soap solution can be applied on the
filter ends to simplify fitting.
5. Push the hose clips back on the filter.
2. Pull the throttle wire’s outer casing to the far
right and tighten the clamping screw.

Winter storage
At the end of the season the machine should
immediately be put in order for storage, also if it is
going to stand idle for more than 30 days. Fuel
which is left to stand for long periods (30 days or
more) can leave tacky deposits which can block the
carburettor and interfere with the engine.
Fuel stabiliser is an acceptable alternative to avoid
tacky deposits during storage. If alkylate petrol
(Aspen) is used stabiliser is not necessary since
this fuel is stable. However, one should avoid
changing from standard to alkylate petrol since
sensitive rubber parts can harden. Add stabiliser to
the fuel in the tank or the storage container. Always
use the mixing ratios indicated by the manufacturer.
Run the engine for at least 10 minutes after adding
the stabiliser so that it will reach the carburettor. Do
not empty the fuel tank and carburettor if stabiliser
has been added.
STORAGE
WARNING!
Never place an engine with fuel in
the tank indoors or in poorly
ventilated areas where petrol fumes
can come into contact with naked
flames, sparks or pilot flames in
boilers, hot water heaters, or
drying cabinets, etc. It is highly
inflammable and negligent usage
can cause severe person injury
and material damage. Drain off
the fuel in an approved container
outdoors and well clear of naked
flames. Never use petrol for cleaning
purposes. Use degreasing agents
and hot water instead.
To put the machine in order for storage follow these
instructions:
1. Carefully clean the machine, especially under
the cutting unit. Touch-up paint damage to avoid
rust.
2. Inspect the machine for worn or damaged parts
and tighten loose screws and nuts.
3. Change the oil, and take care of the waste oil.
4. Empty the fuel tank. Start the engine and run it
until the carburettor is emptied of fuel.
5. Remove the plug and pour in a tablespoon of
engine oil in each cylinder. Pull round the engine
to distribute the oil and screw the plug back on.
6. Grease all grease nipples, joints and axles.
7. Remove the battery. Clean it, charge it, and
store it is a cool place. Protect the battery from
low temperatures (below freezing point).
8. Store the machine is a clean and dry place and
cover it over for extra protection.
Service
When ordering spare parts state the purchase year,
model, type, and serial number.
Always use genuine parts.
Annual inspection or trimming by an authorised
service workshop is a good way of getting the best
out of your machine the next season.
