• 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.
• Avoid unnecessary turns on slopes, and if
turning is necessary turn slowly and gradually,
downwards if possible.

• 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.
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 close 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.
Keep children away from the mowing area.

• Avoid overfilling. If fuel has been spilt on the
Rider 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 smoke in the vicinity of the battery or the fuel.
• 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.

Throttle and Choke lever
The engine speed is adjusted with the throttle
control, and thereby also the rotation speed of the
blades.
The control is also used to activate the choke
function. When the choke is used the engine
receives a richer mixture of fuel and air, which
simplifies cold start.
Clutch pedal
The clutch pedal disengages the engine and stops
forward movement.
The blades are
not
affected by the clutch pedal.
Brake pedal / Parking brake
The brake pedal activates a disc brake which is
placed on the gearbox and brakes the drive wheels.
When braking the clutch pedal should also be
pushed down to achieve best braking power.

3. Select the required cutting height (1-9) with the
cutting height lever.
To obtain a uniform cutting height it is important
that the tyre pressures are equal on both front
wheels (60 kPa).
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 increases
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.
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. 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.
• Hose down the cutting unit with water
underneath each time it is used. Put the cutting
unit in the service position first.
• If you use the BioClip unit it is important to mow
the grass regularly.
WARNING!
!
Clear the lawn from stones and other
object which can be thrown out by the
blades.

STORAGE
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.
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 spark plug and pour about a tablespoon of engine oil into the 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.
8. Store the machine is a clean and dry place and
cover it over for extra protection.
!
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.
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.
