SAFETY INSTRUCTIONS
• 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 .
• Be extra careful with the grass collector or other
equipment which can alter the stability of the
machine.
• 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.

Be extra careful when driving on slopes.
Cut slopes upwards and downwards, not sideways.
4 – English
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.
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.
Keep children away from the mowing area.

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.
Never allow children to drive the machine.

SAFETY INSTRUCTIONS
• 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 parts on the grass collector can become
worn, damaged and aged, so that moving parts
are exposed or so that an object can be thrown
out. Check the parts regularly and if necessary
replace them with spare parts recommended by
the manufacturer.
• 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.
Never smoke in the vicinity of the battery or the fuel.

Rider 850 and Rider 970.
Both models are fitted with engines from Briggs &
Stratton of 12.5 and 15.5 h.p. respectively .
The power transmission from the engine is handled
by a hydrostatic gear box which enables stepless
variation of the speed with the foot pedals.
There is one pedal for driving forwards and one
pedal for reversing.

PRESENTATION
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.
Speed limiter
The speed of the machine is steplessly regulated
with two pedals. Pedal (1) is used to drive forwards
and pedal (2) for reversing.

Parking brake
The parking brake is applied as follows:
1. Press down the brake pedal.
2. Press in the lock button on the steering column.
3. Release up the brake pedal while holding the
button pressed.
The lock on the parking brake automatically disconnects when the brake pedal is pressed.

PRESENTATION
Cutting unit
Rider 850 has a cutting unit with rear ejection, i.e.
the grass cuttings are thrown out behind the cutting
unit.
In the standard version Rider 970 HST is fitted with
a Bioclip unit which cuts up the grass finely by
means of cutting it several times before it is returned to the lawn as fertiliser. Rider 970 is also
available with a cutting unit which has rear or side
ejection.
The diagram shows a Rider 970 with Bioclip unit.
RIDER 850RIDER 850RIDER 850
Lift lever for cutting unit
The lift lever is used to set the cutting unit in transport or cutting position.
If the lever is pulled back the unit will lift up and the
blades stop rotating (transport position).
If the lock button is pressed and the lever is moved
forward the unit will lower down and the blades
begin rotating (cutting position).
The lever can also be used to temporarily regulate
the cutting height, e.g. for a small mound in the
lawn.
