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.

not

do the following:

• Avoid unnecessary turns on slopes, and if

turning is necessary turn slowly and gradually, downwards if possible.

RIDER 850RIDER 850RIDER 850

Be extra careful when driving on slopes.

Cut slopes upwards and downwards, not sideways.

6 – 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.

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.

RIDER 850RIDER 850RIDER 850

Never allow children to drive the machine.

RIDER 850RIDER 850RIDER 850

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.

RIDER 970RIDER 970RIDER 970

Never fill up with fuel indoors.

English – 7

• 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 attach-

ment bolts for the blade units are properly tightened and that the equipment is in good order.

SAFETY INSTRUCTIONS

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 run-

ning.

• 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.
