• Look out for the ejector and do not direct it towards anyone.

• Stop the engine and prevent it from starting before you clean the cutting unit.

• Remember that the driver is responsible for dangers or accidents.

• Never carry passengers. The machine is only intended to be used by one person.

• Always look downwards and backwards before and while reversing. Keep watch for both large and small obstacles.

• Slow before cornering.

• Switch off the blades when you are not mowing.

• Take care when rounding a ﬁxed object, so that the blades do not hit it. Never run the machine over foreign objects.

WARNING! The ignition system of this machine produces an electromagnetic ﬁeld

during operation. This ﬁeld may under some circumstances interfere with pacemakers. To reduce the risk of serious or fatal injury, we recommend persons with pacemakers to consult their physician and the pacemaker manufacturer before operating this machine.

• Learn how to use the machine and its controls safely and learn to how to stop quickly. Also learn to recognize the safety decals.

• Only allow the machine to be used by adults who are familiar with its use.

• Make sure nobody else is in the vicinity of the machine when you start the engine, engage the drive or drive off.

• Clear the area of objects such as stones, toys, wires, etc. that may become caught in the blades and be thrown out.

WARNING! This machine can sever hands and feet as well as throw objects. Failure to

observe the safety instructions can result in serious injuries.

WARNING! Engine exhaust, some of its constituents and certain vehicle

components contain or emit chemicals considered to cause cancer, birth defects or other reproductive impairment. The engine emits carbon monoxide, which is a colourless, poisonous gas. Do not use the machine in enclosed spaces.

• Only use the machine in daylight or in other well-lit conditions. Keep the machine at a safe distance from holes or other irregularities in the ground. Pay attention to other possible risks.

• Never use the machine if you are tired, if you have consumed alcohol, or if you are taking other drugs or medication that can affect your vision, judgement or coordination.

• Stop the engine and prevent the engine from being started until you have cleaned the outlet channel.

8 – English

Page 9

SAFETY INSTRUCTIONS

• Never allow children or other persons not trained in the use of the machine to use or service it. Local laws may regulate the age of the user.

WARNING! You must use approved personal protective equipment whenever you use the

machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.

• Use hearing protection to minimise the risk of hearing impairment.

This is what you do

• Remove obstacles such as stones, branches, etc.

• Mow upwards and downwards, not sideways.

• Do not use the machine on ground that slopes more than 10°.

• Avoid starting or stopping on a slope. If the tyres start to slip, stop the blades and drive slowly down the slope.

• Always drive smoothly and slowly on slopes.

• Do not make any sudden changes in speed or direction.

• Avoid unnecessary turns on slopes, if necessary, turn slowly and gradually downwards if possible. Drive slowly. Do not turn the wheel sharply.

• Watch out for and avoid driving over furrows, holes and bumps. It is easier for the machine to overturn on uneven ground. Tall grass can hide obstacles.

• Never wear loose ﬁtting clothes that can catch in moving parts.

• Never use the machine when barefoot. Always wear protective shoes or protective boots, preferably with steel toes.

• Make sure that you have ﬁrst aid equipment close at hand when using the machine.

Driving on slopes

Driving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it.

• Take extra care if any attachments are ﬁtted that can change the stability of the machine.

• Do not mow too close to edges, ditches or banks. The machine can suddenly overturn if one wheel comes over the edge of a steep slope or a ditch, or if an edge gives way.

• Do not mow wet grass. It is slippery, and tyres can lose their grip so that the machine skids.

• Do not try to stabilize the machine by putting your foot on the ground.

• When cleaning the chassis, the machine may never be driven near verges or ditches.

IMPORTANT INFORMATION

Do not drive down slopes with the unit raised.

English – 9

Page 10

SAFETY INSTRUCTIONS

• Follow the manufacturer’s recommendations regarding wheel weights or counterbalance weights to increase machine stability.

IMPORTANT INFORMATION

Wheel weights ﬁtted on the rear wheels are recommended when driving on slopes for safer steering and improved manoeuvrability. Consult your dealer concerning the use of wheel weights if you are unsure. Wheel weights can not be used on AWD-machines. Use counterweights.

Children

• Serious accidents may occur if you fail to be on your guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing. Never assume that children will remain where you last saw them.

• Keep children away from the area to be mowed and under close supervision by another adult.

• Keep an eye out and shut off the machine if children enter the work area.

• Before and during reversing procedures, look behind you and down for small children.

• Never allow children to ride along. They can fall off and seriously injure themselves or be in the way for safe manoeuvring of the machine.

• Never allow children to operate the machine.

• Petrol and petrol fumes are poisonous and extremely ﬂammable. Be especially careful when handling petrol, as carelessness can result in personal injury or ﬁre.

• Only store fuel in containers approved for the purpose.

• Never remove the fuel cap and ﬁll the petrol tank while the engine is running.

• Allow the engine to cool before refuelling. Do not smoke. Do not ﬁll petrol in the vicinity of sparks or naked ﬂames.

• Handle oil, oil ﬁlters, fuel and the battery carefully, of environmental considerations. Follow the local recycling requirements.

• Electrical shocks can cause injuries. Do not touch cables when the engine is running. Do not test the ignition system with your ﬁngers.

WARNING! The engine and the exhaust system become very hot during operation.

Risk of burn injuries if touched.

• If leaks arise in the fuel system, the engine must not be started until the problem has been resolved.

• Store the machine and fuel in such a way that there is no risk that leaking fuel or fumes can cause any damage.

• Check the fuel level before each use and leave space for the fuel to expand, because the heat from the engine and the sun may otherwise cause the fuel to expand and overﬂow.

• Avoid overﬁlling. If you spill petrol on the machine, wipe up the spill and wait until it has evaporated before starting the engine. If you spill on your clothing, change your clothing.

• Allow the machine to cool before performing any actions in the engine compartment.

• Be particularly careful near corners, bushes, trees or other objects that block your view.

Maintenance

• Stop the engine. Prevent starting by removing the ignition cable from the spark plug or remove the ignition key before making any adjustments or carrying out maintenance.

• Never ﬁll the fuel tank indoors.

WARNING! The battery contains lead and lead pollutants, chemicals that are

considered to cause cancer, birth defects or other reproductive impairment. Wash your hands after touching the battery.

• Be especially careful when handling battery acid. Acid on the skin can cause serious corrosive injuries. In the event of spillage on the skin wash immediately with water.

• Acid in the eyes can cause blindness, contact a doctor immediately.

• Take care with battery maintenance. Explosive gases form in the battery. Never perform maintenance on the battery while smoking or in the vicinity of open ﬂames or sparks. This can cause the battery to explode and cause serious injuries.

10 – English

Page 11

SAFETY INSTRUCTIONS

• Make sure all nuts and bolts are tightened correctly and that the equipment is in good condition.

• Do not modify safety equipment. Check regularly to be sure it works properly. The machine must not be driven if protective plates, protective covers, safety switches or other protective devices are not ﬁtted or are defective.

• Observe the risk of injury caused by moving or hot parts if the engine is started with the engine cover open or protective cowlings removed.

• Do not change the setting of governors and avoid running the engine at excessively high revs. If you run too fast, you risk damaging the machine components.

• Never use the machine indoors or in spaces lacking proper ventilation. Exhaust fumes contain carbon monoxide, an odourless, poisonous and highly dangerous gas.

Transport

IMPORTANT INFORMATION

The parking brake is not sufﬁcient to lock the machine during transport. Ensure you secure the machine ﬁrmly to the transporting vehicle.

• The machine is heavy and can cause serious crush injuries. Take extra care when loading it onto or off a vehicle or trailer.

• Use an approved trailer to transport the machine. Activate the parking brake, and secure the machine using approved fasteners, such as tension belts, chains or ropes when transporting.

• Check and observe local road trafﬁc regulations before transporting or driving the machine on roads.

• Stop and inspect the equipment if you run over or into anything. If necessary, make repairs before starting.

• Never make adjustments with the engine running.

• The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer.

• The blades are sharp and can cause cuts. Wrap the blades or wear protective gloves when handling them.

• Check regularly that the parking brake works. Adjust and maintain as required.

• The mulching unit should only be used where better quality mowing is required and in known areas.

PRESENTATION

Presentation

Congratulations on your choice of an excellent quality product that will give you great pleasure for many years. This operator’s manual describes PR 17, PR 17 AWD, PF 21 and PF 21 AWD. The machines are equipped with a four-stroke VTwin engine from Kawasaki.

The machines are equipped with power steering and hydraulic lifts. PR 17 AWD and PF 21 AWD also have all wheel drive.

The power transmission from the engine is handled by a hydrostatic gearbox, which allows variable variation of the speed by using the pedals. One pedal for driving forward and one for reverse.

Speed limiter

The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards, and pedal (2) to drive backwards.

WARNING! Make sure that branches do not obstruct the pedals when mowing under

bushes. Otherwise there is a risk you may lose control.

Counter

The chronometer shows how many hours the engine has been running.

Throttle control

The throttle control regulates the engine speed, and thereby also the rotation speed of the blades.

To increase or reduce the engine speed the control is moved forwards or backwards.

Avoid idling the engine for long periods, as there is a risk of carbon build-up on the spark plugs.

Choke control

The choke lever is used for cold starting and to give the engine a richer fuel mixture.

For cold starting the lever is moved backwards to its end position.

Any time when the engine is not running but the ignition is switched on is not registered. The last digit shows tenths of an hour (6 minutes).

Parking brake

The parking brake is applied as follows:

1 Press down the parking brake pedal (1).

2 Press in the lock button (2) on the steering column.

3 Release the parking brake pedal while keeping the button

pressed in.

The parking brake lock disengages automatically when the brake pedal is pressed.

Page 14

PRESENTATION

Cutting unit

PR 17 and PR 17 AWD can be equipped with three different cutting units. CombiTurf 94, CombiTurf 103 and CombiTurf 112

PF 21 and PF 21 AWD can be equipped with two different cutting units. CombiTurf 112 and CombiTurf 122

The Combi-unit, equipped with a BioClip-plug, ﬁnely chops the cuttings to fertiliser. Without the BioClip-plug the unit works in the same way as a rear ejection unit. The rear ejector ejects the clippings behind the unit without ﬁnely chopping them.

Lever for hydraulic lift of attachments

The lifting lever is used to put the cutting unit in either the transport or mowing position when hydraulic pressure is available.

When the lever is moved to the transport position, the blade brake is automatically activated so that the blades stop within about 5 seconds.

Lifting the Cutting Unit (Transport Position)

Pull the lever backwards to engage the transport position. The cutting unit will lift up and the blades stop rotating.

Lowering the Unit (Mowing Position)

If the cutting unit is secured in the transport position using the mechanical lifting lever, move the mechanical lifting lever to the cutting position.

Move the hydraulic lifting lever forwards to engage the cutting position. The unit is lowered and the blades begin to rotate.

In order to ensure that the hydraulic cylinder is in the outer position, hold the lever in the forward position for a half to one second.

Mechanical Lifting Lever for Cutting Unit

The lever is used as a backup lever to put the cutting unit in either the transport or mowing position when hydraulic pressure is unavailable. It can also be used to mechanically secure the cutting unit in the transport position.

The lever must be used when starting the engine, if the engine stopped with the unit in the mowing position, in order to raise the unit so that the start lock circuit is disengaged.

When the lever is moved to the transport position, the blade brake is automatically activated so that the blades stop within about 5 seconds.

Transport position

If the lever is pulled backwards the unit is raised and the blades automatically stop rotating (transport position).

Secure the cutting unit if necessary using the mechanical lifting lever.

14 – English

Page 15

PRESENTATION

Mowing Position

If the lock button is pressed in and the lever is moved forwards the unit will be lowered and the blades will automatically start to rotate (mowing position).

If this does not happen it is probably because the unit has been lifted with the hydraulic lifting lever. Lower the unit to the mowing position with the lever for the hydraulic lift.

Cutting height adjustment lever

The cutting height can be adjusted to 7 different positions with the cutting height lever.

The seat springing can be adjusted by moving the rubber stops in their mountings on the underside of the seat. Place both stops in the front, middle or rear.

Fuelling

The engine runs on unleaded petrol with a minimum octane rating of 87 (not mixed with oil). We recommend the use of biodegradable alkylate petrol. (max. methanol 5%, max. ethanol 10%, max. MTBE 15%)

Do not ﬁll the tank completely, leave an expansion area of at least 2.5 cm (1“).

It is important that the air pressure in both front wheels is equal, 60 kPa/8.5 PSI, to produce an even cutting height.

Seat

The seat has a jointed attachment on the front edge and can be tipped forward.

The seat can also be adjusted lengthways.

To adjust move the lever under the front edge of the seat to the left, so that the seat can be moved forward or backwards to the required position.

WARNING! Petrol is highly inﬂammable. Exercise care and refuel outdoors (see

safety instructions).

IMPORTANT!

Do not use the fuel tank as a support area.

Driving

Cutting tips

WARNING! Clear the lawn from stones and other objects which can be thrown out by

the blades.

• Localise and mark stones and other ﬁxed objects to avoid collision.

• Start with a high cutting height and reduce down until the required mowing results are obtained.

• The mowing 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 without noticeably depreciating the mowing result.

• 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. The cutting unit should then be put in the service position.

• When the BioClip function is used, it is very important that the mowing interval is not too long.

WARNING! Do not use the machine on ground that slopes more than 10

slopes upwards and downwards, never across. Avoid sudden changes in direction.

°°°°.... Mow

Before starting

• Read the safety instructions and information concerning the placement of controls and functions before starting.

• Perform daily maintenance before starting as set out in the Maintenance schedule.

IMPORTANT INFORMATION

The air intake grille in the engine cover behind the driver’s seat must not be blocked by, for example, clothing, leaves, grass or dirt. Impaired cooling of the engine. Risk of major engine damage.

Start the engine

1 Make sure that the clutch control is depressed. PR 17

AWD and PF 21 AWD have one control for the front axle and one control for the rear axle.

Grease both ends of the cables and move the controls to end stop positions when lubricating.

Re-attach the rubber covers on the cables after lubrication.

Cables with sheaths will jam if they are not lubricated regularly. A jammed cable may cause malfunction, such as the parking braking being applied. If a cable binds, remove the cable and hang it vertically. Lubricate it with thin engine oil until the oil begins to escape from the bottom.

A tip: Fill a small plastic bag with oil and tape it so that it seals against the casing and allow the cable to hang vertically from the bag overnight. If you do not succeed in lubricating the cable, it must be replaced.

Checking the engine’s oil level.

Check the oil level in the engine when the Rider stands horizontal with the engine switched off.

Open the engine cover.

Loosen the dipstick, pull it up and wipe it off.

Now insert the dipstick again, without tightening it.

Pull the dipstick out again and read the oil level.

The oil level should be between the markings on the dipstick. If the level is approaching the ADD mark, top up the oil to the FULL mark on the dipstick.

• Lubricate the joints, catches, and bearings for the cutting unit’s control levers with an oilcan.

Replace the lever housing’s side cover.

Lubricating the belt adjuster

Lubricate using a grease gun, 1 nipple from the right-hand side under the engine’s lower belt pulley, until grease is forced out.

The oil is topped up through the hole the dipstick sits in. Fill the oil slowly.

Tighten the dipstick correctly before starting the engine. Start and run the engine at idling speed for approx. 30 seconds. Turn off the engine. Wait 30 seconds and check the oil level. If necessary ﬁll so that the oil comes up to the FULL mark on the dipstick.

The following oil classes are recommended:

• API Service Class: SF, SG, SH and SJ

Choose an oil with viscosity according to the temperature ranges in the ﬁgure:

Do not mix different types of oil.

Caution when using oils such as 5W-20, 10W-30 and 10W-40 the engine’s oil consumption increases. If these oils must be used, check the oil level frequently.

Use only good quality molybdenum disulphide grease.

Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality.

Hydraulic System

PF 21 AWD

PR 17, PR 17 AWD, PF 21

Keep the hydraulic system clean. Bear in mind that:

• Thoroughly clean before the top-up cap is opened or any connector loosened.

• Use clean containers when topping up the oil.

• Only use pure oil that has been stored in a sealed container.

• Do not reuse drained oil.

• Change the oil and ﬁlter according to the intervals speciﬁed in Maintenance Schedule.

In order for a hydraulic system to function without problem, it must be free from foreign objects. When used, the system produces particles, which can cause both wear and abnormal function. In order to remove these particles, the system contains ﬁlters. The ﬁlters are sized so as to capture the produced particles, but if contaminants are introduced from outside the system, the ﬁlters can quickly become clogged and fail to function as intended. If there are contaminants in the system, further contamination will be produced in a self-propagating cycle. The result will be operating disruptions and much work to clean the system.

Storage

Winter storage

At the end of the season, or if the machine is going to stand idle for more than 30 days, it should immediately be made ready for storage. 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.

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, drying cabinets, etc. Exercise caution when handling fuel. It is highly inﬂammable, and careless use can cause serious injury and damage to property. 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.

Guard

There is a cover to protect your machine during storage or transport. Contact your dealer for a demonstration

Service

Low season is the most suitable time to perform a service or overhaul of the machine in order to ensure high function safety during high season.

When ordering spare parts state your machine’s purchase year, model, type, and serial number.

Always use genuine parts.

Annual inspection or tuning by an authorised service workshop is a good way of getting the best out of your machine the next season.

To prepare the machine 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 engine 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 plugs and pour about a tablespoon of engine

oil into each cylinder. Pull round the engine to distribute the oil and screw the plugs back on.

6 Grease all grease nipples, joints and axles.

7 Remove the battery. Clean it, charge it, and store it in a

cool place.

8 Store the machine in a clean and dry place and cover it

over for extra protection.
