MACHINERY/EQUIPMENT CONNECTED TO HYDRAULICS
Be careful when you connect your machine or equipment to a hydraulic hose.
DANGER!
Pressurised oil and fuel leaks can penetrate skin and cause serious injuries. Do not use your
hands to locate leaks. Use a piece of paper or cardboard to search for leaks.
• Warning for high pressure, risk of penetration injury.
• Before repairs or maintenance are carried out, the system must be relieved of any
remaining pressure.
• Turn o the tractor and move the hydraulic levers back and forth to release any pressure
that may still be in the oil hoses and pipes before starting any work on them or the
hydraulic cylinders.
• Clean the lter in the suction pipe after 10 hours' work.
• Immediately replace hydraulic hoses if cracks or wear are detected.
• Do not adjust the valve settings. Incorrect adjustment can result in damage to the
machine and/or injury.
• The hydraulic system must only be operated using hydraulic oil intended for the purpose.
Check the oil level before you start the machine!
• When commissioning a new machine, it is recommended that the hydraulic oil is changed
after the rst 10 hours of operation, in order to remove any dirt or metal chips which may
have got into the hydraulic system.
NOTE: The oil becomes hot when it ows through the hydraulic system. Check the oil temperature at regular
intervals in order to avoid overheating. Stop the machine if the oil becomes overheated and allow the oil to
cool down.
Table of Contents
CHEMICALS
To maximise the service life of a product/equipment, maintenance - and not least preventive
maintenance - is important, and this is largely what greases and oils do. Carefully read the
operating manuals for your new products or equipment to ensure correct maintenance and
service life and that the warranty remains valid!
Lubricating greases
First aid measures.
Inhalation - In the event of unintended inhalation of fumes, move the injured person into
fresh air.
Skin contact - Wash with soap and water. Contact a doctor in the event of eczema or skin
complaints.
Eye contact - Remove contact lenses, if any, before rinsing. Rinse thoroughly with large
amounts of water, including under the eyelids. Contact a doctor if discomfort remains.
Ingestion - DO NOT induce vomiting. Drink water in small quantities. In the event of ingestion
or discomfort, contact the poison information service or a doctor.
Hand protection - Wear protective gloves.
Eye protection - Avoid contact with eyes. Wear approved protective goggles.
Body protection - Suitable protective clothing.
Respiratory protection - No protection is necessary during normal handling.
Greases should be stored well-sealed in a cool place in a well-ventilated area. Storage
temperature must not exceed 45°C. Keep away from heat, ames and sparks. The function and
strength of materials such as steel, plastic, oils, grease etc. deteriorates considerably at very
low temperatures (-20 to -30°C).
Degreasing
To ensure the best lubricating eect, you need to clean parts of the product or equipment
from time to time. We recommend degreasing to achieve thorough cleaning and to remove
all residues of old lubricant, which may contain destructive particles.
The degreasing agent we supply at Kellfri is OKQ8, in a 20-litre can.
Keep chemicals out of the reach of children and animals.

RISKS AND HAZARDS ASSOCIATED WITH THE USE OF GARDEN MACHINERY
Risk of crushing
Observers can be injured when the machine is lowered in the cutting position. Pasture toppers have
crushing points around the hinge areas and between the three-point attachment and the main body.
Respect the risk zone of 15 m!
Rotating blades
WARNING! Any person can risk injury by putting their hands or feet under the machine when it is lifted
from the ground and the blades are still rotating. Nobody is allowed in the vicinity during operation or
when the machine is running.
Risk of crushing
This risk is common in mechanical transmission devices such as belt drives, bevel gears and rollers.
Ensure that all guards are correctly tted.
Rotating blades
Risk when disengaging machine
The heavier a rotating part is, the longer it will continue to rotate after the wheel drive has been
disconnected. This property is called free-wheeling. Rotating blades and other components such as drive
shafts etc. will continue to spin round after the wheel drive has been disconnected. Injuries occur:
• When the operator disconnects the equipment and attempts to clean or adjust the machine before
the components have stopped rotating.
• When the shear bolt in the protective device in the power outlet disintegrates and the rotors continue
to spin while the power outlet has stopped. The operator's awareness is of key importance for safety
around rotating parts. Never raise the machine while the blades are still rotating!
Risk of ejected objects
Machines that cut grass eject material during operation. Foreign objects such as stones, sticks and other
debris can nd their way under the machine and be ejected at great speed. Metal guards at the sides and
front prevent these objects being ejected, but this is no guarantee that they will always capture everything.
Observers or animals standing in the way of an ejected object can suer serious injury.
Never operate the machine when there are observers nearby. Respect the equipment's
risk zone of 15-25 m!
Noise
Note that the machine is intended for outdoor use and that the operator's position is the driver's seat of
the tractor. It is advisable to read the directions given in the tractor manual and maintenance instructions.
The sound pressure level during operation exceeds 70 dB. Hearing protection must therefore be worn
during operation.
Accidents involving slipping and falling are often a result of:
• Slippery surface
• Uneven steps and work platforms.
The risk of slips and falls can be reduced considerably by exercising good judgement.
All unprotected rotating machine parts increase the risk of accidents. Accidents usually occur when
loose-tting clothing or long hair is caught and wrapped around rotating parts, such as PTO shafts or
drive shafts on the machine. Ensure that all guards are correctly tted.
Table of Contents
Drive safely on public roads
• Always follow trac safety rules on public roads, and following the regulations applying
to driving a tractor with towed equipment on a public road.
• Check that reectors, warning signals and/or warning ags indicating protruding
equipment are tted to the machine or tractor. These indicators must be correctly
mounted, and must be visible and easy for drivers of other vehicles to see.
• Observers must not lean against or climb onto the machine during transport or during
work. NEVER allow anyone to travel on the machine!
• The maximum transportation speed must not exceed 20 km/h
• Brake regulations: If the gross weight of the trailer exceeds the gross weight of the towing
vehicle, the trailer must be equipped with a brake. For further information, contact the
trac authorities.
• IMPORTANT! Mark protruding equipment clearly with additional lights or suitable
reectors. It is important that the equipment is visible! If you are driving on a public road,
any load or equipment protruding in front of or behind the tractor must be marked. In
darkness, at dusk or dawn or in weather with poor visibility, the load must be marked
with a white reector and lantern at the front and a red reector and lantern at the rear.
In daylight you can mark the load with a ag or a piece of fabric in colours which are easy
to notice, such as red and yellow.
• Think about front-loaded equipment. As well as marking front-loaded equipment clearly,
you can also try to make front-loaded equipment such as a bucket, bale spike or pallet
forks less aggressive if another driver should collide with it.
• Before going out onto public roads, it is also always advisable to look over your vehicle
and check that the brake system on the following vehicle is working, and that your tow
bar eyes are not too worn. A worn-out towing eye can break if subjected to a heavy loaf,
and you can lose your cart.
• It is also advisable to check that the SMV sign is clearly visible from behind. If it is obscured
by any equipment or load behind, you must hang an additional one at the rear of the
vehicle train.

BEFORE USING A FLAIL MOWER
Read the towing vehicle's instruction book before connecting equipment.
• Check the cog belt's tension, and adjust when necessary.
• Check that the ails are not defective, and replace if necessary,
• Ensure that all nuts, bolts and installations are securely mounted, that all packing/
transport material such as tape, steel bands, rope etc. has been removed.
• Check that the oil level in the engine is correct and that there is petrol in the tank.
• Check that the tyre pressure is correct. See information on tyre pages. Do not exceed the
maximum pressure!
• Ensure before use that all guards are in place and are not able to come loose.
• Connect the equipment to the ATV’s tow bar ball coupling.
• Press grease into all grease nipples.
ADJUSTMENT OF TOW BAR
The height of the tow bar attachment on the towing vehicle may vary. For adjustment of the
settings, there is a screw rod under the tow bar. It should be lengthened or shortened so that
the ail mower is horizontal on level ground. (This gives a more eective cutting performance.)
Screw/turn the rod: lengthen the rod to raise the tow bar or shorten to lower it (illustration 1)
IMPORTANT! TIGHTEN BOLTS BEFORE STARTING OPERATION AND AFTER THE FIRST
DAY OF OPERATION!

STARTING THE ENGINE
1. Read and understand the engine's operating manual before using the machine.
2. Observe all safety regulations: Keep hands and feet away from blades and other moving
parts.
3. Ensure that bystanders are at a safe distance from the machine.
4. Ensure that there is space between the blades and the ground/grass.
5. Select an area free of loose objects that can be ejected.
6. Turn the choke to the on position and set at idling.
7. Place one foot on top of the machine so that you have a rm grip and a good balance.
Pull the starter cord and let it return slowly back to the engine.
8. Allow a few minutes for the engine to warm up while idling. Set the throttle at
the factory setting for operation in order for the engine to have a normal working
speed of max. 3600 rpm.
Warning!
Altering the accelerator setting to increase rpm above the recommendations given
can invalidate the warranty. Cutting performance will decline, fuel consumption will
increase and major vibrations may arise, leading to danger for persons and damage
to equipment.
DRIVING AND SPEED
The amount of grass to be cut determines the forward speed; low speed usually produces the
best results. Ensure that you follow the sequence below. Normal speed: 1 km/h for heavy
work, 10 km/h for light work. Start with the lowest possible speed; ensure that the ail mower
is working eectively with the engine at maximum rpm without straining. (If this is not possible
because of very tough cutting conditions, raise the cutting level and cut the same area twice,
the second time with a lower cutting level. Allow at least 24 hours between rst and second
cutting to allow the grass to dry out.)
Increase the forward speed until the engine starts to labour, then slow down immediately and
maintain a speed where the engine runs easily. It is important to always listen to the engine
to be sure that the engine and ail mower are working eectively - slow down or stop if the
engine starts to labour.
Warning!
When changing from normal to heavier cutting, it is usual for the engine to start labouring
with a drop in rpm. SLOW DOWN IMMEDIATELY so that the engine returns to normal rpm
and speed. Follow the instructions above in“Normal speed”. Expected speed is much lower
when the machine is working hard.

ADJUSTMENT OF CUTTING HEIGHT
The cutting height can be adjusted at three (3) places: the tow bar, the support roller and the
wheels.
To raise or lower the cutting unit, adjust the following: raise or lower the wheels, raise or lower
the tow bar and roller or the tow bar and wheels.
Adjust the height as follows:
STEP 1 Wheels = Raise and lower the wheels by turning the levers. Check that both wheels are
at the same height.
Adjustment of wheel height.
When in operating mode, the
wheels must be adjusted. Turn the
height adjustment levers to raise
and lower the wheels.
STEP 2 Combination of tow bar and support roller = Lengthen the tow bar (screw/turn the
turnbuckle) to raise the tow bar or shorten it to lower it.
Raise the roller by loosening bolt 'B', loosen and remove bolt 'A'. (Repeat this on both sides of
the roller.) Then select a dierent hole and replace bolt 'A'. Tighten bolts 'A' and 'B' (illustration)

STEP 3 Combining tow bar and wheels: Raise or lower the tow bar exactly as described in the
previous step. (Turn the turnbuckle in or out to shorten or lengthen the tow bar.)
Raise the wheels by turning the levers on both sides of the machine. Check that both wheels
are at the same height.
Adjustment of wheel height.
When in operating mode, the wheels must
be adjusted. Turn the height adjustment
levers to raise and lower the wheels.
The skids should not drop and touch the ground. The skids are to support the machine over
obstacles such as large stones or mounds of earth. If the skids touch the ground they will
cause ground damage and deep grooves, and the ails will hit the ground.
Important!
TRANSPORT MODE
When the ail mower is to be moved from one workplace to another, it is advisable to raise
the unit to the highest position, using a screw jack. (See section on cutting height.) The engine
must be turned o and the blades must have stopped before changing to transport mode.
Remove any loose material such as grass, etc. from the mower before leaving the eld. Never
move from one place to another with the engine running.
Please note that the ail mower is not legally authorised to use public roads. It should
not therefore be used on public roads. Maximum driving speed is 30 km/h.
LEVER HEIGHT ADJUSTMENT
IMPORTANT! Operating speed should be adjusted to suit the prevailing cutting
conditions. If the engine labours, the speed should be reduced. Be careful when
operating on uneven ground.
Lock. Locks the lever.

SUPPORT ROLLER AND SIDE SKIDS
The main purpose of the support roller and the side skids is to prevent damage. If one of the
wheels runs down in one direction, or if there is uneven ground between the wheels, the roller
takes the weight of the mower and thus prevents the blades from touching the ground. The
support roller combined with the side skids gives the rotor good protection. The support roller
has the additional advantage of allowing grass edge cutting, as the roller enables the wheels
to hang outside the edge. The factory-set position of the roller and side skids is suitable for
most situations. But if the ail mower is often used in slightly tougher terrain, the roller and
side skids should be lowered to give increased ground clearance for the rotor and blades.
When the ail mower is used for 'trimming', the roller can be raised by using the various holes
to give the desired cutting height, and the wheels can be raised o the ground.
TO ADJUST THE SUPPORT ROLLER:
Loosen level bolt 'B', loosen and remove bolt 'A'. (Repeat this on both sides of the roller.)
Then select a dierent hole and replace bolt 'A'.
Tighten bolts 'A' and 'B'.

Basic adjustment of skids:
Adjust the skids as protection for the ails, allowing the skids to be about 2 cm closer to the
ground than the skids in their lowest position.
TYRE PRESSURE
Do NOT exceed the recommended tyre pressure. See info on sides of tyres for exact value.

INSPECTION OF ROTOR BEARINGS
Turn the rotor axle by hand and feel for any unevenness in the bearings. Also try to move the
axle from side to side to discover any looseness. If you discover any unevenness or looseness,
remove the axle casings to inspect the bearings more closely.
INSPECTION OF OIL LEVEL IN ENGINE
With your mower in a horizontal position, open the oil relling tap
and check that the oil level is up to the brim - see illustration.

INSPECTION OF COG BELT
A rst inspection and retensioning must be performed after one hour's operation, to ensure
that the cog belt is correctly tensioned. Check the cog belt regularly and tighten when
necessary. Belt tensioning: the belt should move 20 mm (10 mm on each side) under pressure.
ADJUSTMENT BOLT
INSPECTION OF WHEEL BEARINGS
First, ensure that all wheel nuts and bolts are suciently tightened. Raise one side of the ail
mower so that one of the wheels is exactly above the ground. Turn the wheel by hand and
check the wheel's position. To check the bearings, try to move the wheel from left to right and
feel for any looseness. Replace bad bearings.
GREASING THE 50 MM TOW BAR COUPLING
Check the coupling for signs of damage or wear, swivel the coupling 360 degrees and check
that the bushings are not worn. Replace damaged and/or worn parts.
Grease the ball coupling regularly.
BLADE MAINTENANCE
The ail mower is equipped with blades manufactured for a long service life. If a blade loosens
or breaks, it is important to replace it immediately. If this is not done, imbalance may occur,
which could have very serious consequences. When replacing the blade, the blade on the
opposite side of the rotor must also be inspected for damage and wear. If it is partly or wholly
worn, it must be replaced to maintain the correct weight balance. When the rst cutting edge
begins to become blunt, the entire set should be turned or replaced. Use of blunt blades
reduces cutting performance and increases fuel consumption.
Blades must be replaced as follows:
A) Ensure that the engine is switched o and the blades are not rotating. Turn o the fuel tap
and allow the engine to cool down for ve minutes. Remove the spark plug to ensure that the
engine cannot start.
B) Raise the mower to its maximum cutting height.
Carefully raise the tow bar to a slightly inclined position so that the height adjustment bar can
take some weight.
D) Loosen and remove the bolts.
E) Replace the blades. (Take note of the direction of rotation.)
F) Screw the bolts tightly back in place and check that the blades move on the axle.
NOTE: When lubricating wheel bearings: take care not to pump
in too much lubricant. Excess lubricant gets into the drive belts,
causing them to slip and burn.
Remove the protective fairing for a full inspection of the belts
when lubricating, and wipe o excess lubricant if necessary. Lu-
bricate regularly.
