1. Safety rules for USA
These instructions are for your safety. Read them carefully.

Safe operation practices for ride-on mowers
IMPORTANT!
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to
observe the following safety instructions could result in serious injury or death.

General operation

1. Read, understand and follow all instructions in
the manual and on the machine before
starting.
2. Only allow responsible adults, who are familiar
with the instructions, to operate the machine.
3. Clear the area of objects such as rocks, toys,
wire, etc., which could be picked up and
thrown by the blade.
4. Be sure the area is clear of other people
before mowing. Stop the machine if anyone
enters the area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely
necessary. Always look down and behind
before and while backing.
7. Be aware of the mower discharge direction
and do not point it at anyone. Do not operate
the mower without either the entire grass
catcher or the guard in place.
8. Slow down before turning.
9. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine and remove keys before dismounting.
10. Turn off blades when not mowing.
11. Stop engine before removing grass catcher or
unclogging chute.
12. Mow only in daylight or good artificial light.
13. Do not operate the machine while under the
influence of alcohol or drugs.
14. Watch for traffic when operating near or
crossing roadways.
15. Use extra care when loading or unloading the
machine into a trailer or truck.

II.

Slope operation

Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra caution. If
you cannot back up the slope or if you feel uneasy
on it, do not mow it.
DO
Mow up and down slopes, not across.
Remove obstacles such as rocks, tree limbs,
etc.
Watch for holes, ruts or bumps. Uneven
terrain could overturn the machine. Tall grass
can hide obstacles.
2 – English

Use slow speed. Choose a low gear so that
you will not have to stop or shift while on the
slope.
Follow the manufacturer’s recommendations
for wheel weights or counterweights to improve
stability.
Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
Keep all movement on the slopes slow and
gradual. Do not make sudden changes in
speed or direction.
Avoid starting or stopping on a slope. If tires
lose traction, disengage the blades and
proceed slowly straight down the slope.
DO NOT
Do not turn on slopes unless necessary and
then, turn slowly and gradually downhill, if
possible.
Do not mow near drop-offs, ditches or
embandments. The mower could suddenly turn
over if a wheel is over the edge of a cliff or
ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction
could cause sliding.
Do not try to stabilize the machine by putting
your foot on the ground.
Do not use grass catcher on steep slopes.

III. Children
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often
attracted to the machine and the mowing activity.
Never assume that children will remain where you
last saw them.
1. Keep children out of the mowing area and
under the watchful care of another responsible
adult.
2. Be alert and turn machine off if children enter
the area.
3. Before and when backing, look behind and
down for small children.
4. Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.
5. Never allow children to operate the machine.
6. Use extra care when approaching blind
corners, shrubs, trees or other objects that may
obscure vision.

1. Safety rules for USA
IV. Service
1. Use extra care in handling gasoline and other
fuels. They are flammable and vapours are
explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel with the
engine running. Allow engine to cool before
refuelling. Do not smoke.
c) Never refuel the machine indoors.
d) Never store the machine or fuel container
inside where there is an open flame, such as
in a water heater.
2. Never run a machine inside a closed area.
3. Keep nuts and bolts, especially blade
attachment bolts, tight and keep equipment in
good condition.
4. Never tamper with safety devices. Check their
proper operation regularly.
5. Keep machine free of grass, leaves or other
debris build-up. Clean up oil or fuel spillage.
Allow machine to cool before storing.
6. Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
7. Never make adjustments or repairs with the
engine running.
8. Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown.
Frequently check components and replace with
manufacturer’s recommended parts, when
necessary.
9. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
10. Check brake operation frequently. Adjust and
service as required.

Travel and transport on public roads
Check the relevant road traffic regulations before
driving the machine on a public road. If transporting
the machine on another vehicle always use
approved securing devices and make sure that the
machine is securely held.
Towing
If your machine has a hydrostatic transmission you
should only tow it very short distances at low speed
if absolutely necessary, otherwise the transmission
may be damaged.
Intended use
This machine is designed solely for cutting grass
on conventional lawns and other cleared and
leveled ground without obstacles, as rocks, stumps
etc., and, in conjunction with accessories supplied
by the manufacturer even for other special tasks
for which instructions are delivered with the
accessory. Use in any other way is considered as
contrary to the intended use. Compliance with and
strict adherence to the conditions of operation,
service and repair as specified by the manufacturer
also constitute essential elements of the intended
use.
This machine should be operated, serviced and
repaired only by persons who are familiar with its
particular characteristics and who are acquainted
with the relevant safety procedures.
Accident prevention regulations, all other generally
recognised regulations on safety and occupational
medicine, and all road traffic regulations must be
observed at all times.
Any arbitrary modifications carried out to this
machine may relieve the manufacturer of liability
for any resulting damage or injury.

Safe operation practices for Ride-On Mowers
Before starting cutting operations, train different
driving operations on an open ground without
people nearby until you feel familiar with handling
the equipment. This is particularly important if you
have no or little prior experience of driving a
vehicle.
Data indicates that operators, age 60 years and
above, are involved in a large percentage of riding
mower-related injuries. These operators should
evaluate their ability to operate the riding mower
safely in order to protect themselves and others
from serious injury.
Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere
with safe machine operation.

Danger, keep hands and feet away

SAFETY INSTRUCTIONS
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.
Proceed as follows:
•

Remove obstacles such as stones, branches,
etc.

•

Mow upwards and downwards, not sideways.

•

Do not use the machine on ground that slopes
more than 15°.

•

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.

•

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.

•

Drive slowly. Do not turn the wheel sharply. The
machine engine-brakes better in low gear.

•

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 the
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 under the machine, it may never
be driven near verges or ditches.

•

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

10 – English

6003-004

Mow upwards and downwards on slopes, not sideways.

8010-054

Be especially careful when driving on slopes.

SAFETY INSTRUCTIONS
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

DRIVING
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.

6007-009H

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 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.

•

Wash down the underside of the cutting unit with
water after use. Do not use a high pressure jet.
Put the cutting unit in the service position while
doing this.

•

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.

Engine oil can be very hot if it is
drained off directly after the engine
is stopped. Therefore allow the
engine to cool down first.
1. Place a receptacle under the engine’s drain
plug, located on the left-hand side of the engine.

8009-465

2. Remove the dip stick and drain plug (A).
3. Let the oil run out into the receptacle.
4. Fit the drain plug and tighten.

IMPORTANT INFORMATION

5. Fill up with oil to the FULL mark on the dip stick.
The oil is filled in the same hole for the dip stick.
See ”Checking the engine’s oil level” above for
filling instructions. The engine holds 1.9 litres
(1.8 USqt) of oil.

Used engine oil is hazardous to health and
environment and must in accordance with
the law not be poured out on the ground
or in the nature, and must be handed in to
a workshop or other designated station for
treatment. Avoid skin contact, wash with
soap and water in the event of spillage.

6. Run the engine warm and then check that there
is no leakage from the drain plug.

LUBRICATION
Change of oil filter
Replace oil filter every 200 operating hours. Drain
oil first using the plug on the filter base. Remove
the old filter using an oil filter tool. Lightly coat
rubber gasket with new oil, then install filter by
turning it to the right until hand tight. Tighten the
filter an additional 1/2 turn. Check that the drain
plug is reinstalled before starting the engine.
Start engine and check for leakage.

8009-466

Check the transmission’s oil level
1. Remove the transmission cover. Loosen both
screws (one on each side) and lift off the transmission cover.

2. Check that there is oil in the transmission’s oil
tank. Fill if necessary with engine oil SAE 10W/
30 (class SF–CC).

Lubricating the belt adjuster
The belt adjuster should be lubricated regularly
using good quality molybdenum disulphide
grease*.
1 nipple from the right-hand side under the engine’s
lower belt pulley, until grease is forced out.
With daily use lubrication should be conducted
twice a week.

General lubrication

6008-240H

All joints and bearings are lubricated on
manufacture with molybdenum sulphide grease.
Re-grease with same type of grease*. Lubricate the
steering and control wires with engine oil.
The machine should be lubricated regularly, and
twice a week when used daily.
* Grease from well-known brand names (petrol
companies, etc.) usually maintains a good quality.
The most important property is that the grease
provides good protection against corrosion.

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.

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.

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 in the cylinder. Turn
over the engine so that the oil is evenly
distributed and then refit the spark plug.
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 for extra protection.

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

Service
When ordering spare parts, always 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.
