2 │WORK SAFETY AND HEALTH
Riding mowers model number AB107 under the brand name CHALLENGE are manufactured according to valid European safety
norms. The machine's manufacturer confirms this fact in the Statement of compliance, which is included at the end of this
user's manual ( 10).
If this machine is used properly and according to the user's manual, it is very safe.
In the event that work safety is not adhered to and all warnings in this manual are not respected, this riding mower may
cut off hands, legs or deflect objects and so may cause serious injury or death to persons, damage or destructions of the
machine or one of its parts or accessories.
2.1 |SAFETY INSTRUCTIONS
The person primarily responsible for their own safety and the safety of others during the operation of the riding mower is its user.
The manufacturer takes no responsibility for the injury of persons or damage to the machine and ecological damage resulting from
the machine not being used and operated in accordance with all safety instructions included in this user's manual.
2.1.1 GENERAL SAFETY INSTRUCTIONS
!This machine may only be driven by a person over 18 years of age that has read this user's manual. Never allow this machine to
be operated or serviced or maintained by persons that are not competent for the respective activity.
!The user of the machine is responsible for the safety of persons in the vicinity of the working area of the machine.
!It is not permitted to perform any technical modifications to the machine and its accessories without the manufacturer's written
consent. Unauthorised modifications may lead to hazardous work safety conditions and void the warranty.
!Adhere to all requirements relating to fire safety ( 2.4).
!Do not remove safety stickers or labels from the machine.
!Do not stay in the vicinity of the machine or under it, if it is lifted and is not sufficiently secured against falling or tipping over in
the lifted position.
!Always turn off the mowing deck and engine and take the key out of the ignition, when:
- you are cleaning the machine
- you are removing grass clippings accumulated in the mowing deck or side discharge cover
- you have driven over a foreign object and it is necessary to check whether the machine has been damaged or it is necessary
to remedy the damage
- the machine is vibrating with unusual force and it is necessary to identify the cause of the vibrations
- you are repairing the engine or other moving parts (also disconnect cables from the spark plugs)
2.1.2 CLOTHING AND PROTECTIVE AIDS OF THE DRIVER
!When operating the machine, always use appropriate work attire. Never wear loose clothing and short pants.
!When operating the machine, always wear firm, closed footwear, ideally with non-slip soles. Never operate the machine when
wearing sandals or barefoot.
!Usually the noise emitted during mowing does not exceed the acoustic pressure and acoustic power values specified in this
user's manual ( 1.4). In certain cases, however, it may under certain conditions and due to the condition of the terrain exceed
the specified noise levels for a short time. Therefore, the machine manufacturer recommends the use of hearing protection
when operating the machine because stressing the hearing organ with an excessive noise level or long term effects of noise
may lead to permanent hearing damage.
2.1.3 BEFORE USING THE MACHINE
!Do not use the riding mower if it is damaged or if any of its protective elements are missing. All covers and other protective
elements must always be in their place. Therefore, do not remove or put out of operation any of the machine's protective
elements. Regularly check that these elements are working correctly.
!Do not work with the machine after consuming alcohol, drugs or medication affecting your perception.
!Do not work with the machine if you suffer from dizziness, fainting or if you are weakened or distracted in any other way.
!Before putting the machine into operation, thoroughly learn about all the control elements and ensure that you can control them
in such a way that if necessary you can immediately stop or turn off the engine.
!Do not adjust the engine regulator or the engine speed limiter.
!Before you start working with the machine, remove from the surface of the area you will be mowing, all stones, pieces of wood,
wire, bones, fallen branches and other items, which could be deflected during the mowing process. Always use protective
gloves during this.
!Remedy all defects before further use. Before starting work, thoroughly check that the belts are tensioned, the blades are sharp
and that the area inside the mowing deck is clear.
!Before using the machine, visually check that the machine parts are not damaged or missing or visibly loosened.
!Prior to using the machine check that the brakes work and if necessary have them adjusted or repaired.

19
2.1.4 WHILE OPERATING THE MACHINE
!The machine must not be used for work on slopes that have an incline greater than 12° (21%).
!Transport of other passengers, animals or loads directly on the machine is forbidden. Transport of loads is only permitted on
trailers approved by the machine's manufacturer.
!Even when leaving the machine for a short time, always remove the key from the ignition.
!If you are driving the machine away from the work area where you are mowing, always disengage the mowing deck and lift it to
the transport position.
!Do not mow near piles of material, holes or banks. The riding mower may suddenly roll over if the wheel goes over the edge of
a hole, trench or an edge that may collapse.
!When working, avoid mole mounds, concrete supports, tree stumps, garden bed and footpath kerbs, which must not come into
contact with the blades and so cause damage to the mowing deck, the side discharge cover and the machine's mechanism.
!In the event of an impact into a rigid object, stop and turn off the mowing deck and engine and inspect the entire machine,
particularly the steering mechanism. If necessary perform repairs before starting up the engine again.
!Whenever possible avoid using the machine in wet grass. Reduced traction may lead to skidding.
!Avoid obstacles (e.g. sudden change in the incline of a slope, trenches, etc.) on which the machine could roll over.
!Do not attempt to maintain the stability of the machine by stepping on the ground.
!Only use the machine in daylight hours or with good artificial lighting.
!Lightning can cause serious injury or death. Do not use the machine when a storm is approaching and lightning flashes can be
seen or thunder can be heard, find safe shelter.
!Driving the machine on public roads is not permitted.
!Do not leave the engine running in closed areas. The exhaust fumes contain substances that are odourless but are fatally
poisonous.
!Do not put your hands or legs underneath the mowing deck cover or the side discharge cover. Never put any part of your body
near the rotating or moving parts of the machine. Do not attempt to use your hands or other temporary items to stop or slow
down moving cutting blades!
!Do not start the engine without an exhaust pipe.
!Always pay full attention to driving and other activities performed with the machine. The most common causes of loss of control
over the machine are for example:
- Loss of wheel traction.
- Excessive speed, not adjusting speed to current conditions and terrain properties.
- Sudden braking where the wheels lock up.
- Using the machine for purposes for which is was not designed.
2.1.5 AFTER FINISHING WORK WITH THE MACHINE
!Always maintain the machine and its accessories clean and in good technical condition.
!The rotating blades are sharp and may cause injuries. Whenever handing the blades always use protective gloves or wrap the
blades.
!Regularly check the nuts and bolts securing the blades so that they are tightened with the appropriate amount of torque
(6.3.6).
!Pay special attention to lock nuts. After the nut is loosened a second time its locking capability is reduced and therefore it needs
to be replaced with a new one.
!Regularly inspect all components and if necessary replace those that need to be replaced based on the
manufacturer's recommendations.
!Regularly lubricate the recommended parts of the machine according to the lubrication plan ( 6.4).
2.2 |SAFETY INSTRUCTIONS FOR WORK ON SLOPES
Slopes are the main cause of accidents, loss of control over the machine or subsequent roll-overs, which may lead to serious
injuries or death. Mowing on slopes always requires an increased level of attention. If you are not sure, or it exceeds your ability, do
not mow on slopes.
!Riding mowers can be used on slopes with a maximum incline up to 12° (21%) and only in the direction of the fall line, i.e.
upwards or downwards. More information 5.5.4.
!When changing direction increased care is needed. Do not turn on a slope unless it is absolutely necessary.
!Watch out for holes, roots, uneven terrain. Uneven terrain may cause the machine to turn over. High grass may conceal hidden
obstacles. Therefore, remove all foreign objects from the area where you wish to mow in advance.
!Select such a speed so that you do not need to stop when on a hill.
!Perform all movements on a slope slowly and smoothly. Do not make sudden changes to speed or direction.
!Avoid starting up or stopping on a slope. In the event that the wheels lose traction, turn off the power to the blades and drive
slowly down the hill.
!Start driving very carefully and slowly when on a slope so that the machine does not "skip". Always reduce the machine's driving
speed before a slope, and especially when driving down a hill lower the driving speed to minimum to take advantage of the
braking effect of the transmission.

2.3 |CHILD SAFETY
If the riding mower operator is not prepared for the presence of children then a tragic accident may happen. The movement of
a riding mower attracts the attention of children. Never assume that children will remain in the location where you last saw them.
!Do not allow children without supervision in areas where you are mowing grass.
!Always be prepared - if children approach you then turn off the machine.
!Before and while reversing look behind you and at the ground.
!Never transport children, they may fall and seriously injure themselves, or they may dangerously interfere with the riding mower
controls. Never allow children to operate the machine.
!Pay increased attention in places with limited visibility (near trees, bushes, walls, etc.).
2.4 |FIRE SAFETY
When reversing the riding mower it is necessary to adhere to fundamentals and regulations for work safety and fire protection
relating to work with this type of machine.
!Regularly remove flammable substances (dry grass, leaves, etc.) from the area around the exhaust, engine, battery and
anywhere, where they could come into contact with petrol or oil and subsequently catch on fire and so result in a fire on the
machine.
!Allow the riding mower engine to cool down before parking it in an enclosed location.
!Pay increased attention when working with petrol, oil and other flammable substances. These are very flammable substances,
the fumes of which are explosive. Do not smoke during this work. Never unscrew the petrol tank cap and refill with petrol while
the engine is running, if the engine is hot or if the machine is in a closed location.
!Check the petrol lines before using and do not fill the petrol all the way up to the bottleneck of the tank. The heat generated by
the engine, sun and the expansion of the fuel may lead to the petrol overflowing and a subsequent fire. For storing flammable
substances use containers designed for this purpose. Never store a canister with petrol or the machine inside a building near
any source of heat. Pay increased attention when working with the battery. The gas inside the battery is highly explosive,
therefore do not smoke in the vicinity of the battery and do not use an open flame so as to avoid serious injuries.
