other operators.
Safety Instructions
Do not enter or reach under the machine if it is lifted and not sufficiently supported. The machine should
be supported on places marked by the symbol of a chain.
The mower should only be transported in a container or on a trailer.
Check bolt torques at regular intervals. The first check should be done after 8 operating hours. Pay
attention to the attachment of the cutting blade and the proper bolt torque. Use a torque wrench and a
specified torque of 60Nm.
The blade hub bolts and the blade bolts must not show any signs of damage or wear. The bolts must be
complete. The blade must be undamaged, evenly worn and adequately sharp. The bolts should be
tightened with a torque of 60Nm.
If you are driving the mower outside the working area with disengaged blades, always set the maximum
height of cut otherwise the blade may get damaged.
Keep the product clean after use. Do not use gasoline or similar oil products for cleaning.
Do not reach with your hands or feet inside the mower, under the mowing deck, under the engine
covers or into the transmission system.
If you are forced to reach under the machine, wait until all rotating parts (including the engine) stop.
Attention, it takes some time before blade runs down! The run-down time depends on the state and
wear of the brake/clutch. Have the brake checked at regular intervals at an authorised servicing facility.
While operating, wear closed shoes and work clothing. Do not wear loose clothes that could get caught
by the machine, short trousers or light shoes.
A local risk assessment should determine the need for a face shield.
Do not operate the machine after drinking alcohol or using medication influencing perception.
Before starting the engine make sure that the mower blade is engaged (for mowing operation) or
disengaged (for transport). The blade may be dis-/engaged and height of cut adjusted only if the engine
is shut off. When starting the engine always step aside far enough to be protected against object
accidentally thrown from the mower and to be able to stop the mower in case of an emergency. Do not
enter the path of the mower.
While operating the mower make sure that the mower is clearly visible at all times and within the range
of the remote control unit and that you can clearly recognize dangerous situations and react to them
properly. Do not abuse the maximum reach of the remote control.
When using the mower, follow all general work safety regulations.
Work with the mower may only be started if the mower is not damaged by previous operation.
Do not change the engine tuning, especially the engine speed regulator. Do not modify the exhaust
pipe.
Do not use the mower if there is less than 30% of fuel in the fuel tank.
Do not move the mower by means of towing it behind another machine.
Operating Environment
The machine should only be used by persons over 18 years of age, who have been acquainted with the
machine and the user’s manual .The remote control (further referred to as ”RC”) is considered a part of
the machine
The user’s manual must be stored in a place permanently accessible to the operator and must be
available to him at all times.
Do not allow children or unauthorised persons use the product.
Before starting to operate the machine, you have to be familiar with all the symbols next to the controls
and indicators used on the mower and the RC.

10 / 53 rev. 02-01-10-2011
the mower.
Before using the mower on a slope, make sure you test and practice your mower-control skills on flat
and level ground, which is sufficiently free and spacious. Master how to control the movement on a
surface, to mow around bushes, trees and other terrain elements and obstacles.
If you stop the mower on a slope, position the wheels across the slope and secure it against
undesirable movement by the means of the emergency brake.
While operating or transporting the mower, the operator must always have the mower in their view. The
maximum distance between the operator and the mower is 50 m /165 ft.
While using the mower follow all safety regulations given in this manual and respect local regulations
and provisions concerning noise-emissions, especially when using in hospitals, spas and other sensitive
areas.
The operator must pay attention to the area into which the mulched grass may be blown. Neither the
operator, nor any other persons, children nor animals should be allowed to enter this area. If mowing
uneven terrain the ejection and throwing of undesirable objects becomes more probable due to the
displacement of the mowing device (tilt of one side of the machine) while crossing the edges of different
terrain.
The operator of the machine may be responsible for any damage caused to third parties by operating
the machine.
The mower may be used on dry surface on slopes listed in chapter 1.2.
Before operating the machine, make sure you remove from the mowing area all loose stones, sticks,
glass, wire, bones, branches and all other objects that can be picked up by the blades and thrown or
that could damage the mower.
While operating the mower avoid obstacles, do not drive over higher obstacles (such as stones, stumps,
brick), near precipices, on unstable soil or in places where the mower could fall down or flip over.
When operating pay attention to electric power lines especially when driving beneath electric wires
where the radio signal may be lost. In such case the mower immediately shuts off the internal
combustion engine and stops all movements.
When using the machine near busy thoroughfares make sure that the mower does not endanger (by
throwing undesirable objects) passers-by or their property. Choose a suitable working procedure (see
chapter: Operating the mower).
The operator/user is responsible for the safety of persons that enter the working area of the machine.
Stop your work if these persons enter the working area.
The transportation of persons, animals or loads on the mower is prohibited.
Do not place any objects or tools on the product.
While operating, especially in windy conditions, choose the operator’s position carefully so as to keep
the operator away from the stream of exhaust gas, dust or mulched grass.
Stop work and clean the machine and its cooling surfaces several times while working in dusty
conditions to avoid over-heating during operation. If necessary, clean the machine and its cooling
surfaces several times while working. The dust layer must not exceed 1 mm.
Refuel only when the machine is off –before operating, if possible –and the fuel tank is cold. Always
keep at least 30% of the fuel in the tank. If you need to refuel during your work, do not fill the fuel into a
hot tank or while the engine is still hot. Let the machine cool down.
Do not overfill the fuel tank.
Never refuel while the engine is running.
Before refuelling push the STOP button on the control panel of the mower.
Do not start the engine if you find spilled fuel, open vessels with fuel or other combustible objects or
gases in the immediate proximity of the mower.
Do not refuel near open fire.
Do not place this product near open fire or other sources of heat.
While operating or immediately after shutting the machine off do not touch those parts of the machine
that heat up during operation. This concerns mainly the engine exhaust pipe, metal parts of the
hydraulic drive and metal parts of the internal combustion engine.
While operating do not touch the high voltage conductor leading to the sparking plug.

Operation manual –Spider MINI
11 / 53 rev. 02-01-10-2011
After starting the engine, test the correct functioning of the emergency engine stop on the radio
transmitter. This function should be checked at least once during every shift and every time you enter a
new area for mowing or mulching.
Before starting your work test the correct functioning of the safety components (EMERGENCY STOP)
on the mower.
Never leave the engine running without supervision.
If the engine is running, do not put aside the transmitter and do not touch or move any parts of the
machine.
Always stop the engine when leaving the machine, secure it against starting by pushing the red
EMERGENCY STOP button on the control panel of mower and by removing the key. Never leave the
transmitter next to the mower, but put it in a different, properly secured place inaccessible to third
persons.
Do not engage the mowing blade until immediately before mowing and only when the engine is turned
off.
Shut off the engine and disengage the mower blade and remove the key from the ignition every time:
- You clean the machine
- You remove dirt from the mower deck (grass or debris)
- You run over an unknown object and need to check for possible damage or to carry out a repair
- The machine unusually intensively vibrates and you need to find the cause
- You repair the engine or other parts of the mower (also unplug cables from spark plugs).
While operating, avoid mole-hills, concrete bases, guard-stones, stumps, loose stones and curbs.
These must not come into direct contact with the blade as they could cause serious damage. Do not
drive the mower into heaps of sand, gravel or other material. These may also compromise the mower
stability.
The mower may only be operated during daylight or under very good artificial light conditions.
Do not use the mower in limited visibility (dusk, fog, heavy rain etc.)
Do not let the engine run in enclosed spaces. The exhaust gases contain CO. They damage health and
can ultimately cause death.
The engine should only be started and operating in open spaces. If the engine is started and operated
in enclosed spaces, the exhaust gases must be conducted away by the means of prolonging the
exhaust pipe outside the enclosed space. Proper ventilation and fresh air supply must be secured in
order to prevent the accumulation of CO.
Before storing the machine in a closed space, let the engine and the hydraulic drive of the machine cool
properly.
Regularly remove all combustible objects (dry grass, leaves...) from the areas around the exhaust pipe,
engine, alternator and battery. Cleaning may only be performed when the mower is turned off.
Always control the machine from a working station, which gives you a perfect view of the whole working
area and of the machine.
While working, change your working position to have a perfect view of the mower at all times.
When operating the mower on slopes never enter the space directly below the mower or the area to
which the mower could fall.
The working position should be far enough (maximum 50 m / 165 ft.) to prevent the operator from
getting hit by objects that may be accidentally thrown by the mower.
Do not operate the mower if you cannot see it (behind terrain obstacles, corners of buildings, hidden in
grass etc.)
Safety Decals
Before starting the mower, check the state of the safety labels. If any labels are damaged or missing,
contact your dealer and replace such labels on the machine. Get thoroughly acquainted with these
labels. The placement of the labels on the machine is obligatory.

7. SAFETY SYSTEMS
7.1. MOWER SAFETY ELEMENTS
The mower is controlled by a radio remote controller. This means that the operator is not permanently near the
mower and cannot use the controllers placed directly on the mower. For the safety of the operator as well as
other person the following chart lists various situations and protective measures taken:
Command EMERGENCY STOP (automatic or manual) has the following effects:
1. Engine is stopped
2. Wheel steering is blocked
3. Wheel drive is blocked
4. Starter is blocked
5. Engine brake is engaged
6. Ignition is turned off
EMERGENCY STOP command is activated if:
1. mower get out of the signal range
2. radio connection is interrupted / interfered with
3. another machine on the same frequency channel works nearby
A safety block prevents the engine from starting if:
1. there is no connection between the RC and control unit of the mower
2. confirmation button on the RC is not pressed
3. drive servomotor is not in the neutral position
4. engine brake is activated
In case the mower rolls over the engine brake is activated automatically. This ensures quick stopping of
the mowing blade.
