4.1. General safety rules and regulations
The following descriptions are for your safety: They must therefore be read
carefully and applied every time you use the machine.
 The machine has been designed for use by one single operator.
 When using, servicing, repairing, moving or storing the machine, the operator must wear safety
footwear, safety gloves plus ear protection and dusk mask if necessary.
 During use, the machine may give rise to dust, especially if the soil is dry. You are advised to
use a tractor with a cab fitted with filters in the ventilation system. Failing this, wear a dust
mask with filter to protect your respiratory tract.
 Front axis of the tractor should be weighted to keep the balance. If need be, use front wheel
weights.
 In order to keep steering conditions, impact on front axis should be at least 20% of the complete
tractor.
 Be extremely careful whenever using hydraulic lift lever or buttons. Any operation with
hydraulic lift lever should be done from operator’s seat; DO NOT move the lever from outside
of a tractor.
 In case of tractors equipped with EHR, operating with hydraulic lift is done by the buttons
mounted outside the tractor’s cabin. When operating be extremely careful.
 Locking pawl line and “field edge” mechanism line (in the case of the P4-420 tedder) should be
mounted with relevant tolerance in the tractor cabin
 When moving from work to transport position, remove the entire PTO shaft or at least one end
of the shaft from the tractor’s PTO so it cannot turn.

any damaged protective means should be replaced with a new one.
 Start mowing only when tractor’s PTO reaches its normal rpm.
 No person (except operator) should stand within danger area which is a minimum of 170' from
any operating part, especially when operating near roads and in areas with stones and other
debris. Be certain that children and animals are at a safe distance away from the machine.
IMPORTANT: Maintenance and adjustment should ONLY be done after the following has
occurred:
 tractor’s engine has been stopped and ignition key has been taken out,
 all rotating parts have come to complete standstill (NOTE: arms will rotate for
several minutes after engine is turned off).
 Before starting work and periodically thereafter, replace any damaged, missing and/or worn
tines.
 When driving on public roads always comply with local traffic regulations, especially those
concerning warning lights.
 When the tedder is lifted for repair on 3-point linkage, it should be secured against falling by
mechanical support or by chain.
 The bolts and other fasteners have to be periodically checked and, if necessary, tightened or
replaced. DO NOT work with damaged or worn fasteners.
 Never lift the tedder on tractor linkage when the drive is operating and the rotors are rotating.
 When operating the tedder, the tractor should always be equipped with operator protection that
is required by laws and regulations.
 Never start the tedder when the tedder arms are off the ground.
 Before you start the tractor make sure that all drives are turned off and the levers that turn the
hydraulics are in neutral position.
 Never leave tractor’s engine running without supervision. Before you leave the tractor, turn off
the engine and remove the key from tractor’s ignition.
 DO NOT operate the tedder when driving the tractor backwards.
 Permissible inclination of the tedder on a slope when working and during transport is 8°.
Exceeding this incline can result in tedder tipover.
 Never stand between tractor and tedder unless tractor and tedder are secured against moving by
the tractor’s brake.
 If any maintenance must be done under an elevated tedder, it must be blocked or otherwise
secured against falling.
 When the parts of the tedder need replacement, use only original spare parts as described in the
spare parts list. Pay particular attention to PTO shaft’s guards and tedder’s and tractor’s spline
shaft guards.
 Hydraulic hoses are potentially very dangerous. Do the following to minimize any hazards:
 Hydraulic hoses should be periodically checked and if any damage to the hoses have
occurred or if they have been used more than 5 years, replace with new ones.
 Never use scotch tape to repair hydraulic hoses.
 When connecting hydraulic hoses to tractor’s hydraulic connectors, make sure that
the tractor’s or tedder’s hydraulic system is not under pressure.
 The tedder should be stored under a roof and in a way as to not be hazardous both people or
animals.

 In the event of an accident involving this tedder in a field or on a road, follow all applicable first
aid procedures and contact SaMASZ technical service.
 Tedder should be kept clean, so as to avoid danger of fire.
4.2. Qualifications of operator
To provide safe machine operation each person being the machine operator must meet the
following requirements:
 Operator should hold driving license, have ability to drive vehicles safely and know road traffic
rules.
 Operator must be in proper physical condition to be able to operate the machine.
 Operator must not be under the influence of alcohol, drugs and medicines, which all have
influence on vehicle driving and machine operation.
 Operator should be familiarized with this manual and follow its provisions.
 Operator should be familiar with working principles of both the vehicle and the machine, and be
able to recognize and avoid hazards resulting from operation of the aggregate.
4.3. Conditions of mounting tedder on tractor
 Prior to the mounting operation, be sure that the tractor and tedder hitches are compatible and
that the tractor's hitch load is adequate for the machine which is to be mounted or attached.
 Prior to mounting the machine, examine the technical condition of the tedder's hitch assembly
and tractor's 3-point linkage.
 Use only genuine cotter pins to mount the tedder on a tractor.
4.4. Transport
The lifting, handling and transporting operations can be very dangerous unless they are carried
out with the utmost caution. Have all persons not involved in the actual work move away from
the area and limit the zone where the operations are to be carried out. Also make sure that the
area in which the operations take place is clear and that there is a sufficient escape route, i.e. a
free, safe zone to which the operators can quickly move if the load should fall.
The safety hooks and ropes used to lift the machine must be of an adequate carrying capacity.
To minimize the risk of serious injury or death, do the following:
 When the machine is converted from the transport position to the work position and vice versa,
you could be pinched or crushed by some of its parts. Take extra care when carrying out these
maneuvers and have all persons keep well clear of the danger zone.
 Do not change position of the tedder until there are no people or animals around (pay particular
attention to children).
 Before transporting the tedder make sure that the locking pawls are properly latched in the
transport position.
 While transporting the tedder, put a warning plate with combined lights and reflectors and
warning triangle on the tedder.
 During transport, always put the tedder in its proper and safe transport position. See section 5.3.
