4.1.2 Attaching
 Mount and dismount the tree stump grinder on an extension arm with the latter mounted on a
tractor, and when the whole aggregation is prevented against moving by the tractor’s parking
brake engaged.
 When connecting hydraulic hoses to the tree stump grinder's nozzles wear protective gear such
as eyewear, gloves and clothing.
 Mount and dismount the tree stump grinder from extension arm on an even and paved surface
while keeping particular attention.
 Tractor's 3-point linkage should be adjusted with tensioning chains, so as to ensure a stiff
connection between the tractor and the extension arm, onto which the tree stump grinder is to be
mounted.
 Tractor with the mounted aggregation of the extension arm and the tree stump grinder should be
balanced so as to provide the stability of the aggregation including the tractor and the extension
arm.
 In order to mount the tree stump grinder on the extension arm use original fittings and safety
devices only.
 When connecting hydraulic hoses to the tractor's hydraulic connectors make sure, that the
hydraulics on either the tractor or the extension arm aggregate are pressure free.
 Before connecting the hydraulics reduce pressure in hoses.
4.1.3 Operation
 When operating on public roads always respect the local traffic regulations and provisions
concerning warning lights.
 Admissible slope, on which the machine is able to operate is provided by the Manufacturer.
Angular value for safe operation on slope is 8º(Journal of Laws No. 12/98 item 51.)
 Unauthorised personnel and animals should keep away from the grinder for a safe distance,
which is at least 10 m from the machine. Keep particular attention when operating near roads
and lanes, where presence of unauthorized personnel is likely (Journal of Laws No. 12/98 item
51.)
 When operating the aggregation of arm and grinder, make sure the tractor is always equipped
with operator's cabin.
 Before operating, the machine should undergo a technical inspection. Pay particular attention to
the condition of basic connections of the machine’s assemblies as well as proper mounting of
the machine to the tractor.
 Each time before operating, check condition of the cutting knives along with cutting disk, and if
need be, deliver it for recovery or replace.
 Before starting the tractor, make sure that all drives are disconnected and control levers for
hydraulics are in neutral position.
 Before moving, make sure whether there are no unauthorised personnel directly nearby the
machine, give an acoustic signal.
 Never leave the tractor’s engine running without any supervision. Before leaving the tractor,
turn the drive off, set the aggregation of tractor and extension arm and the tree stump grinder in
a standstill position and remove the ignition key (Journal of Laws No. 12/98 item 51.)
 For any break in the machine operation, disconnect the drive (Journal of Laws No. 12/98 item
51.)
 Tree stump grinder should be operated with the PTO shaft running at 700-1000 rpm (applicable
for the SaMASZ extension arm).

 Operate the grinder only when the tractor is not moving, and move the grinder only by the
extension arm and adjust the operation to conditions such as size and number of tree stumps to
be ground.
 Do not operate the tree stump grinder after dusk.
 Do not leave the aggregation of tractor and extension arm on slopes or other inclinations
without providing any additional protection.
 Do not operate with damaged or missing guards (Journal of Laws No. 12/98 item 51.)
 In case of a fatal failure, stop the machine's drive, turn the tractor's engine off and take out the
ignition key. Then call for technical service, and if an accident (in this case: road accident)
occurs, respect first aid rules and contact responsible authorities.
4.1.4 Inspection and repair
 Perform any inspection, repair and maintenance works as well as cleaning parts or assemblies
when the drive is switched off and there is no pressure in the hydraulics, having taken the
ignition key off and set the aggregation of tractor and machine in a standstill position (Journal
of Laws No. 12/98 item 51.)
 Inspect bolts and other fasteners regularly. Do not operate with damaged or worn fasteners.
 Do not operate with damaged or worn fasteners. When the rubber guard shows signs of ageing
(e.g. micro cracks over the surface), it should be replaced.
 Do not perform any repair works underneath the lifted machine’s assemblies, unless protected
against free falling (Journal of Laws No. 12/98 item 51.)
 Replace damaged or worn (aged 5 years or older) hydraulic hoses and other hydraulic parts as
recommended by the Manufacturer.
 Never repair damaged hydraulic hoses with tape.
 Before any operation, check the condition of cutting knives. If blunt, rotate the knife by 1/3 turn
(3 sharp cutting edges per a single knife can be achieved), or handle it for a recovery. Damaged
or worn blades must be replaced.
 Use only original spare parts ordered at our store or at your dealer.
 During operation, maintenance and adjustment, always wear protective gloves, shoes and
clothing without loose elements, belts, etc. Always respect warnings on safety labels attached to
the machine.
 When operating the hydraulics, always wear protective eyewear and gloves. Hydraulic oil
leaking under pressure (40 MPa) may penetrate the skin and cause its irritation thereafter. In
such case, visit a doctor immediately.
 In the event of a serious failure, please call for technical service, and if an accident (in this case:
road accident) occurs, respect first aid rules and contact responsible authorities.
CAUTION:
Prior to maintenance and repair the machine, turn off the engine of tractor. All
rotating parts should be stopped.
4.1.5 Replacement of damaged or worn parts
 Any works related to replacement of worn or damaged parts should be done only after the
machine has been switched off, and having previously learned the contents herein.
 When conducting repair works or replacing worn or damaged parts wear protective gloves,
protective footwear as well as protective clothing without any loose elements.
 When operating with the machine lifted up, protect it properly with supports and when
replacing parts with sharp edges, use personal protective equipment and corresponding tools.
