4.2. Residual risk
Despite the fact, that company SaMASZ– the manufacturer of the machine takes
responsibility for design and manufacturing of the rake, in order to eliminate dangerous
situations, certain risk during machine’s operation is unavoidable. Residual risk results from
incorrect behaviour of the scissor trimmer operator.
Major source of risk follows performance of these operations:
 operation of machine by minors as well as not being familiarized with operator's manual,
 operation of machine by persons under influence of alcohol or other abusive substances,
 not keeping caution while transportation and shifting of scissor trimmer during operation,
 transport of persons remaining on the machine,
 presence of persons and animals within the machine operation range,
 performing operations related to servicing and adjustment with engine on.
1. Danger of catching
This kind of risk is present when position of machine is being changed, as a result of
operating near rotating parts.
During operation, maintenance and regulations always wear protective gloves, shoes and
clothes without loose parts, belts and so on. Always comply with safety decals placed on the
machine.
2. Danger of injury and abrasion
This risk is present when replacing working parts with sharp edges, cleaning the machine,
removing the clogging and jams. During any maintenance and repair works, always wear safety
gloves.
3. Danger of cutting limbs off
Contact between cutting knives and body may lead to serious injuries, and in extreme cases
amputation of limbs or even death. Failure to pay enough attention when operating the machine
nearby unauthorized personnel may cause an accident.
4. Danger of kick
Kick is one of the most dangerous accidents which are likely when operating machine. It is
described as uncontrolled, sudden and very quick motion of an object or part of it being processed
(splinter, knurl, etc.). Direct impact of the material against human body may cause, depending on
the material weight and size, as well as speed and the impact location, bruises, injections, loss of an
eye, teeth, or even death due to damage to organs and vast internal haemorrhages.
5. Danger of irritation to the respiratory tract
Lesser threat when cutting is also a dusty atmosphere as emission of significant fractions of fine
chips and dust. The operator thus should operate in a tight cabin with proper airflow.
6. Danger of liquid ejection out of hydraulic system
During connection of hydraulic hoses to hydraulic connectors make sure, that either the
extension arm’s and the trimmer's hydraulic system is without pressure.
During operation of hydraulic system always wear protective glasses and gloves. Check
regularly hydraulic hoses.
CAUTION:
Residual risk results from incorrect behaviour of the machine operator.

5. USING OF THE SCISSOR TRIMMER
5.1. Attaching the scissor trimmer to the extension arm
In order to mount scissor trimmer on extension arm do the following in a sequence:
 place pallet with scissor trimmer on an even and paved ground,
 drive the tractor with the attached extension arm and position the mounting plate of the arm so it
matches the scissor trimmer‘s mounting plate,
 secure the tractor against moving,
 bolt trimmer‘s mounting plate to the arm's mounting plate with bolts and M14 nuts,
 connect hydraulic hoses using push-in fittings while paying particular attention so that the
scissor trimmer’s supplying hose is connected to the supply connector P(+) of the extension arm
and the scissor trimmer’s return hose to return connector T(-) of the extension arm,
 lift up the connected scissor trimmer slightly above the pallet and check all bolt connections and
whether there are no apparent damages,
 take off the cutting bars cover and next pre-start scissor trimmer in order to check whether
connections and operation are correct.
Fig. 4. Markings of hydraulic hoses
CAUTION:
When connecting and inspecting the scissor trimmer, follow any and all safety
conditions provided herein.
5.2. Transport position and drives
Transport position of scissor trimmer aggregated with SaMASZ extension arm corresponds to
the arm's transport position. See.
When mounting the scissor trimmer on other type of extension arm, fold the scissor trimmer
aggregated with the arm in the position as compact as possible.
 To transport the aggregation of arm and scissor trimmer, use any protective means as intended
for control and design of the extension arm.
 Dismount the PTO shaft for transport.
 Provide proper marking and lighting of the aggregated machines for a low-speed vehicle to
comply with road traffic provisions.
 Driving speed should always be adjusted to current road conditions.
 Transport speed on public roads cannot exceed the mean speed of 25 km/h (15 mph).

5.3. Operation
5.3.1. Basic information about the operation
In order to ensure proper high-quality operation, as well as to maintain machine's durability
follow these rules::
 respect work safety and traffic rules solely,
 scissors trimmer can cut branches with diameter up to Ø100mm (10 cm),
 keep hydraulic oil consumption for scissor trimmer’s supply pump at max. 45÷60 l/min. For
SaMASZ extension arm such demand is achieved at tractor’s PTO shaft rpm of 300-350 rpm,
 it is recommended for the operator before cutting to set the machine in an adequate position and
does not modify such position on a single drive. Such manner of operation provides work safety
and treatment aesthetics,
 longer branches should be cut gradually, starting from the top and moving to the bottom for the
likeliness of damaging the tractor by falling cut branches.
 remember to adjust driving speed to the thickness and quantity of the branches being cut at the
same time so as not to overload the scissor trimmer and thus prevent it from jamming,
 when cutting do not make any perpendicular motion with the extension arm in relation to the
cutting plane as this may damage the cutting bars
 cutting plane when using scissor trimmer should be as parallel to driving direction as possible,
 it is forbidden to operate the scissor trimmer when cutting bars are contaminated. Sand, rocks,
wires and other solid objects (non-wooden) cause accelerated blunting of blades and their
damage,
 do not operate the machine if cutting bars have significant plays on guides or there is no
lubricant in between,
 it is forbidden to use the trimmer for cutting any non-wooden materials,
 for long operating periods, it is recommended, on few-hours basis, to periodically inspect
cutting bars, bolt connections, as well as the scissor trimmer itself,
 it is forbidden to operate the scissor trimmer if any damages are found. For further operation,
immediately correct any damages,
 if cutting bars become blunt, order their recovery or replace them.

5.3.2.Initial adjustment and preparing for operation
Scissor trimmer is factory adjusted and requires no additional adjustments. If any signs of
improper operation of the machine are found, please contact the Manufacturer's service.
Before operating the machine do the following:
 set tilt by means of mounting plate tilt adjustment,
 thoroughly examine the machine for operational condition, plays and damages. Pay particular
attention to condition of bolt connections on cutting knives,
 remove any guards, locks and safety devices mounted on the aggregation of extension arm and
scissor trimmer,
 connect the PTO shaft to the tractor,
 having made sure there is no unauthorized personnel around, start machine with no load and
reach the pre-set PTO rpm rate, and then shut down and check for tightness,
 if the machine's condition and its idle operation raise no doubts, start operating.
5.3.3.Safe start up and shut down
Before operating make sure there are no unauthorized personnel or animals within the range
of 10 m. Next set the machine in the mean working position and start it afterwards.
Before stopping the machine first stop cutting by driving the scissor trimmer into a space with
no branches or bushes around. Then turn off the machine's drive. After this it is possible to start
operation of the extension arm in order to set the arm-trimmer aggregate to transport position.
5.3.4.Control
Scissors trimmer is controlled with the extension arm control panel.
5.3.5.Proceedings in case work unit is locked
 Lower adaptor onto the ground.
 Perform any works at the machine only with its drive turned off and no pressure present in the
hydraulics.
 Remove the ignition key and secure the vehicle against uncontrolled movements or unintended
start up.
 Wear protective gloves and remove the part which causes the machine's locking.
5.3.6. Dismounting machine from the extension arm
To dismount the machine from the extension arm:
 turn cutterbar’s drive off,
 drive the tractor with connected the extension arm and the scissor trimmer to the pallet. The
pallet must be placed on the equal and hardened ground,
 carefully put a scissor trimmer on a pallet,
 secure the tractor against its free runaway,
 turn the tractor's engine off and take ignition key off,
 fit a cutting bars cover,
 disconnect a hydraulic hoses,
 disconnect trimmer’s mounting plate from the extension arm’s mounting plate by unscrewing,
 carefully drive away with the tractor.
