2. INTRODUCTION
 This operator's manual should be considered as the machine basic equipment. If the mower is
handed over to another operator, it should be in working condition, along with operator's manual,
EC declaration of conformity and its basic equipment.
 Prior to operating the machine its user must familiarize himself with this manual as well as
common work safety rules.
 The machine is manufactured in accordance with requirements of safety standards.
 Respecting recommendations herein shall ensure operation safety.
 If you have any questions related to commission and operation of the machine, please contact
the manufacturer.
 Operator's manual remains an integral part of the machine equipment.
GENERAL PRECAUTION
When operating the machine warnings and safety rules marked with this sign
herein should be respected.
CAUTION:
Operating the machine without previous familiarizing with its content as well
as by unauthorized personnel, and especially by children, is strictly forbidden.
3. PROPER USE
Arm with flail head is set on tractors with power of min (Tab. 1) Mounting the arm is
performed on rear 3-point linkage, with which are farming tractors equipped as standard. Rear PTO
must be set on 540 rpm (upon special order 1000 rpm).
Machine are designed for treatment of land drainage ditches in particular as well as mowing of
road shoulders, shredding thinner trunks (up to approx. 2 cm), small shrubs, weeds, etc. of moderate
concentration as well as mowing road shoulders, slopes, counter-slopes and ground at tractor's right
side. Moreover the mower can be used to trim hedges both in vertical and in horizontal position. The
arm can be additionally equipped with adapters offered by the SaMASZ co. Arms work properly on
grass (and other plants) with height up to 1.0 m. Heads are designed for shredding cut tree branches,
mowing weeds, shrubs and grass.
CAUTION:
Basing on experience, upon driving onto single shrub with section up to
approx. 2 cm, the tractor should be stopped for a while, until the machine
shreds the shrub at the ground, and then slowly with intervals drive forward,
so there occurs no cutterbar locking.
CAUTION:
Use of the machine for purposes other than mentioned herein is forbidden.
Different use than the above mentioned shall be considered as improper and
may lead to revoking of the warranty. The machine should be operated,
maintained and repaired only by personnel familiarized with its detailed
specifications and safety rules and procedures. Willful modifications to the
machine may lead to revoking of the warranty.
We congratulate you on the purchase of your new SaMASZ machine and wish you much pleasure and
the very best experience resulting from its operation.

Extension arm comprises the following basic assemblies:
 extension arms (3, 12),
 linkage (11) (Fig. 13),
 hydraulics with oil tank and oil cooler (9) (Fig. 11),
 control panel (15) (Fig. 10),
 multiplier with hydraulic pumps (10) (Fig. 12),
 hydraulic cylinders (1, 2, 4, 13, 14).
Extension arm is equipped with independent hydraulics with oil cooler and oil tank (9). Rotor’s
drive and arm control is possible owing to own hydraulic pumps assembly driven by multiplier (10),
transmitter’s shaft without coupling and tractor’s PTO. Controlling telescopic arm extension is
performed directly from tractor’s hydraulics by telescope’s cylinder (13), while shifting of arms is
possible owing to hydraulic cylinders (1and 2).
Controlling operation of extension arms is performed from tractor’s cabin with use of control
panel (15), equipped with a cylinder control handle and a joystick (1, 2, 4 and 14). With use of
corresponding handles, the operator can set position of machine’s movable assemblies. Tractor drives
along road’s edge while flail head mows grass.
Use of cylinder (14) controlled rotor (7) enables arm to be set in transport position. Rotor’s
cylinder (14) protects operating arms against overloading (item 6.4.7). While head’s cylinder (4) acts
as head’s rotation (6).
CAUTION:
Extension of telescopic arm causes shifting of centre of gravity of the set
(tractor, machine) what may cause alternation of its stability. It is
recommended to extend the arm just above the ground.
