4. SAFETY PRECAUTIONS
WARNING!
Circular saw poses danger when used. It can exclusively be operated by a trained
person or a person under training and under supervision of an experienced
operator.
Each circular saw operator should be fully aware of potential risks resulting from
its operation and should know how these are avoided.
Whenever the circular saw is used, always make sure to use proper individual
protection equipment.
❑Safety helmet
❑Ear protection
❑Protective gloves
Operator should always have a first-aid kit within his reach (Journal of Laws
No. 12/98 item 51.).
4.1. General safety principles
4.1.1. Connecting
❑Mount and dismount the circular saw on an extension arm with the latter mounted on the tractor,
and when the whole aggregation is arrested by the tractor’s engaged parking brake. Prior to starting
the tractor, set the arm's foot in a position that is convenient for mounting the saw.
❑When connecting hydraulic hoses to the circular saw’s nozzles wear protective eyewear, protective
gloves and protective wear.
❑Mount and dismount the extension arm-circular saw aggregate to and from the tractor on even and
paved surface while keeping particular attention.
❑Never stand between the tractor and the machine, unless the tractor-extension arm aggregate is
protected against moving with the tractor's parking brake.
❑Tractor's 3-point linkage should be adjusted, so that stiff connection between the tractor and the
extension arm, onto which the circular saw is mounted, is the result.
❑Tractor with the mounted aggregation of extension arm and the circular saw should be balanced
in the manner, which allows stability of the whole aggregation of the tractor and extension arm.
❑Mount the circular saw on the extension arm only with use of genuine fittings and safety devices.
❑When connecting hydraulic hoses to tractor hydraulic connectors make sure, that either tractor or
the extension arm aggregate hydraulics are pressure free.
❑In order to have the drive transmitted from the tractor onto the extension arm aggregate, use a
manufacturer-recommended PTO shaft only.

OPERATOR’S MANUAL
4.1.2. Transport
❑When driving on public roads always respect the local traffic regulations concerning warning lights.
❑When approaching transportation of the aggregation of the arm and the circular saw, take off or
partially disconnect PTO shaft from the tractor’s side.
❑Prior to the transport protect circular blades with an additional protective guard.
❑When transported the arm-saw aggregate shall have mobile warning light device and warning
triangle mounted for a slow driving vehicle.
❑When transported the machine should always be set in transport position. See Fig. 6.
❑Any modifications in the circular saw's position are possible only if no vehicles or unauthorized
personnel are around (children in particular).
❑Driving speed should always be adjusted to current road conditions.
❑Do not exceed permissible speed of 25 km/h.
4.1.3. Transport and delivery
Both carrier and driver are responsible for machine transportation. All equipment and parts must
be secured for transport. In order to move the machine onto any other means of transport follow the
below rules.
❑When hoisting do seize the points indicated for this purpose on the machine and labeled with a
hook symbol (Fig. 4) only,
Fig. 4. Manner of lifting saw when moving
❑For hoisting do use hoists with capacity bigger than the circular saw's weight as indicated on its
data plate. It also applies to the necessary cables and chains,
❑Transport belts, belt suspensions, ropes cannot be damaged. Whenever damages to these parts are
found, replace these with new ones,
❑When mounting slings, chains, clamps, etc. always keep in mind the centre of gravity of the machine
(Fig. 5) ,
❑For seizing the machines pick lines of adequate length, so that the angle between them was no
greater than 120°, and the angle of inclination between the cable and the vertical was no greater
than 60°,
❑collapsible elements should be locked in transport position,
❑when relocating the machine onto another vehicle, there should be no unauthorized personnel
permitted to remain within the danger area,
❑The machine should be protected from shifting on the vehicle's trailer.

responsibility of the person in charge of the machine moving.
4.1.4. Operating
❑During operation of the machine the Regulation of the Farm Ministry and Food Economy
(Rozporządzenie Ministra Rolnictwa i Gospodarki Żywnościowej) from 12.01.1998 dealing with
safety and hygiene during the operation of tractors, machinery, tools and equipment used for
farming (Journal of Laws No. 12/98 item 51), should be observed.
❑Before operating the circular saw learn content of this operator's manual and follow rules provided
by the Manufacturer herein.
❑Apart from this operator’s manual follow the instructions as given in the extension arm operator's
manual.
❑Do not use the circular saw for any purposes other than its intended use.
❑Do not introduce any design modifications without prior arrangements with the Manufacturer.
❑Failure to learn the operator’s manual can result in damaging the circular saw.

OPERATOR’S MANUAL
❑The machine must not be operated by minors or handicapped persons.
❑Observe all safety signs, warnings or warning signs placed on the machine.
WARNING!
Be certain that children and animals are at a safe distance away from the
machine.
❑Unauthorized personnel and animals should be present in safe distance, which is at least 50 m
from the circular saw. Keep particular attention when operating near roads and lanes, where
presence of unauthorized personnel is likely.
❑When operating the arm-saw aggregation, the tractor should always be equipped with operator's
cabin.
❑Prior to operating, the machine should undergo a technical inspection paying particular attention
to condition of basic connections of machine’s assemblies as well as proper mounting of the
machine to a tractor.
❑Prior to commencing any works condition of circular blades must be examined, and if need be,
replaced with new ones.
❑Prior to starting tractor make sure that each drive is disconnected while control levers for
hydraulics are in neutral position.
❑Prior to moving make sure whether there are no unauthorized personnel directly nearby the
machine, give an acoustic signal.
❑The tractor’s engine must never be left running without supervision. Before leaving the tractor, turn
the engine off, set the aggregation of tractor and extension arm in standstill position and take the
ignition key out.
❑It is forbidden to drive the circular saw backwards when operating.
❑Cutting with the circular saw can only be started when PTO rpm rate reaches 540 or 1000 rpm
(depending on the extension arm used).
❑Perform any circular saw maneuvering only from the operator’s seat. DO NOT control from outside
the tractor’s cabin.
❑When cutting, the circular saw should be set so that the cutting plane is always parallel to the
tractor's driving direction and, if possible, perpendicular to the road surface (Fig. 7).
❑Operating speeds of the tractor and the extension arm-circular saw combination should be
adjusted to operating conditions such as: size and volume of the branches being cut, degree of the
ground unevenness.
❑It is recommended to keep low operating speed –with low tractor gears engaged. Applying higher
speeds may lead to damaging the circular saw and also the extension arm.
❑Do not operate the circular saw after dusk.
❑DO NOT leave the aggregation on any slopes without any additional protection.
❑The operator is not allowed to leave the tractor while driving.
❑In the event of any break in the equipment operation, turn off the drive.
❑Bear in mind that when operating and transporting the machine in areas where high voltage lines
are present, special caution should be exercised due to possibility of contacting the aggregate with
the lines.
