Preparing circular saw for operation
Prior to operating the circular saw perform the following:
Thoroughly examine the circular saw, whether it is in operating condition and has no plays and
damages. Pay particular attention to condition of bolt connections and circular blades.
Take off any locks and safety devices mounted on the arm-saw aggregate,
Connect PTO shaft to the tractor.
Upon making sure there is no unauthorized personnel around, start the circular saw with no
load and reach the max. rpm for the circular saw, and then shut down and inspect for oil leaks.
If the circular saw's condition and its idle operation raise no doubts, start cutting with the
circular saw.

Safe commissioning and shutting down
Prior to commencing operation look around whether there are no unauthorized personnel or
animals within the range of 50 m. Then position the circular saw in the desired operating position
(always parallel to the driving direction) and once completed, start the circular saw. As the required
PTO rpm rate of 540 or 1000 rpm is reached, the cutting action may be commenced.
Prior to stopping the circular saw first seize cutting by driving the circular saw into a space
with no branches or bushes around. Then turn off the circular saw drive and wait until circular
blades come to a complete stop. Now manipulating with the extension arm can be started in order to
set the arm-circular saw aggregate to transport position.

Operation
In order to provide proper high quality operation, as well as to maintain circular saw
durability follow these principles:
The circular saw can be used to cut tree branches, bushes, hedges with diameter of up to Ø190
mm (19 cm).
Do nor allow the circular saw to get jammed, what may lead to its damage.
It is recommended that the operator prior to commencing cutting sets the circular saw in an
adequate position and does not modify such position on a single go. Such manner of operation
provides work safety and treatment aesthetics.
Longer branches should be cut gradually, while beginning from the top and ending at the bottom
due to a possibility of getting the circular saw jammed in the cut material.
Bear in mind to adjust driving speed to the thickness and quantity of the branches cut at once in
order not to overload the circular saw and thus prevent it from damaging.
When cutting thick and rigid branches (e.g. dried) ease off the circular saw's moment of contact
with a cut branch by significantly lowering the tractor's speed without reducing PTO rpm rate. In
order to avoid any impact contact what may cause damage to the circular saw.
When cutting do not make any perpendicular motion with the extension arm in relation to the
cutting plane as this may lead to getting the circular saw jammed and thus damaged.
The circular saw's cutting plane must always remain parallel towards driving direction and
possibly perpendicular to the ground on which the tractor is driving.
Do not operate the circular saw with any contamination wound onto circular blades' hubs, as this
may lead to their locking.
It is forbidden to use the circular saw for cutting any non-wooden materials.
For long operating periods, it is recommended, on few-hours basis (preferably every 3-4 hours of
operation), to periodically inspect circular blades, bolt connections, as well as the circular saw
itself.
It is forbidden to operate the circular saw if damaged. In order to continue operating remove any
damages.
Blunt circular blades must be replaced with new ones.
