Circular saw -

- 14 -
Use any transport protective means as provided for controlling and design of the extension arm
to transport the aggregation of the arm and the saw.
For transport dismount PTO shaft and protect circular blades against accidental exposure to
contact with any third party.
Bear in mind the proper marking and lighting of the tractor-circular saw aggregate as 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.

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 170' (50m). 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 Ø120
(4.7'' / 12 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.
