5.2 INSPECTION AND REPLACEMENT OF CIRCULAR SAW
BLADES
DANGER
Before inspecting or replacing the circular saw blades, turn off the tractor/carrying
vehicle's engine and remove the key from the ignition. The branch cutting saw must be
mounted on the hitch of the multifunction arm's head in transport position and
supported on stable and strong supports.
Regularly inspect the circular saw blades. Visually inspect the technical condition of the
circular saw blades, their teeth and fixing. The circular saw blade teeth should be sharp and
properly shaped according to the dimensions specified in FIGURE 5.3. The circular saw
blade teeth should be sharpened and levelled by a qualified specialist. A bent, broken or
damaged circular saw blade must be replaced with a new one provided by the manufacturer
of the branch cutting saw (part number: 267N-00000010). Before proceeding to replace the
circular saw blade, clean the residue of cut material from the blade.
In order to replace the circular saw blade proceed as follows (FIGURE 5.2):
•
rotate the circular saw blade (1) so that the recesses on the distance disc and on the
circular saw blade housing are aligned;
•
lock the circular saw blade (1) by inserting the wrench (2) into the recesses on the
distance disc and on the circular saw blade housing;
•
dismount the protective cover (3) by unscrewing three bolts (4);
•
unscrew two set screws (5) from the clamp nut (7);
•
undo the clamp nut (7) using the special wrench (6). Mount the wrench on the clamp
nut (7) using two bolts (included in the set of wrenches) screwed in place of the set
screws (5).
•
remove the clamp (8);
•
remove the circular saw blade (1) from the drive module axle.
In order to install a new circular saw blade (1), perform the same operations as in case of
disassembling but in the reversed order.
