4.5. Replacement, Tensioning and Adjustment of the Saw Blade
Disconnect the machine from the mains and secure it against restarting. Raise the arm to the upper position. Remove the protective
covers of the saw blade and remove the back cover of the arm. Use the tensioning star nut to loosen the tensioning wheel and the
whole blade. Take the saw blade off the wheels and push it off the guide heads (see Section 4.6.). Insert the new saw blade in the
guide heads. Put it on the wheels and tension the saw blade by a tensioning star nut.
Tension the star nut, so that the disc springs
are fully compressed (no light coming through)! In this way, you can achieve correct tensioning of the saw blade.
Remove
the protective covers of the saw blade and remove the back cover of the arm. Restart the saw blade with the START button and let it
turn once. Make sure that the blade is correctly placed in the guide heads. Restart the saw blade and let it turn once. Disconnect the
machine from the mains and secure it against restarting. Remove the protective covers of the saw blade and the back cover of the
arm. Make sure that the saw blade is correctly fitted on the guide heads and correctly installed on the wheels (see figure). If the saw
blade is not correctly placed on the wheels, loosen the tensioning star nut and, using the wheel tilt adjusting screw, adjust the position
of the saw blade on the wheel (see the picture).
Tension the star nut, so that the disc springs are fully compressed (no light
coming through)!
Remove the protective covers of the saw blade and remove the back cover of the arm. Connect the machine to
the mains and carry out a saw blade trial run. Disconnect the machine from the mains, remove the protective covers of the saw blade
and the back cover of the arm. Check the placement of the saw blade on the wheels. Repeat the procedure, if required. For a quick
check of saw blade positioning on the wheels, you can use the BLADE GUIDANCE CONTROL OPENING. Remove the protective
covers of the saw blade and remove the back cover of the arm. Connect the machine to the mains and carry out the cutting.
Caution: You can remove protective covers only if the machine is disconnected from
the mains and secured against restart.
Caution: Danger of injury by the sharp teeth of the saw blade. Use protective gloves.
Do not reach between the wheels and the saw blade.
A timely replacement of the saw blade is needed to achieve good cutting performance, surface finish quality and compliance with
workpiece dimensions. Blunt saw blades cause high consumption of electrical power, uneven cuts and rough cutting surfaces. One
of the decisive factors affecting the quality of the cut and the life of the cutting tool is the correct and sufficient saw blade tension.
