4.4.5. Angular stops adjustments
There are two fixed stops with adjustable screw on the console. The angular stop-
points setting have to be periodically inspected to prevent inaccurate angular cuts
1. In order to check angular stop settings, turn the arm to the fixed stop and put the
protractor on the saw band and vice jaw
2. If the angles are not set correctly, release the nut on the stop screw. You can set
smaller angles by tightening the screw. You can set larger angles by loosening the
screw
3. Fasten the nut again and check the angle setting with the protractor according to
procedure above
angle 0° angle 45° Angle 60°
4.4.6. Adjusting the limit switch of the saw band stretching
After the saw band is replaced, the limit switch setting must be checked out. If the limit
switch is not set correctly, the band is stretch too much or it is to loose
1. Stretch the band by means of TENZOMAT–on the optimal value
2. Release the nut on the stop screw
3. Start the driving engine. Two scenarios may occur:
a) If the engine is switched on, but it does not run, turn the screw to the left
until the engine starts to run
b) If the engine runs turn the screw to the right until it stops to run, then turn
the screw shortly to the left until the engine starts to run again
