6.4. How to set and tension the saw blade
Danger of injuries!
The tips of the saw teeth are sharp - wear safety gloves!
(Image shows open saw arm)
The saw blade should be positioned on the
center of the pulleys. In case that the saw blade
runs unevenly, check if the saw blade is in the
central position or if the deflection pulleys are
damaged / soiled.
The central position can be adjusted on the
both deflection pulleys.
•
For adjusting, release the fixing screws.
Then screw in or out somewhat the set
screws (which rest on the fore part of the
deflection pulleys).
•
Finally turn the saw blade manually (wear
gloves!) into running direction in order to
check if it runs evenly.
•
If so, tighten again all fixing screws and
close again the saw arm.
The saw blade is only tensioned at the deflection pulley with eccentric.
•
For that purpose, release the counternut; turn the eccentric until the saw blade has the
desired tension.
•
Then secure the position of the eccentric by tightening the counternut.
The tension is released in the same way (e.g. in order to exchange the saw blade).
