Disconnect the machine from the power supply and
secure it or turn off the main switch and lock it.
•
Insert an angled SW5 Allen key through the fan cover
and insert it into the hexagon socket of the front-side
set screw (see

15.8.1 Check the Adjustment
•
Before checking the adjustment, make sure that the belt is well tensioned (see

15.6).
•
Then reconnect the machine to the power supply or unlock the main switch and switch on.
•
Only for machines with mechanical motor brake
→
Turn the brake release switch to “ active ” position.
→
Now it must be possible to move the saw blade by hand. By turning it, you can now check whether
the brake is dragging, which means that it has been adjusted too excessively.
→
If the brake is dragging, the readjustment made must be minimally reversed again.
Cutting hazard! Wear protective gloves when handling the bandsaw blade!
•
Now turn the brake release switch back to “ inactive ” position .
•
Start the bandsaw blade and wait until the machine has reached full speed.
•
Then switch off the bandsaw and check the braking time to standstill.
•
If the braking time is still over 10 seconds, repeat the setting procedure (see section

15.8)
and check the adjustment again.
•
If the adjustment was not successful, please contact the customer service of the manufacturer.

If rattling noises occur in the area of the fan blade when turning the motor, please contact
the customer service. Possibly the brake lining is worn out.
