ONLY FOR U.S.A. and CANADA VERSION
only moulder unit
At least every 2 months or 500 stops, check and adjust the electromechanic braking device.
Braking efficacy reduction can be noticed by the increase of the time required to fully stop the cutterblock/spindle
(max. time 10 seconds) in case of tool of max. size and at the maximal permitted speed.
Before carrying out any of the operations make sure to cut the main electric power and disconnect socket
T from plug S.
U.S.A. and CANADA version:before carrying out maintenance operations, adjustments or to dismount any
machine member turn main switch (Y) to 0, lock it then indicate this with a sign.
Adjustment of braking unit
Every two months or every 500 braking actions, braking unit adjustment is mandatory.
To reset the best braking torque proceed as follows:
-
insert an Allen wrench into the hole on cover for the fan in order ot reach the adjusting screw;
-
progressively screw down screw in order to join the mobile elements and to eliminate distance (brake
clearance);
-
unscrew screw by min.1/4 turn (max.1/3 turn) (corresponding to about 0.4 mm air gap);
-
turn the brake release selector several times to check that it operates correctly;
-
start and stop the motor a few times to check the correct running.
DANGER-WARNING
If the adjustment is not carried out, the machine could have these problems:
- no braking within the maximum stop times (10 seconds)
- no brake release at start command, leading to overheating of the brake and the adjusting
systems.
NOTE-INFORMATION:
if the adjustment procedure cannot correctly restore brake operation, substitute the braking unit.
