Then the ball throw disc is pulled off the motor shaft.
(Fig. 19.a,b,)
Take away the plastic discs from the
ball throw foam (it is held together by three screws) and insert those onto the new foam disc. Fix this set
again with the three screws.
Slide the new disc onto the shaft in a way that the end of the shaft to be 0,5-1 mm out
(Fig. 18.),
and
tighten the warm screw. Then adjust the correct distance of the discs with the help of the adjusting tube
as it is described above.
−
If a
ball jam
should occur, the machine tries
automatically to remove the jam by turning the motor
and the throw discs forwards and backwards (7-8 times).
In case the feeding motor and the three throwing motors
jam for any reason the machine stops in self-defence.
Then the fault signal is the following: all the 6 yellow
lights start to flash on the control box. You have no other
choice than, to take out the head from the machine, and
take out the offending balls from the bottom part of the
robot with the help of a pencil or screwdriver, etc.
through the cleaning hole found there
. (Fig. 20.)
−
Once every 4-6 months, the stop pin, which is needed to adjust the ball throw length, needs a really
slight application of silicon oil (just enough to cover the end of the match-stick).
The pin is easily accessible in the release head. The rest of the machine needs no maintenance. How-
ever, it is recommended to remove dirt and dust from the surface of the robot with a moist cloth and a
mild cleansing agent from time to time.
