sembly by removing the two bolts securing the alu-
minum coil cap to the coil housing.

super glue to prevent the knot from working loose
or use a lighter to melt the knot to prevent loosen-
ing.

form a point before it completely cools.
7. Remove crane housing cap by loosening the (2)
thumbscrews.
8. Feed the pointed end up through the hole in the

bottom side of the crane housing cap.
10. Feed the pointed end up through the hole in the
bottom of the crane assembly housing.
11. Feed string over first string guide then under the
next string guide.
12. Finally, feed the string through the hole in the side
of the string spool, attached to the motor shaft, and
tie another knot. (Once again, either use super
glue to prevent the knot from working loose or use
a lighter to melt the knot to prevent loosening)
13. The string is now properly strung.
14. Re-attach the claw assembly to the crane assem-
bly using the two bolts that were removed in step 4.
15. Re-install the crane assembly into the game and
set it in the home position with the claw assembly
hanging in the prize chute.
16. Turn on the game and the crane will automati-
cally rewind the string properly.
MOTOR REPLACEMENT
1. Remove all A.C. power from the game.
2. Unlock and open front door.
3. Remove crane and / or wagon assembly as previ-
ously stated. NOTE: What is removed depends on
which motor has gone bad.
4. Loosen two thumb screws securing crane housing
cap in place and remove. NOTE: This step is only
for the 2 motors in the crane assembly.
5. Remove drive o-rings and wheels from the bad mo-
tor.
6. De-solder the motor leads from the bad motor.
NOTE: Be sure to note which wire goes to which
motor lead, for if they are re-installed backwards,
the motor will run opposite of its intended direction.
7. Carefully remove the bronze bushing supporting
the motor shaft of the bad motor. NOTE: This step
is only for the 2 motors in the crane assembly.
8. Remove the 4 bolts securing the motor to the hous-
ing.
9. Carefully remove the bad motor.
10. Re-assemble in reverse order using new motor.
NOTE: When motor is completely re-installed,
place one drop of thread lock on each of the 4 bolts
that secure the motor in place to prevent the bolts
from backing out.
PRECAUTION
When installing a new motor in any of the three loca-
tions, please note that the 4 screws, if tightened too
much, could mis-align the motor and cause binding. It
is advisable that you tighten the 4 screws just enough
to keep the motor from moving. Then apply a small
drop of (Blue) loctite on the back side of each of the 4
screws to prevent the screws from loosening. When
the motor is installed properly, it should draw .5 amps
or less when running at proper 22 volts.
