MAGIC SQUARES MAINTENANCE
LUBRICATION
The mounting posts for the plexiglass number discs
should always have a touch of lubricating grease.
Clutch washers also require lubrication, and when
necessary, "Neatsfoot Oil" should be applied. Dry
clutches causes loss of clutch action and binding,
this is hard on motor unit. Upon replacement of
old clutches the new ones should be first soaked in
"Neatsfoot Oil", wiped clean of excess oil, then in
stalled.
CLUTCH WASHER REPLACEMENT
In replacing leather clutch washers, it is important
that the large hole clutch washer (P-801-598) be
placed over the large end of the nylinder, and the
small hole clutch washer (P-801-599) be placed over
the small end of the nylinder. Both washers should
face, rough side to the drive sprocket. (see Ex
ploded Drawing for Reference).
"E" DISC & SHAFT RE-ASSEMBLlNG
Drive Stud "A" must be positioned at farthest point
from shaft key-way "B" as shown in illustration.
(If assembled wrong, 180
°
off centerline "E" num
bers will not index properly.
DRIVE CHAIN ADJUSTMENT
Adjustment is made when the idler gear assembly
screws are loosened and assembly is moved gently
to the right. Adjust chain while drive motor is run
ning, this will insure needless slack between gears.
Avoid over tightening chain, this will cause need
less wear and stretch.
