4 Drive Wheels (item 6)
A. Slip the first axle through one of the axle rod
carriers on an upper support.
B. Place two drive wheels onto the axle inside the
framework, making sure that the smaller, slotted
ends of the wheels face away from each other and
toward the ends of the axle (see illustration).
C. Insert the end of the axle through the
corresponding carrier on the other upper support.
The two drive wheels are now suspended on the
axle between the upper supports.
D. Repeat the procedure with the second axle and
two remaining drive wheels.
E. Add a small amount of oil or grease to the end
of the shaft. Then spin the axle to work the lubricant
inside the axle support.
STEP 2 Continued:
C. Fasten the support spacers to the upper supports,
following the same procedure used in Step 1.
D. Now is the time to secure the 8 bolts that turn
into the support spacers. Using a
3
