STEP 3: Axle & Drive Wheel Assembly
Select:
• 2 Axle Rods (item 5)
• 4 Drive Wheels (item 6)
1) Slip the first axle through one of the axle rod carriers on
an upper support.
2) 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).
3) 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.
4) Repeat the procedure with the second axle and two
remaining drive wheels.
5) 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 4: Drive Handle Assembly
Select:
• 1 Drive Handle (item 3)
• 1 Grip (item 8)
• 1 Grip Cap (item 9)
• 1 #6 Screw (item 11)
1) Slide the Grip onto the end of the Drive Handle.
2) Push the stem of the Grip Cap into the end of the Drive
Handle, aligning the holes.
3) Secure the Grip Cap to the end of the Drive Handle with
the #6 Screw. Tighten the Screw until just snug. Note:
The head of the Screw will be in the hole of the Drive
Handle, locking the Grip Cap in position.
STEP 5: Spring Pin Assembly
Select:
• 1 Drive Handle Assembly (step 4)
• 4 Spring Pins (item 10)
1) Decide which corner of the assembly the drive handle is to be positioned on. (Any of the
four corners will accept the handle assembly. The decision is entirely a factor of your
convenience.) Insert the shaft of the handle into the end of the axle rod at the corner.
2) Line up the holes in the handle shaft and the axle, then using a hammer, gently drive a
spring pin through all holes.
3) Drive a spring pin through the holes in each of the three remaining ends of the axle rods.
To hold the drive wheels properly, the spring pin should extend an equal amount on each side of the rod at all four corners.
4) Move each drive wheel into position against its corresponding spring pin, lining up the slots in the drive wheel with the pin.
Slide the wheel over the pin at each corner.
