Assembly
Figure 2 - Assembling the Wheels
1. Slide the spacer (a), the wheel (b) and the push nut (c) over the
end of the axle in the order shown. Make sure the spacer (a) is

stable surface to assemble the wheels.
2. Lightly tap the assembly aid (d) with a mallet to secure the
push nut (c) over the end of the axle. Repeat steps for other
wheel.
Figure 3 - Assembling the Axle
1. Slide both ends of the axle up into the slots (a) as shown. The
lipped side of the spacers (b) should go inside of the axle
slots.
2. Make sure each axle plate is oriented and located as shown (L
and R). Secure each plate with two (2) screws. Snap the wheel
caps (e) over the ends of the push nuts.
Figure 4 - Assembling the Handle
