Stair climber assembly
For models with 8” wheels:
1. Place axle rod through the hole closest to the inside of the axle plates. Slide the
rod through the first axle plate and then slide it through inside holes of the stair
climbers and then through the other axle plate.
2. Before assembling the wheels, keep the stair climbers moved to the middle
of the axle rod and insert the spring pins through the axle rod (Fig 2). There
are two holes in the axle rod at each end for the spring pins. You may need to
loosen one of the axle plates to get the spring pin aligned with the hole on the
axle rod. You can use a hammer to drive the spring pin through the axle.
3. Attach tops of stair climber to the frame using bolt and washer (the sides with
the red plastic insets on the stair climbers should be facing to the rear).
For models with 10” wheels:
Place axle rod will go through the hole closest to the outside of the axle plate (as shown in Figure 2), then proceed to
step 2 as shown above.
8” Wheel assembly (solid wheels)
Assemble the wheels with a washer on the inside and outside of each wheel. The
grease zerk on each wheel should be on the inside. Use a cotter pin to hold the wheel
in place, which will go into each end of the axle rod; once it is through, bend each
side using pliers.
Handle assembly
Insert the handle and tighten down bolts on each side with a 10mm wrench and # 6
allen wrench.
