Required Items:
3" Wheels (#4) X2
Bolt Wheel Assembly - Rear Wheel (#15) X2
•
Insert the Bolt through the hole in the leg. Thread the Jam Nut (Inner)
completely & tighten securely - use the Allen Key (#12) to secure the Bolt
while tightening the Jam Nut (Inner) with a wrench.
•
Place the remainder of the hardware components onto the Bolt in the
order as shown (Pausing at the Lock Nut stage). Use the Allen Key (#12) to
secure the Bolt while tightening the Lock Nut with a wrench.
NOTE: The rear wheel requires tension in order for the chair to perform as
designed. The rear wheel shall "TURN" when pressure is applied (It should NOT
spin). Adjust as necessary.
•
Once the appropriate tension has been set with the Lock Nut - thread the
Jam Nut (Outer) onto the Bolt and secure it up against the Lock Nut tightly.
To do this, hold the Lock Nut in place (Do not re-tighten Lock Nut) with one
wrench and tighten the Jam Nut (Outer) using the second wrench (See
Diagram A).
•
Use a hacksaw to cut off excess Bolt. Attach plastic cap.
