Assemble units as described herein only. To do otherwise
may result in instability. All screws, nuts and bolts must be
tightened securely and must be checked periodically after
assembly. Failure to assemble properly, or to secure parts
may result in assembly failure and personal injury.
Note: The instructions to follow
outline removal and replacement
of field replaceable parts. Your
replacement procedure may not
involve all procedures/parts
outlined below.
1. Carefully turn chair upside down
on to a clean protective surface,
such as a sturdy table-top. Take
care to not damage the chair
(Figure 1).
2. To remove the base, hold the
base up with one hand, then with
a weighted rubber mallet in the
other hand, tap on the bottom of
the cylinder until the base comes
off (Figure 1).
3. Next remove the cylinder by lifting
up and holding it firmly, then tap
on the bottom of the mechanism
until the cylinder releases (Figure 1).
4. To remove the back assembly, first
remove the four back attachment
screws using an Allen wrench.
Once the screws are out, tap on
the plastic pieces in the middle
and the back will come off
(Figure 2).
5. One at a time, remove the arm
attachment screws using an Allen
wrench. Hold each arm while
removing the screws as the arm
assembly will drop out easily
(Figures 3 & 4).
6. To replace a damaged arm
assembly with new, use the screw
removed in step 5 above and
reverse the process (Figures 3 & 4).
7. To replace with a new back
assembly, align mounting holes
of new back with mounting holes
of seat assembly. Then, re-use the
screws removed in step 4 above.
Take care and twist in all four
screws before tightening any. Use
Allen wrench to tighten screws
securely (Figure 2).
