Step 4
– Height Adjustment Tube and Ankle Holders
TIGHTEN ALL NUTS AND BOLTS AT
THIS TIME
1. Pull out the Adjustable Ankle Holding
Tube (5) and turn it 90 degrees and re-insert
it horizontally.
Make sure the holes on the
square tube are facing up
.
NOTE
: There is a spring pre-installed inside
the tube which should not be removed.
2. Install the Footrest (4) into the Height
Adjustment Tube (3) using Bolt (40), Metal
Bushing (39), Washer (19),and Lock Nut (21).
We recommend installing the Footrest (4) using
the lower hole. While in use, if the lower hole
setting is too tight and causes too much
discomfort, adjust to the higher hole.
4. Slide the U-Shape Holder (52) with Metal
Cover (53) onto each end of the Adjustable
Ankle Holding Tube (5). Make sure the Metal
Cover (53) wedges into the slot provided on
Adjustable Ankle Holding Tube (5).
Pull the Ankle Holding Adjustment Knob (37) up
and make sure the Adjustable Ankle Holding Tube
(5) slides smoothly inside the outer tube. Release
the Knob and lock it into one of the holes.
3. The U-Shape Holders (52) with Metal
Cover (53) are pre-installed on the Rear
Ankle Holding Tube (10). You must
squeeze one set (52&53) firmly to loosen it
from the wedge and remove it from the slot
that locks the part into place.
With both slots facing
UP
, insert the Rear
Ankle Holding Tube (10) into the Height
Adjustment Tube (3). Insert the Bolt (40)
with the Metal Bushing (39) into the
bigger
hole
at the bottom of the Height
Adjustment Tube (3) and tighten them with
a Flat Washer (19) and a Lock Nut (21).
Re-install the U-Shape Holder (52) with
Metal Cover (53)
.
Make sure the Metal
Cover (53) wedges into the slot provided on
Rear Ankle Holding Tube (10). See detailed
drawing.
