IV. WHEELCHAIR USE & CONFIGURATION
U. Wheel Locks
WARNING: Underinflated or worn tires may cause your wheel locks to not function
properly. Failure of the wheel locks to hold your chair could cause a loss of control or fall
resulting in serious injury or death.
How to Adjust Your Wheel Locks
NOTE: Always loosen and tighten wheel hardware by alternating between the two bolts
while loosening/tightening a little at a time. This prevents overclamping on one set of
hardware which leads to binding of the fasteners and increased difficulty in removal.
1. Use a 10mm wrench or socket to loosen (do not remove) the hex bolt (Fig. 27:H) beneath the
mounting block of the base frame.
2. Slide the mount plate (Fig. 27:G) forward or rearward to achieve proper locking.
3. Retighten the hex bolt.
How to Reverse the Wheel Lock Mount
If the chair is equipped with the attendant foot lock and you are changing the wheel size, a new
linkage rod is needed. Contact your authorized supplier or Ki Mobility Customer Service to order.
1. Use a 10mm wrench to remove the nuts (Fig. 27:A) from the wheel lock studs and remove the
wheel lock mechanism (Fig. 27:E).
2. Remove the hex bolt (Fig. 27:F) and the nut (Fig. 27:I) using two 10mm wrenches.
3. Flip the wheel lock mount (Fig. 27:D) forward or in reverse.
4. Reinstall and tighten the hex bolt (Fig. 27:F) and the nut (Fig. 27:I).
5. Reinstall the wheel lock mechanism (Fig. 27:E) and fasten with the nuts (Fig. 27:A).
NOTE: The large diameter washer (Fig. 27:B) goes under the nut that covers the scalloped
hole (Fig. 27:C). Always install the wheel lock using the scalloped hole that allows the front
stud of the wheel lock mechanism to lie below the rear stud. For example, if the single hole
is toward the front of the chair, install the wheel lock so the rearmost stud of the wheel
lock mechanism is in the upper hole of the scalloped hole. If the single hole is toward the
rear of the chair, place the front stud of the mechanism in the lower hole of the scalloped
hole.
