WARNING! Danger of injury by moving parts!
• To avoid personal injury and injury to other individuals from moving wheelchair parts such as wheels,
power legrests, and/or tilt or elevate modules, always be aware of your surroundings, especially when
children are present.
• Pinch points may occur during the operation of your power legrest. Always keep hands and fingers clear
of moving parts to avoid injury.
WARNING! Risk of injury, tipping or damage
• When travelling down a ramp or incline, never attempt to drive with leg rests in the extended position.
WARNING! Any sudden or gradual deterioration in the function/performance of your power
positioning system (i.e. increased actuator motor/gearbox noise, rattling, sloppiness, etc...) must
be reported to your Dealer immediately.
• A complete wheelchair inspection by a qualified technician is recommended to ensure there is no
unusual wear and tear, or physical damage that requires servicing and/or repair.

inspection
General Safety Warnings! (...cont’d)
WARNING! ThefollowingguidelinesshouldbeadheredtowhileoperatingyourMotion Concepts
power positioning system to avoid damage or injury and ensure safe operation:
• Never operate the tilt, elevate seat or power elevating legrest function while underneath a fixed object such as
a table or desk.
• Never use the footplates as support during transfers. When transferring in or out of the seating system,
ensure that footplates/foot platforms are in the ‘flipped-up’ or ‘swing-away’ position (where applicable).
• Never exceed the maximum allowable weight capacity for your power positioning system
• Never allow items (i.e.; posture belts, backpacks, coats, etc...) to be trapped under your seat when tilted,
or beneath your power legrests when extended, otherwise damage to the system may occur.
• Never allow your power center mount legrest to be used as a tie-down point in a vehicle. Use only
the designated anchoring points on the power wheelchair.
• Never use you legrest footplates/foot platforms to open doors or move obstructions.
• Never operate your power positioning system while driving your wheelchair.
WARNING! Risk of Serious Injury or Damage
Operating the wheelchair with insufficient ground clearance between the footplates and the
ground/floor may cause serious injury or property damage.
• While the wheelchair is in motion, ALWAYS maintain a minimum ground clearance of 3 inches, or the
minimum ground clearance stated by wheelchair base manufacture (whichever is greater).
• If necessary, elevate the front rigging or tilt the seat to achieve the proper ground clearance prior to driving
the wheelchair.
• Test to ensure the wheelchair does not dip forward and allow the footplates to touch the ground while it is in
motion. Make further adjustments when necessary.
WARNING! Risk of injury or damage
• Following any legrest adjustment ALWAYS inspect the wheelchair to ensure the front rigging DOES NOT
interfere with the wheelchair chassis or front casters, and that the footplates do not collide with the ground.

Each legrest extension bar is independently adjustable to accommodate a wide range of knee-to-heel (KTH)
lengths. The set screw slides up and down inside the adjustment slot on the upper legrest housing to allow
infinite KTH adjustment within the slot length. There are four extension bar lengths available to accomodate
a KTH range from 8½” - 20” (22-51cm). The adjustment range for each individual extension bar is as follows:
Short: 8½ -12” (22-31cm), Med: 10 -14” (26-36cm) Long: 13 -17” (33-43cm) X-Long: 16 -20” (41-51cm)
2.3 Legrest Extension Bar: Knee-to-Heel (KTH) Adjustments
Adjusting the KTH Length: (Tools Required: 5mm hex key)
Note: When possible, the client should be seated in the chair during the legrest set-up/ KTH adjustment.
2.3.1. Working on one legrest at a time, loosen the locking clamp assembly so that the legrest extension bar
will slide freely up and down.
2.3.2. Adjust the legrest (extension bar) to the desired KTH Length*, then retighten the clamp assembly to
secure the legrest extension bar into place.
*Note: The final KTH length may be affected by the set-up/angle of the footplates. Additional fine-tune KTH
adjustments may be required following the final footplate set-up. Refer to Section 2.4 for footplate adjustments.
NOTE: Your legrest has been factory pre-assembled using the appropriate length extension bar
needed to achieve the KTH Length requested at the time of order. If at any time you require a
different sized extension bar, please contact our Customer Service Department for assistance

2.4 Footplate Adjustments
Footplate Adjustments:
Tools Required: 4mm hex key, 7/16” (12mm) wrench, standard screwdriver
2.4.1 By altering the mounting position*of the clamping block (A), the footplate
can be adjusted forward or backward (relative to the legrest extension tube) in
1” (26mm) increments. (*note: the clamping block can also be inverted (rotated
180 degrees), in order to achieve a variation in fore/aft adjustment).
2.4.2 By loosening the clamping block, the entire footplate can be adjusted
inward or outward (in relation to the extension tube) along the pivot bracket
post (B).
2.4.3 The heel strap position can be adjusted front to back as necessary via
mounting holes in the footplate (C); Adjustments are in 1” (26mm) intervals.
2.4.4 The footplate angle (front to back) can be adjusted by loosening the
clamping block and rotating the clamp around the pivot bracket post (D).
2.4.5 The lateral (side-to-side) footplate angle can be adjusted** via the
nylon set-screw located inside the pivot bracket (E). By adjusting the set
screw depth, the footplate angle can be adjusted to achieve an angle greater
than or less than 90 degrees as needed. (**note: set-screw adjustment
