5. General Information for Stand-up Wheelchairs
Dear LEVO Client,
We would like to thank you for putting your trust in LEVO and our product.
The LEVO Summit standing wheelchair is a unique aid for use by those with the inability to
stand and/or walk on their own. As well as performing all the functions of a lightweight
wheelchair, the LEVO enables you to stand up on command.
Please read this manual carefully before using your LEVO. It contains important information
necessary for the successful operation of your wheelchair.
It is possible that achieving the standing position may load the body in a way that it is
perhaps not used to. Therefore, it is necessary to consult with your doctor or physical
therapist to confirm that there are no contraindications such as contractures,
orthostatic hypotension, osteoporosis or other conditions present.
In the case of strong or sudden spasms, cramps or similar conditions, it is necessary
that the user is allowed to stand only under the supervision of an accompanying
attendant or caregiver.
As a LEVO customer, you have the opportunity to make a valuable contribution with the on-
going future development of our products. Your suggestions are always appreciated. This
will insure that LEVO continues to offer the most functional products available and provides
for the widest possible range of needs.
Sincerely,
LEVO AG EU SRN: CH-MF-000008751

6. User Profile - LEVO Summit EL
LEVO Summit clients are those who prefer a lightweight manoeuvrable wheelchair and will
benefit from the comfort and function of the electric stand feature. Both contribute to
enhance your lifestyle in work and leisure time situations.
The model Summit combines all the positive qualities of a manual driven wheelchair with
the convenience of safe standing at your fingertip. The user-friendly electric standing system
(with gas spring assist), elevates you effortlessly to any standing angle to 86°upright, with
ankles/hips/shoulders in a straight line.
Depending on the client’s capability, the LEVO Summit is available with a choice of a rocker
switch, a toggle switch or a remote control which can also be operated by an attendant.
In all circumstances, it is best that a client be evaluated by a rehabilitation mobility team as
to the appropriateness of a standing wheelchair. This team should consist of family
members, a doctor, a therapist and a dealer.

7. Important Safety Information before operating
LEVO Summit EL
The stand-up wheelchair LEVO Summit EL allows manual driving with an integrated,
battery-powered stand-up actuator. The stand-up actuator is operated by pushing a rocker
switch or by operating an optional manual joystick controller, either by the user or by an
accompanying person. The seat moves to any position between completely seated, as with
any ordinary wheelchair, and standing up to 86°.
Moving to a standing position may load the body in a way that the body is perhaps not
used to. Therefore, before using a stand-up wheelchair, consult your doctor or physical
therapist to make sure that no contraindications such as strong contractures or osteoporosis
are present. Without a prescription by your doctor or physical therapist, there are risks of
injury. All user and medical instructions must be strictly followed.
In the case of strong or sudden spasms, cramps or similar, the user should stand under the
supervision of an accompanying person.
Regarding visual and cognitive skills, the physician, therapist or dealer must decide whether
the LEVO Summit EL is suitable for the user in terms of personal safety and depending on
the intended environment and use.
Please take care to avoid trapping yourself or other persons in the mechanism during
elevation or descent. Especially take care of the sections between the seat and the
mainframe to avoid any kind of injury.
The LEVO Summit EL must be driven to level and solid ground before elevating the user to
a standing position (Caution: risk of tipping over!).
The brakes of the LEVO Summit EL must be activated before elevating to a standing
position (Caution: risk of tipping over!).
The standing function should not be operated without a person seated in the LEVO Summit
EL (risk of accident!).
It is absolutely essential to mount the knee support and the chest strap correctly before you
use the stand-up function! You should never go into standing without these safety restraints
securely in place (risk of accident)!
The restraints must be worn over clothing to prevent any skin irritations.

9
The LEVO Summit EL should not be lifted by the armrests. The armrests are designed for
high, downward load, but not for upward, tensile loading.
Driving the wheelchair must always be in the completely seated position so that the load
can be distributed to the frame. Otherwise there are risks of damage to the seating system.
Please avoid any abnormal and unforeseen loads like torques or shear forces. Additional
load at the armrests or backrest, fixing for transport without the dedicated equipment etc.
should be strictly avoided! The wheelchair could be damaged causing injury to the user or
other persons.
For amendments and adjustments to the mechanics or to the electronics and for
maintenance work, please contact your dealer.
For safety reasons, adjustments to the stand-up mechanism and functionally-related parts
must only be performed by trained personnel.
Standing wheelchairs require professional adjustment to safely and comfortably be used in
the standing position.
All available standard sizes guarantee the passage of escape routes marked as wheelchair
accessible, as wheelchair seats or connecting routes in public transport. Please take note of
and ask about escape routes. Size-dependent adjustments are therefore strictly forbidden,
as these may put these features at risk.
All adjustments outside the standard configurations which convert wheelchair characteristics
are strictly forbidden as this can cause risk of serious injury.
Be aware that the surface temperatures can increase when exposed to external sources of
heat (e.g. sunlight).
Please avoid exposing the wheelchair to extreme heat. Please also note that, if exposed to
high humidity or salt, the wheelchair should be cleaned and dried frequently.
The resistance to ignition of materials and assemblies are as follows:
-Plastic parts according to UL 94-V0
-Upholstery according to EN 1021-2
Please note that strong electromagnetic fields can cause interference with the control or
operation of the standing-actuator function.

10
Please note that all product safety information can be obtained on our website, from your
dealer and in the user manuals which will be available at your retailer. In case of product
recalls you will be informed by your retailer, as the LEVO products are sold exclusively
through retailers.
Owners or users of LEVO products that have acquired a second-hand LEVO product from a
source other than a recognised retailer must contact LEVO and/or a LEVO Summit EL
representative to ensure correct fitting and to perform necessary safety checks. Adjustments
to the mechanism must be performed only by trained personnel.
Please note that the product life under normal functional use and care is around 7 to 10
years. If the wheelchair is used not according the instructions or is subject to extreme or
difficult conditions, the life may be shortened.

8. Initial operation
8.1. Connecting and charging the battery
•Make sure the actuator jack is plugged into the
battery box.
•Connect the charger to the wall socket and wait
for the LED to light up in green.
•Pull out the charging plug from the rear side of
the backrest (behind the upholstery) and plug in
the charger connector.
•The LED turns to red and indicates the charging
process.
•The battery needs to be charged until the LED
light on the charger turns to green. This normally
takes about 1 ½ hours.
•After charging, replace the plug behind the
backrest upholstery.
CAUTION:

12
•Only use the original LEVO charger delivered with the chair. Other chargers may
harm the electrical system.
•The actuator must not be operated while charging.
8.2. Folding down the backrest
•Grasp the cord in with one hand and twist to
release the back locking pins.
•With the other hand, push the backrest forward.
Backrest upright Backrest folded
CAUTION:
•Release the cord and ensure that the pins are locked on each side.

13
8.3. Rear wheel inspection
The LEVO Summit EL is equipped with quick release rear axles that allow the wheels to be
removed and replaced for transport or storage needs.
•To attach or take off the rear wheels, press the
release button in the center of the hub and pull
the wheel away from the chair.
CAUTION:
•When remounting the wheel, push and pull it several times to ensure the quick-
release axle has fully engaged.
•Never take off the wheels with the client in the wheelchair.
8.4. Brake inspection
The brakes on the rear wheels of the Summit EL secure the chair against unintended
movement.
•Engage the brakes by pushing the upper lever
forward. Disengage by pulling the upper lever
back.
•The efficiency of the brakes is dependent on their
position in relation to the wheel, and, the
condition of the tire tread and pressure. The
brakes should be checked regularly for proper
operation.
CAUTION:
•The brakes must be locked when standing or anytime you are transferring into or
out of the chair.
•Wet tires and/or rolling surfaces have a detrimental effect on locking efficiency.
•When modifying the forward/rearward location of the rear axle tube/wheel, it is
always necessary to re-adjust the brakes for proper locking efficiency.

14
8.5. Standing stability inspection
•The control switch on the armrest enables you to
actuate the standing mechanism up and down.
Pull the switch up to elevate the seat to the
standing position.
•When fully standing, confirm that the legrest
down post/support plugs and the front and rear
wheels are all touching the floor.
•Push the control switch down to return to the
seated position.
CAUTION:
•Only if the standing stability and all previous inspections are checked ensured, the
user can enter the chair for further inspections and adjustments.

15
9. Knee support and chest strap
Two very important safety features of a standing wheelchair are the knee support and the
chest strap. It is essential to position yourself securely and comfortably before attempting to
stand. Caution: Be mindful to carry out each step carefully before standing. If not done, the
possibility of injury is greatly increased.
9.1. Knee support
The knee support secures the lower legs in place while the chair rises to the standing
position.
•The right and left side are independently
adjustable allowing proper tension as well as the
location of the knee wedge in the center.
•A push lever on the pad releases the inserted
serrated strap to add or relieve tension by
increasing/decreasing the strap length.
CAUTION:
•The location of the kneepad on the shin is important for safety and proper standing.
Positioned with the client seated, its proper location is.
oVertical Location –approximately 1 ½” from the top of the kneepad to
bottom of the kneecap (patella). This is primarily a function of the
vertical location of the footplate.
oForward/Rearward Location –with the client sitting upright and hips set
fully toward the rear of the seat, there should be a “hand thickness”
between the shin and the kneepad. This is primarily a function of the
seat depth.
•Only adjust the knee support when the client is in the seated position. Never
attempt to do so when standing.

16
9.2. Chest strap
The chest strap secures the upper body in place as the chair rises to the standing position.
The straps wrap around the backrest tubes and are adjoined to one another with two
adjustment rings (see picture). Weaving in and out of the rings, the straps can be
lengthened or shortened adapting to different size clients. It is also possible to adjust the
chest strap up or down to accommodate need. Always make certain the straps go around
the backrest tubes and are weaved correctly through the rings.
The vertical location of the chest strap around the backrest can be adjusted accommodate
to the strength and ability of the client. Generally, the greater the disability (i.e. higher spinal
cord injury), the higher the chest strap should be accordingly located on the backrest
CAUTION:
•Make sure to retract the end of the belt back
toward the centre.
•To release the chest strap, simply pull the buckle
cover forward and away from the chest.
•To minimize irritation, avoid wearing it directly on
the skin.
Only when both the knee support and chest strap are comfortably and correctly fitted,
is the client prepared to safely stand up.
