1. General Information for Stand-up Wheelchairs
Dear LEVO Customer
We would like to thank you for putting your trust in LEVO AG.
As well as performing all the functions of a sitting wheelchair, the LEVO enables you
to stand up on your own. LEVO manufactures only wheelchairs with stand-up option.
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.
Yours faithfully,

7. Important Safety Information before use
The stand-up wheelchair LEVO active-easy LAE allows manual driving with a self-
actuated, manual stand-up mechanism. The stand-up actuator is operated by the user
pushing down on 2 ratcheting hand bars. 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 LAE is suitable for the user in terms of physical condition, personal
safety and 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 LAE 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 LAE 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
LAE (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.
The LEVO LAE 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 mechanism 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.

12
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 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 LAE
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. Seating adjustments
All LEVO wheelchairs are custom made and come fully assembled. Minor
adjustments concerning the axles and the seat support may only be
conducted by your local specialist dealer. The same applies to other general
adjustments as for example the tilt angle of the chair.
Any sort of alterations on the wheelchair as well as disregarding the weight
limits are strictly prohibited. Incorrect adjustments can lead to major
injuries. Contact your LEVO dealer regarding any adjustment.
8.1. Seat inclination
The standard pre-set angle of inclination is approx. 5° to the rear. By altering the
height of the axle holder it is possible to re-set the backrest angle between 0° and 8°
to the rear. To ensure these alterations do not compromise safety in the standing
position, the front wheel forks must be adjusted appropriately. These adjustments
should only be carried out in consultation with your LEVO dealer!
8.2. Position of the rear wheels
By re-setting the axle holder either further forwards or further backwards, you are
able to increase or decrease your LEVO tendency to tip over. To avoid accidents
(tipping over) we recommend the fitting of anti-tip wheels. Please consult your LEVO
dealer!
8.3. Position of the front wheels
The correct positioning of the front castors depends on the height of the rear wheels
and is crucial in ensuring a safe standing position. Please consult your LEVO dealer!

14
8.4. Backrest angle
The standard pre-set angle between backrest and seat is 90°. It is possible to re-set
this angle either 5° further forward or 5° further back.
These adjustments should only be carried out by your LEVO dealer!
•Take off the main wheels.
•Release the screw in the 3-position slot at the hinge right
and left with a 4mm allen key.
•Take off the screws including the distance bush.
•Set in the screws and distance bushes at the preferred
angle 85° or 95° or back to 90°.
•Tighten the screws right and left.
•Attach the main wheels.
Attention: After adjustment check that the plunger on the hinge is fully
locked in place and that the backrest is fully secure.
8.5. Backrest and Seat Upholstery
The backrest upholstery can be adjusted using the Velcro
fasteners. The backrest can be tightened (for a more upright
seated posture) or relaxed (for more back support).
The seat upholstery can be similarly tightened or released by
use of Velcro fasteners and should be as tightened as
possible. Depending on the height of the cushioning, it may
be necessary to loosen the upholstery to be able to lower the
cushioning down between the two seat supports.
Depending of the seat depth, adding or removing one or two Velcro straps is required.
When adjusting the seat depth please ensure that the flap of the backrest upholstery
covers the seat by a minimum of 12 cm.
8.6. The calf/heel strap
The purpose of the calf/heel strap is to prevent the legs
and/or feet slipping backwards. It is fitted behind the heels
or higher. By making use of the Velcro fastening it is
possible to alter the length of the strap and to ensure the
ideal position for the feet on the footrest. Ideal positioning of
the feet is vital in ensuring a good standing position. Please
consult your LEVO dealer!

15
8.7. Seat cushion
There is a choice of various different seat cushions, governed by your individual
needs. The Velcro fasteners fitted to the surface of your seat should allow you to
attach the majority of seat cushions securely. The Velcro fasteners prevent the
cushion from slipping out of place even when you are standing up. The height of the
footrest should be adjusted to take into account the height of a given seat cushion.
Please consult your LEVO dealer!
8.8. Footrest
The height of the footrest is important for a good sitting position as well as for the
standing position. The footrest is set according to the details given in the original
order form and can be adjusted within the limits of those settings.
Contact your LEVO dealer regarding any adjustments.
There is a choice of 5 different heights for mounting the footrest.
•The 5 different positions of height to which the
footrest can be adjusted.
•Unscrew the four oval head screws at the outer side
of the footrest using a 4mm hex key and set the
footrest either higher up or lower down.
There are three possible footrest angle variations:
•Foot angle 100°
•Foot angle 90° (Standard)
•Foot angle 80°
•Release the four screws at the out side of the
footrest using a 4 mm hex key and remove the upper
ones. Set the footrest at the required angle and
tighten the screws.
The footrest angle is set as standard at 14° to the floor. With the footrest in the
lowest possible setting, an angle of 4° is the only practicable variation as the footrest

16
otherwise touches the ground before the leg supports which reduce the standing
stability!
With the second lowest setting the only variations are 4° and 14°, for the same
reasons.
For all higher footrest settings there are all three angle variations possible.
Caution: Check the standing stability after adjustment to avoid
tipping forwards.
8.9. Chest Belt
The chest belt is fixed by Velcro to the backrest upholstery and is adjustable in the
height

17
9. Adjustments for seating and standing position
Adjustments for sitting and standing position must be carried out by your local LEVO
dealer. Also, if you should feel uncomfortable in any of the upper mentioned positions,
please do not hesitate to contact your local LEVO dealer.

10. Safety Information Standing
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 situations, it is necessary
that the user is allowed to stand only under the supervision of an accompanying
attendant or caregiver.
Regarding visual and cognitive capability the physician, therapist or dealer must
decide whether the LEVO LAE can be used by the user depending on its environment
and in terms of personal safety.
There are many moving components on the chair that interact and change positions
as the chair cycles from sit to stand. Please take care to avoid any pinching or
squeezing of the client or attendant.
To insure standing stability and avoid risk, the LEVO LAE must be located on flat and
level surfaces with the brakes engaged. Be certain to check for objects which would
prevent the legrests from reaching the ground simultaneously preventing solid
contact.
Damage may occur if the standing system is operated without a person in the chair.
The chair is engineered so that the client’s weight acts as an assist to the electric lift
actuator and gas struts as the chair returns to the seated position.
It is imperative that before attempting to stand, that the knee support and the chest
strap are properly positioned to restrain the client and are secured to the wheelchair.
The restraints must be worn over clothing to prevent any skin irritations.

20
11. Brakes
The brakes lock the rear wheels to secure the LEVO LAE against unintended
movement.
By pushing both brake levers forwards you should be able to lock the brakes
immediately.
The efficiency of the brakes is dependent on tyre pressure and profile, which should
be checked regularly.
Caution: Wet tyres or surfaces also have a detrimental effect on brake efficiency.
Be sure to re-adjust the brakes when altering the position of the wheel axle.
11.1. Brake adjustment
The wheelchair should be unoccupied when dismantling the brakes. Secure the
wheelchair in such a way as to prevent it moving when the brakes are removed.
Release the brake as much as possible.
Release the cylinder screw on the brake itself (see figure on the left).
Adjust the position of the brake and leave a gap of approx. 10 - 15mm between the
brake shaft and the tyre, then tighten the cylinder screw (see figure on the right).
Test if the brakes function correctly afterwards.
If you want to increase the brake force, position the brake shaft closer to the tyre, if
otherwise leave a larger gap between the brake shoe and the tyre.
