1.3 General Safety Instructions

DANGER!

All brakes acting on the tires do not serve as service break but are only designed as
parking brake (wheel lock).

DANGER!

Don’t use the footplates as a step stool when getting into or out of your wheelchair.

These should be flipped and swung out of the way first, if possible.

DANGER!

Depending on the diameter and setting of the casters as well as the setting of the
wheelchairs center of gravity, the casters may flutter when driving at higher speeds. This
can lead to blocking of the casters and cause the wheelchair to tip over. Therefore,
ensure that the casters are properly adjusted.

DANGER!

Get to know how the wheelchair reacts when the center of gravity shifts; for example on
slopes or inches or when clearing obstacles such as steps and curbs. This should be done
only with assistance from another person.

DANGER!

When reaching for objects in front, to the side or behind the wheelchair, do not lean out
of the wheelchair too far as this will shift the center of gravity and cause the chair to tilt
or tip over.

DANGER!

Lift the wheelchair only by parts that are firmly attached.
For example, don’t lift the wheelchair from footrest or the flip-up side panels.

DANGER!

To avoid hand injuries, don’t grasp between the rear wheel and the wheel lock when

driving the wheelchair.

DANGER!

Always make sure that the quick-release axles are correctly set on the rear wheel. The
rear wheel must not be removable without the button of the quick-release axle being
depressed.

3 Delivery, Preparing the MRI Wheelchair for Use

When the T-150 MRI Wheelchair arrives, inspect all shipping containers for evidence of physical
damage. If there are any dents, screeches or other evidence of physical damage to the boxes,
contact Troyka Med or your local dealer, note the damage on the shipper’s copy of the bill of lading
and file a claim against the shipper.

In the case of shortages or malfunctions, notify Troyka Med immediately to arrange for
replacement or repair. If purchased through a distributor please contact them for assistance. Save
all packing containers and materials for the Troyka Med MRI wheelchair in the event it needs to be
returned to Troyka Med for replacement or repair.

DANGER!

Risk of injury: Do not hold on to other moveable parts than the ones described.

T-150 MRI wheelchairs are generally delivered completely assembled and folded. Three simple steps to
prepare it for use.

1. When folding or unfolding the wheelchair, hold it only at the indicated positions.

2. While standing next to the wheelchair, tip it slightly toward you and press on the edge of the seat

upholstery closest to you. The wheelchair will unfold up to its entire seat width

3. Mount and push the footplates down

The overhang of the back upholstery attaches easily to the seat upholstery with a hook-and-loop closure.
We recommend keeping the overlong attached at all times.

4 Adjustment/Assembly Instructions

T-150 MRI wheelchair has many options by which it can be customized to your needs and preferences. We
recommend consulting with your distributor or service team of Troyka Med to determine which wheelchair
settings will work best for you.

INFORMATION!

The following tools are required for repair and maintenance:

 Allen wrenches, size 4 and 5 mm
 Torx allen wrenches sizes x 30
 Open-end wrenches, sizes 19 and 24 mm
 Socket wrenches size 10 and 19 mm
 Philips head screwdriver
 Tire levers
 Torque wrench

4.1 Adjusting seat height and seat inclination

The higher the rear wheel is attached to the frame, the more the seat inclines downward. This positions the
user deeper and more firmly into the seat. However, rear wheels that are attached high at the frame also
make the wheelchair more prone to tilt backward. A careful and synchronized height adjustment of both the
rear wheels and the casters will allow adapting the seat height to the users’ requirements.

INFORMATION!

Please note: when the rear wheel position is changed, the angel of the caster axle in
relation to the ground also changes. Ensure that this angle is always approx. 90
degree wide. The wheel lock must be re-adjusted as well.

INFORMATION!

Make sure to firmly retighten all screw and nuts after making adjustments. The
proper torque for the screw connection of the rear wheel adapter is 8 Nm. The
proper torque for the screw connection of the fitting is 50 Nm.

4.2 Changing the Wheelbase

Shifting the rear wheel backward lengthens the wheelbase and thus provides for gre3ater stability of the
wheelchair. Shifting the rear wheel forwards relieves the load on the casters. This increases the
maneuverability of the wheelchair. The caster wheels can then also be lifted more easily to clear obstacles
such as curbs or steps

DANGER!

Please note: if the rear wheels are in a more forward position and the user’s body is

not appropriately positioned, the user may tip backward-even on level ground!

INFORMATION!

Make sure to firmly retighten all screws and nuts after making adjustments. The
proper torque of the screw connection of the rear wheel adapter is 8 Nm.

4.3 Adjusting the caster wheel journal angle

After the rear wheels have been mounted in the appropriate position, the caster wheel journal angle must
be readjusted.

The treaded axle should be as horizontal as possible in relation to the ground to ensure optimal driving
behavior of the wheelchair. The caster adapter allows for continuous angle adjustment.

INFORMATION!

Loosen the two screws between caster adapter and frame.
Now you can move the caster adapter along with the frame tube. The level
(included in delivery) will help you position the threaded axle as vertically to the
ground as possible.

INFORMATION!

Make sure to firmly retighten all oval head screws. The proper torque is 8 Nm.

4.4 Wheel Lock

To change the position of the rear wheels, first, loosen the attachment screws of the clamping adapter of the
wheel lock and push the wheel lock forward. Then reposition the rear wheels. The wheel lock should then be
remounted such that the distance between the tires and wheel lock bolts is maximum 4 mm when the wheel
lock is not activated. Check the effectiveness of the lock devises regularly. To ensure MRI safety and
sufficient braking effect, use only original rear wheels with an appropriate radial excursion of maximally
±1mm.

INFORMATION!

Make sure to firmly retighten all screws and nuts after making the adjustment!

INFORMATION!

Tighten the wheel lock attachment with a torque of 10 Nm.

that this medical product as a whole conforms to the requirements of the European Directive for Medical
Products 93/42/EEC.

The proper function of the wheelchair, especially of the breaks, should be checked before every use. Safety

the non-magnetic one.

The following table lists functions which the user must check at the indicated intervals.

To ensure smooth operation at all times, some parts of the wheelchair can be maintained by users with
minimal technical skills:

 Hair and dirt frequently collect between the caster forks and the casters; over time, they make the

caster stiff to operate. Remove the casters and thoroughly clean the forks and casters using a mild
household cleaner.

 If the wheelchair gets wet, it is recommended to dry it off as soon as possible.
 Screw connections should be periodically checked for tightness, especially during the initial period of

use or after making adjustments to the wheelchair. If a screw connection comes loose repeatedly,
please consult your local distributor or Troyka Med service team.

Cleaning and Disinfection

Clean the cushions and upholstery with warm water and mild detergent. Remove spots with a sponge or a
soft brush. Rinse with clear water and left the components dry.

Note!

Don’t use any aggressive cleaners, solvents, or hand brushes etc.

Water-based disinfectants (e.g. Sagrotan original concentrate) should be used for disinfection.

The manufacturer’s instruction for use must be observed.

Note!

Before disinfecting, the pats and handles must be cleaned.

Plastic parts, frame parts, and the chassis and wheels can be cleaned with a mild cleaner and a damp cloth.
