4 USING THE WHEELCHAIR
Getting into your wheelchair
Take off the leg rests (see chapter 4.5).
If possible, place the wheelchair’s rear wheels against a solid
wall.
Apply the parking brakes to lock the wheelchair in place.
Stand as close as possible to the wheelchair. Turn around, then
carefully move backwards until your legs touch the edge of the
seat.
Now grab the armrest with your hands.
You can now sit down slowly and safely.
Swivel both the leg rests back to the front in the direction of
travel. Listen and feel for the click to ensure that the leg rests are
correctly engaged.
Finally, fold both the foot plates downwards using your feet and place
your feet on the foot plates (see chapter 3.3).
Getting out of your wheelchair
Carry the procedure out in the opposite sequence.
WARNING
Do not stand on the foot plates or footboard while getting up or sitting
down. They are not intended to bear the full weight of one person.
NOTE
To transfer sidewards, the side panel must be swivelled up (see chapter
4.2).

4.7 Driving on gradients and uneven
ground
Potholes and uneven ground can cause the
wheelchair to tip over when driving over ramps,
slopes, gradients and kerbs.
Lean your body forwards when driving upwards
over a step or slope. (1 & 2, fig. 11)
Lean your upper body further backwards when
driving down slopes and steps. (3 & 4, fig. 11)
WARNING
Always drive up or down slopes/gradients in a
straight line and at a reduced speed. Do not dri-
ve over slopes or gradients obliquely as this in-
creases the risk of tipping over.
WARNUNG
If you brake the wheelchair for a long time
using the handrims, e.g. when driving downhill,
a lot of frictional heat is generated on the
handrims. Wear suitable gloves.
4.8 Loading the wheelchair
Additional loads (backpacks or similar objects)
up to max. 5 kg can be hung from the push han-
dles as long as the max. user weight is not ex-
ceeded.

4.6 Propelling and slowing down the
wheelchair with the push rims
The wheelchair is pushed and slowed down us-
ing the push rims. Grip the push rims with your
hands with your thumbs pointing forwards on
the push rims (see fig. 10).
WARNING
Ensure that your thumbs do not touch the tyre
casing of the wheel whilst the wheelchair is in
motion.
To propel the wheelchair forwards: Push both
wheels forwards evenly.
To propel the wheelchair backwards: Push both
wheels backwards evenly.
To stop the wheelchair: Close your hands around
the push rims and gradually increase the pres-
sure of your grip.
To steer to one side: Slow the wheel on the side
to which you wish to turn.
To turn the wheelchair on the spot: Push one
wheel forwards and the other wheel backwards
at the same time.
fig. 10
WARNING
Risk of trapping: Between the tyre and sidegu-
ard/armrest!
WARNING
During hard braking manoeuvres the push rims
can become quite hot.
WARNING
Hanging loads on the wheelchair increases the
risk of it tipping over backwards.
That is why DIETZ recommends using anti-tip-
ping supports.

4.10 Drum brakes for an attendant
(optional)
WARNING
In models without drum brakes, the accompa-
nying person must be physically capable of bra-
king the wheelchair by themselves.
The wheelchair is optionally available with drum
brakes for an attendant. The drum brakes enable
the wheelchair to be slowed in a controlled man-
ner while in motion. The drum brakes can also be
used as additional parking brakes.
Stopping the wheelchair:
Pull evenly on both brake levers (1, fig. 14).
Parking the wheelchair:
1. Pull on both brake levers (1, fig. 14).
2. Push the safety catch away from yourself
until it engages (2, fig. 14). The drum brake is
now locked.

4 USING THE WHEELCHAIR
4.9 Parking brakes
The wheelchair has one parking brake on either
side. They can be used to park the wheelchair
safety.

brake blocks the wheel (1, fig. 12).
2. Press the brake lever further forwards until
you feel it engage (2, fig. 13).

WARNING
Do not use the parking brakes to stop the
wheelchair during motion as this may cause the
wheels to block. Due to the immediate locking
of the wheels, you may no longer be able to
control the direction of travel.
NOTE
Use both parking brakes when parking the
wheelchair. This ensures that the braking force
is evenly distributed on both rear wheels.

4.12 Transport
Transport of the wheelchair without user
To transport the wheelchair in a car, airplane, train or simply to create space,
the wheelchair can be folded and separated into portable elements without
any tools. It then only takes up a very small amount of room and is easy to
store. Please check that the packing dimensions comply with the transpor-
tation requirements of the respective airline/railway company.
TOMTAR MR-S folded W/L/H in mm = 310 / 945 / 800
TOMTAR MR-LG folded W/L/H in mm = 310 / 945 / 800
Please pay attention to the following points when transporting the wheel-
chair without a user:
1. Fold the wheelchair for transport. (Chapter 3.1)
2. Carry the folded wheelchair by holding the front of the side frame and
the push handles.
3. Remove any components that can easily come free from the wheelchair
(e.g. leg rests, accessories) and store them safely.
4. Lash the unoccupied wheelchair securely in place.
5. The wheelchair must not be loaded during transport.
6. The wheelchair can be transported upright with and without rear
wheels. (Chapter 4.10 - Removing and attaching rear wheels)
7. The wheels must be kept attached to the wheelchair if it is transported
lying on its side.
8. Activate the locking brakes when transporting the wheelchair with rear
wheels.

4 USING THE WHEELCHAIR
Attaching the wheelchair
restraint systems
Only a 4-point wheelchair restraint system with
lashing straps that is certified in line with
ISO10542 and designed for the total weight of
the wheelchair must be used to secure the TOM-
TAR MR-S/ MR-LG without a power hub.
The 4 lashing strap anchor points on the wheel-
chair are labelled with a hook symbol (see exam-
ple in illustration (A) and (B)).All 4 anchor points
must be used. It is mandatory to position the
wheelchair in the direction of travel in line with
ISO10542 (WTORS). Under no circumstances
must the wheelchair be strapped in place using
other attachment points (e.g. anti-tip bar, arm-
rests). No modifications must be made to the
transport anchor points of the wheelchair with-
out the permission of DIETZ.
The wheelchair restraint system must be installed
in the vehicle in line with the manufacturer’s as-
sembly instructions.
(A) Front anchor points on the wheelchair
(B) Rear anchor points on the wheelchair
(A) (B)
WARNING
The TOMTAR MR-S/ MR-LG is tested in line with
the ISO standard 7176-19 / ISO10542 in the
direction of travel. For reasons of safety, it must
not be used/attached with the wheelchair user
facing away from or sideways to the direction of
travel.
fig. 17
4 USING THE WHEELCHAIR
Wheelchair as a car seat
Wheelchairs are not designed to be used as car
seats and cannot provide the same level of
safety as a regular seat in a car, no matter how
well the wheelchair is fastened in the respective
vehicle. DIETZ therefore recommends to seat
wheelchair users on regular vehicle seats when-
ever possible.
The TOMTAR MR-S/MR-LG wheelchair complies
with ISO 7176-19 and is therefore suitable for
use as a seat for transporting passengers in mo-
tor vehicles. It accordingly is labelled in line with
ISO7176-19.
Tests were conducted using a H3 50% dummy
(78 kg) and a headrest.
Passenger cars designed for transporting wheel-
chair users while seated in a wheelchair have to
have a wheelchair space in accordance with the
German Road Traffic Licensing Regulation (St-
VZO). All wheelchair spaces in a vehicle have to
be provided with a wheelchair and wheelchair
occupant restraint system capable of restraining
the wheelchair and its occupant. The vehicle
owner and driver must provide in-car restraint
systems that comply with the ISO 10542 stan-
dard and ensure that they are used correctly.
ISO 7176-19
Crash-tested label
WARNING
Failure to obverse these instructions can result
in severe bodily injury and danger to life!
WARNING
Always ask the carrier whether the respective
vehicle is designed, insured and equipped to
carry a person in a wheelchair..

4 USING THE WHEELCHAIR
P Remove any components that can easily
come free from the wheelchair, such as a
therapy tray or walking aids etc., before
beginning the journey. Keep them in a
suitable safe place.
P Swivelling/adjustable-height leg rests
must not be raised when the user is
being transported whilst seated in the
wheelchair and the wheelchair is secured
by a restraint system and safety belt.
P Adjustable backrests must be put in the
upright position.
P The wheelchair user’s safety during
transport depends on the care with
which the restraint system has been
secured. The person having secured the
restraint system must be trained or
instructed in the use of the system.
Wheelchairs that have been involved in an acci-
dent must be checked by a DIETZ service techni-
cian before any further use.
4 USING THE WHEELCHAIR
Wheelchair user restraint system
First attach the wheelchair restraint system. Next,
the wheelchair user is secured using a suitable
restraint system in line with ISO 10542.
When doing so, the following must always be
ensured:
P Fasten the shoulder and lap belt. Both of
these belts must be fastened quite
tightly, but not so tight as to cause
discomfort to the wheelchair user and
must not be twisted.
P The upper part of the safety belt must
run across the torso and shoulder/
collarbone.
P The lap belt must run at an angle of 30°
to max. 75° from the horizontal but
under no circumstances greater than 75°
(fig. C).
P Safety belts must not be routed over
components of the wheelchair, such as
armrests or wheels, which would hold it
away from the body. (fig. D).
P Only products that are certified in line
with ISO 7176-19/ISO 10542 or DIN
standard 75078 and appropriately
identified by their manufacturer may be
used as restraint systems.
P The wheelchair’s parking brakes must be
fully engaged throughout the drive.
