2 Safety
All of the very latest information relating to product safety and any product recalls
can be found on our website at www.DIETZ-Power.com.
Warning
Follow the instructions given under warnings! Failure to exercise due care in
following these instructions may result in physical injury, damage to the wheelchair
or damage to the environment.
2.1. Safety guidelines
Warning
• We advise you to contact our service department before you do repairs to a
wheelchair that has been involved in an accident.
• Maintenance and repairs may only be carried out by trained and authorised
service technicians. Temporary employees and persons in training may only
carry out repair and replacement work under the supervision of an authorised
service technician.
• Only do maintenance on an empty chair, without user.
• Always make sure that you work safely, particularly when you need to lift up
the wheelchair.
• DIETZ-Power will deliver a wheelchair with default factory settings. These
settings depend on the options ordered with the wheelchair. When a
conguration is ordered that causes interference, DIETZ-Power applies
modied settings.
• Programming should only be conducted by professionals with in-depth
knowledge of wheelchair control systems. Incorrect programming could result
in an unsafe set-up of the wheelchair for a user. DIETZ-Power accepts no
responsibility for losses of any kind if the programming of the control system is
altered without authorization of DIETZ-Power.
• During the execution of maintenance and repairs, the service technician is at all
times fully responsible for the fullment of locally applicable safety.
• After repairing, reprogramming or replacing parts, always check the
functionality of the entire wheelchair. Pay special attention to safety features
such as slowdown driving or drive inhibits when seat lift and tilt are both used.
2.2. Temperature
Warning
• Avoid any physical contact with the motors of the wheelchair at all times. When
the wheelchair is in use, the motors are in constant motion and can reach high
temperatures. Any physical contact with the motors could result in burns. After
use, the motors cool down slowly.
• Ensure that the wheelchair is not exposed to direct sunlight for long periods of
time when not in use. Some parts of the wheelchair (such as the seat, backrest
and armrests) can become hot if exposed to the sun for too long. This may
result in burns or skin sensitisation.
2 Safety
SANGO ADVANCED / SLIMLINE - 7

2.3. Moving parts
Warning
Wheelchairs contain moving and rotating
parts (gure 1). Contact with moving parts
may result in serious physical injury or
damage to the wheelchair. You should
avoid any contact with the moving parts of
the wheelchair.
A. Powered leg rests
B. Swing-away controller arm
C. Powered backrest adjustment
D. Powered tilt adjustment
E. Powered lift adjustment
F. Wheels (turning and pivoting)
2.4. Electromagnetic radiation
The standard version of your powered wheelchair has been tested for compliance
with the applicable requirements relating to electromagnetic radiation (EMC
requirements).
Warning
Despite testing, the following cannot be ruled out:
• electromagnetic radiation interfering with the wheelchair. For example mobile
telephones, large medical devices or other sources of electromagnetic radiation
• the powered wheelchair interfering with electromagnetic elds. For example
shop doors, burglar alarm systems in shops or garage door openers.
• in some congurations equipped with a R-net controller, where it is possible
that extreme electrical discharge situations due to static electricity, may cause
a fault message (‘ISM over-current’) ashing on the screen. If this occurs simply
turn o your wheelchair for a few seconds and back on to clear the fault.
In the unlikely event of such problems arising, please notify your dealer
immediately.

Warning!
• A crash test with Dahl was performed

kg.
• The Dahl docking station is only allowed to build into a vehicle by trained and
authorized sta of a registered car adaptation company. For ordering the Dahl
docking and its accessories, please contact Dahl Engineering in Denmark for
further details www.dahlengineering.dk.
To mount the Dahl docking station our preparation kit (SPARES 5000062) and
the following Dahl parts are needed:
• 500561 Docking plate (C)
• 502800 High grade steel Torx 27 bolts M8 Quality 14.9 (D)

and the dedicated holes in the chassis
(gure 14).
Warning!
• The Dahl high grade steel Torx bolts
(D) only come in one length which
is often too long. They need to
be cut into the right length by the
authorized engineer to t the locking
plate properly without damaging the
batteries.
• Do not use any other M8 bolt to
replace 502800. They will not be strong
enough. The bolt length must be such
that they are ush with the upper side
of the hexagon nuts (502186). The
thread may neither protrude beyond
the hexagon nuts or be too short to
achieve their full holding force in the
thread.
5. Add Loctite 222 onto the thread of the
high grade Torx bolts to secure them
and tighten them with a torque wrench
to the preset torque of 16-18Nm
6. Position the two plastic spacers (F) in
the battery slide plate.
7. Place the batteries and the battery
slide plate back in the battery box.
