2.7 Safety information on wheelchairs with a
lifter
WARNING!
Risk of injury by moving parts
– Never let objects get caught in the space underneath a
raised lifter.
– Make sure that neither you nor anyone else is injured
by placing hands, feet other body extremities under
the raised seat.
– Should you not be able to view under the seat, for
example, due to limited manoeuvrability, turn the
wheelchair once on its own axel before you lower the
seat. This will allow you to make sure that nobody is
located in the danger zone.
18
CAUTION!
Risk of injury if the wheelchair tips over
– Never exceed the maximum permissible load (see
chapter 11 Technical data, page102).
– Avoid dangerous driving situations when the lifter is in
a raised position, such as trying to overcome obstacles
like kerbs or driving up or down steep gradients.
– Never lean out of the seat when the lifter is raised.
– Inspect the lifter module at least once a month to
make sure the automatic speed reduction function,
which reduces the speed of the wheelchair when the
lifter is raised, is working properly (see chapter 3.3
The Lifter, page 23). Notify your authorised dealership
immediately if it is not working properly.
CAUTION!
Risk of malfunction of the lifter module
– Inspect the lifter module at regular intervals to make
sure there are no foreign objects or visible damage,
and to make sure the electric plugs are firmly inserted

components. At operating temperatures below
freezing point this can, in particular, lead to the lifter
actuator being shut down after approx. 1 second
operating time.
– The lifter can be raised or lowered gradually by
repeatedly operating the joystick. In many cases this
generates sufficient heat for the actuator to operate
as normal.
23
Invacare® Storm®⁴ Series
NOTE - speed limiter
– The lifter is fitted with sensors which reduce the
mobility device speed as soon as the lifter is raised
above a certain point.
– This takes place to guarantee the tipping stability of the
mobility device and to avoid damage to the legrests.
– If the speed limit is activated, a corresponding blink
code is displayed on the remote or a reduced drive
level is set automatically. Please refer to the remote
manual for more information.
– To reapply normal speed, run the lifter down until the
status display stops blinking.
CAUTION!
Risk of tipping, if the speed limiter sensors fail
when the lifter is raised
– If you find that the speed reduction function is not
working when the lifter is raised, do not drive with
the lifter raised and immediately contact an authorized
Invacare dealer.

Accessories
4 Accessories
Belt with metal buckle, adjustable both sides
4.1 Postural belts
A postural belt is an option which can either be fixed to the mobility
device ex-works or can be retrofitted by your specialist dealer. If
your mobility device is fitted with a postural belt, your specialist
dealer will have informed you about fitting and usage.
The postural belt is used to help the mobility device user keep an
optimum sitting position. Correct use of the belt assists the user
in sitting securely, comfortably and well-positioned in the mobility
device, especially for such users who do not have such a good sense
of balance while sitting.
We recommend using the postural belt whenever the
mobility device is used. The belt should be tight enough to
ensure that you are sitting comfortably and that your body is
in the correct sitting position.
4.1.1 Types of postural belts
Your mobility device can be fitted with the following postural belt
types ex-works. If your mobility device has been fitted with a different
belt to those listed below, please ensure that you have received the
manufacturer's documentation with regard to correct fitting and use.
Belt with metal buckle, adjustable one side
Belt can be adjusted on both sides. This means that the buckle can be
centrally positioned.
4.1.2 Adjusting the postural belt correctly
1.
2.
3.
4.
5.
Ensure that you are sitting correctly, which means that you are
sitting right at the back of the seat, your pelvis is positioned erect
and as symmetrically as possible, not to the front, to the side or
at one edge of the seat.
Position the postural belt so that your hipbones can be easily
felt above the belt.
Adjust the belt length using one of the adjustment aids described
above. The belt should be adjusted so that you can fit a flat hand
between the belt and your body.
The buckle should be positioned as centrally as possible. In doing
so, carry out adjustments on both sides as much as possible.
Check your belt every week to ensure that it is still in good
working condition, to ensure it has no damage or wear, and
that it is fixed properly to the mobility device. If the belt
is only fastened with a bolted connection, ensure that the
connection has not loosened or come undone. You can find
more information about maintenance work on belts in the
service manual, which is available from Invacare.
4.2 Using the cane holder
Belt can only be adjusted on one side which can result in the buckle
not sitting centrally.

5.13 Adjusting the suspension and the shock
absorbance
Taking the user weight into account, the Storm®4 suspension and
shock absorbance can be individually adjusted to a softer setting for
more comfort and less shock absorbance or a harder setting for a
harder suspension and more support. These adjustments should
only be carried out by trained specialists. Contact your authorized
Invacare specialist dealer.
Tools:
• 4 mm Allen key
It is easier to adjust the suspension and shock absorbance if
there is no-one sitting in the chair.

5.13.2 Disabling the suspension and shock absorbance
You can disable the suspension and shock absorbance so that they
are no longer working.
1.
•
•
If you set the shock absorbance harder, you get a more direct
response to the ground for more sportive driving with a less
swinging chassis.
The softer you set the shock absorbance, the softer the response
to the ground is and the more comfortable the driving is.
Move the lever A from "Active" ("open lock" symbol, B) to
"Inactive" ("closed lock" symbol, C).

Right
The works setting for the wheel is the middle position. From here,
the shock absorbance can be adjusted to be softer (-) or harder (+)
in 10 levels in either direction.

•
6.1 Driving
The maximum load capacity that is stated in the technical
data only states that the system is designed for this mass
in total. However, this does not mean that one can sit
a person with this body weight in the mobility device
without restrictions. Attention must be paid to the body
proportions, such as height, weight distribution, abdominal
belt, leg and calf strap and seat depth. These factors have
a strong influence on driving features such as tilt stability
and traction. The permissible axle loads in particular must
be adhered to (refer to 11 Technical data, page102). It may
possibly be necessary to carry out adaptations to the seat
system.
6.2 Before driving for the first time
The rear mirror (if installed) is adjusted so you can look behind
at all times without having to bend forward or shift your seating
position.
6.3 Parking and stationary
When parking your vehicle or if your vehicle is stationary for a
prolonged period:
1.
2.
Switch the vehicle's power system off (ON-/OFF key).
Activate your anti-theft lock, if existing.
6.4 Getting in and out of the mobility device
– The armrest must be removed or swiveled up in order
to get into or out of the mobility device from the side.
6.4.1 Removing the standard armrest in order to
side transfer
Before you take your first trip, you should familiarize yourself well
with the operation of the mobility device and with all operating
elements. Take your time to test all functions and driving modes.
If installed, make sure to properly adjust and use the postural
belt each time you use the mobility device.
Sitting comfortably = Driving safely
Before each trip, make sure that:
•

6.6 Driving up and down gradients
75
Invacare® Storm®⁴ Series
CAUTION!
Risk of tipping over
– Only ever drive downhill at a maximum of 2/3 of the
top speed. Avoid sudden changes of direction or
abrupt braking when driving on slopes.
– Always return the backrest of your seat or the seat tilt
(if adjustable seat tilt is available) to an upright position
before ascending slopes. We recommend that you
position the seat backrest or the seat tilt slightly to
the rear before descending slopes.
– Always lower the lifter (if fitted) to its lowest position
before ascending or descending a slope.
– Never attempt to ascend or descend a slope on
slippery surfaces or where there is a risk of skidding
(such as wet pavement, ice etc).
– Avoid trying to get out of the vehicle on an incline
or a gradient.
– Always drive straight in the direction the road or path
you are on goes, rather than attempting to zigzag.
– Never attempt to turn around on an incline or a slope.
CAUTION!
Braking distance is much longer on a downhill
slope than on even terrain
– Never drive down a slope that exceeds the maximum
safe slope (refer to 11 Technical data, page102).
76
Important information about regulating the
actuator functions on gradients
– Your mobility device is fitted with an angular sensor
which guarantees tipping stability. The sensor
measures the actual angle of the drive unit, and
prevents any further decrease in stability by restricting
the functionality of the adjustment actuators. If this
safety function is activated, the backrest and the seat
tilting can only be moved forwards, and the lifter can
only be lowered. Reposition your mobility device
on level ground so that the actuators can function
normally again.
6.7 Using foldable antitippers
Where space is restricted, e.g. in an elevator or when being
transported in a car, the mobility device may be too long. Foldable
antitippers can be useful here. These can only be operated by an
attendant as they are positioned beyond the reach of the user.
CAUTION!
Risk of tipping if the antitippers are not returned
to the driving position before moving off
– Always return the antitippers to the driving position
before moving off (see the figure below).
– Make sure that the locking pin is fully engaged.

7 Electrical system
In the following, you find information on how to charge, handle,
transport, store, maintain, and use batteries.
7.1 Electronics protection system
7.2.1 General information on charging
The vehicle drive electronics is fitted with an overload protection.
New batteries should always be fully charged once before their first
use. New batteries will be at their full capacity after having run
through approx. 10 - 20 charging cycles (break-in period). This
break-in period is necessary to fully activate the battery for maximum
performance and longevity. Thus, range and running time of your
mobility device could initially increase with use.
If the drive is severely overloaded over a long period (for example,
during steep climbs) and, above all, at simultaneous high external
temperatures, the electronic system can overheat. In this case,
the vehicle performance is gradually reduced until it comes to a
standstill. The status display shows a corresponding flash code (please
refer to the user manual for your remote). If you switch the drive
electronics off and then on again, the error message is deleted and
the electronics can be switched on again. It can however take up to
five minutes until the electronics has cooled down enough for the
drives to apply their full performance.
If the drive is blocked due to an insurmountable obstacle, for
example, a curb or similar which is too high, and the driver attempts
to run the drive for more than 20 seconds against this obstacle, the
electronic system switches the drives off to avoid damage. The status
display shows a corresponding flash code (please refer to the user
manual for your remote). If you switch the drive electronics off and
then on again, the error message is deleted and the electronics can
be switched on again.
A defective main fuse may be replaced only after checking
the entire electric system. An specialized Invacare dealer
must perform the replacement. You can find information on
the fuse type in 11 Technical data, page102.
Gel/AGM lead acid batteries do not have a memory effect as NiCd
batteries.
7.2.2 General instructions on charging
Follow the instructions listed below to ensure safe use and longevity
of the batteries:

7.2 Batteries
Power is supplied by two 12 V batteries. The batteries are
maintenance-free and only need regular charging.
80
Charge 18 hours prior to initial usage.
We recommend charging the batteries daily after every
discharge even after partly discharge, as well as each night over
night. Depending on the level of discharge, it can take up to 12
hours until the batteries are fully charged again.
When the battery indicator reached the red LED range, charge
the batteries for 16 hours minimum, neglecting the charge
complete display!
Try to provide a 24 hour charge once a week to make sure that
both batteries are fully charged.
Do not cycle your batteries at a low state of charge without
regularly recharging them fully.
Do not charge your batteries under extreme temperatures.
High temperatures above 30 °C are not recommended for
charging as well as low temperatures below 10 °C.

are supplied by Invacare comply with these requirements.
You cannot overcharge the batteries when using the charger
supplied with your mobility device, or a charger that has been
approved by Invacare.
Protect your charger from sources of heat such as heaters
and direct sunlight. If the battery charger overheats, charging
current will be reduced and the charging process delayed.
WARNING!
Risk of electric shock and damage to the batteries
– NEVER attempt to recharge the batteries by attaching
cables directly to the battery terminals.
WARNING!
Risk of fire and electric shock if a damaged
extension cable is used
– Only ever use an extension cable if it is absolutely
necessary. In case you must use one, make sure it
is in good condition.
7.2.3 How to charge the batteries

7.2.5 Storage and Maintenance
Follow the instructions listed below to ensure safe use and longevity
of the batteries:
81
Invacare® Storm®⁴ Series
•
•
•
•
•
Always store the batteries fully charged.
Do not leave the batteries in a low state of charge for an
extended length of time. Charge a discharged battery as soon
as possible.
In case your mobility device is not used for a longer period
of time (that is more than two weeks), the batteries must be
charged at least once a month to maintain a full charge and
always be charged before use.
Avoid hot and cold extremes when storing. We recommend to
store batteries at a temperature of 15 °C.
Gel and AGM batteries are maintenance-free. Any performance
issues should be handled by a properly trained mobility device
technician.
7.2.6 Instructions on using the batteries
•
•
•
•
•
CAUTION!
Risk of damaging the batteries.
– Avoid ultra-deep discharges and never drain your
batteries completely.
•
•
•
82
Pay attention to the Battery Charge Indicator! Charge the
batteries when the Battery Charge Indicator shows that battery
charge is low.
How fast the batteries discharge depends on many
circumstances, such as ambient temperature, condition of the
surface of the road, tire pressure, weight of the driver, way of
driving and utilisation of lighting, if fitted.
Try to charge the batteries always before you reach the red LED
range.
The last 3 LED (two red and one orange) mean a remaining
capacity of about 15 %.
Driving with flashing red LED’s means an extreme stress for the
battery and should be avoided under normal circumstances.
When only one red LED is flashing, the Battery Safe feature
is enabled. From this time, speed and acceleration is reduced
drastically. It will allow you to move the mobility device slowly
out of a dangerous situation before the electronic finally cuts off.
This is deep discharging and should be avoided.
Be aware that for temperatures below 20 °C, the nominal
battery capacity starts to decline. For example, at -10 °C
the capacity is reduced to about 50 % of the nominal battery
capacity.
To avoid damaging the batteries, never allow them to be fully
discharged. Do not drive on heavily discharged batteries if it is
not absolutely necessary, as this will strain the batteries unduly
and shorten their life expectancy.
The earlier you recharge the batteries, the longer they live.
The depth of discharge affects the cycle life. The harder a
battery has to work, the shorter is its life expectancy.
Examples:
– One deep discharge stresses the same as 6 normal cycles
(green /orange display off).
– The battery life is about 300 cycles at 80 % discharge (first 7
LED off), or about 3000 cycles at 10 % discharge (one LED
off).
The number of LED can vary depending on the
remote type.
•
Under normal operation, once a month the battery should be
discharged until all green and orange LED are off. This should be
done within one day. A 16 hour charge afterwards is necessary
as reconditioning.
7.2.7 Transporting batteries
The batteries supplied with your mobility device are not hazardous
goods. This classification is based on the German GGVS Hazardous
Goods Road Transport Ordinances, and the IATA/DGR Hazardous
1529686-R
Electrical system
Goods Rail Transport / Air Transport Ordinances. Batteries may be
transported without restrictions, whether by road, rail or by air.
Individual transport companies have, however, guidelines which can
possibly restrict or forbid certain transport procedures. Please ask
the transport company regarding each individual case.
7.2.8 General instructions on handling the batteries
• Never mix and match different battery manufactures or
