Safety Summary
Safety Summary
Use
Wheelchairs are exclusively for children and adults who are
unable to walk or have limited mobility, for their own personal
use, when self-propelling and being moved by a third party
(pushed by an attendant), within the home and outdoors.
The maximum weight limit (includes the user and any weight
of accessories fitted to the chair) is marked on the serial
number label, which is affixed to the camber axle or the under-
seat brace bar.
Warranty can only be considered if the product is used under
the specified conditions and for the intended purposes. The
intended lifetime of the wheelchair is 5 years.
Please do not use or fit any third-party components to the
wheelchair unless they are officially approved by Sunrise
Medical.
Area of Application
The variety of fitting variants as well as the modular design
mean that it can be used by those who cannot walk or have
limited mobility e.g. due to:
• Paralysis
• Loss of extremity (leg amputation)
• Extremity defect deformity
• Joint contractures / joint injuries
• Illnesses such as heart and circulation deficiencies,
disturbance of equilibrium or cachexia as well as for
elderly people who still have the strength in the upper
body.
When considering provision, please also note the body size,
weight, physical and psychology constitution, the age of the
person, living conditions and environment.
Final Selection of the type of wheelchair to be used by an
individual rests solely with the user and their health care
professional capable of making such a selection.
General safety
The engineering and construction of this wheelchair has
been designed to provide maximum safety. International
safety standards currently in force have been fulfilled where
appropriate. Nevertheless, users may put themselves at risk
by improperly using their wheelchairs. For your own safety,
the following rules must be strictly observed.
Unprofessional or erroneous changes or adjustments
increase the risk of accident. As a wheelchair user, you are
also part of the daily traffic on streets and pavements, just
like anyone else. We would like to remind you that you are
therefore also subject to any and all traffic laws.
Be careful during your first use in your new wheelchair and
get comfortable and confident before attempting outdoors
or difficult obstacles. It is possible that potholes or uneven
ground could cause this wheelchair to tip over, especially
when riding uphill or downhill. When riding forwards over a
step or up an incline, the body should be leaning forward.
Before each use, the following should be checked:
• Quick release axles on the rear wheels
• Hook and loop patches on seats and backrests
• Tires and tire pressure
• Wheel locks
Before changing any of the adjustments of the wheelchair,
it is important to read the corresponding section of the user
manual.
WARNING:
CHOKING HAZARD – This mobility aid uses small parts
which under certain circumstances may present a
choking hazard to young children.
WARNING:
Travelling downhill at higher speeds in your
wheelchair can cause caster flutter. This can lead to
instability and potentially result in personal injury.
DANGER:
NEVER exceed the maximum load of 242 lbs (110kg) for
Octane Sub4 (187 lbs [85kg] if used with a handbike)
for driver plus any items carried on the wheelchair.
Please note the weight information for lighter weight
options, which are quoted separately. If you exceed the
maximum load, this can lead to damage to the chair,
or you may fall or tip over, lose control and may lead to
serious injury of the user and other people.

Octane Sub4 User Manual | Safety Summary
• If and whenever possible, during a journey in a specially
fitted vehicle for disabled people, vehicle occupants
should use the seats in the vehicle and the appropriate
restraint system. This is the only way to ensure that
occupants will have the maximum protection if there is
an accident.
• To avoid falls and dangerous situations, you should first
practice using your new wheelchair on level ground
with good visibility.
• This wheelchair should be used exclusively to convey
one person at a time. Any other use does not comply
with the intended purpose.
• When getting on or off the wheelchair, do not use the
footplates. These should be flipped up beforehand and
swung to the outside as far as possible. (If applicable)
• Depending on the diameter and setting of the casters,
as well as the center of gravity setting of the wheelchair,
the casters may begin to flutter at high speeds. This can
lead to the casters being blocked and the wheelchair
may tip over.
• In particular, do not travel on an incline without wheel
locks, travel at a reduced speed. Riding sideways on
to a slope or incline, increases the possibility of the
wheelchair tipping over sideways.
• Explore the effects of changing the center of gravity on
the behavior of the wheelchair, for example on inclines,
slopes, all gradients or when overcoming obstacles. Do
this with the secure aid of a helper.
• We recommend that novice users use anti-tip tubes.
Safety Summary Continued
Make sure the casters are pointing in the rearward position
whenever you lean forward. This can be achieved by
advancing the chair and then reversing it in a straight line.
See Fig 1.
Fig 1.
Casters Pointing Rearward
Stability and Balance
To assure stability and correct operation of your wheelchair,
you must at all times maintain balance. Your wheelchair has
been designed to remain upright and stable during normal
daily activities as long as you do not move beyond the
center of gravity. All activities which involve movement in
the chair have an effect on the center of gravity.
Weight Training
Sunrise Medical DOES NOT recommend the use of its
wheelchairs as a weight training apparatus. This product
has NOT been designed or tested as a seat for any kind of
weight training. If occupant uses said wheelchair as a weight
training apparatus, Sunrise Medical shall NOT be liable for
personal injury or equipment damage and the warranty will
be voided immediately.
WARNING:
Any products left in extreme hot or cold climates
could result in hot/cold surfaces which could result in
personal injury.
This product has moving parts and therefore could
trap the user’s fingers. Use extreme caution when
moving.
Do not expose the product or any of its accessories to
any form of excessive heat or naked flame, Including
cigarettes. Tire pressure
DO NOT use your wheelchair unless it has the proper
tire pressure (P.S.I).
DO NOT over inflate the tires. Failure to follow these
suggestions may cause the tire to explode and cause
bodily harm.
WARNING:
WARNING:
The position of the footrest, camber tube and rear
seat height, as well as the tautness of the back
upholstery are directly related to the chair’s stability.
Any change to one or any combination of the three
may cause the chair to decrease in stability. Use
EXTREME caution when using a new seating position
for the first time.

Octane Sub4 User Manual | Safety Summary
Safety Summary Continued
• The wheel locks are not intended to brake your
wheelchair. They are only there to ensure that your
wheelchair does not begin rolling unintentionally. When
you stop on uneven ground, you should always use the
wheel locks to prevent such rolling. Always apply both
wheel locks; otherwise, your wheelchair could tip over.
• The wheel locks have not been designed to be used as
brakes for a moving wheelchair.
• Always make use of elevators and ramps. If these are not
available, you should request the help of an attendant.
They should only grip the wheelchair at securely
mounted parts. If anti-tip tubes are fitted these must be
folded away. A wheelchair should never be lifted with an
occupant; it should only be pushed.
• If the seat and back sling are damaged, you must replace
them immediately.
• Do not lift or carry the wheelchair by the back tubes or
the push handles.
• Be careful with fire, in particular with burning cigarettes.
Seat and back slings can be set alight.
• Always make sure that the quick-release axles on the rear
wheels are set properly and are locked in place. If the
button on the quick-release axle is not pressed in, the
rear wheel cannot be removed.
• In particular when using lightweight metal handrims,
fingers will easily become hot when braking from a high
speed or on long inclines.
• If the wheelchair is subject to direct sunlight for a long
period of time, then parts of the wheelchair (e.g. frame,
leg rests, brakes and side guards) may become hot
(>106°F [>41°C]).
• To avoid hand injuries do not grab in between the spokes
or between the rear wheel and wheel lock when driving
the wheelchair.
• Do not use the wheelchair on slopes > 6°.
• The dynamic safe slope is dependent on the chair
configuration, the user’s abilities and the style of riding.
As the user’s abilities and style of riding cannot be
pre-determined then the max safe slope cannot be
determined. Therefore, this must be determined by
the user with the assistance of an attendant to prevent
tipping. It is strongly recommended that inexperienced
users have anti-tips fitted.
• Do not use your wheelchair on muddy or icy ground.
• Do not use your wheelchair where pedestrians are not
allowed.
• The wheelchair should be used with caution in heavy
rain, snow, slippery, or unsound surfaces.
• Do not use the wheelchair in hazardous environments.
• Anti-tip tubes should prevent the chair tipping over
backwards unintentionally. Under no circumstances
should they take the place of transit wheels, and be
used to transport a person in a wheelchair with the rear
wheels removed.
• With extreme settings (e.g. rear wheels in the most
forward position) and less than perfect posture, the
wheelchair may tip over even on a level surface.
• Do not hang heavy items such as shopping bags or
backpacks, on the push handles, headrest or backrest
of the wheelchair. These can change the tipping point
and there is a risk of tipping backwards.
• When reaching for objects which are in front of, to
the side or behind the wheelchair, make sure that you
do not lean too far out of the wheelchair. If you do it
can change the center of gravity and there is a risk of
tipping or rolling over.
• Only use your wheelchair properly. For example, avoid
travelling against an obstacle without braking (step,
curb edge) or dropping down gaps, or using escalators.
• Only attempt stairs with the help of an attendant. There
is equipment available to help you, e.g. climbing ramps
or lifts, please use them. If there is no such equipment
available, then the wheelchair must be tipped and
pushed over the steps (2 helpers).
• In general, any anti-tip tubes fitted must be set
beforehand, so that they cannot touch the steps, as
otherwise this could lead to a serious fall. Afterwards
the anti-tip tubes must be set back to their correct
position.
• Make sure that the attendant only holds the wheelchair
using securely mounted parts (e.g. not on the footrests
or the side guards).
• When using the lifting ramp make sure that the anti-tip
tubes fitted are positioned outside the danger area.
• Secure your wheelchair on uneven ground or when
transferring (e.g. into a car) by using the wheel locks.
• The wheel locks will only work if there is sufficient tire
pressure and if the correct setting has been made (see
the Chapter on“Wheel locks”).
• When it is dark, please wear light clothing or clothing
with reflectors, so that you can be seen more easily.
Make sure that the reflectors on the side and back
of the wheelchair are clearly visible. We would also
recommend that you fit an active light.
• Adjustments to your wheelchair, especially to security-
relevant components as for example wheel-locks,
anti-tip or backrest must be performed by authorized
dealers.
• It is recommended to clean and disinfect the entire
product, especially the upholstery, frequently.
• Do not tilt the wheelchair without assistance.
• Do not reuse single use fasteners.

WARNING:
Changing the size of your rear wheels can seriously
affect the performance and stability of the wheelchair.
Procedure 2 - Rear Wheels
Procedure 2
Fig 18.
The rear wheels are quick release and are designed to be
removed and attached frequently. All rear wheels use
quick release axle pins to secure the wheels to the frame,
although these vary in length, they operate the same.
2.1: Removing/attaching rear wheels
Push the quick release button and pull the wheel
outwards. To install, push and hold the button and insert
the quick release axle pin into the axle until the pin clicks
into position. Ensure both wheels are fully engaged prior
to use.
2.2: Adjusting Quick release axle pin
Only adjust the quick release axle pin if the wheel does
not engage or the wheels feel loose. To adjust the length,
remove the axle pin from the wheel and by using 2 x
adjustable spanners/wrenches as per Figure 19, extend or
shorten the pin as required.
Fig 19.
A = Lengthen B = Shorten
WARNING:
Any adjustments to your quick release pins – then YOU
must ensure your wheels lock on both sides of your
wheelchair.
When attaching the rear wheels, always check that they
are securely mounted. Pull on the rear wheels to make
sure the detent pin / RGK cap of the quick release axle
are fully released before operating the wheelchair.
You should NOT be able to pull the rear wheel off.

Procedure 3 - Tires and Inner Tubes
Procedure 3 & 4
Tires will wear just like a car tire and the time will depend on the type of use. It is recommended that both tires are
changed once the tread fades. For pneumatic tires, there is a risk that a puncture will occur and the inner tube will need
to be replaced in order to keep the wheelchair operational.
3.1: Changing the tire
Remove the wheel from the wheelchair and release air in the
tube by pressing the small pin inside the valve. If a Presta
valve, then unscrew both the head and the securing ring at
base and press the top until air releases. Using 2 x tire levers
(supplied in the toolkit), unhook the tire completely from
the wheel rim. Remove inner tube and tire from wheel rim.
To install the tire, place one side of the new tire on the
wheel rim. Then insert the inner tube inside the tire and
align the valve with the wheel rim hole. Ensure there are
no kinks or uneven tension in the inner tube before putting
the second side of the tire back on the wheel rim using the
tire levers. Be careful not to pinch the inner tube. Once tire
and inner tube are on the wheel rim, replace securing ring
(if applicable) then inflate tire a little. Adjust inner tube and
tire so that they fit nicely on the wheel rim and inflate to the
recommended tire pressure.
3.2: Changing the inner tube
Repeat the method above but do not remove tire
completely, just remove inner tube. If problems continue,
remove tire and inner tube and ensure there are no sharp
edges in the wheel rim which may be causing a puncture.
4.1: Adjusting Axle Tube position
To adjust the axle position, remove wheels. Using a 5mm allen
key from the toolkit, release the top screw on each side of
the axle clamp as shown in Fig 21 (A). Once released but still
intact, move the axle backward for more stability and move
forward for more tip. Tighten the top screws once position has
been set, and carefully use the chair as if it were the first time.
4.2: Replacing Axle tube
To replace the axle tube, remove wheels. Using a 5mm allen
key from the toolkit, release the bottom screw completely from
the axle clamp as shown in Fig 21 (B). Take note of the distance
between the axle clamp and the axle tube for set up of the
new axle tube. Slide new tube into the clamps and into the
same position as the old axle tube. The notch in the axle insert
must be at the top of the axle tube.
If the wheelchair feels slow after replacing the axle tube, rotate
the axle tube a little forwards or backwards to correct the
wheel alignment.
WARNING:
The position of the footrest, camber bar, as well as
the tautness of the back upholstery, are directly
related to the chair’s stability.
Any change to one or any combination of the
three may cause the chair to decrease in stability.
Use EXTREME caution when using a new seating
position for the first time.
A = Adjust Position
B = Remove and replace
Procedure 4 - Camber Bar
The Camber Axle or Camber Tube control your wheel position and your center of gravity. It is very important to have this
set up for your requirements for performance and safety. Axle tube can be fixed or adjustable. Fixed means this cannot
be adjusted and for a user who is experienced and knows their balance point. Adjustable position gives the user choice
and is ideal for less experienced users

Procedure 6 - Wheel Locks
WARNING:
After any adjustments, repair or service and before use, make sure all attaching hardware is tightened securely –
otherwise injury or damage may result. If wheel locks do not hold occupied wheelchair in place please adjust as above,
or contact your dealer – otherwise injury or damages may occur. The wheel locks are designed to work when your
wheelchair is static. Wheel locks should not be applied during use and tire pressure should be as indicated on the tire.
Before adjusting or replacing any style of wheel lock ensure that the tires are
inflated to the recommended pressure as indicated on the tire.
NOTE:
The wheel locks are adjustable in position to suit tire changes and wear. As tires
wear, the wheel lock may not hold the wheelchair as intended, so these need to be
adjusted to suit the tire condition.
6.1: Adjusting Wheel locks
Using a 5mm Allen key from the toolkit, release the 2 screws in the clamp or on the
underside of the plate. Once the wheel lock is loose, reposition so that there is at
least 3mm of interference when the wheel lock is activated. Tighten securely and
repeat on the other side.
Procedure 5 - Caster Wheels and Forks
Caster Bearings must be fitted by an authorized dealer.
Failure to do so will result in invalid warranty on the parts.
NOTE:
CAUTION:
DO NOT replace the front caster forks or
caster wheels with a different size other than
what was originally supplied on the chair.
Changing to a different size caster fork or
caster wheel will have an adverse effect on
the running of the chair and the end user’s
balance causing personal injury.
The caster wheels at the front of the wheelchair will wear just like car tires and should be replaced when they visibly look
worn or cracks appear.
5.1: Changing caster wheels
Using 2 x 4mm allen keys from the toolkit, remove 1 of the 2 screws
in the center of the caster wheel, as shown in Fig 22. Remove
the screw and slide out the caster axle with the other screw still
attached, noting any spacers and their positions. Install the new
caster wheel and slide the caster axle back through and secure with
the final screw.
5.1: Changing caster Fork
Remove the bolt at the back of the caster housing using a 4mm
Allen key from the toolkit. Then use the special spanner to undo the
caster fork assembly as pictured in Fig 22, while holding the frame.
The entire caster assembly will unscrew giving you access to the
bearings and caster fork. Use the socket to release the nut which
will release the fork. When installing, screw in the housing as far as it
can go and line up the hole so the securing bolt can be tightened.
