Netti 4u Base without cushions, 16” wheels
1. iNtroDuctioN
Netti 4U Base is a wheelchair chassis meant to function as a base for external seating systems and modular seats, as well as for the Netti Seating System.
Netti 4u Base with Netti seating system has been tested to DiN eN 12183:2014. the tests were carried out by tÜV sÜD Product service GmbH in Germany.
in alu rehab we believe that wheelchairs should be chosen based on a thorough assessment focusing on the needs of the user and demands from the environment. therefore it is important to know about the possibilities and restrictions of the wheelchair. the wheelchair is constructed for indoor and outdoor use, and offers the possibility to vary the sitting position from activity to rest using tilt and recline functions.
Max user weight: 135 kg.
When mounting accessories such as
power kit, external seating systems etc.,
the weight of the accessories must be
subtracted from the max user weight.
Specifications varies between
countries.

7.1 SeAt ANGLe
the seat angle is regulated using the release handle mounted on the push bar.
the seat unit can be tilted from -5° to +20°.
tilt and recline are the basic benefits of a comfort wheelchair. it allows for varying seating positions during the time in the wheelchair.
We have reviewed the clinical evidences regarding tilt and recline, and found there are several studies or best practice guidelines suggesting that the tilt and recline sequence is important to reduce shear and sliding: firSt tiLt theN recLiNe AfterWArdS.
If you adjust the seat tilt below 0°, there is an increased risk of slipping forward out of the chair. Alu Rehab recommends the use of a hip belt to prevent falling out of the chair.
When bringing the client upright again, the sequence should be recline first then tilt. it would seem that the most shear would be induced when going upright from a recline and tilted position.
7.2 BAcKreSt ANGLe
the backrest angle is regulated using the release handle mounted on the push bar. the angle can be regulated from 90° forward to
45° backwards.
to ensure correct function of the
wires, these must never be taut. the seat and back-rest angle must not
be adjusted without using the anti-tips. the release handles has each on of the following label:
7.4 decreASe the poSSiBiLity of SLidiNG, SheAr ANd preSSUre SoreS:
only use the tilt angle to achieve variation of the seating position for the user. it is common knowledge that recline should not be adjusted after the back angle is accommodated to the user’s best seating position. the muscle tone of the neck and back should be as low as possible for the user to prevent sliding, and a change of the recline angle from the original position will interrupt and destroy the correct body position, and cause an increased muscle tone in the neck. tilt recline risk for tipping.
check the position of anti-tip.
When chair back extension is mounted, the tipping risk increases. if necessary it should be improved by moving the main wheels further back. Always use anti-tippers when recline and tilt functions are being activated.
Model: Netti 4u BASE
Language: English Version: if the recline function is used during a transfer situation or other situations, it is very important that the recline angle is adjusted back to the correct, original position when the user is back to a normal seating position.
Wrong usage of recline causes an increased possibility of sliding, and this means an increased danger of shear (vertical and hori zontal forces) and pressure sores.

8.1 GeNerAL techNiQUeS
Manoeuvering and chair balance: the weight and balance of the chair influences the maneuvering qualities of the wheelchair. the weight, size and sitting position of the user are influencing factors. the position of the wheels will in addition influence the manoeuvering qualities. the more weight placed over the main wheels, the
.
easier it is to manoeuver. if heavy weight is placed over the front castors, the chair will be heavy to manoeuver. see page 16 - seat depth adjustment - for balancing the chair.
8.2 driViNG techNiQUeS
- step up-
companions, drive up a step forwards:
• Check that the anti-tip is turned up.
• Angle the wheelchair backwards.
• Balance the chair on the mainwheels and
push it forward until the front castors are
on the step.
• Lift the push handles while pushing the
chair onto the step.
turn the anti-tip downwards.
Step approach: always approach the step in slow motion preventing the front castors to hit the step with force. the user could fall out of the chair by the impact. the front castors could be damaged.
Users, drive up a step backwards: this technique is only useful if the step is very low. it also depends on the clearance between the foot plates and the ground.
• Check that the anti-tip is turned up.
• Drive the chair backwards towards the
step.
• Make a firm grip on the push rims and
move the body forward while pulling.
turn the anti-tip downwards.
driving down steps / sidewalks
Be cautious that you do not drive down steps higher than 30 mm. the leg supports may hit the ground first. thereby you may lose steering control and the leg supports may brake. driving on soft, rough or slippery ground can make safe manoeuvring more difficult as the wheels may loose traction and it is difficult to control the wheelchair.
companions, drive up a step backwards:
• Check that the anti-tip is turned up
• Pull the chair backwards next to the
step
• Angle the wheelchair backwards,
moving the front castors slightly up in
the air.
• Pull the wheelchair up the step and go
backwards long enough to put down the
front castors on the step.
turn the anti-tip downwards parking: increase the footprint and the support of the wheelchair by moving the chair about 100 mm rearwards making the front castors turn forward.
companion: if the user is left alone in the wheelchair, always lock the brakes and check that the anti- tips are turned down.

Always ask for assistance.
Never use escalators, even if assisted

With assistance, backwards.
• Check that the anti tip is turned up,
• Pull the wheelchair backwards to the first
step of the stairs.
• Angle the wheelchair backwards on the
main wheels.
• Pull the wheelchair slowly up the stair,
one step at the time keeping the balance
on the main wheel.
• Reaching the top of the stair, pull the
wheelchair backwards far enough to put
the front castors safely down on the
floor.
turn the anti tip downwards.
if two companions are present, one
person can assist lifting in the front
of the frame.
do not lift the wheelchair holding

do not lift the wheelchair holding

the companions should use the
strength in their legs carrying the
chair, avoiding unnecessary stress
on the back.
driving uphill:
Move the upper part of the body forwards in order to maintain the balance of the chair driving downhill:
Move the upper part of the body backwards to maintain balance of the chair. control the speed of the chair by clutching the push rims. Do not use the brakes.

the chair is marked with stickers showing where to fix the straps.
in front: use hook or strap attachment.
Alternative push rims may give a better
grip, but the friction may increase.
When using the hands to stop the chair,
the risk for burning of the hands
increases.
A squeezing and trapping hazard of the
fingers may occur when passing
through narrow passages and if the
fingers come between the spokes.
to avoid this risk, we recommend spoke
protectors as accessory.
