Before operating the wheelchair for the first time and regularly thereafter, check that the tire pressure meets the specifications in this manual. Check the tire pressure when the wheelchair experiences a significant change in temperature or altitude. Incorrect tire pressure may cause the wheelchair to be less stable, less maneuverable and cause damage to the wheelchair and/ or bodily injury.

NOTICE Risk of damage if tires are overfilled

Do not overfill the tires. Overfilling may result in damage to the wheel assembly.

NOTICE Risk of reduced performance when tire pressure is

insufficient

Insufficient tire pressure may result in abnormal wear and a shorter driving range.

CAUTION!

Maintenance by a qualified service technician

Only qualified service technicians should perform the maintenance and repair specified in this manual. Read all instructions carefully before proceeding. If any questions arise, contact Permobil for assistance.

• Release the joystick immediately. Both park brakes must be engaged within 2 seconds.

• Repeat the test three times, bringing the joystick slowly backwards, to the left and to the right.

7.2.7.3 Test run

Set the highest permitted speed to the lowest value and run the wheelchair in all directions while checking that it runs smoothly and is easy to maneuver.

Repeat the test with the speed control set to the highest possible value.

7.2.7.4 Gradient test

WARNING!

Prevent tipping during test

When this test is conducted, an additional person must be present in order to prevent the wheelchair tipping over backwards.

Run the wheelchair forwards up its steepest permitted gradient. Release the joystick when the wheelchair is moving up hill; check that the wheelchair stops and that the brakes function as intended without the front wheels lifting from the ground.

Move the joystick forward and continue uphill. Check that the wheelchair moves gently forwards.

Stop the wheelchair then back it downhill. Release the joystick when the wheelchair is moving downhill; check that the wheelchair stops and that the brakes function as intended without the front wheels lifting from the ground.

7.2.7.5 Testing lights, turn signals and warning lights

If the wheelchair is equipped with lights:

• Check that they all light up as intended.

• Check that they all light up as intended and that the flashing frequency is 1.5 Hz ± 0.5 Hz.

• Remove the bulbs in turn and check that the remaining bulb on the same side flashes at a frequency of 3 Hz ± 0.5 Hz.

If the wheelchair is equipped with hazard lights:

• Check that all bulbs light up as they should and that the flashing frequency is 1.5 Hz ± 0.5 Hz.

7.2.7.6 Testing adjustment device

If the wheelchair is equipped with an adjustment device:

• Check that all motors move in the right direction.

• Make sure that the mechanical end stops are secured and that they stop the adjustment device motors, and thus use the automatic end stop tracking that is in the seat and light module (ISM).

7.2.7.7 Testing inhibit signal

Connect a suitable battery charger or equivalent inhibit connecting device in the charging contact on the joystick module and check that the wheelchair is prevented from running.

If inhibit contacts 2, 3, 4 and 5 are used for inhibiting or restricting speed, suitable test must be performed in order to check that they are functioning as intended.

7.3 Diagnostics R-net LED control panel

7.3.1 Battery voltage indicator

Each time the wheelchair is started, parts of its electronics are checked. When a fault occurs in these parts, it is displayed on the control panel battery voltage indicator and the indicator for speed or driving profile in the form of one or more flashing LEDs.

Troubleshooting and repairs must always be performed by qualified personnel with good knowledge of the wheelchair‘s electronics.

NOTICE Error signals

Error messages are not displayed on the indicators while the wheelchair is being driven. They appear when it is next started.

7.3.2 Steady

Everything is in order. The number of LEDs that light up depends on the charge remaining in the batteries. If the batteries are fully charged, all the LEDs light up.

7.3.3 Slowly flashing red LEDs, 1–2 LEDs

The batteries must be charged immediately.

7.3.4 Rapidly flashing, 1–10 LEDs

A fault has been detected in the wheelchair‘s electronics and the wheelchair may not be driven.

1. Switch off the wheelchair.

2. Check that all visible cables and the cable to the control panel are

connected correctly.

3. Switch the wheelchair on again. If the fault persists, count the

number of flashing LEDs and check for a possible cause and remedy in the following table.

4. Do not use the wheelchair until the problem has been remedied or

you have received other information from your service provider.
