CHECK
CHECK BOX
Motors: clean them, check for leakage of lubricant. Check bearings cables
and connectors.
Check that the park brakes on both sides click when the joystick is moved
out of neutral with the park brake lever in the drive position. If they do
not click this is a sign of a serious failure and the chair must not be driven
again until this fault has been corrected.
The motors and gearboxes should not make loud noises or show signs of
burning. If the motors smell of burnt insulation (this is a very strong smell),
they will have been used outside of their normal duty. They will need to
be replaced immediately. Claims for burnt out motors will not be accepted
under warranty unless there are exceptional circumstances.
Check for normal function of the motors by doing a driving test on flat
ground for 2 minutes. If the motors or the park brakes become hot to
touch during such a short time there is probably a serious fault either with
the motors or the park brakes that must be investigated and rectified.
Notes:
Motors and gearboxes are electromechanical components. It is
normal to hear noises from the motors used on Netti Mobile when during
normal operation. The standard we work to allows for up to 65dB(A)
which might sound loud in a quiet environment such as some hospital
wards
In some weather conditions and at very low speeds sometimes used for
moving a chair in tight spaces you might hear an occasional squeaking
sound that goes away as soon as the chair drives at normal speeds. This
is normal for this class of motor it comes from the very small clearance
between to park brake and the motor housing liner.
If you change a motor on one side you might notice the chair then veers to
one side when the joystick is pushed full forward. If this happens the veer
compensation parameter will need to be adjusted. Refer to the control
system manufacturer’s installation manual for the correct procedure.
Veer occurs when there are motors on the chair from different production
batches. In severe cases it may be necessary to change the motors on
both sides even if only one of them is defective.
