Maintenance
Despite the solid construction and usage of resistant materials, the device is subject to wear. It is therefore
recommended to have a professional checking the device at regular intervals –usually at 2 years since purchase or
earlier if there is any doubt about the device’s performance.
This guideline value of 2 years may vary with the device's respective degree of utilization and the behavior of the user.
Checking the degree of utilization and the user behavior is the responsibility of the operator.
Attention! Please also consider the condition of the chair! The maintenance of the chair is equally important as
that of the device. Manufacturers recommendations may not consider the use of the chair with the device, so please
contact your chair supplier to ask about maintenance when using a device!
Parts (shown below) also include “generic” care instructions for the chair. These should be considered along with the
chair manufacturer’s own care instructions., which should be regularly inspected.

At least once a month,
depending on usage
conditions.

Version 01/21 Page 11 of 44 PAWS UM EN
Turning wheels
The area between the fork and the front wheel should be kept clean,
because dirt accumulating there can cause faster wear of caster
bearings. To do so, one should disassemble the front caster by
disassembling it from the fork, to remove all dirt, and then preserve
the metal elements of the wheel (i.e. to apply technical grease).
The maintenance ought
to be made once a
month or more often
depending on usual
surface type &
conditions.
Detachable
elements
Check the condition of detachable elements of the chair; if screws
are loose, they should be tightened.

10 Configurations, Controls and Display.
Description
The configuration of the device is made at the time of ordering and may involve a therapist with the dealer and Use
discussing the options that best suit the Users situation.
Thus, the set-up of controls of the device will be matched to the driving, braking, and docking options chosen by the
User at the time of ordering.
While most features are standard, there are options in the Docking, Driving and Braking Systems to allow the User to
have the level of control that does not exceed their physical abilities.
Generally, Users with neural damage and/or muscle atrophy will choose auto or assisted docking, driving and braking
controls.
Attention! These are set during manufacture and can only be changed by the Manufacturer or authorised
dealers with approved components.
Configuration
The needs of the User determine the set-up of the device and controls. The set-up offering the most assistance is for
Users with restricted neuro-muscular abilities.

Version 01/21 Page 18 of 44 PAWS UM EN
Assistance is in 2 forms
Power Assisted Docking –Clamping/Unclamping & Lifting/Lowering
Driving and Braking –Tetra controls to support these actions
The Tetra Handlebars for those with diminished trunk and upper extremity strength and fine motor control. The main
difference is the gripping method for the hand controls for throttle (right hand) and brake (left hand).
For the Tetra Handles, there are two additional prongs that allows the Users hands and wrists to be more actively
employed in the control movement.
The angle of the Tetra Handles will need to be set-up individually for optimal control.
Attention! The ability of the User to control the key functions of speed control and braking will determine if it is
safe to use or not.
Controls
The controls are switches, buttons or levers that are used to operate the device. They describe the 5 main “systems” of
the device: -
Power –Battery and Device
Safety –Lighting and Warning
Docking –Clamping/Unclamping & Lifting/Lowering
Driving –Accelerating/Decelerating
Braking –Slowing down & Parking
