When  you  replace  worn  out  batteries,  fit  the  type  recommended  by  the  scooter  manufacturer.  If  you  use  another  type  the 
battery gauge may be inaccurate. 
The  amount  of  charge  in  your  batteries  depends  on  a  number  of  factors,  including  the  way  you  use  your  scooter,  the 
temperature of the batteries, their age and the way they are made. These factors will affect the distance you can travel in your 
scooter. All scooter batteries will gradually lose their capacity as they age. 
The most important factor that reduces the life of your batteries is the amount of charge you take from the batteries before you 
recharge them. Battery life is also reduced by the number of times you charge and discharge the batteries.  
To make your batteries last longer, do not allow them to become completely flat. Always recharge your batteries promptly after 
they are discharged. 
If your battery gauge reading seems to fall more quickly than usual, your batteries may be worn out.

10  Pushing your Scooter 
The scooter will be fitted with a freewheel mechanism which allows the scooter to be pushed if there is a fault or the batteries are 
disconnected or not fitted. 
Depending  on  the  type  of  freewheel  mechanism,  then  it  may  be  possible  for  the  scooter  to 
freewheel at potentially dangerous speeds. Therefore, do not push the scooter up or down inclines 
on  which  you  cannot  stop  or  hold  the  scooter.  Never  sit  on  the  scooter  if  the  freewheel 
mechanism is disengaged. PGDT accept no liability for losses of any kind arising from the scooter 
being moved while the freewheel mechanism is disengaged. 
11  Programming 
If you cannot find a position on the speed limiting control that suits you, the controller can be programmed to meet your needs. 
The controller can be programmed in two ways – with an SP1 Programmer or specialist PC software and interface cable. 
The SP1 is a small hand-held unit that can be plugged into your controller to alter the program. 
The PC Programmer is a piece of PC software and an interface cable. When the software is installed onto a PC, it can then be 
connected to the controller by using the special interface cable. The controller can then be programmed using a windows type 
environment 
The programming tools may  be included with your scooter. If they are not, your scooter distributor or service agent or scooter 
manufacturer will be able to program your controller for you. 
If you have a Programmer, read the user guide before you use it. 
If  you  re-program  your  controller,  make  sure  that  you  observe  any  restrictions  given  in  your  scooter  user  manual.  Note  any 
changes you make for future reference.  
Programming  should  only  be  conducted  by  healthcare  professionals  with  in-depth  knowledge  of 
PGDT electronic controllers. Incorrect programming could result in an unsafe set-up of a scooter 
for a user. PGDT accept no liability for losses of any kind if the programming of the controller is 
altered from factory preset values.
