1  Introduction 
This section summarizes all of the very important warnings that appear throughout the text of this manual. Do not install, maintain 
or operate the scooter without reading, understanding and observing the following warnings. Failure to observe these warnings 
could result in UNSAFE CONDITIONS for the user of a scooter or affect the reliability of the controller. PG Drives Technology accepts 
no liability for losses of any kind arising from failure to comply with any of the conditions in the warnings listed below. Failure to 
observe these warnings will invalidate the S-Drive warranty.

identified  below  have  been  addressed  within  their  own  scooter  designs  and  associated 
documentation. 
2  Warnings 
2.1  Driving Technique 
The scooter user must be capable of driving a scooter safely. PGDT accepts no liability for losses 
of any kind arising from failure to comply with this condition. Chapter 1 section 5.2. 
2.2  Hazards 
Although the S-drive is designed to be extremely reliable and each unit is rigorously tested during 
manufacture, the possibility of system malfunction always exists (however small the probability). 
Under some conditions of system malfunction the control system must (for safety reasons) stop 
the scooter instantaneously. If there is any possibility of the user falling out of the scooter as a 
result of a sudden braking action, it is imperative that a restraining device such as a seat belt is 
supplied with the scooter and that  it is in use at all times when the scooter is in  motion.  PGDT 
accept no liability for losses of any kind arising from the unexpected stopping of the scooter, or 
arising from the improper use of the scooter or control system. 
Do  not  operate  the  S-Drive  if  the  scooter  behaves  erratically,  or  shows  abnormal  signs  of 
heating,  sparks  or  smoke.  Turn  the  S-Drive  off  at  once  and  consult  your  service  agent.  PGDT 
accepts no liability for losses of any kind arising from failure to comply with this condition.  
Electronic  equipment  can  be  affected  by  Electro  Magnetic  Interference  (EMI).  Such  interference 
may be generated by radio stations, TV stations, other radio transmitters and cellular phones. If 
the chair exhibits erratic behavior due to EMI, turn the control system off immediately and consult 
your service agent. PGDT accepts no liability for losses of any kind arising from failure to comply 
with this condition
. 
It  is  the  responsibility  of  the  scooter  manufacturer  to  ensure  that  the  scooter  complies  with 
appropriate  National  and  International  EMC  legislation.  PGDT  accepts  no  liability  for  losses  of 
any kind arising from failure to comply with this condition. 
The  scooter  user  must  comply  with  all  scooter  safety  warnings.  PGDT  accepts  no  liability  for 
losses of any kind arising from failure to comply with this condition. Chapter 1 section 6.1.
