U-Drive IFU 

Page 6 

Issued 10/11 

Notes: 

 

The battery supplied with the U-Drive is 
classified as safe for air travel by 
compliance with IATA special provision A67. 

 

The battery pack has a handle to make it 
easy to carry. 

 

Battery Charging and Care 

 

The U-Drive can either be charged through the 
joystick (if the battery pack is installed) or the 
battery pack (if this is removed). 

 

Follow the procedure below to charge using the 
joystick: 

1.

 

Switch the U-Drive off. 

2.

 

Plug the charger’s power cord into the 

mains. 

3.

 

Plug the charger’s 

round connector in to the 

socket located underneath the front of the 
joystick unit. 

4.

 

Switch on the plug socket. 

5.

 

The charger’s LED will illuminate orange to 

indicate the batteries are charging. The 
charging duration is about 8 hours. To 
ensure optimum performance a 12-hour 
charge is recommended. 

6.

 

The  orange  LED  will  turn  green  when 
charging is complete. 

7.

 

Turn off the charger, disconnect the power 
cord  and  the  round  plug  from  the  joystick 
unit. 

 
Follow the procedure below to charge using the 
battery pack: 
1.

 

Switch the U-Drive off. 

2.

 

Remove the battery pack from the U-Drive 
as described previously. 

3.

 

Plug  the  charger’s  power  cord  into  the 

mains. 

4.

 

Plug  the  charger’s  round  connector  in  to 

the  socket  located  by  the  handle  of  the 
battery pack. 

5.

 

Switch on the plug socket. 

6.

 

The  charger’s L

ED will illuminate orange to 

indicate  the  batteries  are  charging.  The 
charging  duration  is  about  8  hours.  To 
ensure  optimum  performance  a  12-hour 
charge is recommended. 

7.

 

The  orange  LED  will  turn  green  when 
charging is complete. 

8.

 

Turn off the charger, disconnect the power 
cord  and  the  round  plug  from  the  battery 
pack. 

 

 

Suggestion 
1.

 

Do  not  disconnect  the  charger 
cord  if  charging  is  not  completed. 
The  battery  life  will  be  seriously 
shortened  or  decayed  if  the 
battery  is  repeatedly  used  without 
being  fully  charged.    Therefore  be 
sure  to  charge  the  battery  fully 
every time. 

2.

 

Always complete the charging until 
the  LED  light  turns  green.  NEVER 
stop charging before it is complete. 

3.

 

When  fully  charged,  the  battery 
charger  will  still  trickle  charge  the 
battery to ensure optimum range. 

4.

 

If  you  do  not  use  your  powerpack 
for  a  long  time,  it  should  be 
charged  at  least  every  week  to 
keep  the  battery  in  a  fully  usable 
condition.  

5.

 

The  ambient  temperature  will 
affect charging time. Charging time 
will be longer in the winter. 

6.

 

After  charging,  do  not  leave  the 
charger  socket  plugged  in  to  the 
battery pack or joystick, as this will 
cause a power drain on the battery 
pack  and  temporarily  reduce  its 
range. 

7.

 

The batteries carry a twelve-month 
manufacturer's 

warranty. 

This 

warranty 

only 

covers 

issues 

relating  to  manufacturing  faults, 
and not faults relating to failure to 
recharge 

the 

batteries 

as 

instructed above.
