6. BATTERY CHARGING AND CARE
WARNING
 Keep away from flammable objects
while charging as it may lead to fire or
battery explosion.
 Do not smoke while charging as the
battery may release hydrogen gas.
Always charge the batteries in a well
ventilated environment which is not in
direct sunlight. Do not charge in
surroundings where it is humid, wet or
damp.
 Do not handle the charger, scooter or
mains socket with wet hands, as this
could lead to electric shock.
Follow the procedure below:
1. Switch the ignition off.
2. Connect the charger power cord in to the
mains socket.
3. Open the charging socket cap on the scooter
tiller. Then connect the charger round plug in to
the scooter charging socket located on the left
hand side of the tiller.
4. Switch the charger on at the mains.
5. Both the charger’s red and orange LEDs will be
lit when charging commences. The charging
duration will be around 12 hours. To ensure
optimum performance an 18 hour charge is
recommended. We do not recommend the
scooter be charged for longer than 24 hours.
6. Both the charger’s LEDs will be lit during the
charging process. The orange LED will turn
green when bulk charging is complete after
which the charger trickle charges the batteries.
Trickle charging optimises the batteries and is
necessary to maintain or improve battery
performance.
7. Switch off the charger, disconnect the power
cord and round plug from the charger socket on
the scooter.
Battery Care
1.
2. After charging or replacing a new battery,
drive the scooter for a short period to ensure
battery capacity is sufficient.
3. In cold environments, the battery may respond
more slowly and range will be reduced.
4. When driving on gradients, the battery gauge
will fluctuate. This is a normal occurrence.
ATTENTION
 If only a red LED is lit on the charger,
then the scooter is not connected.
 If no LEDs are lit on the charger, then
the charger is not connected to the
power or it is defective.
 Please only use a charger supplied with
the scooter. You may damage the
battery and / or scooter if you use an
incorrect charger.
 Always charge the battery to its full
capacity every time.
 Do not charge in temperatures below
–10ºC or above +50ºC as the charger
may not work efficiently and the
batteries may become damaged.
Cobra Electric Scooter
You should recharge the batteries after each
time the scooter is used to ensure maximum
battery range. The batteries should be charged
at least once a week even if the scooter is not
used.
5. Battery range is reduced when driving up
gradients or on rough terrain, as the scooter
uses more power.
6. The batteries should not be charged for more
than 24 hours.
7. The batteries are sealed, and so do not need
topping up with water.
8. The batteries should be checked periodically
for cleanliness. Please refer to the section later
in the handbook.
Page 10 of 16
Owner’s Handbook (Code: KCobra_IFU 01/14)
Battery Replacement
It is natural for the battery capacity to reduce with
time, even if the battery is charged as directed above.
When the battery range is about half of its peak
performance we recommend that the batteries are
changed. Continuing to use an old battery will result in
a rapid reduction in the range of the scooter and can
cause excessive wear and tear on other parts of the
scooter. It is recommended that batteries are replaced
in pairs, and that these are fitted by your dealer.
Cleaning the Battery
If the batteries are contaminated by water, battery acid,
dust or other substances, they will discharge quickly.
The batteries supplied with the scooter are sealed and
as such are maintenance free with no risk of battery
leakage. Please follow the steps below to clean the
battery:
1.
Remove the batteries following the procedure
above.
2. Clean the battery with a clean cloth. If the
terminal is covered by white powder, wipe it
cleaning using warm water.
Removing the Batteries
1.
Switch off the scooter at the ignition and
remove the seat.
2. Lift up the battery cover (A)
3. Disconnect the black battery connectors (B)
and red battery connectors.
4. Remove the velcro straps (C) from the
battery and pull the battery out.

7. INSPECTION AND MAINTENANCE
7.1 Checks and Maintenance
Your power scooter is designed for minimal
maintenance. However, like any motorized vehicle it
requires routine maintenance. To keep your scooter for
years of trouble-free operation, we recommend you
follow the following maintenance checks as scheduled.
Weekly Checking
Check the following items weekly or before driving. If
you find anything abnormal contact your Drive Medical
Dealer for further inspection or advice.
 Tiller. Ensure it is not loose and can turn smoothly
 Speed control dial. Ensure it adjusts freely.
 Wigwag paddle. Ensure scooter moves when lever
is pressed, and stops when lever released.
 Motor. Check for any abnormal noise and
electromagnetic brakes work correctly.
 Freewheel Lever. Ensure it works correctly.
 Seat. Ensure it swivels and locks easily.
 Tyres. Check tyre tread depth and for any signs of
damage such as cracking.
All moving mechanisms will benefit from simple
lubrication and inspection. Lubricate using petroleum
jelly or light oil. Do not use too much oil, otherwise
small drips could stain and damage carpets and
furnishings etc. Always perform a general inspection
of the tightness of all nuts and bolts.
Semi-Annual Checks
Check the motor brushes. We recommended that your
authorized dealer inspects the brushes every six
months or sooner if your power scooter is not operating
smoothly. If inspection determines excessive wear on
the brushes, they must be replaced or motor damage
will result.
The brushes should be inspected for wear and colour of
the braiding inside the spring. If the braiding is dark
brown, red, silver, purple or gold then the brush needs
replacing.
Warning! Failure to maintain the brushes could void the
power scooter warranty.
To inspect or replace the motor brushes:
1.
Unscrew the motor brush caps (by using a
screwdriver on the caps shown by the white
arrow).
2.
Remove the brushes.
3.
Inspect the brushes for wear (replace if less
than 9mm)
4.
Replace the brushes if necessary.
Monthly Checks
Visually inspect the controller harnesses. Make sure
that they are not frayed, cut or have any exposed wires.

Make sure you keep the controller clean whilst
protecting it from rain or water. Never hose off
your scooter or place it in direct contact with
water.

Keep wheels free from lint, hair, sand and carpet
fibres.

Visually inspect the tyre tread. If less than 1mm
(1/32”), please have your tyres replaced by your
local dealer.

Less than 9mm
All upholstery can be washed with warm water
and mild soap. Occasionally check the seat and
back for sagging, cuts and tears. Replace if
necessary. Do not store your scooter in damp or
humid conditions as this will lead to mildew and
rapid deterioration of the upholstery parts.
Cobra Electric Scooter

Owner’s Handbook (Code: KCobra_IFU 01/14)
7.5 Storage

Inspect the state of the battery terminals every six
months. Make sure that they are not corroded and
the connections are tight. Periodically apply a thin
film of petroleum jelly on the surface of terminals
to guard against corrosion.
7.2 Service Record
To ensure your scooter is correctly serviced take it to
your Drive Medical dealer for regular servicing. We
recommend that scooters are serviced at least annually,
and your dealer may charge a fee for this.
A copy of the service record is at the back of this
handbook. Copies of the servicing schedule are
available from Drive Medical to authorised parties on
request.
Even if the scooter has not been used, it
should still be serviced annually.

Store the scooter in environments which are
free from direct sunlight and water or
moisture.
7.6 Moving About
1.
Switch off the scooter using the ignition key and
dismount from the scooter. We also recommend
removing the seat and batteries prior to moving.
2.
Lift the scooter by the chassis only.
3.
For your safety ask for help if required. You will
need two or more people when moving or lifting
the scooter as a whole.
Never lift the scooter by the bumpers or
body panels, as this can cause injury or
damage.
7.3 Battery Pack and Tyres
 For information on the battery pack, please read
section 6 on Battery Charging and Care.

Tyre condition will be affected by how you drive
the scooter and what terrain it is driven on.

The Cobra comes with pneumatic tyres, with a
recommended inflation pressure of 26 psi (1.8bar)
The tyre pressure should be periodically checked.
Ensure the scooter is stored with the seat set in
the forward position, the scooter switched off with
the battery pack removed and charger
disconnected.
7.4 Cleaning

The scooter should be cleaned periodically,
especially if you tend to drive on sand, gravel or in
other adverse environments.

Use a soft, wrung dry cloth to keep your scooter
clean and dust free. Use a damp cloth and mild
detergent to clean the scooter.
Warning
 Do not use a hose pipe or splash water
directly on to the scooter.
 Do not use petrol, solvents or vaporising
solutions as these many damage body
panels. Do not use wax
 Ensure the charger is unplugged and the
scooter switched off before cleaning the
scooter.
