requires routine maintenance. To keep your scooter for
years of trouble-free operation, we recommend you

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.

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.
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.

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
is designed for minimal
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.
