Wear
Check: That the motor runs smoothly
and evenly. If not, the carbon brush-
es in the motor usually need to be
replaced. The minimum length of the
brushes is 1-1.5 cm. See the Spare

Check: The gear wheel in the transax

measure the play around the periphery
of the tyre. On a new machine the play
is 16-18 mm. If the play is much bigger,
replace the whole unit. See the Spare

Check: The rear wheel bearings in the
gear for wear. Lift the rear of the scoot

er. Get hold of one wheel at a time. Lift
it up and down to see if there is any
play in the bearings in the transaxle.
If there is, the whole unit should be
replaced.
