Station to have the following services performed.
Verify that all daily, weekly, monthly and quarterly
maintenance has been performed.
Inspect Drive Motor carbon brushes for wear.
This will require removing the drive motor from the
machine and should only be done by an authorized
NSS Service Station.
Using compressed air, blow the accumulated
carbon brush dust out of the motor.
Replace carbon brush when they measure ½”
[12.7mm] or less in length.
Failure to replace carbon brushes will cause poor
machine performance and possible motor damage.

above. Use a jack and or jacks capable of supporting
the weight of the machine. Position the machine on a
flat level surface and block the wheels. Two jacks are
required for rear wheel removal, one on each side.

must be replaced. If you cannot compress it, it is
most likely OK.
