MAINTENANCE
Lubricating Your Machine
WARNING
Unit must be switched “OFF” before greasing wheel
fittings. Wipe off excess.
Once a week grease swivel casters with grease gun
provided. Each caster has two fittings: one at the axle
(A) and one on the swivel part of caster (B).
Motor Brush Replacement
Use the appropriate hour meter on the LCD Display to monitor runtimes for each motor.
Tornado recommends changing motor brushes at the intervals specified below in order to avoid
potential damage to the commutators. Replacement brushes need to be inspected and
changed more often due to commutator wear. Always permanently record any brush
inspections and replacements you make.
Don’t attempt to use the Motor Fault Error feature of the LCD Display as a signal that motor
brushes need changing. A Motor Fault that occurs directly from brush wear would indicate a
high risk of motor damage.
Motor Recommended Motor Brush Change Interval
Transaxle 1800 hours initially, 900-1400 hours for replacements
Brush 2600 hours initially, 1300-2000 hours for replacements
Vacuum 600-650 hours initially, 400-500 hours for replacements
