Maintenance
Batteries
If this unit is not being used for an extended period of time, it should be connected to
the battery charger to check the battery level on a regular basis, and placed on charge
overnight if required. This will ensure the batteries are kept in good condition.
The batteries are sealed and maintenance free. DO NOT attempt to open these
batteries. If the unit is not charged as above, the batteries may be exhausted and have
dropped below the charging threshold of the battery charger. The supplied charger
cannot begin to charge the batteries unless they have a small amount of charge. If this
occurs, contact Electrodrive or your local service agent.
A sign that the batteries need replacing is when they no longer hold charge.
Tyres
The tyres are polyurethane, giving it punture-proof characteristics. For replacement
tyres, contact Electrodrive or your local service agent.
Brakes
The dynamic braking system does not require regular maintenance.
Motor
Motor brushes should be inspected every six months and replaced every 2 years.
Remove the brush retaining cover for access to the brushes, should they need
replacing.
Motor controller
This unit is not serviceable. Any difficulties experienced with speed control should be
referred to Electrodrive.
Throttle lever
The throttle lever and cable do not require maintenance. Should the lever or cable suffer
damage they should be replaced. If the handle loosens with wear, the hinge nut can
be gently tightened. However, first confirm that the lever is in the correct position as it
may need to be reset. (Test by squeezing the lever slightly. The Tug Smart should slowly
move, release and the Tug Smart should completely stop).
Fuses and circuit breakers
The control circuits and power circuits are protected against inadvertent current over-
loads. These fuses are located adjacent to the controller under the top cover.
