Tow Tuff TMD-3500ETD hints

• The button below the battery charge indicator is not a temporary push only button to just show the charge, rather it's a push-on, push-off toggle switch. It acts as the controller on/off button. If the indicators don't lite up, the controller is not on.
• The on/off switch on the battery box will stay on for a while after you turn the unit off until the remaining energy is used up.
• There is a small delay when switching directions.
• Since the unit has a differential, if one wheel slips, there is no propulsion.
• The only thing that helps with traction is weight on the main wheels. If you lift the handle up, more weight gets onto the main wheels. Additional weight will be needed to push a plane.
• The "charger" is lame; it's actually a fixed-voltage power supply only, puts out 2A; you are therefore not supposed to charge more than 5 hours, so get a real microprocessor 24V gel charger. The connector goes straight to the battery so easy to hook the charger up instead of the supplied power supply. A suitable charger is SUHU Car Battery Charger, 12V/8A 24V/4A Smart Automatic Battery Charger.
