TUNING, ADJUSTING &
MAINTAINING YOUR VEHICLE
• Examine your vehicle on a regular basis.
• Use a brush to remove dirt and dust.
• Look for damage to the suspension arms and other molded parts.
• Re-glue the tires to the wheels, if necessary.
• Use suitable tools to tighten fasteners.
• Make sure the camber and steering linkages are not bent. Replace any bent linkages.
• Adjust the Toe and Camber settings, if necessary.
• Remove the shocks and inspect them for damage. Rebuild the shocks if oil is leaking.
• Inspect electronics and batteries for exposed wires. Repair exposed wires with shrink-
wrap or replace the wire.
• Make sure the ESC and receiver are secure on the chassis. Replace the double-sided tape,
if necessary.
• Power on the transmitter. If the green LED is dim or off, replace the AA batteries
in your transmitter.
• Check the spur gear for wear.

SERVICE/REPAIR
RADIO/SPEED CONTROL & MOTOR
If any problems other than those covered in the troubleshooting section arise, please
call the appropriate electronics service department. They will be able to give the problem
additional specifi c attention and provide instructions for the solution.
MAINTENANCE
If any questions other than those covered in the troubleshooting or maintenance sections
arise, please call the appropriate Horizon product support department.
CLEANING
Performance can be hindered if dirt gets in any of the moving suspension parts. Use
compressed air, a soft paintbrush, or a toothbrush to remove dust or dirt. Avoid using
solvents or chemicals as they can actually wash dirt into the bearings or moving parts,
as well as cause damage to the electronics.
