If you have any problems other than those covered in the troubleshooting
section, please call the appropriate electronics service department. They will
be able to give your specific problem additional attention and instruct you as
to what needs to be done.
Maintenance
If you have any questions other than those covered in the troubleshooting or
maintenance sections, 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 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.
