Rock Runner/Car Crusher (600-4133) Maintenance Faxback Doc. # 6604 To enjoy the vehicle for a long time: Don't drop the vehicle. A fall might damage it. Never take apart the vehicle or the transmitter. Do not drive the vehicle in water, sand, or on thick carpet. Modifying or tampering with the vehicle's or the transmitter's internal components can cause a malfunction and might invalidate the warranty and void your FCC authorization to operate the vehicle. If your vehicle does not work properly, take it to your local Radio Shack store for assistance. (LB/all-08/17/94)
