MAINTENANCE AFTER RUNNING
*After a run of the radio controlled car, remove the Ni-cad battery from the car and store
it separately.
*When you have finished running the car, clean dirt off the car.
*Turn off the switches of the radio control units without fail.
*Apply grease on the moving parts regularly.
*Check that all screws and nuts are tightened properly.
HANDLING THE MOTOR
*The motor becomes hot after each run. So continuous running may shorten its life. Do not
run the car until the mo tor gets cool after each operation.
*After several runs the mo tor may lose its power. This is because of carbon accumulated
on the commutator of mo t or. In such a case, remove the pinion gear and run it idly for
15 minutes under 7. 2 vol ts.
*Oil the bearings of mo t or periodically.
