Cleaning and Maintenance
If you have driven the vehicle before, let all parts (e.g. motor, exhaust, etc.) cool down completely first.
Clean the whole vehicle of dust and dirt after driving, e.g. with a long-haired clean brush and a vacuum cleaner.
Compressed air aerosols can also be helpful.
Do not use cleaning aerosols or conventional household cleaners. This may damage the electronics and
lead to discolouration of the plastic parts or the body.
Never wash the vehicle with water, e.g. using a high-pressure cleaner. This will destroy the engine and the
receiver as well as the servos. The vehicle must not become damp or wet!
A soft cloth, slightly dampened, can be used to wipe the car body. Do not rub too hard to avoid scratch marks.
At appropriate intervals, you should perform maintenance work and function checks on the vehicle. This ensures
trouble-free operation and road-worthiness for a long time.
Motor vibrations and shocks during driving can loosen parts and screw fittings.
Therefore, check the following items before and after driving:
• Tight fit of wheel nuts and of all vehicle screw fittings
• Servo attachment
• Glue-connections of tyres and rims or tyre condition
• Attachment of all cables (they must not get into movable parts of the vehicle)
Also check the model for damage before each use. If you find any damage, the car may not be used
anymore and has to be taken out of operation.
Only original spare parts must be used to replace worn vehicle parts (e.g. tyres) or defective vehicle parts
(e.g. a broken transverse link).
Check, the following positions regularly after several drives:
• The air filter must be oiled, clean and undamaged to filter out even the finest dust, e.g. in a dusty environment.
• All moveable parts and parts with bearings must be lubricated with a low viscosity machine oil or spray grease after
cleaning of the model or several drives.
• Check looks and contact distance of the spark plug.
Spark plugs wear, especially in the running-in phase. Therefore, we recommend that you always keep some spark
plugs at hand for replacement.
Only use spark plugs of type „CMR 7H"! Wrong or worn spark plugs will cause the engine to run incorrectly and
impairs reconciliation. Installation and replacement of the spark plug requires a spark plug wrench (lug wrench
SW10). The ideal electrode distance of intact spark plugs is 0.7 mm.
