9. Cleaning and Maintenance
The model is only designed for off-road use and thus often gets dirty. Regular cleaning is required for preserving the model's function. It must not be cleaned by
a high-pressure cleaning device In general, the air filter and battery and receiver boxes must each be closed off water-tight with a plastics bag or a similar means
or the rechargeable batteries and receiver be removed before cleaning. After cleaning, the movable parts must be re-lubricated. We also recommend to dry the
model with pressurized air after washing it.
A real car must regularly be serviced regularly. For your model, the screws must also be checked for tight fit regularly and any damage that appears must be
removed. Only use original spare parts. Only this will ensure interruption-free operation and keep the vehicle in good driving condition for a long time.
Check before each use:
• All wheel nuts and screw connections must be tight.
• When replacing screws, secure them with screw locking varnish
• The servo control lever must fit tight on the servo shaft.
• Check the fit and condition of the fuel tubes and the air filter.
• The cables must be installed properly.
• Also check the charging state of the rechargeable batteries of the transmitter and the receiver
Engine vibrations and shocks during drive operation can loosen parts and screw connections.
Therefore, check all screws prior and after EACH drive and re-tighten them if necessary.
Cleaning
• After driving, clean the entire vehicle of dust and dirt, use compressed air and/or a special spray cleaner.
• Pay particular attention to the bearings. Remove the wheels occasionally and remove dust and deposits from the bearings.
• After cleaning, the movable parts must be re-lubricated.
• After lubricating the bearings also remove any escaping oil and grease since this is where dust can settle particularly well.
• Also clean the cooling fins of the cooling head regularly with a toothbrush in order to ensure optimum heat dissipation.
Brakes
Brake linings and the brake disks wear off with time. Thus, the braking effect decreases as the maximal brake pressure was set according to the thickness of new
linings/brake disks.
If you observe that the braking effect is fading:
• Check the thickness of the brake disks and
• If necessary, correct the position of the adjusting rings on the brake control linkage.
Lubrication
All moveable parts and parts with bearings must be lubricated with a low viscosity machine oil or spray grease after cleaning and after each use.
Fuel system, engine
• Impurities must not get into the tank or the carburettor and / or especially not into the engine. Such dirt can cause misfiring under load or a bad idle speed
settings. In the worst case, a foreign body between the cylinder lining and piston can cause the piston to get stuck or piston seizure!
• Mount a fuel filter between tank and carburettor to filter out particulate material from the fuel.
• Always use fresh fuel and keep the tank lid firmly shut. With time, fuel absorbs humidity from the air. This humidity reduces the fuel performance and leads to
faulty engine performance as well as engine corrosion.
• Empty the tank if you do not use the model for several days. The volatile components of the fuel evaporate and leave an oil deposit that enriches the fuel mix
and may clog pipes.
• If you do not use the model for an extended period of time, e.g. in winter, drip 2 - 3 drops of preservation oil (accessory) into the cylinder.
• Fix fuel hoses on the connector nipples with thin cable binders or special hose binders (accessories). Das Öl im Treibstoff kann sonst zum Abrutschen führen.
• Occasionally check the fuel filter and the suction head of the membrane pump for contamination and clean them or exchange the filter.
• Check the compression by turning the motor shaft.
