9. Maintenance

Engine vibrations and shocks during drive operation can loosen parts and screw connections.
Therefore, check all screws and tighten them if required before and after EVERY drive.

a) General Information

At certain intervals, maintenance work and function controls must be carried out - like customer service for a "real" car - to ensure trouble-free operation and
roadworthiness for a long time. 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.
Regularly check the following for maintenance purposes:
• All wheel nuts and screw connections must be tight. When replacing screws, secure them with thread locker
• The servo control lever must fit tight on the servo shaft.
• Check the fit and condition of the fuel tubes and the air filter.
• Check the tightness of hose connections and tank lid.
• Check placement of the cables.

b) Cleaning

The model is only designed for off-road use and thus often gets dirty. Regular cleaning is required for preserving the model's function.
• Clean the entire vehicle from dust and dirt after driving. Use compressed air and/or a special spray cleaner for this. Never use high-pressure cleaner for this!
• 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 must be removed before cleaning. We also recommend drying the model with pressurized air after washing it.
• Pay particular attention to the bearings. Take off the wheels from time to time and clean the ball bearings of dust and deposits.
• After cleaning, the movable parts must be re-oiled and 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.

c) Brakes

Brake linings and the brake discs wear off with time. Thus, the braking effect decreases as the maximal brake pressure was set according to the thickness of new
linings/brake discs.
If you notice that the braking effect is decreasing, check the brake discs and adjust the position of the adjustment rings on the brake control linkage if necessary.

d) 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.

e) Fuel System and 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
setting. In the most detrimental case, a foreign body between the cylinder liner and piston causes the piston to catch or stick.
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. Model fuel absorbs moisture from the air over time. This moisture will reduce fuel output and lead to
defective engine operation and corrosion in the engine.
• Empty the tank if you do not use the model for several days. The volatile components of the fuel, nitro methane and methanol, evaporate and leave an oil
deposit. This poses a danger of fuel lines, fuel filters and carburettor nozzle needle clogging.
• If you want to stop driving for the day, screw off the glow plug and drip a few drops of after-run engine oil (low-viscosity machine oil) into the cylinder. Insert the
glow plug again and turn the model back and forth overhead a few times so that the oil can distribute in the combustion chamber. This prevents corrosion.
• 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). The oil in the fuel may cause slipping otherwise.
