7. Driving

a) General Information
Attention!
It is always extremely important not to make the fuel mix too lean! Observe that the engine is lubricated by the oil in the fuel in this two-stroke
engine. Too little oil in the air/fuel mix will cause the engine to overheat and the piston to seize due to defective lubrication. Loss of guarantee/
warranty!
During operation, a slight white smoke vane should be visible from the exhaust at all times. If this is not the case, stop driving at once and enrich the mix by
turning out the main nozzle needle.
Also make sure that sufficient air circulates around the cylinder head in order to avoid overheating. If necessary, create a corresponding opening in
the car body.
The best engine operating temperature is approx. 100 – 120°. Check the temperature with a suitable measuring device or a drop of water on the cooling head:
If the water evaporates suddenly, the engine is too hot. At operating temperature, the water evaporates in 3 – 4 seconds.
Make sure that the rechargeable batteries of transmitter and receiver are fully charged.
Check the range of the remote control transmitter and the function of the RC system.
Always drive with the car body put on. Thus, you protect yourself from burns if you touch the engine or the manifold by accident and you protect the
components from damage by whirled-up stones.
Familiarise yourself with the curve behaviour. Practice steering with the model driving towards you!
b) Effect of Manner of Driving on Individual Components
Engine
The model's FORCE combustion engine is air cooled. This means that the airstream has to cool down the engine (air cooling).
This is why you should try to avoid accelerating the vehicle from a low speed range with frequent, strong throttle surges (followed by sudden reduction of the
speed). The short-term high speeds will strongly heat the engine without the corresponding cooling from airstream being ensured. At continuous speed at higher
revs (higher speed) the airstream will cool the engine sufficiently.
As a result of overheating the engine, the piston may get stuck in the cylinder liner (piston gets stuck) and suddenly block the drive. This could cause consequential
damage to the entire drive train. Loss of guarantee/warranty!
At continuous slow driving, observe that the engine may be cooled sufficiently, but damage may also occur to the centrifugal clutch due to
unintended "dragging". The centrifugal clutch will only engage well enough to avoid slipping as of approx. half the speed. At lower speeds,
increased wear and/or overheating of the clutch may result. Also see the next chapter.
Clutch
The clutch will not engage at idle speed. The model keeps standing still with running engine.
When the engine speed is increased slowly, the clutch "slips". The vehicle starts up or runs slowly. Just as with a "real" car, constant slipping of the clutch can
cause the clutch lining to "smoke away" or "burn off".
The clutch "engages" properly at higher engine speeds. The engine speed is transferred to the drive train without slippage. Wear of the clutch linings is now at
its lowest.
Frequent strong load changes from short throttle surges and sudden reduction of speed will also reduce the clutch liner service life. Short throttle
surges and slipping of the clutch will lead to slow driving speed at the expense of the clutch.
Bearing
Overheating the engine and/or the clutch also has an effect on the clutch bell bearings.
Running out and resinification of the bearing grease (running dry of the bearing) and different expansion of the balls and running cage at excess heating will
cause the balls to seize.
If the balls can no longer move freely, there is frictional loss and therefore an additional heating up of the engine shaft.
c) Driving in Unsuitable Weather and Ambience Conditions
The remote control system components are not water-proof! Close the receiver box carefully by not only snapping the lid into place but also by
pushing the latch forward.
Avoid driving through water puddles, in snow or rain. If your model has become wet anyway, stop driving at once and dry it with suitable measures.
