7. Operation

a) General
Enrich the mixture by adjusting the main jet needle again, but keep the setting lean enough for the engine to run optimally.
Caution!
It is extremely important not to make the mixture too lean! Keep in mind that the engine lubrication of the two-stroke-engine is effected via the oil
contained in the fuel. Too little oil in the air-fuel mixture causes engine overheating and piston seizure because of insufficient lubrication.
During operation, a light white trail of smoke coming out of the exhaust pipe should always be visible. If not, stop the engine immediately and enrich the mixture.
Also make sure that sufficient air circulates around the cylinder head to avoid overheating. If necessary, cut a corresponding opening into the car
body.
The optimal engine operating temperature is approx. 100 - 120° C. Check the temperature with a drop of water on the cooling head: If the water evaporates
promptly, the engine is too hot. At the proper operating temperature, the water evaporates within 3 - 4 seconds.
Make sure that the rechargeable batteries of transmitter and receiver are fully charged.
Check the range of the remote control and the function of the RC system.
Always try to drive the model at high revolutions! Avoid brief, strong throttle bursts when you want to drive slowly! Avoid frequent slow driving with
slipping clutch!
Always drive with the car body attached. Thus, you protect yourself against burns if you touch the engine or the manifold by accident and you
protect the components from damage by whirled-up stones.
Bear in mind that the operation of remote controlled vehicles has to be learned step by step. Start with simple driving exercises, e.g. driving in
circles. Use pylons or racing discs to delimit a course.
Get used to the driving behaviour in curves. Practice steering with the model running towards you!
b) Effect of way of driving on the individual components
Engine
The FORCE combustion engine is air-cooled. This means that the air stream cools the engine (air-stream cooling).
This is why you should try to avoid accelerating the vehicle with frequent, big load changes (short throttle bursts from low rev range and suddenly lowering the
revs). The brief high revs strongly heat up the engine, without there being appropriate cooling through wind as would be the case when driving at constantly high
revolutions (high speed).
As a result of overheating of the engine, the piston may get stuck in the cylinder liner and suddenly block the drive. This could cause consequential damage to
the entire drive section.
Drive in part-load operational range with revs that correspond to the desired speed.
However:
If you are continuously driving slowly, the air-cooling of the engine is provided for, but there may be damage to the clutch (wear, overheating through
slipping clutch).
Clutch
At idle speed, the clutch does not engage yet. The model is on the ground with the engine running.
When engine speed is increased slowly, the clutch slips. The vehicle starts or moves slowly. Just as with a real vehicle, constant slipping of the clutch can cause
the clutch lining to "smoke away" or "burn off".
The clutch engages at higher engine speeds. The engine speed is transmitted sliplessly to the drive section. The wear on the clutch linings is now at its lowest.
Frequent, strong load changes by brief short throttle bursts and jerky lowering of the revs also reduce the life of the clutch linings. With short throttle
bursts as well as by letting the clutch slip, you can drive at low speed, but at the expense of the clutch.
Bearings
Overheating of the engine and/or the clutch also has an effect on the bearings of the clutch bell.
Leaking and resinification of the bearing grease (bearing runs dry) as well as different expansion of the balls and the ball bearing case in the case of excessive
heat can lead to a jamming of the balls.
If the balls can no longer move freely, there are frictional losses and therefore the engine shaft heats up additionally.
