The symptoms of too lean mixture at idle speed could be:
The tendency to cut out and problems with keeping low speed on cold engine, especially
right after the start. The engine works irregularly, vibrates strongly, stops. Loosening the „L”
screw a bit causes speed decrease, but the engine works more steadily and does not cut
out.
The cold engine very often cuts out after the start and it is impossible to start it again
without a slight re-fueling with the fuel pump. This does not refer to the situation when the
engine was not filled with enough fuel.
After adjusting the composition of idle speed mixture you should perform the high speed
adjustment again – „H” screw.
7. Storing the paramotor and other maintenance operations.
While storing the paramotor in a standing position you should loosen up the fuel tank
stopper. Even small changes in the surrounding temperature may cause significant pressure
changes in the sealed tank. When planning long-term storing of the paramotor, you should
empty the fuel tank completely, completely remove the wires, and the carburetor. It is
extremely dangerous to leave even the tiniest amount of fuel in the sealed tank in highly
sunlit place or other place where intense heating (car trunk etc.) could occur.
You should also remember not to store the paramotor in humid places because it could
influence its technical and visual state. Direct exposition to such conditions is not covered by
the warranty.
7.1 Pre-flight paramotor check-up – daily check-up.
•
Check and evaluate general state of the paramotor’s parts by looking for cracks,
leaks etc.
•
Check the engine mounting, check the fuel system for leaks, and check the way the
shifter and the throttle work.
•
Pay special attention to the state of the exhaust system. Check the silencer
mounting, condition of all threaded connections, and rubber shock absorbers.
•
Check the propeller’s mounting, clean oil deposits, soot and other impurities from the
propeller. Treating the propeller with a piece of cloth will help you to find cracks and
other damages.
•
Check the electric installation thoroughly looking for mechanical damage, abrasions,
joints or some disconnections between the elements.
•
Check the engine starter.
•
Pay special attention to all leakages, scratches and atypical stains. In case of any
doubts, contact a Techno-Fly representative.
•
Check the frame and the propeller cage. Check the construction’s geometry. Inspect
thoroughly harness settings, condition of tapes, carbines and braking system.
7.2 The paramotor’s maintenance and servicing – recommended operations.
After first 5 hours:
1. Check the tightening of all screws and nuts (visual control).
2. Check the tightening of the head (torque 13 Nm)
3. Check the internal carburetor filter (by unscrewing 4 screws on fuel pump’s cover-WG37)
