3.5 Engine Break-In
Break-in of the POWER JET’s Top 80 Engine is required before the first flight. Proper break-in will
provide you with a better running engine. It will also provide for considerably longer engine life.
During the break-in, gently change RPM from idle to full-throttle and back. Do not rapidly change
RPM, as this causes unnecessary wear and tear on the clutch. The procedure is as follows:
x
Run the engine, varying the RPM, for 2 minutes.
x
Stop the engine and let it cool for 2 minutes. Check for loose bolts, etc. during this time.
x
Run the engine, varying the RPM, for 5 minutes.
x
Stop the engine and let it cool for 5 minutes. Check for loose bolts, etc. during this time.
x
Run the engine, varying the RPM, for 10 minutes.
x
Stop the engine and let it cool for 5 minutes. Check for loose bolts, etc. during this time.
x
Continue 10 minutes of running, 5 minutes of cooling until 30 minutes of run time is
achieved.
At this point, you can fly the POWER JET, however avoid long durations of full power, and vary the
throttle setting often.
For heavier pilots that require more power to fly, it is recommended that 1 hour of non-flying break-in
be completed before flying.
Break-in is complete after 10 liters of fuel have been run through the engine.
CAUTION!
Be wary of overheating during the break-in process. It will show itself as a loss of power.
Should this occur, reduce power and land as soon, as is practicable. Allow the engine to cool.
Check to ensure the carburetor mixture is correct (a lean condition can also produce overheating) before
flying again.
3.6 Harness Adjustment
The PJ125’s harness consists of two separate strapping systems, one used to comfortably support the
paramotor assembly unit on the pilot’s back while on the ground, and the other is used to support the
paramotor and pilot while flying. This system also correctly aligns the thrust angle of the prop. The
two systems have separate purposes, and are adjusted separately.
