Operation Notes
Ensure propeller cannot contact anything or anyone. (In the case of a paramotor, machine must
either be 1. Securely strapped to a pilot or 2. Securely fixed to proprietary test rig.)
DO NOT start your paramotor unless one of these 2 rules is obeyed.
Running-in
Your V5 engine has been fully tested prior to customer release, but you must adhere to the following procedure
to ensure no damage is caused to your engine in the first few critical running hours. After the first 10 running
hours, your engine will be run-in and you must perform an oil and filter change and check the valve clearance
settings, as is shown on the service schedule on page 11.
During the running-in period (first 10 hours) full power can be used for take-off. Once airborne power should be
reduced to a maximum of 75%. Varying the engine RPM during this period is recommended. Running-in on the
ground is strongly discouraged.
Starting
On the V5 (manual start) CVK carburettor there is no choke (cold start enrichment device) fitted. Instead there is
an accelerator pump connected to the throttle mechanism. On V5E (electric start) models there is an electric
choke unit fitted.
Starting – Cold Start:
A) First ensure the carburettor is full of fuel by squeezing the primer bulb
B) Check throttle is closed fully, after opening and closing to test operation
C) Pump the throttle several times (5-10 times, depending on temperature)
D) Keep the throttle very slightly open
E) Use pull starter handle to start engine
F) Once started maintain a fast idle for at least 60 seconds
G) Momentarily press stop button to check operation
If the ambient temperature is very cold you will need to continue pumping the throttle after starting to maintain a
rich mixture for the first 10 seconds or so, until the engine has reached a sufficient temperature.
Starting – Hot Start:
A) Keep the throttle very slightly open
B) Use pull starter handle to start engine
Prior to starting your Bailey V5 engine, you should have already followed the
full pre-start checklist shown on page 9.
