CAUTION: If engine is to be run more than a few
seconds, engine must be cooled using the flush
kit.
4. Check if PTO flywheel mark aligns with timing
tool slot.
NOTE: On this system, timing advance decreases
as engine speed increases.
If timing mark aligns with tool slot, timing is prop-
erly set. If mark does not align with tool slot, re-
check PTO flywheel mark before adjusting ignition
timing to ensure PTO flywheel has not loosen.

1. Timing light pick-up
IMPORTANT: On 787 RFI engines to check the ig-
nition timing, the timing advance curve must be
locked first. This allows to perform ignition timing
at
any RPM by keeping the timing “frozen” so
that it does not vary with engine RPM. See FIXED
TIMING FUNCTION
for more information.
NOTE: Fixed Timing function must be activated
before starting engine.
3. On 947 engines , start engine and rev it to 3500
RPM and point beam of timing light straight in
line with timing mark pointer. On
787 RFI en-
gines , start engine and point the beam of a tim-
ing light on mark.
