2. Set control panel system switch to off
3. Remove 15 Amp fuse from system control panel.
4. Remove Zero Pressure Regulator (ZPR) tower cap (a).

generator. Check and adjust (a) and (B) to achieve
target value.
18. Remove load and check if sensor value remained
in target area. If needed, adjust (a) and (B) to achieve
target value.
19. Add half, then full load to generator. Recheck and
verify sensor value remains in target area.
iMPortant: It may take several attempts to achieve the
target setting. Continue to test and adjust with engine
stabilized at no, half and full loads until target value is
achieved at all generator loads.
20. Remove load from generator. Allow generator to
run for ten minutes to stabilize internal temperatures.
Turn control panel system switch to off.
21. Remove 15 Amp fuse from system control panel.
WarninG Contact with muffler and engine parts can result in
serious burns.
DO NOT touch hot parts and AVOID hot exhaust gases.
Allow equipment to cool before touching.
