FINE-TUNING INSTRUCTIONS
Start the engine and observe tank pressure gauge. As tank
pressure approaches 100-130 pound-force per square inch gauge
(PSIG), the pilot valve should begin unloading at the felt muffler
and cause the gas engine to slow down to idle speed.
If the pilot valve does not unload as tank pressure approaches 130
PSIG, slowly turn the top end setting (4) counterclockwise until
pilot starts to unload prematurely (at 100 PSIG.). Turn the top
end setting (4) clockwise in 1/4 turn increments, tap down on the
internal rod at the toggle attachment, and repeat until desired top
end setting is reached.
If the pilot valve begins to rifle (sputter), fine tune differential
setting (2) by a 1/16 turn in either direction until the rifling stops.
After fine-tuning, secure the setting by turning the locknuts (1 & 3)
clockwise until tight. Hold the setting (2 & 4) in place while turning
locknuts to secure.
SCHMIDT BELT-TIGHTENING DEVICE
To tighten belt tension, proceed as follows:
1. Loosen locknuts for engine hold-down bolts only until
washers beneath spin freely.
2. Rotate 1/2 in. adjusting bolt clockwise until desired tension is
reached (A).
3. Retighten locknuts to secure engine.
