Micro 4K choke adjustment procedure

[udidwht]

The correct method for adjustment is as follows:

1. Allow the gen set to cool down. In side the housing needs to be the same as ambient temp.

2. Loosen the adjustment screw holding the adjustment plate.

3. Slowly rotate the adjustment plate until the bi-metal choke shaft connection is visible in the sight window. This is the correct setting for ambient temperature of 70 F (21 C) If the ambient temperature is higher or lower than 70 F (21 C), make a mark on the choke coil housing opposite the center mark on the adjustment plate. Each mark on the adjustment plate is equal to 10 F (12.2 C) of difference from 70 F (21 C). If it is warmer than 70 F (21C), rotate the plate clockwise. If the temperature is less than 70 F (21 C), rotate the plate counterclockwise. Tighten the adjustment screw.

Example: If the ambient temperature is 90 F(32 C), rotate the adjustment plate two marks clockwise from the 70 F (21 C) position marked on the housing.

4.Move the choke lever back and forth to check for free movement. Verify that the choke does not bind or stick.

A throttle stop screw is provided for adjusting the
“closed” position of the throttle plate to obtain proper governor response when loads are being disconnected. (See Governor Adjustments on Page 8-9)

To adjust the throttle stop screw:

1. Connect a frequency meter and start and run
the genset until it has warmed up to normal operating temperature.

2. Disconnect all loads. Pull the governor linkage
toward the front of the genset so that the tang
on the throttle lever bears against the throttle
stop screw. Adjust the stop screw to obtain a
frequency of 54 to 56 Hz on 60 Hz gensets (44
to 46 Hz on 50 Hz gensets).
