and sediment bowl. It should be cleaned
after every 240 hours of operation.
1. Close the shut-off valve.
2. Loosen the jam nut below the glass
bowl and swing the bail aside.
The wire
screen should come away with the bowl, but
if it sticks to the cork gasket it can be re-
moved with the fingers.

STARTING CARBURETOR
The carburetor
is used only in the gas-
oline starting cycle.
The gasoline level is
controlled by a float valve mechanism when
starting and operating on gasoline.
The float
valve is locked into its seat shutting off the
flow of gasoline to the fuel bowl when the en-
gine is changed over to diesel.

The strainer
screen
should be removed occasionally and cleaned.
1. Close the gasoline shut-off valve.
2. Disconnect the gasoline supply pipe
at the carburetor.
3. Unscrew the strainer
screen retainer
from the carburetor
and wash the screen in
kerosene or dry-cleaning
solvent.
Present
day grades of gasoline have a
tendency to form gum.
Therefore
it is
necessary
that the gasoline tank and fuel
bowl be completely drained of fuel when the
engine is to be out of service for more than
two weeks.
These gum deposits can be dis-
solved with a mixture of one part alcohol
and one part benzol, or with acetone.
