designation "heavy") to fill reser-
voir to proper level On Model 400
there are two oil try cocks on left
side of crankcase Oil level should
never be above the upper try cock
and should not be allowed to get
below the lower one On Model FB
oil level guage consists OF a metal
rod, which can be withdrawn from
the left side of crankcase. Oil level
should never be above full" mark
on this rod, and best results will be
obtained if the oil level is main
tanned between full and half full"
marks on the guage. To get a cor
rect reading of the oil level guage,
the automobile should be approx
mately level and the engine not run
ming. When engine is running the
oil pressure indicator on dash should
show pressure which will vary with
the speed and temperature of the
engine. If no pressure is registered,
every $50 miles the oil in the crank
case, oil pump not working properly,
or some obstruction of break in oil
passages. The engine should inn
mediately be stopped and the trou-
BILE located and remedied.
At regular intervals, as recon-
mended by the manufacturer, or, in
the abesnce of such instructions,
every $50 miles, the OF lin the crank
case reservoir should he entirely re
newed in the following manner:
First, remove drain plug in bottom
of crankcase, allowing all old oil to
drain This should preferably be
done when engine is warm, as the
old oil when heated will drain faster.
and less of it will adhere to the in
ner surfaces of the crankcase Next,
replace drain plug and pour four
quarts of Calol flushing oil into
crankcase through filler pipe Then
start and operate the engine under
its own power at a moderate idling
speed for from one to two minutes,
by which time all oil passages and
inner surfaces will have been
cleansed by the action of the flush
ing oil. Again remove drain plug
and when certain that crankcase is
thoroughly drained, replace plug
and refill crankcase reservoir with
fresh Zerolene oil as specified APP
proyimately five quarts of oil are re-
CURED for Model 40, and six quarts
for Model FB. When filling the res
eryoir through filler pipe, care
should be taken that no foreign mat
ter is carried into the engine with
the fresh oil
Valve Rocker ArmS-S-H.
Daily, or every 100 miles, put a few
drops of Zerolene No in end of
each valve rocker arm which car
ries an oil felt, and a few drops of
oil on each rocker arm center bear
ing. At the same time a few drops
of oil should be squirted on each of
the valve stems.
Electric Starting Motor-0-J.
Every 1000 miles use squirt can to
apply few drops of Zerolene No

shaft bearings. Also supply few
drops Of oil to motor pinion shaft
Electric Gcnerat0r-7-G Every
$50 miles use squirt can to apply a

CIutch-10-L. If the clutch is
slipping because of greasy or gum
my condition of the leather. il
should be thoroughly flushed with
kerosene With the engine run
ming. the clutch pedal should be
worked back and forth TO allow the
kerosene to cut and dislodge this
greasy deposit A small quantity of
auto leather clutch oil should then
be applied 10 the leather If the
clutch is inclined to grab by reason
OF the leather being hard or dry,
apply little auto leather clutch oil
to the leather This application of
oil to the leather can best be ac-
complished by blocking the clutch
pedal about halfway down The
clutch cone can then be revolved by
hand and the oil applied to the
leather at several points. Further
turning of the clutch cone will dis
tribute the oil over it's entire sur.
