■^NOTE
At no time should the high-speed adjustment
screw be less than 1-3/8 turns from the closed
position or greater than 1-1/2 turns from the
closed position.
If the engine does not run correctly between 1-3/8
and 1-1/2, the high-speed adjustment valve must be
replaced.
IDLE SPEED ADJUSTMENT (All Tractors)
Run engine at maximum governed, no load speed for
a minimum of 30 seconds, then allow engine speed to
fall to idle or put throttle into idle position. Set engine
speed to 1800 (+ or - 75 RPM) by turning the idle
speed screw in or out.
IDLE FUEL ADJUSTMENT (All Tractors)
Set the idle fuel mixture by turning the idle fuel screw

MAINTENANCE
ENGINE OIL
The engine crankcase is filled with ship-away oil. This
oil may be used for the first 5 hours of engine
operation at temperatures between 0 degrees F. and
90 degrees F.
If temperatures are not within this
range, drain the oil from the oil filter and crankcase and
replace with new oil as specified in the "LUBRICATION
TABLE".
To aid starting, the selection of crankcase lubricating
oils should be based on the lowest anticipated
temperatures until the next drain period.
Cub Cadet Low Ash Engine Oil meeting API Service
Classification SF is recommended. For maximum en -
gine life select API SF oils with lowest levels of barium,
calcium, or magnesium additives and minimum ash
content {approximately 0.5%). Lubricant suppliers will
normally furnish this Information on their engine oils.
Multi-viscosity numbered oils such as SAE 10W-30 or
SAE 10W-40 can be used above 32 degrees Fahren -
heit.
Regularly check the oil level of the engine crankcase
to see that It is filled to the correct level. Always keep
the oil level between the "FULL" and the "LOW"
marks on the dipstick. When checking the oil lever the
dipstick must be withdrawn and wiped clean, then in¬
serted all the way and withdrawn for a true reading.
■i^NOTE
Check the oil level only while the engine is
stopped and tractor is level.
■^NOTE
During initial break-in period the engine oil
level should be checked frecuently.
FILLING THE CRANKCASE
To fill the crankcase with oil, place the tractor on a level
surface. Clean the area around the oil fill tube and
dipstick to prevent debris from entering the crank -
case.
■^NOTE
Never overfill the engine crankcase. Engine
may overheat and/or damage may result if the
crankcase is below the "LOW" mark or over
the "FULL" mark. For oil capacity refer to the
"SPECIFICATIONS" and "LUBRICATION
TABLE" sections.
Remove the oil fill cap and dipstick and fill to the full
mark on the dipstick. POUR SLOWLY. Capacity is 4
pints. When checking the oil level, push the dipstick
assembly firmly but slowly until cap bottoms on tube.
DO NOT OVERFILL. Dipstick assembly MUST BE
PUSHED FULLY INTO TUBE AT ALL TIMES WHEN
ENGINE IS OPERATING.
HYDROSTATIC DRIVE HYDRAULIC FLUID FILTER
(1210 and 1211 Tractors Only)
■^NOTE
Clean the outside area before removing the
filter to keep dirt from getting into the trans -
mission case. If a mower is mounted on the
tractor, the mower must be lowered to facili -
tate removal of the filter.
Remove the throw away can type filter and replace
with a new filter after the first 10 and 50 hours of
operation, and every 100 hours of operation there¬
after.
