• Turn the ignition key clockwise to the "START" position
and release it as soon as the engine starts; however,
do not crank the engine continuously for more than 5
seconds at atime If the engine does not start within
this time, turn the key to "OFF" and wait at least 15
seconds to allow the engine's starter motor to cool
Try again after waiting If after a few attempts the
engine fails to start, do not keep trying to start it with
the choke closed as this will cause flooding and make
starting more difficult
• As the engine warms up, gradually push the choke
knob downward to open the choke Do not use the
choke to enrich the fuel mixture, except as necessary to
start the engine
• Allow the engine to run for a few minutes at mid
throttle before putting the engine under load
• Observe the hour meter / indicator panel If the
battery indicator light or oil pressure light come
on, immediately stop the engine Have the tractor
inspected by your authorized MTD Service dealer
Cold Weather Starting
When starting the engine at temperatures near or below
freezing, ensure the correct viscosity motor oil is used
in the engine and the battery is fully charged Start the
engine as follows:
• Be sure the battery is in good condition A warm
battery has much more starting capacity than a cold
battery
• Use fresh winter grade fuel Winter grade gasoline
has higher volatility to improve starting Do not use
gasoline left over from summer
• Follow the previous instruction for STARTING THE
ENGINE
Using Jumper Cables To Start Engine
_ ARNINGh Batteries contain sulfuric acid and
produce explosive gasses. Make certain the
area is well ventilated, wear gloves and eye
protection, and avoid sparks or flames near
the battery.
If the battery charge is not sufficient to crank the engine,
recharge the battery. If a battery charger is unavailable
and the tractor must be started, the aid of a booster
battery will be necessary. Connect the booster battery as
follows:
Connect the end of one cable to the disabled tractor
battery's positive terminal; then connect the other end
of that cable to the booster battery's positive terminal
Connect one end of the other cable to the booster
battery's negative terminal; then connect the other end
of that cable to the frame of the disabled tractor, as far
from the battery as possible
