WARMWEATHER STARTING (50 ° F
AND ABOVE)
When engine starts, slowly push choke
control in until the engine begins to run
smoothly. If the engine starts to run
roughly, pull the choke control out slight-
ly for a few seconds and then continue
to push the control in slowly.
The attachments and ground drive can
now be used. If the engine does not
accept the load, restart the engine and
allow it to warm up for one minute using
the choke as described above.
COLD WEATHER STARTING (50° FAND
BELOW)
When engine starts, slowly push choke
control in until the engine begins to run
smoothly. Continue to push the choke
control in small steps allowing the
engine to accept small changes in
speed and load, until the choke control
is fully in. If the engine starts to run
roughly, pull the choke control out slight-
ly for a few seconds and then continue
to push the control in slowly. This may
require an engine warm-up pedod from
several seconds to several minutes,
depending on the temperature.
AUTOMATIC TRANSMISSION WARM-UP
Before driving the unit in cold weather,
the transmission should be warmed up
as follows:
Be sure the tractor is on level ground.
Place the motion control lever in neu-
tral. Release the parking brake and
let the clutch/brake slowly return to
operating position.
Allow one minute for transmission to
warm up. This can be done duringthe
engine warm up period.
The attachments can be used during
the engine warm-up period after the
transmission has been warmed up and
may require the choke control be pulled
outslightly.
NOTE: A high altitude (above 3000 feet)
or in cold temperatures (below 32 F) the
carburetor fuel mixture may need to be
adjusted for best engine performance.
See "TO ADJUST CARBURETOR" in the
