Purge Transmission - Craftsman 917.273220 Owner's Manual

WARM WEATHER STARTING (50 ° F
AND ABOVE)
• When engine starts, slowly push choke
control in untilthe 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 ° F AND
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 period 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 during the
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
out slightly.
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
Service and Adjustments section of this
manual.
PURGE TRANSMISSION
_,CAUTION: Never engage or disen-
gage freewheel lever whUe the engine is
running.
To ensure proper operation and perfor-
mance, it is recommended that the trans-
mission be purged before operating tractor
for the first time. This procedure will
remove any trapped air inside the trans-
mission which may have developed during
shippingof your tractor.
IMPORTANT: Should your transmission
require removeal for service or replace-
ment, it should be purged after reinstalla-
tion before operating the tractor.
• Place tractor safely on level surface with
engine off and parking brake set.
• Disengage transmission by placing free-
wheel control in freewheehng position
(See =TO TRANSPORT" in this section
of manual).
• Sitting in the tractor seat, start engine.
After the engine is running, move throt-
tle control to slow position. With motion
control lever in neutral (N) position,
slowly disengage clutch/brake pedal.
• Move motion control lever to full forward
position and hold for five (5) seconds.
Move lever to full reverse position and
hold for five (5) seconds. Repeat'this
procedure throe (3) times.
NOTE: During this procedure there will be
no movement of drive wheels. The air is
being removed from hydraulic drive sys-
tem.
• Move motion control lever to neutral (N)
position. Shut off engine and set parking
brake.
• Engage transmission by placing free-
wheel control in driving position (See
"TO TRANSPORT" in this section cf
manual).
• Sitting in the tractor seat, start engine.
After the engine is running, move throt-
tle control to half (1/2) speed. With
motion control lever in neutral (N) posi-
tion, slowly disengage clutch/brake
pedal.
• Slowly move motion control lever for-
ward; after the tractor moves approxi-
mately five (5) feet, slowly move motion
control lever to reverse position. After
the tractor moves approximately five (5)
feet return the motion control lever to
the neutral (N) position. Repeat this pro-
cedure with the motion control lever
three (3) times.
• Your tractor is now purged and now
ready for normal operation.
