Craftsman 917.259172 manual Purge Transmission, Hydrostatic Transmission Warm UP

OPERATION

TO START ENGINE (See Fig. 7)

When starting the engine for the first time or if the engine has run out of fuel, itwill take extra cranking time to move fuel from the tank to the engine.

•Be sure freewheel control is in the transmission engaged position.

,Sit on seat in operating position, depress clutch/ brake pedal and set parking brake°

•Place motion control lever in neutral (N) position.

°Move attachment clutch to "DISENGAGED" posi- tion,.

•Move throttle control to fast position

=Pull choke control out for a cold engine start at- tempt. For a warm engine start attempt the choke control may not be needed.

Note: Before starting, read the warn] and cold starting procedures below.

°Insert key into ignition and turn key cloctcwise to "START" position and release key as soon as engine starts. Do not run starter continuously for more than fifteen seconds per minute. If the engine does not start after several attempts, push choke control in, wait a few minutes and try again° if engine still does not start, pull the choke control out and retry.

WARM WEATHER 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 slightly for a few seconds and then continue to

push the control in slowly.

oThe 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)

oWhen engine starts, slowly push choke control in until the engine begins to run srnoothly. 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_ Ifthe engine starts to run roughly, pull the choke control out slightly 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°

HYDROSTATIC TRANSMISSION WARM UP

•Before driving the unit in cold weather, the trans- mission should be warmed up as follows:

o Be sure the tractor is on level ground.

=Place the motion control lever in neutral. R e- lease 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 warmedup and may require the choke control be pulled out slightly.

NOTE: If at 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 '_roADJUST CARBURETOR" in the Service and

Adjustments section of this manual_

PURGE TRANSMISSION

To ensure proper operation and performance, it is recom- mended that the transmission be purged before operating tractor for the first time_ This procedure will remove any trapped air inside the transmission which may have devel-

oped during shipping of your tractor.

IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE

REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATtON

BEFORE OPERATING THE TRACTOR_

°Place tractor safely on level surface with engine off and parking brake seL

°Disengage transmission by placing freewheel control in freewheeling position (See "TO TRANSPORT" in this section of manual)°

=Sitting in the tractor seat, start engine. After the engine is running, move throttle 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 three (3) times.

NOTE: During this procedure there will be no movement of drive wheels. The air is being removed from hydraulic drive

system.

°Move motion controllever to neutral (N) position. Shut- off engine and set parking brake.

°Engage transmission by placing freewheel control in driving position (See "TO TRANSPORT" in this section of manual)_

•Sitting in the tractor seat, startengine. After the engine is running, move throttle control to half (1/2) speed. With motion control lever'in neutral (N) position, slowly disengage clutch/brake pedal.

°Slowly move motion control lever forward, after'the tractor'moves approximately five (5) feet, slowly move motion control lever to reverse position° After the tractor moves approximately five (5) feet return the motion control lever'tothe neutral (N) position. Repeat

this procedure with the motion control lever'three (3) times.

°Your tractor is now purged and now ready for normal operation.
