AUTOMATIC TRANSMISSION WARM-UP

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 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 while 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 shipping of your tractor.

IMPORTANT: Should your trensmission require removal 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 _osition and hold for five (5) seconds.

ove 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 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 of 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 retum 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.
