ADD GASOLINE

Fill fuel tank Use fresh, dean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline win increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness.

IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING

WARNING: Experience indicates that alcohol blended fuels (called gasohof or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before stor- age of 30 days or longer, Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instruc- tions for'additional information, Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur

filler neck. Do not overfill. Wipe off any

spilled oil or fuel. Do not store, spill or CAUTION: Fill to bottom of gas tank use gasoline near an open flame.

TO START ENGINE (See Fig. 9)

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

. Be sure freewheel control is in the transmission en- gaged position.

. Sit on seat in operating position, depress clutchtbrake pedal and set parking brake.

. Place motion control lever in neutral (N) position. Move attachment clutch to "DISENGAGED" position.

Move throttle control to choke (N) position.

Note: Before starting, read the warm and cold starting procedures below,

Insert key into ignition and tum key clockwise to"START"

position and release key as soon as engine starts. Do not run starter continuously for more than fifteen sec_ onds per minute If the engine does not start after several attempts, move throttle control to fast (,t_) position, wait a few minutes and try again. If engine still does not start, move the throttle control back to the choke (N) position and retry.

WARM WEATHER STARTING (50 ° F and above)

When engine starts, move the throttle control to the fast (._) position.

-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, allow engine to run with the throttle control in the choke (\I) position until the engine runs rough y, then move thrott e contro to fast (,,t_) post on.

This may require an engine warm-up period from several seconds to several minutes, depending on the tempe_ature._

HYDROSTATIC TRANSMISSION WARM UP

oBefore driving the unit in cold weather, the transmission should be warmed up as follows:

,,Be sure the tractor is on level ground_

o Place the motion control ]ever in neutral. Release

the parking brake and let the clutch/brake slowly return to operating position.

• Atfowoneminutefortransmissiontowarmup. This can be done during the engine warm up period.

,,The attachments can also be used during the engine warm-up period after the transmission has been war reed up_

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'TO ADJUST CARBURETOR" in the Service and Adjustments section of this manual°

PURGE TRANSMISSION

freewheel lever while the engine is run-

CAUTION: Never engage or disengage I

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 iemove 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 pa_rking brake set,

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

°Sitting in the tractor seat, start engineo After the engine is running, move throttle control to slow (,,_,) position. With motion control lever in neutral (N) position, slowly disengage clutchlbrake 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.

oMove motion control lever to neutral (N) position° Shut- off engine and set parking brake

oEngage transmission by placing freewheel control in driving position (See "TO TRANSPORT" in this section of manual),
