Carburetor; Removal - Craftsman EZ3 917.259531 Owner's Manual

OPERATmON
ADD GASOLINE
o Fill fuel tank Use fresh, clean, regular unleaded
gasoline with a minimum of 87 octane° (Use of leaded
gasoline will irrcrease 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 gasohol 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_

CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
!
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.
TO START EI_GINE (See Fig. 9)
When starting the engine for the first time or if the engine
has run out of fuel, 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 clutch/brake
pedal and set parking brake.
, Place motion control lever in neutral (N) position.
° Move attachment clutch to "DISENGAGED" position.
. Move throttle control to choke (l\l) position.
Note: Before starting, read the warn] and cold starting
procedures below.
o .... _t mt_
Insertkey rote tgnltlonand turn key clockwise to STAR
position arrd 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 (',_)
position, wait afewminutesandtryaga n. 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)
o When engine starts, move the throttle control t0 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 thethrottle
control in the choke (l\l) position until the engine runs
roughly, then move throttle control to fast (,,_) position.
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 urfit in cold weather, the transmission
should be warmed up as follows:
o Be sure the tractor is on level ground_
• Place the motion control lever in neutral 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 also be used during the engine
warm-up per_odafter the transmission has been warmed
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

PURGE TRANSMISSION
_ CAUTION: Neverengageordisengage I
freewheel lever while the engine is run-
ning.
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 REINSTALLATION
BEFORE OPERATING THE TRACTOR
° Place tractor safely on level surface with engine off and
parking brake set.
o Disengage transmission by' placing freewheel control
in freewheeling position (See ''TO TRANSPORT" in
this section of manual).
o Sitting in the tractor seat, start engine. After the engine
s running move throttle control to slow (._,) position.
With motion control lever in neutra (N) position, slow y
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.
