Operation - McCulloch MC1136 Owner's Manual

CAUTION: Alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract moisture which
leads to sep a ra tion and for ma tion of acids during stor-
age. Acidic gas can damage the fuel system of an engine
while in storage. To avoid engine problems, the fuel
sys tem 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 In struc tions for
additional information. Never use engine or carburetor
cleaner products in the fuel tank or permanent damage
may occur.
TO START ENGINE (See Fig. 5)
When starting the engine for the fi rst 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.
• Sit on seat in operating position, depress clutch/brake
pedal and set parking brake.
• Place gear shift lever in neutral (N) position.
• Move attachment clutch to "DISENGAGED" position.
• Move throttle control to choke position.
NOTE: Before starting, read the warm and cold starting
procedures below.
• Insert key into ignition and turn key clockwise to "START"
position and release key as soon as engine starts.
Do not run starter continuously for more than fi fteen
sec onds per minute. If the engine does not start after
several attempts, move throttle control to fast position,
wait a few minutes and try again. If engine still does
not start, move the throttle control back to the choke
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 position until the engine
runs roughly, then move throttle control to fast posi-
tion. This may require an engine warm-up period from
several seconds to several minutes, depending on the
tem per a ture.
• The attachments can also be used during the engine
warm-up period.
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.

MOWING TIPS
• Tire chains cannot be used when the mower hous ing
is attached to tractor.
• Mower should be properly leveled for best mowing per-
for mance. See "TO LEVEL MOWER HOUSING" in the
Service and Adjustments section of this manual.
• The left hand side of mower should be used for trim-
ming.
• Drive so that clippings are discharged onto the area
that has been cut. Have the cut area to the right of the
machine. This will result in a more even dis tri bu tion of
clippings and more uniform cutting.
• When mowing large areas, start by turning to the right so
that clippings will discharge away from shrubs, fences,
drive ways, etc. After one or two rounds, mow in the
opposite direction making left hand turns until fi nished
(See Fig. 7 ).
• If grass is extremely tall, it should be mowed twice to
reduce load and possible fi re hazard from dried clip-
pings. Make fi rst cut relatively high; the second to the
desired height.
• Do not mow grass when it is wet. Wet grass will plug
mower and leave undesirable clumps. Allow grass to
dry before mowing.
• Always operate engine at full throttle when mow-
ing to assure better mowing performance and proper
dis charge of ma te ri al. Regulate ground speed by se-
lect ing a low enough gear to give the mower cut ting
per for mance as well as the quality of cut desired.
• When operating attachments, select a ground speed
that will suit the terrain and give best performance of
the at tach ment being used.
