(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 storage 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

MOWING
TIPS
• Tire chains cannot be used when the mower housing isat-
tached to unit.
• Mower should be properly leveled for best mowing per-
formance.
See TO LEVEL MOWER HOUSING"in
the
Service and Adjustments section of this manual
° Use the runner on the right hand side of mower as a guide.
The blade cuts approximately an inch outside the runner
(See FIG. 15).
° The left hand side of mower should be used for trimming.
• Drive so that clippings ere discharged onto the area that
has been cut. Have the cut area to the right of the ma-
chine. This will result in a more even distribution of clip-
pings and more uniform cutting
° When mowing large areas, start by turning to the right so
that clippings will discharge away from shrubs,, fences.
driveways, etc. After one or two rounds, mow in the oppo-
site direction making left hand turns until finished (See
FIG, 17).
FIG. 17
• If grass is extremely tall, it should be mowed twice to re-
duce load and possible fire hazard from dried clippings.
Make first cut relatively high, the second to the desired
height.
° Do not mow grass when it iswet, Wet grass will plug mow-
er and leave undesirable clumps. Allow grass to dry be-
fore mowing.
° Always operate engine at full throttle when mowing to as-
sure better mowing performance and proper discharge of
material.
Regulate ground speed by selecting
a low
enough gear to give the mower cutting performance 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-
tachrnent being used.
