A bolt torqued to 25 N∙m (18 ft-lb) is very
tight. While holding the impeller, put your weight
behind the torque wrench, and tighten the bolt.

Operating Tips

General Mowing Tips
•
Place the hoop of the footstop under the upstop to
increase handling of the machine.
•
Inspect the area where you will use the machine
and remove all objects that the machine could
throw.
•
Avoid striking solid objects with the cutting line.
Never deliberately mow over any object.
•
If the machine strikes an object or starts to vibrate,
immediately shut off the engine, disconnect
the wire from the spark plug, and examine the
machine for damage.
•
For best performance, install new cutting lines
before the cutting season begins.

•
Replace the cutting line as needed with a Toro
replacement cutting line.
•
Ensure that the replacement cutting line is the
same length as the intact cutting line.
Cutting Grass
•
Cut only about a third of the grass blade at a time.
Do not cut below the highest setting (30 mm or
1-1/4 inches) unless the grass is sparse, or it is

•
Do not mow grass over 15 cm (6 inches) long
because the machine may plug or the engine may
stall.
•
Wet grass and leaves tend to clump on the yard
and can cause the machine to plug or the engine
to stall. Mow only in dry conditions if possible.
WARNING
Wet grass or leaves can cause serious
injury if you slip and contact the cutting
line.
Mow only in dry conditions if possible.
•
Be aware of a potential fire hazard in very dry
conditions, follow all local fire warnings, and keep
the machine free of dry grass and leaf debris.
•
If the finished lawn appearance is unsatisfactory,
try 1 or more of the following:
– Inspect the cutting unit and/or replace the
cutting line.
– Walk at a slower pace while mowing.
– Raise the cutting height on your machine.
– Cut the grass more frequently.
– Overlap cutting swaths instead of cutting a full
swath with each pass.

Cutting Leaves
•
After cutting the lawn, ensure that half of the lawn
shows through the cut leaf cover. You may need
to make more than a single pass over the leaves.
•
Mowing grass over 15 cm (6 inches) in length is
not recommended. If the leaf cover is too thick, the
machine may plug and cause the engine to stall.
•
Slow down your mowing speed if the machine
does not cut the leaves finely enough.
