c CAUTION: Avoid injury! Do not use hands or feet to clear

plugged mower deck or blower assembly. Stored energy can cause

blades to rotate.

c CAUTION: Avoid injury! Use extra care when loading or

unloading the machine onto a trailer or truck. Machine wheels can

go off the ramp or trailer, causing the machine to tip over.

• To load, back slowly and in a straight line. Keep wheels away

from drop-offs and edges.

• Do not use two separate loading ramps. Use a full width

loading ramp at least 30 cm (12 in.) wider than machine to keep

castor wheels from going off the ramp edge.

• Use a trailer with sides.

IMPORTANT: Avoid damage! Operating in extreme conditions

may require more frequent service intervals:

• Engine components may become dirty or plugged when

operating in extreme heat, dust or other severe conditions.

• Engine oil can degrade if machine is operated constantly at slow

or low engine speeds or for frequent short periods of time.
