protect them selves and others from serious injury.
Follow the manufacturer's recommendation for wheel
weights or counterweights.
Keep machine free of grass , leaves or other debris
build-up which can touch hot exhaust / engine parts

or other debris which can cause build-up to occur.
Clean any oil or fuel spillage before operating or
storing the machine. Allow machine to cool before
storage.
II. SLOPE OPERATION
Slopes are a major factor related to loss of control and
tip-over accidents, which can result in severe injury or
death. Operation on all slopes requires extra caution. If
you cannot back up the slope or if you feel uneasy on it,
do not mow it.
Mow up and down slopes, not across.
Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.
Choose a low ground speed so that you will not have
to stop or shift while on the slope.
Do not mow on wet grass. Tires may lose traction.
Always keep the machine in gear when going down
slopes. Do not shift to neutral and coast downhill.
Avoid starting, stopping, or turning on a slope. If the
tires lose traction, disengage the blades and proceed
slowly straight down the slope.
Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction,
which could cause the machine to roll over.
Use extra care while operating machine with grass
catchers or other at tach ments; they can affect the
stability of the machine. Do no use on steep slopes.
Do not try to stabilize the machine by putting your foot
on the ground.
Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly roll over if a wheel is over
the edge or if the edge caves in.
