Toro TRX-20 Operator's Manual page 5

•
Ensure that you operate the machine in areas where
there are no obstacles in close proximity to the operator.
Failure to maintain adequate distance from trees, walls,
and other barriers may result in injury as the machine
backs up during operation if the operator is not attentive
to the surroundings. Only operate the unit in areas where
there is sufficient clearance for the operator to safely
maneuver the product.
•
Before digging, have the area marked for underground
utilities, and do not dig in marked areas.
•
Locate the pinch point areas marked on the machine and
keep hands and feet away from these areas.
•
Lightning can cause severe injury or death. If lightning
is seen or thunder is heard in the area, do not operate
the machine; seek shelter.
Slope Operation
Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or death.
All slopes require extra caution.
•
Do not operate the machine on hillsides or slopes
exceeding the angles recommended in the following table.
Front Facing Rear Facing Uphill Side Facing Uphill
Uphill
13°
Note: See also the Slope Indicator (page 7).
•
Operate up and down slopes with the front end of
the machine uphill.
•
Remove obstacles such as rocks, tree limbs, etc. from the
work area. Watch for holes, ruts, or bumps, as uneven
terrain could overturn the machine. Tall grass can hide
obstacles.
•
Use only Toro-approved accessories. Accessories can
change the stability and the operating characteristics
of the machine. Warranty may be voided if used with
unapproved accessories.
•
Keep all movements on slopes slow and gradual. Do not
make sudden changes in speed or direction.
•
Avoid starting or stopping on a slope. If the machine
loses traction, proceed slowly, straight down the slope.
•
Avoid turning on slopes. If you must turn, turn slowly
and keep the heavy end of the machine uphill.
•
Do not operate near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a track goes
over the edge of a cliff or ditch, or if an edge caves in.
•
Do not operate on wet grass. Reduced traction could
cause sliding.
•
Do not park the machine on a hillside or slope without
lowering the boom to the ground, setting the parking
brake, and chocking the tracks.
