Waste Disposal

Engine oil, hydraulic oil, and engine coolant are pollutants
to the environment. Dispose of these according to your
state and local regulations.

Mercury Tilt Switch

The tilt switch on this unit is located under the seat. Tilt the
seat up to gain access.
The tilt switch on this unit contains mercury, a hazardous
material. Mercury that is outside a sealed container
vaporizes at room temperature. The vapors are harmful.
Mercury can be absorbed through the skin. Do not attempt
to open or repair this switch.
A very small amount of mercury is contained in a
hermetically sealed body. The steel switch is then potted in
a hard epoxy in a plastic case. It is unlikely that the
mercury will ever escape from the enclosure. These high
performance and reliable inexpensive switches are
recyclable.
Mercury is an important and beneficial compound but
requires special care in handling and disposal. When used
and managed properly, mercury is not a threat to people or
the environment. This information is presented to users so
that they are aware that these switches contain mercury and
will apply sound disposal practices when these devices
reach their normal end of life or are damaged.

Mercury Tilt Switch Disposal

Several states have passed laws concerning the disposal of
devices containing mercury. In all the remaining states it is
advisable to follow similar procedures. The laws state that
these sealed devices contain mercury and should not be
placed in the garbage until the mercury is removed and
reused, recycled, or otherwise managed to ensure that it
does not become part of solid waste or waters. Management
and disposal practices must be within relevant federal,
state, or local laws.
Return the switch to your Toro dealer if it is faulty and is
being replaced or if the unit containing the switch is no
longer operating and is being scrapped. If the switch is
damaged or broken open, use extreme caution in handling.
Call your local waste management authority or Toro
Customer Service for instructions.
Caution
The mercury contained in the tilt switch is
poisonous and exposure to mercury can cause
severe illness.
Never attempt to open or repair the tilt
switch.
Avoid contact with the mercury.
