• Use care when loading or unloading the machine
into a trailer or truck.
• Use care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
• Ensure that the area is clear of other people before
operating the machine. Stop the machine if anyone
enters the area.
• Never leave a running machine unattended. Always
lower the boom, stop the engine, set the parking
brake, and remove the key before leaving.
• Never jerk the controls; use a steady motion.
• Watch for traffic when operating near or crossing
roadways.
• Do not touch parts which may be hot from
operation. Allow them to cool before attempting to
maintain, adjust, or service.
• 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.

• Operate up and down slopes with the front end

• 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.
Maintenance and Storage
• Disengage the trencher hydraulics, lower the boom,
set the parking brake, stop the engine, and remove
the key. Wait for all movement to stop before
adjusting, cleaning, or repairing.
• Clean debris from the chain, digging teeth, boom,
trencher head, drives, mufflers, and engine to help
prevent fires. Clean up oil or fuel spillage.
• Let the engine cool before storing and do not store
near flame.
• Do not store fuel near flames or drain indoors.
• Park the machine on level ground. Never allow
untrained personnel to service the machine.
• Use jack stands to support components when
required.
• Carefully release pressure from components with
stored energy.
• Disconnect the battery (electric start models only)
or remove the spark plug wires before making
any repairs. Disconnect the negative terminal first
and the positive last. Reconnect positive first and
negative last.
