DANGER
There may be buried power, gas, and/or telephone
lines in the work area. Shock or explosion may
occur if you dig into them.
Have the property or work area marked for buried
lines and do not dig in marked areas. Contact your
local marking service or utility company to have the
property marked (for example, in the United States,
call 811 for the nationwide marking service).
DANGER
The moving teeth and auger will severely cut hands,
feet, or other body parts.
•
Keep hands, feet, and any other part of your
body or clothing away from moving teeth, auger,
or other parts.
•
Before adjusting, cleaning, repairing, or
inspecting the trencher, lower the trencher to
the ground, stop the engine, wait for all moving
parts to stop, and remove the key.
WARNING
When the engine is off, attachments in the raised
position can gradually lower. Someone nearby may
be pinned or injured by the attachment as it lowers.
Always lower the attachment lift each time you shut
off the traction unit.
WARNING
When going up or down hill, the machine could
overturn if the heavy end is toward the downhill
side. Someone may be pinned or seriously injured
by the machine if it overturns.
Operate up and down slopes with the heavy end of
the machine uphill. An attached trencher will make
the front end heavy.
