4. Operations
a. To start trenching, set throttle full open. Before engaging the clutch lever, the
handle must be pushed toward the ground enough to allow the rotor to turn
without hitting the ground. Engage clutch and when rotor attains operating speed,
the handle should be raised slowly so that the rotor engages the ground and
gradually digs to trench depth.
b. When trench depth is achieved, the operator should pull the machine to the rear
at such a speed that the trencher will dig without overloading the engine.
WARNING:
Starting the trench is the most critical time for dangerous flying
projectiles. Be especially cautious by policing the area for rocks or other possible
projectiles and ensure the area is completely clear of people, animals, vehicles,
etc. that may be damaged by projectiles.
c. When trenching, if trencher strikes an underground object, stop immediately to
determine what the object is. Investigation should be done visually since touching
an exposed electric wire could be fatal.
d. When trencher strikes a rock, either the trench or rock should be moved.
e. When digging in extremely hard clay or other difficult soils, it may sometimes be
necessary to use an oscillating action by applying and releasing pressure on
handlebar, front to rear, alternately.
