7) Using the left hand, pull the engine starter handle
slowly, until resistance is felt. This is the compression
point. Return the starter handle to its original position
and pull swiftly. Do not pull the rope out to its maximum,
extended length. Repeat as necessary for the engine
to start. Allow the starter handle to retract slowly. If the
engine does not start after five pulls, stop
and consult the material supplied by the engine
manufacturer.
8) Allow the engine to properly "warm up" and operate
without the requirement for engine choke. As the
engine warms up, move the choke lever up to the
right/open position (toward the fuel tank). In cold
weather, initial starting will require more pulls because
an extremely rich fuel/air mixture is required. Check for
proper centrifugal clutch operation, excessive
transmission noise and/or vibration.
9) Stopping the Hole Digger is accomplished by
releasing the twist grip throttle control to its maximum,
closed (engine idle speed) position and then turning
the engine ON/OFF ignition switch to the OFF position.
The switch is located under the fuel tank.
If the Hole Digger and/or an individual
component/accessory does not appear to be
functioning properly, STOP and do not further
operate the Hole Digger until the corrective action
has been completed. If there are any questions
regarding the proper operation of the Hole Digger,
contact the dealer or the Customer Service
Department for assistance BEFORE further
utilization. There is no charge for this service.
OPERATING THE HOLE DIGGER.
Application: All 200 Series models.
1) Do not attempt to begin digging with the Hole Digger
until the operator is ready to begin the process and is
in full control of the machine.
2) Rotate the twist grip throttle control
counterclockwise to increase the engine speed. The
auger will begin to rotate when the engine speed
reaches the centrifugal clutch initial engagement
speed.
3) Normal operating procedure for the Hole Digger is to
dig with the engine operating at full speed. This will
allow the centrifugal clutch to become more firmly
engaged. This procedure will transmit more usable
power to the auger, resulting in greater productivity and
less component wear.
When digging in areas filled with known buried
obstructions such as tree roots, rocks and other
debris, operate the Hole Digger at less than full (an
intermediate) speed to insure a more rapid release
of the centrifugal clutch when an obstruction is
encountered. This is an industry wide operating
procedure.
4) The Hole Digger is equipped with a centrifugal clutch
assembly within the transmission, designed to slip
whenever overloaded or if the auger comes in contact
with a buried obstruction. Newton’s Laws of Physics
allow the centrifugal clutch assembly to ALWAYS slip
whenever overloaded or if the auger comes in direct
contact with a buried obstruction. The term slippage is
not intended to infer that the centrifugal clutch
assembly becomes fully disengaged with no
horsepower and torque being transmitted to the auger.
In the slipping mode, a centrifugal clutch still transmits
a specific amount of horsepower and torque to the
auger. This specific amount of horsepower and torque
is directly proportional to many factors including: the
mechanical condition of the centrifugal clutch
assembly and the rotational speed of the centrifugal
clutch assembly when the initial slippage occurs. The
response time for the centrifugal clutch assembly to
react to an overload condition is directly proportional to
its rotational speed. The higher the rotational speed
(RPM) of the centrifugal clutch at the time of overload,
the greater amount of time it requires to react and
actually slip. This phenomenon is inherent with all
centrifugal clutch assemblies. It is also inherent with all
powered equipment incorporating such a device.
