INTRODUCTION
It is your responsibility as the operator or helper of this piece of equipment
to know what specific requirements, precautions and work hazards that may
exist on each job. You must read and understand all of the information
contained in the operator’s manual and inform any person who might be
assisting you.
The two-man earth drill is a unique tool, in that it is one of, if not the only
hand held tool that requires the use of two people to operate it. For this
reason you must be sure of the capabilities of the person assisting you. You
must be sure that both you and your assistant understand the use of the tool
and the risks involved.
NOTE: This machine is designed to drill holes in soil. It is not intended for
any other purpose.
The rotation of the auger or drill bit on any type of earth drill will cause a counter
rotation of the handle bars while drilling a hole. The force exerted on the operator will
vary according to the type of soil, the diameter of the auger and the condition of the
machine.
The force exerted on the operators will vary according to the type of soil,
the diameter of the auger and the condition of the machine. In the event that
the auger bit should encounter an object that stops the rotation suddenly,
the digging force will be transmitted directly to the operators. For this
reason, the operators must have secure footing and control of the machine
and be mentally and physically prepared to react to this force.
Because the C-71-5 is a hand operated, portable type machine, it is limited
in what it is capable of doing. The job site, soil conditions, job specifications
and operator experience may dictate that a different tool or method be used
to do the job.
NOTE: It is not recommended that engines of higherhorse power be
installed on this machine. Consult the factory before making any
modifications.
