Basic working techniques

Overload
NOTICE! Do not repeatedly overload the machine. This can damage the machine. The machine's load indicator shows
the power output and does not necessarily give the best recommendation for an optimal logging.
• In the event of overloading the motor, the load must be reduced so that the motor resumes normal rpm.
• If the drill bit jams, the mechanical slip clutch protects the gearbox before the electronics disconnects the power.
