PERCUSSION SELECTOR
The percussion function can be turned on and off.
To select , push on the collar against the spring tension to disengage
the teeth from the slots and turn to either the "Hammer" symbol for
soft percussion or the "No Hammer" symbol to turn the percussion OFF.
The main purpose of soft percussion function on this machine is to keep
the diamond segments sharp. If the bit is staying sharp without it, the
percussion function may be turned off. If the bit glazes easily, it should be turned on.
THE SWITCH
The machine has a lockable trigger switch. Squeeze the trigger to start
the machine. To lock the switch on, press the lock button while holding
the trigger switch on. To release, squeeze the trigger and release.
WARNING: Never lock the switch on when drilling hand-held. Only
lock the switch on when mounted to a rig.
OVERLOAD PROTECTION AND OVERHEAT PROTECTION
Overload:
If the excessive load is sustained too long, the motor will shut down completely. In this case, the motor must be
restarted by turning OFF and then back ON the switch.
Overheat Thermal Protection:
If the temperature of the motor gets too high, the thermal protection will shut the motor down. When this
happens, do not immediately put a load on the motor after restarting. Always run the machine at no load for a
few minutes to return to a normal operating temperature before continuing.
CAUTION: The motor will be damaged if it is repeatedly overloaded or overheated. Always cool the
motor by running at no load for a few minutes whenever it stops from either overheat or overload.
SAFETY CLUTCH
This machine is equipped with a mechanical clutch to protect the operator and machine from excessive torque
forces. After the clutch slips many times, it will become worn and slip at lower and lower torque levels. When
this happens, it must be serviced by an authorized service provider. The recommended torque of the clutch nut
is 21 Nm.
DIAMOND CORE DRILLING
