BASIC OPERATION
NOTE: Make sure that the power circuit voltage is the same as that shown on the specification plate of
the machine and that switch is “OFF” before connecting the tool to the power circuit.
Connect the motor to the converter before turning the converter on.
The connection between the power converter and the motor is by a special motor coupling cable. To connect,
unscrew the cap, align the tangs, push in, and screw on the collar. Take care to avoid bending the pins. Keep
the cap on when not in use. Do not alter this plug in any way.
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.
CAUTION: After the machine has been switched off, the spindle
will continue rotating. Take care that parts of your body do not
come into contact with the rotating parts or set the machine
down while it is still rotating!
HOW TO USE THE TOOL
Effective control of this machine requires two-handed operation for maximum protection and resistance to
the start-up and operating torque. Place the work properly and hold the machine firmly WITH BOTH HANDS
to prevent loss of control, which could cause personal injury. Protect your eyes from injury with safety glasses
or goggles.
OVERLOAD PROTECTION, OVERHEAT PROTECTION
Overload & Load Warning Lamp
When operating within the normal load range, the load warning lamp will glow green.
When full load is reached, the load warning lamp will flash red. If full load is exceeded and sustained for too
long, the motor will shut down and the load warning lamp will glow solid red. In this case, the motor must be
first shut off and then restarted. When this happens, the motor will very likely be near overheating, so it is
also a good idea to run the motor at no load for a few minutes to cool it before continuing.
Overheat Thermal Protection
If the temperature of the motor gets too high, the thermal protection will shut the motor down. The switch
must be first shut off and then restarted. When this happens, do not immediately start working after restarting
the motor. Always run the machine at no load for a few minutes to return to a normal operating temperature
before continuing. (Also see below the section: "POWER CONVERTER LCD SCREEN CODES")
